Climate change is taking over the news - in case you hadn't noticed

I keep reading psychologists warning that talking about how terrible climate change will be is counterproductive. Rather than causing the deniers to see the error of their ways, it just makes them close their minds to further argument.

So this column isn’t for them. Rather, it’s to speak to the rest of us – those who don’t try to tell the scientists they’ve got it all wrong – to review the latest evidence that climate change is already upon us (what sane person could not have realised it?) and getting worse as each year flashes by our eyes.

I fear for my five grandkids’ future (as I may have mentioned before) but, to tell the truth, I’m glad I’ll be dead and gone before it reaches its worst. What we must do, like all those who voted teal at the last election, is to press both major parties to speed up our efforts and make Australia a leader rather than a laggard in the global push to limit how bad it gets.

Professor Albert Van Dijk of the Australian National University, an expert on precipitation, is part of an international team of researchers who’ve issued a report, the Global Water Monitor, using data from thousands of ground stations and satellites to document the effect of last year’s record heat on the world’s water cycle.

“We found global warming is profoundly changing the water cycle,” he says. “As a result, we are seeing more rapid and severe droughts, as well as more severe storms and flood events.”

Van Dijk says the most obvious sign of the climate crisis is the unprecedented heatwaves that swept the globe in 2023. Some 77 countries experienced their highest average annual temperature in at least 45 years. This “gave us a glimpse of what a typical year with 1.5 degrees Celsius of warming may look like,” he says. Warming consistently more than 1.5 degrees above pre-industrial levels is expected to have extreme and irreversible impacts on the Earth’s system.

“The high temperatures were often accompanied by very low air humidity. The relative air humidity of the global land surface was the second-driest on record in 2023. Rapid drying of farms and forests caused crops to fail and forests to burn.

“Lack of rain and soaring temperatures intensified multi-year droughts in vulnerable regions such as South America, the Horn of Africa and the Mediterranean ... This continuing trend towards drier conditions is threatening agriculture, biodiversity and overall water security.”

Get this: “The world’s forests have been soaking up a lot of our fossil fuel emissions. That’s because plant photosynthesis absorbs carbon dioxide from the atmosphere. Large disturbances like fire and drought reduce or even reverse that function.”

Rising sea surface and air temperatures have been intensifying the strength and rainfall intensity of monsoons, cyclones and other storm systems, Van Dijk adds.

We saw this when Cyclone Jasper battered northern Queensland and severe storms formed in south-east Queensland, leaving a trail of destruction. The cyclone moved much slower than expected, causing torrential rains and widespread flooding.

Enough of that. Australia’s Climate Council, a community funded organisation created by former members of the Climate Commission after it was abolished by the Abbott government in 2013, has created a “heat map” using thousands of data points from the CSIRO and help from the Bureau of Meteorology.

If we assume, perhaps optimistically, that all countries meet their present UN commitments to reduce emissions, the heat map predicts that western Sydney will swelter through twice as many days above 35 degrees and three weeks above 35 degrees every summer.

Temperatures will be worsened by the “urban heat-island effect”, as materials such as asphalt and concrete amplify heat by as much as 10 degrees during extreme heat.

Melbourne, too, faces double the number of days above 35 degrees by 2050. Will it take that long for the Australian Open to be moved?

Which brings us to last month, when six transmission line towers in Victoria were destroyed by extreme wind gusts from thunderstorms, leading to about 500,000 people losing power. The intense winds knocked trees onto local power lines or toppled the poles. Some people went without electricity for more than a week.

A month earlier, severe thunderstorms and wind took out five transmission towers in Western Australia and caused widespread outages. In January 2020, storms caused the collapse of six transmission towers in Victoria.

And, of course, in 2016 all of South Australia lost power for several hours after extreme winds damaged many transmission towers.

Recent research by Dr Andrew Dowdy and Andrew Brown, of the University of Melbourne, suggests that climate change is likely to cause more favourable conditions for thunderstorms with damaging winds, particularly in inland regions. But more research is needed to confirm this.

Van Dijk gets the last word: “Overall, 2023 provided a stark reminder of the consequences of our continued reliance on fossil fuels and the urgent need but apparent inability of humanity to act decisively to cut greenhouse gas emissions.”

We can't escape a carbon tax, which is good news, not bad

When economists are at their best, they speak truth to power. And that’s just what two of our best economists, Professor Ross Garnaut and Rod Sims, did this week. In their own polite way, they spoke out against the blatant self-interest of our (largely foreign-owned) fossil fuel industry.

They sought to counter the decade of damage done by the former federal Liberal government which, for short-sighted political gain, engaged in populist demonisation of Julia Gillard’s carbon tax.

And, by their willingness to call for a new “carbon solution levy”, they shamed the present Labor government, which dare not even mention a carbon price and isn’t game to take more than baby steps in the right direction, for fear of what Peter Dutton might say.

But the two men’s message is actually far more positive than that. In launching a new think tank, the Superpower Institute, they pursue Garnaut’s vision of how we can turn the threat of climate change into an opportunity to revitalise our economy, raising our productivity and our living standards.

Sims, former boss of the competition watchdog, says that, following a decade of stagnant production per person, real wages and living standards, Australia’s full participation in the world’s move to achieve net-zero global emissions is the only credible path to restoring productivity improvement and rising living standards.

Climate change is a threat to our climate, obviously. But it’s also a threat to our livelihood because Australia is one of the world’s largest exporters of fossil fuels. Garnaut points out that, as the rest of the world moves to renewables, two of our three largest export industries will phase out.

This will send our productivity backwards, he notes – as all the big-business people reading us lectures about productivity never do.

The good news, however, is that “putting Australia back on a path to rising productivity and living standards doesn’t mean going back to the way things were”. It’s now clear that “Australia’s advantages in the emerging zero-carbon world economy are so large that they define the most credible path to restoration of growth in Australian living standards.”

Garnaut says that “In designing policies to secure our own decarbonisation, we now have to give a large place to Australia’s opportunity to be the renewable energy superpower of the zero-carbon world economy.”

Other countries do not share our natural endowments of wind and solar energy resources, land to deploy them, as well as land to grow “biomass” – plant material – sustainably as an alternative to petroleum and coal for the manufacture of chemicals.

From a cost perspective, we are the natural location to produce a substantial proportion of the products presently made with large carbon emissions in North-East Asia and Europe.

The Superpower Institute champions a “market-based” solution to the climate challenge. We shouldn’t be following the Americans by funding the transition from budget deficits, nor become inward looking and protectionist.

Rather, everything that can be left to competitive markets should be, while everything that only governments can do – providing “public goods” and regulating natural monopolies – should be done by the government.

Sims notes a truth that, since Tony Abbott’s successful demonisation of the carbon tax, neither side of politics wants to acknowledge, that markets only work effectively if firms are required to pay the costs that their activities impose on others and, on the other hand, if firms are rewarded for the benefits their activities confer on others.

When the producers of fossil fuels don’t bear the cost of the damage their emissions of greenhouse gasses do to the climate, and the producers of renewable energy don’t enjoy the monetary benefit of not damaging the environment, these two “externalities” – one bad, the other good – constitute “market failure”.

And the way to make the market work as it should is for the government to use some kind of “price on carbon” – whether a literal tax on carbon, or its close cousin, an emissions trading scheme – to internalise those two externalities to the prices paid by fossil fuel producers and received by renewables producers.

The price on carbon that Garnaut and Sims want, their “carbon solution levy”, would be imposed on all emissions from Australian produced fossil fuel (whether those emissions occurred here or in the country that imported the fuel from us) and from any fossil fuel we imported.

Only about 100 businesses would pay the levy directly, though they would pass it on to their customers, of course. It would be levied at the rate of recent carbon emission permits in the European Union’s emissions trading scheme.

Imposing the levy on all our exports of fossil fuel, rather than just our own emissions, makes the scheme far bigger than the one Abbott scuttled in 2014. It would raise about $100 billion a year.

But it’s bigger to take account of the Europeans’ “carbon border adjustment mechanism” which, from 2026, will impose a tax on all fossil fuels imported from Australia that haven’t already been taxed.

Get it? If we don’t tax our fossil fuel exports, the Europeans or some other government will do it for us – and keep the proceeds.

What will we do with the proceeds of our levy? Most of them will go to a “superpower innovation scheme” that makes grants to support early investors in each of our new, green export industries. In this way it will lower the prices of carbon-free steel, aluminium and other products, helping them compete against the equivalent polluting products. The positive externality internalised.

Garnaut says we need to have the new levy introduced by 2031 at the latest. But the earlier it can be done, the more of the levy’s proceeds can be used to provide cost-of-living relief of, say $300 a year, to every household and business, as well as fully compensating for the levy’s effect on electricity prices.

Thank heavens some of our economists are working on smart ways to fix our problems while our politicians play political games.

Albo's economic report card: Must try harder on energy transition

Can Anthony Albanese’s government walk and chew gum at the same time? Should be able to, provided it stops trying to work both sides of the street.

As I wrote on Wednesday, the most urgent economic and political issue facing the government is the cost-of-living crisis.

But let’s get real. Everyone may be up in arms about the cost of living, but fixing it is standard stuff for the managers of the economy. We can be sure it will be fixed soon enough.

As we know from our own lives, we often let the urgent take priority over the more important, and that’s what this government has been doing.

What could be more important than easing my cost-of-living pain? All the different kinds of pain – the heatwaves, droughts, bushfires, floods and cyclones – that are coming our way unless the world does what’s needed to stop further global warming.

A big achievement at last year’s federal election was to get rid of a government of closet climate-change deniers only pretending to want to do something, and replace it with a government that did accept the scientists’ advice and did want to act on it.

