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.

Wars, floods and pestilence: these horrors have an economic upside

By profession, economists are hard-nosed and cold-blooded. The pictures we’re seeing of the death and destruction wreaked by Russia in its invasion of Ukraine are heart-wrenching. At home, seeing people perched on their roofs as floodwaters surge, or piling up the ruined contents of their homes on the footpath, makes your heart go out. But what economists see is that every disaster has its upside.

Once they’ve put on their professional’s hat, economists don’t see evil, or pain or any emotion. Feelings must be suppressed when what they need is objectivity.

They simply size up wars and natural disasters for the effect they’ll have on the economy, measured by inflation, unemployment and, above all, gross domestic product. And since GDP often ignores the destruction of buildings and other assets, but plays close attention to the building of new assets, it tends to paint an overly favourable view of events we see as disastrous.

This doesn’t make GDP an instrument of evil that should be banished. It’s simply mono-dimensional. It focuses on a vital, but narrow aspect of our lives – how much we produce, how much income we generate – while studiously ignoring all the other aspects.

When someone’s house has been declared uninhabitable, you and I see how painful and disorienting that must be for them. What an economist sees is all the jobs that will be created and income generated to build them a new one.

But until then, the family will be homeless! That’s OK. Those who provide them with somewhere to live will be earning income and employing people – provided they don’t just stay with family or neighbours. It’s not counted in GDP if no money changes hands.

GDP doesn’t measure wellbeing – and was never designed to. This is only a problem when people fall into the trap of thinking GDP is all that matters – an occupational hazard for economists.

Last week’s budget papers discussed the economic consequence of the war in Ukraine and the floods in NSW and Queensland. For such terrible events, the tone was surprisingly upbeat.

Combined, “the Russian and Ukrainian economies comprise less than 3 per cent of global GDP and less than 2.5 per cent of global trade.

“Foreign financial exposures to Russia are small, and the International Monetary Fund has assessed that sovereign [government] or bank default is not a systemic risk to global financial stability.”

Russia is, however, an important global supplier of rural, mineral and energy commodities. So the invasion has caused substantial disruption in global commodity markets, the papers say, and has the potential to significantly raise inflation and lower global growth.

“Russia produces 18 per cent of the world’s gas and 12 per cent of the world’s oil supply and, together with Ukraine, accounts for around 25 per cent of world wheat exports.” The invasion has increased the risk of supply disruptions, pushing up energy, agricultural and metals prices.

“Global supply chains are also reliant on Russian metals exports, especially palladium [a rare metal used in catalytic converters of exhaust fumes, and fuel cells], so significant supply disruption could have flow-on effects for global manufacturing supply chains.”

All economies will be affected by the rise in global commodity prices. Among the worst affected will be Europe, Japan and South Korea, which are highly dependent on imports of energy. These and other countries will suffer what economists call a “negative terms-of-trade shock” – that is, the prices of their energy imports will rise relative to the prices they get for their exports.

But, the papers say, a smaller set of countries will benefit from a “positive terms-of-trade shock” – because they are net exporters of the higher-priced energy commodities. Their consumers and businesses will pay the higher world price for the petrol and other fuels they use, but this will be greatly offset by the higher prices their producers of energy exports will be receiving.

Among this small group is one lucky country whose net energy exports are twice as great as its domestic energy use. It’s Austria. Sorry, make that Australia. As the economist Chris Richardson might say, you may be paying a lot more for your petrol, but the economy’s been kicked in the backside by a rainbow.

Turning to our floods, although it’s still raining and too soon for final figures, last week’s budget papers say that, under an arrangement where the federal government funds up to 75 per cent of the assistance provided by the state governments, the feds expect to pay more than $2 billion for income support to households, temporary accommodation and social services, about $600 million for community clean-up and recovery, and almost $700 million to businesses and farmers for repairs, new equipment and support services.

As well, the budget makes provision for $3 billion in further federal spending over the coming four years.

Moving from the budget to the economy, we’re told that the “direct economic cost” – that is, those purely monetary costs that show up in GDP – are expected to subtract about 0.5 percentage points from the growth in the nation’s real GDP during the March quarter.

What are the costs that show up in GDP? They’re mainly reduced production in the mining, agriculture, accommodation and food services, retail trade and construction industries.

You’ll be relieved to hear, however, that this 0.5 per cent overstates the net impact of the floods on real GDP over the longer term.

Why? Because “this direct cost will be partially offset by increased investment to replace and rebuild damaged housing, infrastructure and household goods”.

And here’s some good news: the reduced exports of coal caused by rain in the March quarter aren’t expected to be as bad as previous weather events, such as the floods and Cyclone Yasi in 2011.

If you find all this mercenary and distasteful, it’s not new. The arrival of World War II helped end the Great Depression. And rebuilding bombed out Europe and Japan after the war helped the rich countries grow faster than ever before – or since.
