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.”

Climate change: we can't stop it by refusing to change

After Donald Horne's book in the 1960s, we all know we live in the Lucky Country. What we've forgotten until now, however, is the qualification Horne added: "Australia is a lucky country run mainly by second-rate people." We haven't been feeling so lucky this burning, smoky summer. But our present leader, Scott Morrison, has certainly been looking second rate.

This summer we've had our Pearl Harbour moment. Just as the Japanese bombing of Hawaii in 1941 stopped Americans viewing World War II as some distant threat, so our season of unprecedented drought, heatwaves, bushfires and smoke haze has woken us up to the present reality of global warming.

There we were thinking climate change would be a problem for our children and grandchildren – who, we hoped, wouldn't remember our refusal in 2013 to pay a bit more for electricity so as to reduce greenhouse gas emissions.

Now we realise it's a problem – a frightening problem – for us. One likely at least to continue for the rest of our lives at its present level of harm and unpleasantness, and more likely get much worse in the years ahead unless something decisive is done by all the major economies, including us, to reduce net emissions to zero over the next 30 years and stop us cooking.

It's a wake-up moment not just for us, however, but for the entire rich world. They've been watching in fascinated horror as global warming has punished the Aussies for their repeated refusal to take it seriously.

Ostensibly, Morrison has realised we need to change course. "We want to reduce emissions and do the best job we possibly can and get better and better at it," he said when it dawned on him we were holding him responsible for the fires regardless of what the constitution says about them being a state responsibility.

"In the years ahead, we are going to continue to evolve our policy in this area to reduce emissions even further," he said. But then he started adding qualifications. "We're going to do it without a carbon tax, without putting up electricity prices and without shutting down traditional industries upon which regional Australians depend for their very livelihood."

Really? Sounds like he's promising us all the benefits without any of the costs. Nothing needs to change to make things much better. Which, in this age of cynicism and distrust of our lengthening string of second-rate leaders, makes you fear all that's changed is the marketing spiel.

What we need is a leader great enough to seize our Pearl Harbour moment and turn it into a Port Arthur moment – the moment when a prime minister exercises true leadership and uses the horrible reality of death and destruction to win public support for big changes to stop such things becoming regular events.

John Howard, Morrison's role model and mentor, saw such an opportunity and seized it. He did so not because it offered political gain, but because it was a leader's duty to deliver something great for those he led. He did so knowing it would prompt great resistance from within the Coalition. But with the public behind him and his political opponents unlikely to oppose him, that was a risk he was prepared to take.

Just the same conditions apply to Morrison's decision on whether to turn us from laggards to leaders in the global effort to halt the rise in average temperatures to less than 2 degrees. Has he the courage to stand up to the noisy minority of climate change deniers in the Coalition, who are now so badly out of step with public opinion?

There's a central lesson to be learnt from this appalling summer. The dichotomy Morrison has so far relied on – the environment versus the economy – is false. "We'd love to help the environment, but not if that involves a cost to the economy."

Sorry, since the economy sits within the natural environment, anything that damages the environment also imposes loss – of property, businesses, jobs, wellbeing, lives and health – on the economy and the humans who constitute it.

It follows that, in our obsession with the cost of fighting climate change, we can no longer ignore the far greater cost of not fighting it. The one option that's not available is no change. We can refuse to change, but nature will change things whether we like it or not.

The economy is always changing, as some industries expand and other contract. Jobs are continuously being lost in some fields and created in others. This is the very process by which we've become far more prosperous over the past two centuries.

So the notion that our steaming coal industry can be preserved in aspic is laughable. Its days are numbered. But we don't have to kill it, the rest of the world will do that for us as – like us – they increasingly turn to renewable energy and away from fossil fuels. Business can see that; Morrison professes not to.

Second-rate leaders throw in their lot with those who fear losing from change, letting the rest of us suffer while they attempt to resist the irresistible. First-rate leaders seek out ways we can benefit from that change, restoring the luck of the Lucky Country. How? Watch this space.

Is Morrison the man who killed the Aussie summer?