But although Climate Change and Energy Minister Chris Bowen has been busy setting up the frameworks for reducing greenhouse gas emissions – fixing the “safeguard mechanism”, producing a hydrogen strategy and developing a critical minerals strategy, and, last month, announcing a scheme to underwrite the risk of investing in new renewable energy generation and storage – few new projects have begun or are in the offing.

That’s the trouble: actual progress is happening too slowly. Albanese’s game plan for this term seems to be softly, softly catchee monkey. Make sure you don’t offend any powerful interests, get comfortably re-elected and then think about getting tough.

There’s not enough sense of urgency. The longer it takes us to make the transition to renewable energy the more pain we’ll suffer in the process.

The Grattan Institute’s energy and climate change expert, Tony Wood, wants us to realise that this transition will be harder than anything we’ve had to achieve outside of wartime.

“We must manage the decline of the fossil fuel extractive sectors, transform every aspect of our energy and transport sectors, re-industrialise much of manufacturing, and find solutions to difficult problems in agriculture,” Wood says.

Note that the challenge comes in two parts. First, make the domestic shift from fossil fuels to renewables. Second – since the world will soon enough no longer want to buy our massive exports of coal and gas – find something else we can sell abroad.

Get it? If we don’t want to become a lot poorer, we’ve got to get weaving. Labor does get that to secure our future we must seize this limited-time opportunity to turn Australia into a renewable energy superpower.

Treasurer Jim Chalmers will tell you the government has already invested about $3 billion in the superpower project. But, again, we’re being too slow in getting on with it.

Nothing Australia can do by itself will halt climate change. That will take concerted, decisive action by all the big carbon-emitting nations. That will happen eventually, even if happens too late to prevent a lot more warming.

So, if we don’t mind being lasting losers from the eventual transition – the country that used to make a good living as an energy exporter – we can stay as laggards, waiting for America, China and Europe to do the heavy lifting.

If we want to stay winners, however, we have to get ahead of the others. We have to get to net-zero emissions before everyone else. We have to build a renewables industry so big it can meet our domestic needs, with at least as much energy to spare for export to countries less well-placed than us.

Most of our exported renewable energy would be “embodied” in green steel, green aluminium and other resources. This would be all to the good, allowing us to set up new manufacturing industries to further process our resources before selling them.

To achieve this unprecedented transformation will involve the government leading the way, funding research on how basic science can be commercialised, funding pilot projects, and reducing the risks for investors in renewables and storage.

This is challenging stuff for conventionally trained economists. They’re used to telling governments to let private firms pursue our “comparative advantage” by exploiting the nation’s “natural endowment”. They tell politicians never to try to “pick winners”.

But these are unprecedented times. Global warming has just torn up our comparative advantage in mining, rendering our natural endowment of huge remaining stocks of fossil fuels of little future value.

As Professor Ross Garnaut was the first to point out, however, in the new world where renewable energy is king, part of our natural endowment we formerly thought to be of little value is now our comparative advantage: relative to other countries, we have abundant supplies of sun and wind.

But waiting for private enterprise to turn our industrial structure on its head without government leadership is delusional. And, as we ought to have learnt by now, if you dissuade governments from picking winners, they end up backing losers: helping firms and workers who did well in the old world try to stop the clock.

That’s what’s wrong with the government’s softly, softly, all-things-to-all-persons approach to climate change. It’s working both sides of the street, taking an each-way bet: encouraging the move to renewables while retaining fossil fuel subsidies and allowing investment in new coal mines and gas projects.

It says a lot about the discombobulation of conventional economists that none of them beat the Australia Institute’s Dr Richard Denniss to pointing out the obvious: taking an each-way bet flies in the face of opportunity cost.

Allowing the established players to continue investing in fossil fuels deters them from investing in renewables. It also allows them to bid scarce skilled labour away from renewables and from rejigging the electricity grid. Sorry, the government must try harder.

'Planetary boundaries' set the limits of economic freedom

One of the most important developments in economics is something in which economists had no hand: the identification of the environmental limits which humans, busily producing and consuming, cross at their peril.

Earth has existed for about 4 billion years and humans have lived on Earth for about 200,000 years. For almost all of that time we were hunters and gatherers, but 10,000 to 12,000 years ago we settled down, to farm and create civilisation.

It’s probably no coincidence that, for about that time, Earth has enjoyed a stable climate, with no more ice ages nor period of great heat, in which palms grew in Antarctica. This is the geological epoch called the Holocene, in which we live – although it may be ruled that we’ve moved to the Anthropocene, a new epoch in which the human species has made major alterations to the planet.

In its modern form, economics can be dated to 1776, when Adam Smith published The Wealth of Nations. Beliefs about how the economy works were well-defined by the time Alfred Marshall published Principles of Economics in 1890.

The point is that all economic activity – all the efforts of humans to earn a living – both depends on the natural environment and adversely affects it. By 1900, there were only about 1.6 billion humans on the planet, not enough to do much damage.

If we wrecked some area, we could just move to somewhere that hadn’t been wrecked, while the first bit gradually recovered.

So, at the time conventional economics was established, it was perfectly sensible to assume that the environment’s role in economic activity could be taken for granted. It was just there and it always would be. It was, as economists say, a “free good”.

When, from the 1700s, we started burning fossil fuel – coal, oil and gas – for heat, light and energy, we had no reason to worry that one day it might run out. It certainly never occurred to us that this might end up having an effect on the climate.

It took many decades before scientists began telling us that all the things we were doing to improve our lives – cutting down forests, damming rivers, drilling for water, ploughing, fertilising crops, fishing with nets – were damaging the soil, causing erosion, killing species, lowering the water table, and damaging the environment in other ways.

However, in just the past century or so, the world’s population has gone from 1.6 billion to 8 billion. Every extra human does a bit more damage to the environment. But that’s not the main thing. The main thing that’s changed is our use of advances in technology to hugely increase our standard of living and, in the process, massively increase the damage we’re doing to the environment.

Which brings us to “planetary boundaries”. In 2009, the Swedish scientist Johan Rockstrom and a scientist from the Australian National University, the late Will Steffen, with many helpers, established a framework listing the key categories of environmental damage, and estimating the amount of damage that could be done to each before the risk increased that “the Earth system” could no longer recover.

A second update of these estimates, led by an American oceanographer based in Copenhagen, Katherine Richardson, was released last month. With the ANU’s Professor Xuemei Bai, Richardson has written an article explaining the planetary boundaries.

There are nine boundaries. Three of them cover what we take from the ecological system: loss of biodiversity (extinction of species), loss of fresh water (pumping too much water from rivers and aquifers) and land use (deforestation).

Something economists didn’t know – or didn’t realise affected them – is that the laws of physics say we can never truly get rid of anything that exists on Earth.

All we – or the ecosystem – can do is change the form of the thing. Water can evaporate, but it’s still up in the clouds, for instance. We can cut down a tree, but as it slowly sinks into the dirt, it releases the carbon dioxide it had previously taken up.

This means that all our economic activity leaves in its wake a lot of waste. Not just landfill, but in many other forms.

So, the remaining six boundaries concern the waste our activity greatly adds to what would have occurred naturally. They are: greenhouse gases which cause climate change, ocean acidification (carbon absorbed by the sea), emission of chemicals that deplete the Earth’s ozone layer, “novel entities” (synthetic chemicals such as plastics, DDT and concrete), aerosols, and nutrient overload (nitrogen and phosphorus from fertilisers that wash into rivers and the sea, causing algae blooms, killing fish and coral).

Crossing any of these boundaries doesn’t trigger immediate disaster. But it does mean we’ve moved from the safe zone into dangerous territory. And the nine boundaries are interrelated and interacting, in ways we don’t yet fully understand.

In 2009, the scientists found we’d already crossed three boundaries: biodiversity, climate change and nutrient overload. By the 2015 update, a fourth boundary had been crossed: land use.

And by this year’s update, only three boundaries hadn’t been crossed: ocean acidification (but only just), aerosol pollution, and stratospheric ozone depletion – where an international agreement banning CFCs is slowly reducing the ozone hole we created.

Richardson and Bai say we’re now well into the danger zone, “where we – as well as every other species – are now at risk”. “We are eating away at our own life support systems,” they say.

One thing to be said for economists is that, unlike some, they don’t try to tell scientists how to do their job. Very few economists dispute the scientists’ evidence that climate change has been caused by human activities.

It was economists who developed the best means to reduce carbon emissions – emission trading schemes – which other countries have adopted, but Australia rejected.

When our governments decide to act on the other planetary boundaries, it will be economists who work out the best way to do it.

We need economic growth to make us better off, right? Well, actually

For all our lives, worthies – our politicians, business people and economists – have assured us we need economic growth to make us better off. Almost everything I write assumes this to be true. But is it?

These days, there are more doubters than there used to be. Some people don’t believe that spending your life striving to own more stuff will make you happy. (Spoiler: they’re right.)

But a growing number of scientists tell us unending growth in the economy simply isn’t physically possible, and the more we keep growing the more we’ll damage the natural environment, to our great cost. Climate change is just the most glaring example of the damage we’re doing.

Historians remind us that our obsession with The Economy is relatively recent. It didn’t take hold until the middle of last century.

What we call “the economy” is all economic activity. It’s people getting up every morning, going out to earn a living, and then spending what they’ve earned. So it’s “getting and spending”, production and consumption. This is measured by gross domestic product – the value of all the goods and services produced during a period.

It was only when we started regularly measuring GDP in the mid-1950s that we began our obsession with whether it was growing and by how much. Or whether – God forfend – it was going backwards.

But these are just modern words and concepts. In truth, Australians have been preoccupied by what today we call economic growth since the day white people arrived. Their magic words were “settlement”, “progress” and “nation building”.

The recent arrivals saw a “new” nation where nothing had been done, but with huge potential for endless bush to be made to resemble the old country. They set about clearing the land, damming rivers, building houses, establishing farms and digging up minerals.

Why? To become more prosperous. They spurred themselves on with the belief they must “populate or perish” – be taken over by invading Asians.

So how do you achieve what we call economic growth? The easiest way is to grow the population. Have lots of kids and encourage (in those days, white-only) immigration. That gives you more people to work, but also more people needing to be fed, clothed, housed and entertained.

Bingo. A bigger economy. But while increasing the population makes the economy, GDP, bigger, it’s really only if the growth increases GDP per person that it can be claimed to make us better off, to have raised our material standard of living. And this doesn’t follow automatically.

The harder way to grow the economy is to increase the proportion of the population in paid employment, or to increase our investment in plant and equipment, and (well-chosen) public infrastructure. This does increase GDP per person.

But there’s another, more magical way to increase GDP per person. It’s to take the same quantity of resources – raw materials, labour and capital equipment – and use them to produce more output of goods and services than you did.

This is what people mean when they talk about increasing our “productivity”. It’s achieved, as economists keep repeating, by “working smarter, not working harder”.

How? By building a better educated and more skilled workforce, and by finding ways to make the organisation of factories and offices more efficient, but mainly by advances in technology that create better machines (and these days, computer programs) doing better tricks.

This is the bit scientists don’t get. When they hear the word “growth” they think of one thing: growth in humans’ exploitation of natural resources and all the damage we do to the environment in the process.

But that’s not what GDP measures. Economists know that most of the growth in GDP over the long term comes from increased productivity, not increased inputs of raw materials, labour and physical capital.

This means that, unless you believe there’s a limit to human ingenuity, it’s not true that continuing growth in GDP is impossible.

But when scientists say more clearly the kind of “growth” they’re referring to – growth in the use of natural resources and “ecosystem services” – it’s not possible to argue with the laws of physics.

While economists used to argue that the “limits to growth” weren’t as close at hand as some scientists had calculated, the possibility of the developing world enjoying the same profligate use of natural resources as the rich world is not credible. We expect the bottom 80 per cent to resign themselves to lives of relative poverty, while we in the top 20 per cent continue partying as though there’s no tomorrow.

So I accept that we and other rich countries will have to greatly constrain our use and abuse of the natural environment if the planet is to remain functional. A “circular economy” in which resources are so expensive that almost everything has to be repaired, reused and recycled? Sure.

But here’s the joke. It wouldn’t be the scientists who worked out how we could move to such an economy, it would be the economists.

Murray-Darling basin: farmers’ friends are helping them self-harm

Not only in America. If you think the United States has become dysfunctional and incapable of solving its pressing problems, I have three words to say to you: Murray-Darling Basin. Last week, federal Environment and Water Minister Tanya Plibersek announced a brave new plan to rescue the Murray-Darling rescue plan, which the feds, NSW and Victoria had agreed to give up as all too hard.

Since the issue’s unlikely to be front of mind, let me tell this sorry story from the beginning. I’ll do so with much help from Professor Jamie Pittock of the Australian National University, an environmental scientist who’s been studying it for most of his career. (His many articles are on the universities’ The Conversation website.)

The Murray-Darling Basin covers about a seventh of Australia’s land mass: most of NSW, all the Australian Capital Territory, much of Victoria, and parts of Queensland and South Australia. It covers the Murray and Darling rivers, plus all their many tributaries, including the Murrumbidgee.

You could call it the nation’s biggest food bowl, underpinning the livelihoods of 2.6 million people and producing food and fibres worth more than $24 billion a year. Vast amounts of water are extracted from the rivers to supply about 3 million people, including those in Adelaide, but particularly for irrigating farms.

It’s also a living ecosystem that depends on interconnected natural resources. About 5 per cent of the basin consists of floodplain forests, lakes, rivers and other wetland habitats. Like all our rivers, the Murray-Darling is subject to recurring droughts and flooding.

Over the past century, however, the extraction of water, especially for irrigation, has reduced water flows to the point where the system can no longer recover from these extreme events.

Over the past decade, millions of fish have perished in mass die-offs, toxic algae have bloomed, wildlife and waterbird numbers have declined and wetlands have dried up.

Efforts to reverse the river system’s decline began with big-spending announcements by John Howard and his environment minister Malcolm Turnbull before the election they lost in 2007. It took five years before Julia Gillard and Tony Burke reached agreement with the basin states on a plan to restore the river system.

Under the then $13 billion plan, 3200 billion litres a year would be returned to the rivers, largely by buying back water entitlements from willing farmers. But the plan’s been modified several times and in 2015 the feds decided to cease buying back entitlements. Both the NSW and Victorian governments had been persuaded by their farmers to oppose buybacks.

NSW and Victoria have not delivered on their promise to reach agreements with riverside landowners to allow bought-back water to spill out of river channels onto floodplain wetlands. Another problem has been farmers drawing more water than their entitlement.

The buybacks have stalled at 2100 billion litres a year, even though the planned 3200 billion litres is probably too little to counter the evaporation caused by global warming. The plan had been due to be completed by June next year, with a new agreement in 2026.

But, in the 2022 election campaign, Anthony Albanese promised to revive the scheme and buy back the remaining water needed to meet the 3200 billion-litre target, and last week Plibersek announced a new deal with all the states, bar Victoria.

She agreed to another two or three years to deliver the remaining water, more options to deliver it, more funding to pay for it and more accountability by the feds and other governments to deliver on their obligations.

But she will need the support of the Greens and independents to get the new deal through the Senate. The opposition won’t support the resumption of buybacks, whereas the Greens don’t like the extra time to be taken.

Of course, even if the legislation goes through, there’s no guarantee the various governments will do what they’ve committed to. The feds are doing what the feds always have to do to get the states’ co-operation – offer them more money – but Victoria and NSW will always be tempted to keep their own farmers and river towns on side, which remain strongly opposed to buybacks.

How can it be so hard to ensure the continued survival of such an important river system? To say that, without remedial action, the rivers could shrink to a chain of billabongs is no great exaggeration. That might not happen for 50 years but, the way climate change seems to be accelerating, it could be a lot sooner.

You’d think the people who’d see this most clearly were those who stand to lose most as the rivers continue to shrivel. But, no, myopia prevails.

Take some pain now to avoid catastrophe later? No way! You can keep all the city-slickers’ tax money you want to pay us to help us adjust. We’re betting it will never happen. In any case, I’ll be dead by then.

And politicians who will take the votes of people who’d prefer to self-destruct aren’t hard to find. Reminds me of the way things are in the Land of the Free.

What a future: impossible climate, a life of renting and a crappy job

The older I get, the more I worry about the nightmare we oldies are leaving for our children and grandchildren. The obvious, in-your-face problem is climate change, but other difficulties are everywhere you look.

Now the northern hemisphere has been introduced to the joys of bushfires and heatwaves with, I imagine, a cleanser of flooding to come, global warming has become global boiling. Climate change is now — and will get a lot worse even before we oldies have popped off.

We wasted decades worrying about the economic cost of doing something about climate change, now we’re facing the daunting economic costs of not having done anything about climate change.

We’ve exchanged a government of closet climate-change deniers for a government that knows what it should do, but is dragging its feet under the influence of two powerful unions representing the interests of a relative handful of mine workers who don’t want to look for jobs elsewhere.

Then there’s the way the older generation of home owners has allowed the lure of ever-rising house prices to permit successive governments to turn housing into an inheritance lottery.

Australia is dividing into two distant tribes: the owners and the renters. If you have the good fortune to be born to home-owning parents (perhaps with an investment property or two on the side), the Bank of Mum and Dad will ensure you too eventually become a home owner, able to pass your good fortune on to your own kids.

But pick renters as your parents — or have too many siblings — and you, like them, will be a life-long renter. As will your kids.

And, naturally, governments couldn’t possibly oblige landlords to give their tenants more security and better maintenance without the landlords giving up and leaving thousands homeless on the streets. (Yeah, sure.)

HECS HELP debt is adding to the difficulty of making it onto the home ownership merry-go-round. The scheme was designed to have people who benefit from a university education contribute towards its cost without discouraging kids from poor families from seeking to better themselves.

But incessant tinkering by successive governments has turned HECS into a millstone.

And all that’s before you get to the gig economy, better thought of as the rise of insecure employment. The security of having a full-time, permanent job is something the older generation has been able to take for granted. Not so the youngsters.

In the latest surge of inflation, businesses haven’t hesitated to pass on to customers the higher cost of imported inputs, often seeming to add a bit extra for luck.

But in the decade or two before then, price rises were modest, sometimes even falling below 2 per cent a year, despite healthy growth in profits.

One way that businesses kept prices low was to find new ways of holding down labour costs. With the gig economy, people seeking to earn a living from digital sites are treated as contractors rather than employees.

They thus get no guaranteed work, no paid sick or holiday leave, no workers’ compensation cover and no employer contributions to their superannuation. Their work is precarious.

But that’s just the bit that gets the publicity. Less talked about are the various devices businesses have used to minimise labour costs, shift risks onto workers, and weaken the legal link with their workers by using labour-hire companies, setting up franchise arrangements and disposable subsidiaries.

Above all, workers have been hired as casuals. Casual employment is meant for cases where work is intermittent, short-term or unpredictable. But these days many casuals work full-time, most work the same hours from week to week, more than half can’t choose the days on which they work, and most have been with their employer for more than a year.

Casual workers get no sick or holiday pay, meaning if they’re too sick to work they earn no income. If they take a break, they have to live on their savings.