This is the summer from hell. I can’t imagine anyone is enjoying their break – not with the quadruple whammy of drought, heatwaves, bushfires and smoke haze we’re experiencing. If it happens again next summer – or the one after – as it very well could, can you imagine the political doghouse Scott Morrison and his Coalition parties will be in?

Morrison is already bearing most of the ire of people displaced by the fires. So much so that he’s learned not to show up to offer his commiserations. But is it really his fault? No. Just one of the six prime ministers we’ve had over the past two decades can hardly take all the blame.

In any case, Morrison is right to protest that nothing Australia could have done by itself could have stopped the deterioration in climate we’re seeing. The only solution is global, so all the big, rich economies – particularly the Americans, less so the Europeans – must share the blame for the continuing rise in average temperatures.

And even the biggest developing economies – China and India, particularly – could have done more to reduce the intensity of their emissions (emissions per dollar of GDP) without abandoning their efforts to raise their living standards to some higher fraction of those we have long enjoyed.

But Morrison doesn’t escape the responsibility of leadership as easily as that. For one thing, it’s his side of politics that’s done most to sabotage the limited and belated efforts Australia has made, since the defeat of the Howard government, to contribute to the global effort to reduce greenhouse gas emissions.

And you have to go back to John Howard’s refusal to ratify the Kyoto agreement of 1997 to find an instance of Australia actively disrupting efforts to reach international agreement on stronger action, to match the shamefully destructive contribution Angus Taylor made at the conference in Madrid last month by insisting that Australia be allowed to use an accounting trick to shirk its responsibilities.

For any Australian leader to claim, hand-on-heart, to have done all they reasonably could to reduce global warming, they have to be able to say they committed us to a disproportionate reduction in our emissions, so as to have the moral authority to press the bigger players to do more. None of our leaders can say that, least of all Howard and Morrison.

And then there’s the law of politics that says if it's fair enough for the government of the day to claim the credit when things go well – even when the seeds of that success were sown by an earlier administration – it’s equally fair for the government of the day to cop the blame when the neglect of earlier administrations finally hits the fan, as it has this summer.

Not Morrison nor any of his predecessors can honestly claim to have been caught unawares by what’s happening before our eyes and noses. The CSIRO has been warning for at least a decade of just this concurrence of adverse and costly events – in lives and health, as well as property – as the planet warms.

At last year’s election, the climate change deniers demanded to be told the economic cost of stepping up our contribution to reducing global warming. The more sensible among us should have been demanding to be told the economic cost of allowing global warming to roll on. We’re finding that out as we speak, but doing so the hard way.

It’s tempting to wonder whether, in his heart of hearts, Morrison is himself a climate-change denier. But that hardly matters. These days, what politicians truly believe doesn’t have much bearing on what they do and say. Conviction politics is dead. These days, politicians seek out the position that, while sitting easily with their heartland supporters, is likely to give them the greatest short-term advantage over their political opponents.

Whatever he believes, Morrison is too cagey to come out as a denier. Like Malcolm Turnbull before him, he’s bound hand-and-foot by the deniers in his own party and the Nationals. So, until now, his safest position has been to say he accepts the science, while falsely claiming to be comfortably on target to reach the (inadequate) emissions reduction we committed to in the Paris agreement.

There are two approaches to the “wicked” problem of global warming: mitigation (reducing emissions) and adaptation (changing in response to whatever warming we get). The greenies have seen these as in conflict and frowned on efforts to adapt. But Morrison and his predecessors have been so bound up by their deniers that they haven’t wanted to talk about even such issues as getting set to cope with much worse bushfire seasons. No excuses for that, Scott.

Government on the cheap leaves us burningly reliant on charity

As the cast were taking their bows at the end of a show before Christmas, one of them stepped forward to say that, as we left, we’d be approached by people with buckets collecting for the NSW Rural Fire Service. Normally I’d reach for my wallet – I’d done so a few weeks earlier when they were collecting for an actors’ charity – but this time I declined.