In principle, they get a 25 per cent loading instead. But get this: as best we can tell from official statistics, less than half actually receive it.

And because they’re casuals, they get no job security. Permanent employees can’t be sacked without due cause. If they’re laid off, they get redundancy money. Casuals don’t have to be sacked and don’t get redundancy. They just don’t get rostered on.

Some companies avoid union wage rates and conditions by using workers actually employed by labour-hire companies.

Last week, workplace relations minister Tony Burke announced further details of the government’s plan to make it easier for casual workers to apply to become permanent. Earlier he’d announced plans to require labour-hire workers to be paid the same as the regular employees doing the same work beside them.

Naturally, the employer groups cried that this would “increase business costs and risks” – which I take as a tacit admission that causal workers have been underpaid.

It’s not much, but it’s a step towards giving the younger generation a better future.

Climate change will hurt, but we can still be the Lucky Country

What are we in for with climate change? How will it change the environment, the way we live and the way we earn our living? Is it all bad news for the economy, or is there some upside? And, by the way, how much is it costing us as taxpayers?

The previous federal government didn’t want to think about these questions, much less talk about them. You could read the budget papers each year and hardly find a mention.

But all that’s changed with the change of government. So, no surprise that last week’s budget has a lot in it about climate change.

In various parts of the budget papers, the Albanese government acknowledges that, with the globe already having warmed by an average of 1.1 degrees above pre-industrial levels, global warming will continue changing our weather (short-term changes) and climate (longer-term patterns) for the rest of this century.

It will endanger more species and reduce biodiversity. It will adversely affect human health, with more days of extreme heat leading to more deaths of old people.

The productivity of labour and the number of hours worked are expected to decline as temperatures increase, particularly for people who work outdoors in agriculture, construction and some manufacturing.

Treasury expects farming yields to decline, and I expect that, over time, the production of different crops and the grazing of animals will migrate to the parts of Australia where the climate is less unsuitable.

Speaking of migration, you’d expect our population to grow faster where it’s relatively cooler, with fewer people wanting to live where it’s even hotter than it is today.

And that’s before you get to people – refugees, even – moving between countries in response to rising sea levels. Starting, in our case, with people from the islands of the South Pacific.

Treasury says the increased frequency and severity of natural disasters will also lead to reductions in the production of goods and services through disruptions to economic activity, and to the destruction of private property and road, bridge and rail infrastructure.

It shows that the value of insurance claims has steadily increased over the past decade, with temporary peaks caused by the floods in Queensland and NSW in March 2013, Cyclone Debbie and Sydney hailstorms in March 2017, then bushfires and hailstorms in NSW and the ACT in the last quarter of 2019 and the first quarter of 2020.

So far, the greatest insurance claims – $6 billion-worth – were from the floods in south-east Queensland and NSW in the March quarter last year. Then there were (less costly) floods in NSW, Victoria and Tasmania late last year.

Treasury says our economy will be reshaped by both the physical impacts of climate change and by the efforts of the more than 150 countries that have now signed up to the target of net-zero emissions by 2050. What they do will affect us, plus what we ourselves do.

Australia is one of world’s biggest exporters of fossil fuels, so we can expect our exports of coal and gas to decline steadily over the next decade or two, as our overseas customers reduce their own greenhouse gas emissions from burning the dirty fuel they bought from us.

Of course, not all of them will have their own plentiful sources of renewable energy. They’ll have to import it from somewhere, just as they’ve had to import our fossil fuels.

Which gives us an opening. As our great apostle of smart climate change, economics Professor Ross Garnaut, was first to realise, Australia’s huge expanse, full of sun and wind, means we’ll be able to produce far more renewable energy than we need for our own use. And do it cheaply.

Gosh, what good luck we’ve got. Turns out the move to renewables will give us a “comparative advantage” in international trade we didn’t know we had. All we’ve got to do is play our cards right and get in quick before other, less well-endowed countries sign up our potential customers.

The former government wasn’t interested but, as the budget papers make clear, the Albanese government is. The “net-zero transformation”, which represents one of the most significant shifts in the industrial structure of the economy since the Industrial Revolution, “holds major opportunities for Australia, given our endowment of renewable energy sources and our large reserves of many critical minerals,” the papers say.

There is a problem, however. As yet, there isn’t an economic way to ship raw clean electricity and green hydrogen across the sea to other countries.

But this could be a good thing. We can “embed” our renewable energy in our mineral exports by further processing our iron ore into green steel, and our bauxite into green aluminium, before we export them.

Whereas in the old, fossil fuel world the further processing of our minerals before export wasn’t “economic” (profitable) – in the renewables world it could well be economic.

Get it? We could give our declining manufacturing industry a whole new lease on life. What’s more, it would make economic sense to do the further processing out in the regions, close to the solar and wind farms generating the clean electricity.

Implementing such a transformation would require huge capital investment and risk-taking, the early part of which would have to come from the government.

So, yes, climate change – both the bad bits and the good bits – will come at a great cost to the budget, and thus to taxpayers.

The budget papers reveal the Albanese government planning to spend an extra $25 billion on new climate-related programs over several years in its first budget last October, and now a further $5 billion in last week’s budget. Don’t think that will be the last of it.

So, get ready to hand over more in taxes as the government seeks both to ameliorate the costs of climate change and turn the world’s energy transformation to our advantage.

At least now we’ve got a government willing to get off its backside.

Climate choice: cling to past glories or strive for prosperous future

The big question facing our political leaders is: are we content to allow climate change to turn us from winners into losers, or do we have the courage and foresight to transform our mining, energy and manufacturing industries into clean energy winners?

For most rich countries, playing their part in limiting global climate change is simply about switching from fossil fuels to renewable energy. For us, however, there’s a double challenge: as one of the world’s biggest exporters of fossil fuels, what do we do for an encore?

When it comes to deciding how we can earn a decent living, economists are always telling politicians to pursue our “comparative advantage” – concentrate on doing what we’re better at than other people, and they want to buy from us; then use the proceeds to buy from them what they’re better at than we are.

Turns out our “natural endowment” makes us better at farming and mining. Climate change will be bad for farming (not that the world will stop wanting to eat), and the only future for fossil fuel exports is down and out. It may take a decade or two to reach zero, but there’ll be no growth from now on.

Most economists have little to say about what you do when your natural endowment becomes a stranded asset and our comparative advantage evaporates. Except for Professor Ross Garnaut, who was the first to realise that nature has also endowed us with a bigger share of sun and wind.

If we tried hard enough and were quick enough, we could not only produce all the renewable energy we need for our own use, but find ways to export it to less well-endowed countries, probably embodied in green steel and aluminium.

This, of course, involves innovation and risks. We’re talking about technological advances that haven’t yet been shown to work, let alone commercialised. Doing things that have never been done before.

When it comes to technology, Australia is used to following the leader, not being the leader. Until now, this has been sensible for a smaller economy like ours. But we’re facing the impending loss of our biggest export earner. If we can’t find something just as big to sell, we’ll see our standard of living rapidly declining.

The threat we face isn’t quite existential. We’ll still be alive, just a lot poorer – and kicking ourselves for not seeing it coming and doing something about it.

The solution’s in two parts. First, the federal government must make clear to the coal and gas industries, the premiers, the mining unions and the affected regions that there’ll be no further support or encouragement for anyone pretending they haven’t seen the writing on the wall. Anyone trying to stop the clock and keep living in the past.

There’ll be plenty of support and encouragement, but only for those industries, workers and regions needing help to move from the old world to the new. As part of this, the government must do what now even the UN secretary-general says every country must do: end subsidies of fossil fuels and use the money to assist the move to renewables and green production.

Help coal miners relocate or retrain – whatever. Promise that, wherever it made sense, the new renewable and green industries would be set up near the old mines.

Ideally, the policy of ending the old and moving to the new should be bipartisan. No opposition should take the low road of courting the votes of those preferring to keep their head in the sand.

But if that’s too much to ask of a two-party duopoly, Anthony Albanese and the Labor premiers should take their lives in their hands and overcome their life-long fear of what the other side will say when you put the national interest first.

Second, pick winners. Econocrats spend their lives telling governments not to do that – not to subsidise new industries you hope will become profitable.

Trouble is, politicians being politicians, you can be sure they’ll be putting taxpayers’ money on some horse in the race. And if they’re not trying to pick winners, they’ll be doing what they’re doing now: backing losers. Which would you prefer?

More importantly, it’s a neoliberal delusion that new industries just spring up as profit-seeking entrepreneurs seek new ways to make their fortunes. Doing something never done before is high risk. The chance of failure is high. Banks won’t lend to you.

We don’t stand a chance of becoming a green superpower without a lot of government underwriting with, inevitably, some big losses. But I can think of many worse ways of wasting taxpayers’ money.

Voters turn from the big parties, increasing political competition

John Howard is right to describe the NSW election result as a “conventional change of government”. An old and disfigured government was tossed out and the other side given a go. It’s common when a government’s been in power for a decade or more. But don’t let this convince you nothing’s changed about the way we vote.

What’s happening is that the longstanding two-party system of government is breaking down before our eyes. Years of bad behaviour by the Coalition and Labor are leading more people to vote for minor parties and independents.

This means it’s become rare for any government, state or federal, to be elected with a big majority. Majorities now tend to be narrow, and minority governments are common, particularly at state level.

The big two are always telling us a “hung parliament” would be a terrible thing, causing “chaos and confusion”. Not true. They say this because it would be a terrible thing for them, requiring them to do deals with people they hate, to get the numbers to govern.

The “crossbenchers” usually drive a hard bargain. NSW’s four-year, fixed-date elections were forced on Liberal premier Nick Greiner in 1991 by three independents. Julia Gillard’s short-lived carbon tax was forced on her by the Greens, when she fell short of a majority in 2010.

So weaker governments are bad for the major parties, but good for democracy and voters, who get more to choose from.

Why is any of this the business of an economics writer? Because the nature of competition between a few big players in a market – “oligopoly” – is a subject economists study. And two-party government has a lot in common with markets dominated by two huge companies – duopoly.

But first, a closer look at the latest election. The “landslide” to Labor is looking a fair bit less than it looked on Saturday night. Chris Minns hasn’t yet secured a majority, and if he does, it will be narrow. Why? Because so many people are voting for minor parties and independents. At this stage in the counting, 28 per cent of voters spurned the big two. This compares with almost 32 per cent at the federal election last May, where the big swing away from the Liberals gave Labor just a narrow majority.

In NSW, the Greens look to have retained their three seats in the lower house, with independents looking sure of eight seats, and probably more. One of the new independents was backed by teal money.

An American economist named Harold Hotelling is famous for talking about a beach with two ice-cream sellers. From the swimmers’ perspective, the best place for them would be one at the quarter-mark and the other at the three-quarter mark. This would minimise the distance anyone had to walk to get a cone.

But Hotelling figured that the two would end up back-to-back at the centre of the beach. Why? Because that was the way each could ensure the other got no more than half the “market share”.

The social psychologist Hugh Mackay says that the key to competition is to focus on the customer, not your competitor. That’s just what oligopolists and our political duopolists don’t do.

If there’s one thing most people don’t understand about politics it’s the way each big party obsesses about what the other side’s doing, and how it will react to what they do.

It was this that caused Anthony Albanese to go to last year’s election promising to do nothing that could offend anyone much. Promise to make needed but controversial changes and the other side launches a scare campaign. It’s only when politicians tell us how bad the other side’s policies would be that we’re tempted to believe them.

The two sides are always trying to “wedge” each other by announcing a bad but popular policy and hoping the other side will be silly enough to oppose it.

Trouble is, they rarely fall for it. They sidestep the wedge by supporting the policy. Which means both sides end up agreeing to do bad things. This is why Albanese agreed to the AUKUS pact sight unseen and, earlier, to stick with the stage three tax cut that’s biased against Labor voters.

This is where the minor parties come in, particularly those sharing the balance of power in the Senate. They can use their power to stop, or at least tone down, the bad policies the government of the day foolishly locked itself into.

Consider this. Last week Climate Change Minister Chris Bowen loudly vowed not to negotiate with the Greens over his “safeguard mechanism”. But by Monday, wiser heads had prevailed, and a deal was done, making the mechanism much more effective.

The big two each offer voters a policy package-deal not very different to the other one’s. Whichever package you pick will include policies you don’t like. But the minor party and independent “new entrants” to the political market give consumers a wider choice by forcing the big guys to “unbundle” their packages.

Sounds more like democracy’s supposed to be.

Labor is just pretending to be tough on climate change

Labor talks the talk, but doesn’t walk the walk. Last week’s “final warning” from the Intergovernmental Panel on Climate Change – and the Albanese government’s refusal to be moved by it – should be a game-changer in our assessment of Labor’s willingness to do what must be done.

The IPCC’s message – driven home by UN Secretary-General Antonio Guterres – was that we’re almost out of time to avoid much of the worst climate change. Whatever plans we had to reduce greenhouse gas emissions, we must step them up, and speed them up.

Regarding last year’s federal election, the message is that Labor’s plan is complacent and compromised, and the Greens and teals were right to demand much tougher, faster action.

But not only did Climate Change Minister Chris Bowen show no sign of getting the UN’s message, he announced his refusal to negotiate with the Greens to make improvements to his “safeguard mechanism” legislation.

You need to know that Albanese Labor hates the Greens more than it hates the Liberals. Bowen could have decided to use the need to win the Greens’ support for his bill in the Senate as cover for making the bill stronger than Labor promised in the election campaign.

Instead, he decided to put the interests of our grandchildren second to this fabulous chance to “wedge” the Greens. They could either vote for Labor’s bill as is, or they could join the Coalition in voting it down – just as they did when they voted down Kevin Rudd’s carbon pollution reduction scheme in 2009.

This would leave the government with no means of achieving its target of reducing emissions by 43 per cent by 2030. And, Bowen bellowed in the House, that would be all the Greens’ fault. (It doesn’t seem to have occurred to Bowen and his boss that if they go to the 2025 election having done nothing to fight climate change, blaming it all on the Greens won’t be a good enough excuse.)

But last week showed that the problem with Labor isn’t just its political cynicism and game-playing. Until last week, it was possible to see the Greens’ demand that no new coal and gas projects be approved as the kind of over the top zealotry you’d expect from those crazies. And, as it happens, the teals.

This is what Guterres said last week in welcoming the IPCC’s final warning. “The climate time-bomb is ticking.” We do have time to defuse it, “but it will take a quantum leap in climate action”.

We must “massively fast-track climate efforts by every country and every sector and on every timeframe”.

He was proposing an “acceleration agenda” with, specifically, “no new coal and the phasing out of [existing] coal by 2030 in [the rich] countries and 2040 in all other countries. Ending all international public and private funding of coal” and “ceasing all licensing or funding of new oil and gas”, as already proposed by the International Energy Agency and “stopping any expansion of existing oil and gas reserves. Shifting subsidies from fossil fuels to a just energy transition”.

That’s not some crazy greenie, that’s the UN secretary-general.

Yet, the very same week, Bowen had the temerity to claim that stopping new projects would be “irresponsible”. That’s now the opposite of the truth.

It’s not by chance that Bowen is the Minister for Climate Change and Energy. It’s not just the Coalition that’s in bed with the fossil fuel industry; Labor is too. Labor just does a better job of covering it up.

Federal Labor will not commit to stopping the proposed 116 new coal and gas projects. When Albanese went to India recently, he took fossil fuel people with him, so they could sell more coal.

The many state Labor governments are committed to approving new projects. That’s another thing that happened last week: on election night in NSW, the new state Labor minister made it clear the Minns government would not be stopping new projects.

Labor wants to be in bed both with those who want real action on climate change and the fossil fuel industries. Someone famous once said, “No one can serve two masters”. One of his saintly followers once prayed, “Lord, make me pure – but not yet”. That’s Labor.

Which brings us to the safeguard mechanism Labor is refusing to improve. Bowen has conned some conservation groups into supporting his plan because, though it’s not perfect, “something is better than nothing” and “it’s a start: get it passed, and seek to improve it later”.

Come in, sucker. What last week shows is that there isn’t time to improve it later. Labor has tried to wedge the Coalition by building its reduction scheme on the base of Tony Abbott’s safeguard mechanism, which was largely for show and did nothing to reduce emissions.

But if Labor is taking over an ineffective scheme from the secret climate change deniers, now’s the time to make it effective, not later. The fact is, the safeguard mechanism is riddled with loopholes.

The first loophole is our fossil fuel exports. Under the UN’s rules, a country is responsible for the emissions that occur on its own territory. Bowen’s renovations would, in theory, reduce the local emissions of our biggest polluting industries. It would also reduce the local emissions from any big new coal and gas export projects.

But it would permit other countries to maintain or increase their emissions from fossil fuels they bought from us. The UN will blame them for those emissions, not us. Great loophole, eh?

Trouble is, greenhouse gas is a global problem, not a local one. And we’re one of the biggest exporters of fossil fuels in the world. We export far more future emissions than we emit ourselves. So, what we do at home doesn’t add to climate change nearly as much as what others do with the coal and gas we sell them.

Bowen’s version of Abbott’s safeguard mechanism has a second major loophole. The big polluters must either progressively reduce their emissions according to the government’s phase-down, or buy the equivalent carbon credit offsets from someone else – often a farmer who’s planted more trees.

First problem is that there’ll be no limit to the extent that a polluter can resort to carbon credits. So it’s possible they’ll continue pumping out greenhouse gases, and mainly just buy credits from elsewhere.

This could lead to far more reliance on credits than the UN agreements envisaged. Credits were supposed to be used mainly by industries, such as cement and steelmaking, that find reducing emissions exceptionally difficult.

The other problem is that a lot of the carbon credit offsets are dodgy – they’re not like for like as a substitute for genuine emission reductions.

These were the main loopholes in Bowen’s rejigged safeguards mechanism that the Greens, the teals and Senator David Pocock were hoping to see improved by negotiations with Labor.

They make it debatable whether, in this case, something is better than nothing. One advantage of voting down Bowen’s bill would be to stop Labor pretending it had done something meaningful about climate change while actually prolonging the future of our fossil fuel industries.

Labor's new plan to reduce our emissions is riddled with loopholes

While I was on holiday, I noticed a tweet that left me in no doubt about the subject of my first column back. It said: “I genuinely think the next generation will not forgive us for what we have done to them and the world they will have to live in.”

I, too, fear they won’t. I don’t know whether our political leaders ever think such thoughts, but it fills me with dread. Maybe the pollies think what I reluctantly think: With any luck, I’ll be dead before the next generation realises the full extent of the hell our selfish short-sightedness has left them in.

But the climate seems to be deteriorating so rapidly I’m not sure I’ll get off that easily. I love my five grandkids, but I’m not looking forward to the day they’re old enough to quiz me on “what I did in the war”. What was I saying and doing while our leaders were going for decades kicking the problem down the road as the easiest way to get re-elected?

“Well, I was very busy writing about the shocking cost of living – oh, and rising interest rates.” Really? Is that the best excuse you can offer, Grandad?

We elected a bloke called Albo who promised to try a lot harder than his predecessors to reduce our emissions of greenhouse gases. He said he’d cut them by 43 per cent by 2030. He was quick to put that target into law, and his people worked through the Christmas holidays to outline the “safeguard mechanism” he’d use as his main measure to achieve the reduction.