Like Victoria’s Country Fire Authority, the RFS is staffed by volunteers. Why did they need donations? Presumably, to help cover the cost of needed equipment or incidental expenses. Really? What’s happened to the state government’s cheque book? And don’t I remember hearing that the RFS had had its funding cut?

No one believes every worthy cause should be funded by the government so that private charity becomes redundant. And it’s true the federal government partially subsidises donations by making them tax-deductible. But where do you draw the line between what the government should cover and what can be left to the generosity – or otherwise – of private citizens?

The more I think about it, the more I realise that, as part of their commitment to Smaller Government and lower taxes, governments have been quietly shifting the dividing line between what the government pays for and what should depend on charity.

All governments have been doing it. State governments, for instance, have long left country (but not city) fire-fighting to volunteers. And have long underfunded the upkeep of public schools, believing parents and citizens can be left to make up the shortfall. But it’s been a particular trick of the federal Coalition government as it struggles to return its budget to surplus when there are expensive, vote-buying tax cuts to be covered.

If you’re wondering why, despite his contrition at having taken an overseas break his spin doctors tried to keep secret, and his freely dispensed “thoughts and prayers”, Scott Morrison remained adamant for so long that all that was needed was already being done to help the firefighters, it’s because he knows that too much generosity on the feds’ part could see his precious budget surplus whittled down to nothingness.

Since its election in 2013, this government has been insistent that the budget should be returned to surplus by cutting government spending, not by explicit increases in taxes (hidden tax increases caused by bracket creep are okay, of course, because the punters don’t notice ’em).

Its first budget in 2014 was a long-term plan to improve the budget by what the bureaucrats call “cost-shifting”. Much of the cost of health and education was to be shifted onto the states’ budgets. Some was to be moved to your household’s budget via the $7 charge for visits to the doctor.

That budget was so badly received most of those plans were reversed. But Finance Minister Mathias Cormann and his accountants have continued to limit the growth in government spending by penny-pinching in ways that voters wouldn’t notice or object to.

They’ve got welfare dependency to “its lowest level in 30 years” not by getting the unemployed into jobs, but by using petty excuses to suspend people’s dole payments. How do these unfortunates live without money to live on? They fall back on their families or go cap-in-hand to the Salvos or Vinnies. Get it? The feds are cost-shifting to charities – the same community groups whose grants they’ve cut back.

According to a recent survey of its members’ staffs by the Australian Council of Social Service, 76 per cent of staff dealing with housing the homeless reported an increase in demand, as did 71 per cent of those providing financial counselling and support (aka money). Respondents to the survey said the unmet demand naturally had adverse impacts on the community. Where people fall through the cracks they can end up in hospitals or the justice system (cost-shifting to the states).

I’ve been reading about how many small country towns are relying on newly formed charities for their supply of water. More broadly, the desire to limit government spending encourages politicians to ignore reports warning of looming troubles and push problems off into the future. Some of the foreseen problems fail to materialise, but many eventually reach crisis point and can no longer be ignored.

The aged care royal commission is revealing the shocking results of one attempt to keep government small by relying on for-profit providers, underspending on the provision of home-care packages and on policing institutions’ adherence to the rules.

Which brings us back to our truly heroic volunteer firefighters. Morrison’s reluctant decision to pay them $300 a day for a maximum of 20 days is the least he can do to acknowledge their loss of income (or annual leave) while serving their communities.

His reluctance – and anxiety to emphasise it’s not a payment of wages – is understandable, however. Behavioural economics is clear that paying people to do what they formerly did without payment can kill the motivation to donate your services for noble reasons. Morrison has stressed that this response to a problem of unprecedented severity shouldn’t be seen as setting a precedent.

Good luck with that. If climate change is making drought, heatwaves and bushfires bigger and more frequent, the horrific events of this summer will become a regular occurrence – meaning the days of leaving bushfire fighting to unpaid volunteers are numbered.

Don't worry, climate change is just imaginary

As we've sweltered through this terrible summer – and lately, as bushfires have raged – what a comfort it's been to know that climate change doesn't exist and isn't happening.