While the rest of us were at the beach, Climate Change Minister Chris Bowen announced a few weeks ago that Australia’s 215 biggest industrial polluters – running coal mines, gas plants, smelters and steelworks – will have their emissions capped, with the caps lowered progressively by 30 per cent come 2030.

Businesses whose emissions exceed their cap will face heavy fines. To the extent they can’t use cleaner production processes to reduce their emissions, they’ll be allowed to buy “carbon credits” from other heavy polluters who’ve been able to reduce their emissions by more than required, or from farmers who’ve planted more trees.

Trouble is, it wasn’t long before the experts started pointing to all the holes in the scheme. For a start, the combined emissions of these biggest polluters account for only 28 per cent of Australia’s total emissions.

For another thing, the notion that, as well as reducing the carbon we’re adding to the atmosphere, we should find ways to remove some of the carbon that’s already there is a good one in principle, but riddled with practical problems.

Whereas the carbon we emit may stay in the atmosphere for 100 years or more, the carbon sequestered by a new tree will start returning to the atmosphere as soon as it dies or is cut down. It’s hard to measure the amount of carbon that tree-growing and other agricultural activities remove, which makes such schemes particularly easy to rort.

In his recent report into expert criticism of our carbon credits scheme, Professor Ian Chubb sat on the fence. While judging the scheme to be “well designed”, he identified various dubious practices that should be outlawed. And he stressed that big polluters must not rely on buying carbon credits to the extent that they’re able to avoid reducing their emissions in absolute terms.

A further weakness in the government’s scheme comes from its refusal to prohibit any new coal mines and gas plants, despite the International Energy Agency and other international agencies saying the world won’t have any chance of avoiding dangerous climate change if it’s relying on new gas or coal projects.

So, the scheme involves leaning on our existing 215 biggest polluters to reduce their emissions by 30 per cent, while allowing a bunch of new big emitters to set up, provided they then start cutting those emissions back.

Really? This is how we’re going to cut our total emissions by 2030? Seriously?

Last year a reader rebuked me for failing to make it clear that nothing Australia does to reduce its own emissions can, by itself, have any effect on our climate. Why not? Because climate is global, and we’re not big enough to have a significant effect on total world emissions.

The best we can do is set a good example, then pressure the bigger boys to do likewise. So far, we’ve been setting them a bad example.

It’s the global scale of the problem that makes our efforts actually to increase our exports of coal and gas so irresponsible – and, to our offspring, unforgivable. We’re the world’s third-largest exporter of fossil fuels, after Saudi Arabia and Russia.

Australia’s emissions within our borders are dwarfed by the emissions from the coal and gas we export. But never mind about that. Let’s just extract a few more shekels before the balloon goes up.

RBA warning: our supply-side problems have only just begun

In one of his last speeches for the year, Reserve Bank governor Dr Philip Lowe has issued a sobering warning. Even when we’ve got on top of the present inflation outbreak, the disruptions to supply we’ve struggled with this year are likely to be a recurring problem in the years ahead.

Economists think of the economy as having two sides. The supply side refers to our production of goods and services, whereas the demand side refers to our spending on those goods and services, partly for investment in new production capacity, but mainly for consumption by households.

Lowe notes that, until inflation raised its ugly head, the world had enjoyed about three decades in which there were few major “shocks” (sudden big disruptions) to the continuing production and supply of goods and services.

When something happens that disrupts supply, so that it can’t keep up with demand, prices jump – as we’ve seen this year with disruptions caused by the pandemic and its lockdowns, and with Russia’s attack on Ukraine.

What changes occurred over the three decades were mainly favourable: they involved increased supply of manufactured goods, in particular, which put gentle downward pressure on prices.

This made life easier for the world’s central banks. With the supply side behaving itself, they were able to keep their economies growing fairly steadily by using interest rates to manage demand. Put rates up to restrain spending and inflation; put rates down to encourage spending and employment.

The central banks were looking good because the one tool they have for influencing the economy – interest rates – was good for managing demand. Trouble is – and as we saw this year – managing demand is the only thing central banks and their interest rates can do.

When prices jump because of disruptions to supply, there’s nothing they can do to fix those disruptions and get supply back to keeping up with demand. All they can do is strangle demand until prices come down.

So, what’s got Lowe worried is his realisation that a lot of the problems headed our way will be shocks to supply.

“Looking forward, the supply side looks more challenging than it has been for many years” and is likely to have a bigger effect on inflation, making it jump more often.

Lowe sees four factors leading to more supply shocks. The first is “the reversal of globalisation”.

Over recent decades, international trade increased significantly relative to the size of the global economy, he says.

Production became increasingly integrated across borders, and this lowered costs and made supply very flexible. Australia was among the major beneficiaries of this.

Now, however, international trade is no longer growing faster than the global economy. “Trading blocs are emerging and there is a step back from closer integration,” he says. “Unfortunately, today barriers to trade and investment are more likely to be increased than removed.”

This will inevitably affect both the rise in standards of living and the prices of goods and services in global markets.

The second factor affecting the supply side is demographics. Until relatively recently, the working-age population of the advanced economies was steadily increasing. This was also true for China and Eastern Europe – both of which were being integrated into the global economy.

And the participation of women in the paid labour force was also rising rapidly. “The result was a substantial increase in the number of workers engaged in the global economy, and advances in technology made it easier to tap into this global labour force,” Lowe says.

So, there was a great increase in global supply. But this trend has turned and the working-age population is now declining, with the decline projected to accelerate. The proportion of the population who are either too young or too old to work is rising, meaning the supply of workers available to meet the demand for goods and services has diminished.

The third factor affecting the supply side is climate change. Over the past 20 years, the number of major floods across the world has doubled and the frequency of heatwaves and droughts has also increased.

This will keep getting worse.These extreme weather events disrupt production and so affect prices – as we know all too well in Australia. But as well as lifting fruit and vegetable prices (and meat prices after droughts break and herd rebuilding begins), extreme weather can disrupt mining production and transport and distribution.

The fourth factor affecting the supply side is related: the transition from fossil fuels to renewables. This involves junking our investment in coal mines, gas plants and power stations, and new investment in solar farms, wind farms, batteries and rooftop solar, as well as extensively rejigging the electricity network.

It’s not just that the required new capital investment will be huge, but that the transition from the old system to the new won’t happen without disruptions.

So, energy prices will be higher (to pay for the new capital investment) and more volatile when fossil-fuel supply stops before renewables supply is ready to fill the gap.

Lowe foresees the inflation rate becoming more unstable through two channels. First, shocks to supply that cause large and rapid changes in prices.

Second, the global supply curve becoming less “elastic” (less able to respond to increases in demand by quickly increasing supply) than it has been in the past decade.

Lowe says bravely that none of these developments would undermine the central banks’ ability to achieve their inflation target “on average” - that is, over a few years – though they would make the bankers’ job more complicated.

Well, maybe. As he reminds us, adverse supply shocks can have conflicting effects, increasing inflation while reducing output and employment. The Reserve can’t increase interest rates and reduce them at the same time.

As Lowe further observes, supply shocks “also have implications for other areas of economic policy”. Yes, competition policy, for instance.

My conclusion is that managing the economy can no longer be left largely to the central bankers.

Treasury's advice now back in favour with the government

The Coalition’s practice of sacking a bunch of government department heads whenever it gets back to office is clearly calculated to discourage bureaucrats from giving frank advice. Fortunately for us, the Albanese government is not as arrogant.

In my experience, weak managers surround themselves with yes-persons, so their brains – and, as they see it, their authority – aren’t challenged.

Strong managers want frank advice from their experts, so they’re less likely to stuff up. They’re confident of their ability to sift through conflicting advice and pick the best way forward.

This Liberal policy of frightening bureaucrats into keeping their opinions to themselves began when they returned to power in 1996 under John Howard. It was repeated when Tony Abbott got back in 2013, sacking then Treasury secretary Dr Martin Parkinson and various other Treasury-related department heads (narrowly missing Treasury’s incumbent, Dr Steven Kennedy).

Their crime, it seemed, was that they actually believed in the Rudd-Gillard government’s policy of using an emissions trading scheme to limit carbon emissions. Guilty as charged. Like almost all economists, Treasury accepted the scientists’ advice on the science, and believed the best tools for fighting climate change were economic instruments such as “putting a price on carbon”. Labor’s Department of Climate Change was staffed manly by Treasury people.

But the Libs’ peak disdain for the public service came under Scott Morrison who, upon attaining the top job, told the bureaucrats he wanted no advice from them, just diligent implementation of the policy decisions made by Cabinet.

What gave this bunch of not-so-super men (and the odd woman) the arrogance to believe they could govern wisely without the bureaucrats’ policy advice? Mainly, their ability to fall back on the small army of taxpayer-funded, but unaccountable ministerial staffers, mainly youngsters with political ambitions and the willingness to interpose themselves between the minister and the department.

These young punks, who think they outrank the most senior public servants, are generally big on politics, but weak on policy. Which, you’d have to say, was the Coalition cabinet’s “revealed preference”.

The apotheosis of this decadence was revealed in evidence to the robo-debt royal commission last week. Advice sought from an outside law firm, which found that the government’s cost-cutting scheme was unlawful, was paid for but not passed up the line to the minister – presumably because the bureaucrats judged it would not be welcome.

But in a little-noticed part of a recent speech by Treasurer Jim Chalmers, he left no doubt that, under Labor, Treasury’s advice would be sought, and used to improve the government’s decisions. What’s more, Treasury’s ability to convey its views to the public would be enhanced.

Chalmers noted that, even after the government had dealt with the inflation challenge, “we will have to manage a budget weighed down by persistent structural spending pressures”. Doing this required new thinking and deeper thinking, he said.

“It requires us rebuilding the evidence base for policymaking. Because, to get better, more-forward-looking economic policies, we need better, more-forward-looking policy foundations.”

Chalmers revealed six ways in which he will be “rebuilding the evidence base for policymaking”. One was “putting Treasury back at the centre of climate modelling again”, to build on “the new approach to climate risks, costs and opportunities” revealed in last month’s budget papers.

Second, Treasury’s annual statement on “tax expenditures” would be made “more accessible, more useful analysis of what tax concessions are costing the budget” and their effect on the distribution of income between high and low earners.

Economists have long believed that such “tax expenditures” are equivalent to actual government spending in their effect on the budget balance, and should be subject to just as much critical reassessment as actual spending.

But the Libs didn’t agree. Since taxes are evil, anything you do to reduce them must be a good thing, even if the concessions go to some (usually higher-earning) taxpayers and not others. They sought to play down the tax expenditure statement – which hugely annoys the interest groups receiving concessions on such things as superannuation savings, and the 50 per cent discount on taxing capital gains – by renaming it the “tax benchmark and variations statement”. Not anymore.

The third, even more significant change will be the appointment of an “evaluator-general” to regularly and publicly examine the effectiveness of government spending programs. Many programs don’t do much to achieve their stated objectives, but ministers and their department heads are notoriously reluctant to have them rigorously examined, for fear of embarrassment.

But, as first proposed by economist Dr Nicholas Gruen, such a person and their agency would have similar powers and independence to those of the much-feared Auditor-General. This should work, provided governments couldn’t do what Morrison did to the Auditor-General: cut his funding.

The appointment of an evaluator-general is official Labor policy, and has been championed by the assistant assistant treasurer, Dr Andrew Leigh, whose outstanding economic expertise is negated by his failure to align with any Labor faction.

No doubt Leigh will be keen for the evaluator to make use of the latest in evidence-based decision-making, randomised controlled trials.

The point is that one thing Treasury (and the Finance department) should be hugely knowledgeable about – but aren’t – is what policies work, and what policies don’t. An evaluator-general will fill this vacuum.

Fourth, Treasury will work with Finance Minister and Minister for Women Katy Gallagher to “ensure gender considerations are at the core of our work”, building on last month’s “gender-responsive budgeting”.

Fifth, Treasury will produce Australia’s first “national wellbeing statement” next year, which will be “a hard-headed way to gauge progress by recognising that a robust and resilient economy relies on robust and resilient people and communities”.

And finally, Chalmers will step up production of the Intergenerational Report from five-yearly to three-yearly, in the middle year of each parliamentary term. He promises the document will be “depoliticised”.

It’s true that former treasurer Joe Hockey trashed this exercise by turning it into a blatant attack on his Labor predecessors. It was hard to take subsequent reports seriously, especially when they imposed an artificial cap on tax collections over the next 40 years, while letting government spending run wild.

We need the report to be a much more balanced assessment of future budgetary challenges, not just a Treasury tract on the supposed evils of runaway government spending. We need more acknowledgement of the possible effects of climate change on the budget over the next 40 years – a start to which was made in last month’s budget.

And it would be nice if the report lived up to its name by having much more to say about intergenerational equity issues and trends, such as the effect of ever-rising house prices, and the longer-term consequences of the way the Howard government kept stacking the odds in favour of the old at the expense of the young, particularly favouring the self-proclaimed “self-funded retirees” (who never mention the huge superannuation tax concessions they’ve been given, nor that many of them also get a part-pension).

So, well done, Jim. With better advice and a better “evidence base”, now all Labor needs is the courage to stand up to a few powerful interest groups, including those industries that get the relevant union to plead their case in the new-look Canberra.

A damaged environment leads to an unlivable economy

Economists are paid to worry about the economy, which they usually define fairly narrowly. And, like all specialists, they tend to overemphasise what they know so much about and underrate everything else.

Karl Marx usually gets the credit for saying that, in the economy, “everything’s connected to everything else”. The most conservative economist would agree. The economy is circular because what’s an expense to you, is income to me.

But what applies inside the economy applies equally outside it. Everything inside what we call the economy is connected to everything outside it. What is outside it? The rest of the world – the natural world.

The “economy” sits inside what we call “the environment”. Without the environment, there wouldn’t be an economy. Humans wouldn’t be here, and we wouldn’t need one.

When you step back from our daily preoccupations – at the minute, inflation and interest rates – the bigger picture reveals that economic activity – producing and consuming goods and services – mainly involves doing things to the natural environment: we clear the forest to grow food, scar the countryside to mine minerals, which we manufacture into a thousand kinds of machines.

As we get more prosperous, the population grows, our towns and cities get bigger and we clear more forest to build more houses, roads, highways and bridges. We pull more fish from the sea. We move around a lot. And we power it all by digging up fossil fuels and burning them.

As the population’s grown, but more particularly as consumption per person has multiplied, we’ve done more and more damage to the environment.

But here’s the trick: we’ve hit the environment so hard, it’s started punching back.

That’s why the most important economic event of recent times is not the latest rise in interest rates, it’s last month’s State of the Environment report – whose release was delayed until we found a government with the courage to break the bad news.

The report’s significance is not only its rollcall of how much damage we’ve done so far, but its account of the way that damage is damaging the humans who’ve done it.

We’ve been damaging the environment in many ways – loss of habitat and species, introduction of invasive animals and plants, pollution and waste disposal, salinity and other damage to soil and waterways, overfishing – but the greatest single source of damage, of course, is climate change.

The five-yearly report brings the bad news that climate change is compounding all the other problems. And whereas previous reports warned of future damage from climate change, this one shows it’s already happening – and getting worse.

It documents the extreme floods, droughts, heatwaves, storms and bushfires that have occurred across Australia in the past five years. The immediate effects have been millions of animals killed and habitats burnt, enormous areas of reef bleached, and people’s livelihoods and homes lost.

But there are many longer-term effects still to play out. Extreme conditions put immense stress on species already threatened by habitat loss and invasive species. An extreme heatwave in 2018, for example, killed 23,000 spectacled flying foxes, making them an endangered species.

Many of our ecosystems have evolved to rebound from bushfires. But now that the fires are coming more often and are more intense, the bush doesn’t have enough time to recover, which scientists expect will make it weedy – only those species that live fast and reproduce quickly will thrive.

But enough about plants and animals, what about us? While cyclones, floods and bushfires directly destroy our homes and landscapes, Professor Emma Johnston, of Sydney University, an author of the report, writes that heatwaves kill more people in Australia than any other extreme event.

Heatwave intensity has increased by a third over the past two decades. And climate change worsens air quality through dust, smoke and emissions. The Black Summer of 2019-20 exposed more than 80 per cent of our population to smoke, killing about 420 people.

As Liz Hanna and Mark Howden, of the Australian National University, remind us, clean air is just one of the “ecosystem services” the environment provides to you and me in the economy. Another is clean food. A lot of our recent complaints about the cost of living – the high cost of meat and vegetables, the mythical $10 iceberg lettuce – come from the delayed effect of the drought and the recent effect of the floods.

Yet another service is clean water. But many country towns had to truck in water during the last drought. Land clearing affects water quality. Run-off from agriculture damages water ecosystems and encourages algal bloom and species loss. More than 4 million people depend on the Murray-Darling rivers for their water, but the catchments are rated as poor or very poor.

Finally, the report reminds us that contact with (healthy) nature is associated with mental health benefits, promotes physical activity and contributes to overall wellbeing. Biodiversity and green and blue spaces in cities are linked to stress reduction and mood improvement, increased respiratory health, and lower rates of depression and blood pressure. Enjoy ’em while they last.

Maybe Left versus Right is turning into smart versus not-so

Here’s a funny thing to think about on a holiday Monday: what if all the well-educated people voted Labor and the lowly-educated voted Liberal or National? How would that change our politics? A preposterous notion? Not as much as you may think.

As I’ve mentioned once or twice before, the great political stereotype is that the Liberals are the party of the bosses, while Labor, with its link to the union movement, is the party of the workers. So the people who own and manage the country vote Liberal, whereas the people who do as they’re told vote Labor.

This is the basis for the Liberals' instinctive confidence that they’re the natural party of government. Such belief is reinforced by their having spent far more of the past 75 years in office than their opponent has.

The better-situated, better-off suburbs in any city tend to vote Liberal, while the inner and outer, less-desirable suburbs vote Labor. Most people living in country areas and voting for the Nationals tend to be on modest incomes, similar to the stereotypical Labor voter.

The owners and managers tend to be pretty happy with the world as it is, whereas those further down the pecking order, with less wealth and less income, can always think of things they’d like to see changed. The Liberals defend the status quo, while Labor is the party of “reform”.

This is the basis for the standard perception of politics as a conflict between the privileged Right and the discontented Left.

But what if this conventional setup was changing - being undermined – before our eyes? We all know that strange things happened in last month’s federal election. As usual, we’ve tried to understand these from the top down. How the parties’ share of the national vote changed, then looking by state and even at the 151 electorates.

But Luke Metcalfe, founder of the property and data analytics consultancy, Microburbs, (and, as it happens, a nephew of mine), has done a bottom-up, more “granular” analysis.

He’s taken the Australian Electoral Commission’s voting figures by polling booth and matched them with all the detailed demographic information for corresponding small statistical areas in the 2016 census. They’re not a perfect fit, but they’re a good guide.

Metcalfe finds that “we’re seeing a continuation of the trend in the [2019] federal election, where the Coalition’s support base is shifting towards poorer, less-skilled, less-educated people born in Australia”.