Or, if it does exist, it's not caused by anything humans have done, so there's nothing we can do about it.

Or, if it is caused by humans burning fossil fuels for the past 200 years, let's say we've got a policy to deal with it, go to international conferences and make pledges to act, then come home and not do much about it.

That way, we'll have all bases covered: something to calm the consciences of those still silly enough to believe climate change is real, but not enough to annoy the party's many climate change deniers, nor our generous donors in the coal industry.

And, just to make you feel better, let me remind you of the big win the deniers have had. The Coalition's leading, longest-standing and most articulate supporter of action on climate change has changed sides.

Malcolm Turnbull, the man who lost his job as party leader because was so keen to see action he supported the Labor government's emissions trading scheme, is now keen to ensure it never happens again.

The squeakiest wheels in the party want him to demonise renewable energy, blaming it for all the blackouts and price rises?  Introduce new government subsidies for coal while making the future for power generation so uncertain no one's game to invest in anything?

Sure. Whatever it takes.

(Don't worry, Malcolm, I'm sure all the people inside and outside the Liberal fold who were so pleased when you became Prime Minister – me included – will learn to accept your need to abandon everything we know you believe and start doing Tony Abbott impressions.)

It's the easiest thing in the world for people to imagine that whatever's been happening lately is much bigger and more terrible than ever before.

Trouble is, the scientists keep confirming our casual impressions.  A report this month prepared by top climate scientists for the independent Climate Council, is all bad news.

They say all extreme weather events in Australia are now occurring in an atmosphere that's warmer and wetter than it was in the 1950s.

"Heatwaves are becoming hotter, lasting longer and occurring more often," they say.

"Extreme fire weather and the length of the fire season is increasing, leading to an increase in bushfire risk."

This fits with the findings of the latest biennial CSIRO and Bureau of Meteorology State of the Climate report.

According to the bureau's Dr Karl Braganza, Australia is already experiencing the effects of climate change, with record-breaking heat now becoming commonplace across the country.

"Australia experienced its three warmest springs on record in 2013, 2014 and 2015," he says. "Temperature and rainfall during this period is critical to southern Australia's fire season.

"We've already seen an increase in fire weather and a longer fire season across southern and eastern Australia since the 1970s.

"In these regions the number of days with weather conducive to fire is likely to increase.

"Whilst the observations show us increased rainfall in some parts of Australia, we have also seen significant seasonal decline, such as in the April-October growing season, where an 11 per cent decline in rainfall has been experienced in the continental southeast since the mid-1990s.

"The changing climate significantly affects all Australians through increased heatwaves, more significant wet weather events and more severe fire weather conditions.

"Some of the record-breaking extreme heat we have been seeing recently will be considered normal in 30 years' time."

Oh, good.

Of course, none of this is having any effect on agriculture. It must be a great comfort to our farmers to know that, by order of Barnaby Joyce and the National Party, climate change is a figment of the climate scientists' imagination.

This is good news, since I read that reliable rainfall and predictable temperature ranges are critical to agricultural production, and these are the very factors affected by a changing climate – if it was changing, which it isn't.

A new CSIRO study, led by Dr Zvi Hochman, has found that Australia's average yields from wheat-growing more than tripled between 1900 and 1990 thanks to advances in technology, but have stalled in the years since then.

The study found that, since 1990, our wheat-growing zone had experienced an average rainfall decline of 2.8 millimetres, or 28 per cent per cropping season, and a maximum daily temperature increase of about 1 degree.

Australia's "yield potential" – determined by climate and soil type – which is always much higher than farmers' actual yields, has fallen by 27 per cent since 1990.

So all the efforts farmers have made to improve their yields with better technology and methods have served only to offset the effects of climate change, leaving them no better off.

"Assuming the climate trends we have observed over the past 26 years continue at the same rate, even if farmers continue to improve their practices, it is likely that the national wheat yield will fall," Hochman says.

He says these findings would be broadly applicable to other cereal grains, pulses and oilseed crops, which grow in the same regions and season.

But not to worry. They're only scientists. What would they know that our pollies didn't want to know?