When Labor lost in 2019, many people noticed the swing against Labor in regional mining seats in the NSW Hunter Valley and Central Queensland. What few noticed was the swing to Labor in many safe Liberal seats.

This time, Metcalfe says, rich, educated professionals swung 11 to 12 per cent against the Coalition, while the country’s working poor - the fifth of polling booths paying the lowest rent, earning the lowest incomes and with the least skills - swung only 3 to 4 per cent against it.

As we know, much of this shift away from the Liberals came via the teal independents in Liberal heartland seats in Melbourne, Sydney and Perth. The teal seats’ most dominant characteristic was their high levels of “educational attainment”.

Unsurprisingly, income and education are highly correlated. But Metcalfe says it’s education, not income, that’s doing the driving.

Many people think they’ve detected in recent election results a growing divide between city and country in Australia, but also in Britain and America. But maybe it’s more about the better-educated concentrating in the big cities – where the best-paying jobs are – leaving the less well-educated in outer suburbs or back in country towns, feeling the world has changed in ways they don’t like and thinking of voting One Nation.

Some political scientists think voters in the rich economies are dividing between the globalists and the nationalists. In the same vein, David Goodhart famously explained Brexit as a battle between those who could live and work “anywhere” and those who had to live “somewhere”.

But it still gets down to education and the way ever-rising levels of educational attainment - particularly among women – are remodelling the party-political landscape.

Take climate change. The better educated you are, the more likely you are to accept the science, believe we should be acting, and not be worried about either losing your job in the mine or paying a bit more for power.

Wouldn’t it be funny if the party of the workers became the party of the well-educated, while the party of the bosses became the party of the battlers?

I can’t see that happening, it’s too incongruous. There’s no way the Coalition could get enough seats without the Liberals’ leafy heartland. But it will need radical policy change to get the well-educated back into the fold, or into bed with the Neanderthal Nationals.

Election: a win for the punters against the party professionals

Listening to Anthony Albanese’s victory speech on Saturday night – promising to be a better, more inclusive leader than his predecessor, to help the needy as well as the party heartland, to work hard fixing as many of our problems as humanly possible – my inner accountant came out. Yes, but how will you pay for it all?

If ever there was a case of oppositions not winning elections but governments losing them, this is it. Much more than usually, this election result was voters rejecting not so much the Liberal Party and its policies, but the party’s leader and his divisive, often disrespectful way of conducting himself and his preoccupation with clinging to a fossil-mining past rather than striving for a future as a renewable energy super-power.

What motivated all those people – particularly women – in the most prosperous parts of Sydney and Melbourne to break the habit of a lifetime and vote for a teal independent rather than the Liberal member they had no special gripe against?

It was their overwhelming desire to see and hear no more from the most un-Christlike Christian they could imagine. A bulldozer, indeed. It’s significant that the people they voted for were well-educated, successful businesswomen. Female equality was also a big motivation for the Liberal revolt.

So too, Scott Morrison’s puzzling resistance to the obvious need for a federal anti-corruption commission “with teeth”. If he had nothing to fear, what was his problem?

But it wasn’t just the teals. What about the resurgence in the Greens’ vote, and all the Liberal and Labor voters in Brisbane who switched to the Greens? It’s obvious from the two separate revolts against both major parties that the need for more urgent action against climate change was the election’s single biggest issue.

This despite the majors’ desire to avoid talking about climate change – which the media meekly accepted. It’s significant that both the Greens and the teals were promising much earlier and bigger reductions in emissions. Albanese ignores this message at his peril.

The one issue the majors were happy to debate was the cost of living. So, with the media’s willing acceptance, this became the central issue of the campaign. The great cost-of-living election, with the Reserve Bank making a guest appearance.

Really? Where’s the evidence of that being a key influence on the result? Well, I guess it’s the main reason Labor – the party promising to increase wages – did take a number of seats away from the Libs, in the way the two-party textbook says elections should work.

But we’ve yet to see whether Labor won enough of those seats to form a majority government.

The notion that minority government is a recipe for instability bordering on chaos is a self-serving lie spread by the two majors.

Look at the record – federal and state – and you find that the deals the majors have done to guarantee “confidence and supply” not only achieve stability, they allow the crossbenchers to achieve valuable reforms – often to do with transparency and accountability – that neither of the majors fancies.

With the Gillard minority government, the main gain was a tax on carbon – which, had it survived the depredations of Tony Abbott, would have left us much better-placed today.

We seem to have moved to a non-praying prime minister, but if I were Albanese I’d be praying to be left in a position where I had to let the Greens or the teals impose on me a much more adequate policy on climate change – consistent with the electorate’s now-revealed preference.

This election is no ringing endorsement of Labor, Albo and his small-target policies. The new government has won with an amazingly low primary vote. Timid Labor was not the nation’s first preference.

The election is a step-change in the public’s long-running move away from the two-party system. It was the voters’ message to the Lib-Lab duopoly: “Stuff you and your how-to-vote cards, I’m doing it my way.” If Labor thinks it’s just the Libs with a problem, it’s not thinking.

Albanese’s other problem is that his small-target strategy involved tying one hand behind his back. What he thought he had to do to win government is the opposite to what he now must do to prove himself worth re-electing.

He has inherited a big budget deficit and massive public debt, and will be under great pressure to get that deficit down.

How? He’s promised to deliver the Liberals’ hugely expensive and unfair tax cut in 2024, while promising no tax increases. By cutting spending on health, education, welfare and the NDIS? They’re the things he’s promised to spend more on.

You want to do something about unaffordable homeownership? That requires increasing the tax on home-owners and investors. Where’s Harry Houdini when you need him?

In this election, one critical issue stands above all others

In this campaign we face a bewildering array of problems needing attention: the punishing cost of homes, the appalling treatment of people in aged care, the high cost of childcare, the neglect of every level of our education system, the continuing destruction of our natural environment and the pressure on our hospitals, not to mention the cost of living.

But there’s one problem that’s the most threatening to life, livelihood and lifestyle, the most certain to get a lot worse, the most imminent and the most urgent.

It’s not the cost of living, nor the risk of war with the Solomons (I joke), nor even the dubious behaviour of Scott Morrison and his ministers and their refusal to establish a genuine anti-corruption commission.

I’ll give you a clue: as I write, my fifth grandchild is on the way. I find it hard to believe anyone could be so self-centred and short-sighted as to think any problem could be more important or more pressing than action to limit climate change.

But the pressing need to discover whether the contending pollies have memorised a list of facts and figures has left little time for debating such minor matters as which side has the better policy on global warming.

And, whatever I may think, it’s clear most voters don’t rate climate change that highly. Recent polling by the Australian National University’s Centre for Social Research and Method shows voters rank reducing the cost of living most highly (65 per cent), followed by fixing the aged care system (60 per cent), strengthening the economy (54 per cent), reducing health care costs (53.5 per cent) and – at last – “dealing with global climate change” (just under 53 per cent).

But I’m pleased to say – and you may be surprised to hear – that the nation’s economists are in no doubt on what matters most. Three-quarters of the 50 top economists surveyed by the Economic Society of Australia nominated “climate and the environment” as the most important issue for the election.

Professor John Quiggin, of the University of Queensland, says the key message from the latest report of the Intergovernmental Panel on Climate Change is that “if the world acts now, we can avoid the worst outcomes of climate change without any significant effect on standards of living”.

But the report said it’s “now or never” to keep global warming to 1.5 degrees. Action means cutting emissions from the use of fossil fuels rapidly and hard. “Global emissions must peak within three years to have any chance of keeping warming below 1.5 degrees,” he says.

If you wanted to pick the worst continent to live on as the climate changes, it would be Australia, according to Quiggin. We are a “poster child” for what the rest of the world will be dealing with. Not that we care.

The economic costs of the transition to renewable energy would be marginal, he says. “The required investment in clean energy would be around 2.5 per cent of gross domestic product. That’s far less than the cost of allowing global heating to continue, with costs further offset by clean energy’s zero fuel costs and lower operating costs.”

Voters complain there’s no real difference between the parties, but on climate change we’re being offered the full menu of varying strengths. Climate Analytics, a non-profit research group founded by Bill Hare, has assessed three parties’ policies, plus Zali Steggall’s climate bill, which the teal independents are supporting.

The Liberals have supported zero net emissions by 2050, but refused to increase their commitment to reduce emissions 26 or 28 per cent by 2030. This is judged to be consistent with global warming of 3 degrees, bordering on 4 degrees.

Labor’s target is emission reduction of 43 per cent by 2030. Its plan is supported by the Business Council of Australia. This is judged to be consistent with global warming of 2 degrees, which would be “very likely to destroy the Great Barrier Reef”.

Steggall’s climate bill has a target of 60 per cent reduction in emissions by 2030, which is close to, but within, the upper boundary of modelled 1.5 degrees pathways for Australia. A higher target would give a higher probability of meeting the 1.5 limit.

The Greens’ target of a 74 per cent reduction by 2030 is judged consistent with limiting warming to 1.5 degrees. Some parts of the Barrier Reef would survive. Globally, the most extreme heat events could be nearly twice as frequent as in recent decades. In Australia, an intense heat event that might have occurred once a decade in recent times could occur every five years and would be noticeably hotter. Phew.

If you’ll forgive a little colourful characterisation, the choice ranges from the Liberals’ “let’s just say we’ll do something, so we don’t offend Barnaby and his generous donors” to Labor’s “let’s do a lot more than the Libs, but go easy on coal and coalminers” to the Greens’ “let’s not muck about”.

And the many Liberal voters in the party’s leafy heartland who really do care about climate change now have a way to make their views felt.
