(The Conversation) Australia Is At Risk Of Taking The Wrong Tack At The Glasgow Climate Talks, And Slamming China Is Only Part Of It

Buried within the prime minister’s response to the latest report from the Intergovernmental Panel on Climate Change is just about everything we’re at risk of getting wrong at the Glasgow climate talks in October.

After slamming China — whose emissions per person are half of Australia’s — for not doing more to cut emissions, Scott Morrison said the Glasgow talks were the “biggest multilateral global negotiation the world has ever known”.

If he treats the talks as just another (big) negotiation, we’re in trouble.

The way the Department of Foreign Affairs and Trade usually treats negotiations is hold something back, hold out the prospect of “giving it up,” and then only make the concession if the other side gives something in return. Even if holding back damages Australia.

Cars are a case in point. From an economic point of view, there is no reason whatsoever to continue to impose tariffs (special taxes) on the import of cars — none, not even in the eyes of those who support the use of tariffs to protect Australian jobs. Australia no longer makes cars.

Yet the tariff remains, at 5%, making it perhaps A$1 billion harder than it should be for Australians to buy new cars (although nowhere near as hard as it was in the days when the tariff was 57.5%).

The tariff seems to be in place largely to give the Department of Foreign Affairs and Trade something to negotiate away in trade agreements: for use as what the Productivity Commission calls “negotiating coin”.

Here’s how it worked in the 2014 Australia-Korea Free Trade Agreement. Australia agreed to remove the remaining 5% tariff on Korean cars, “with consumers and businesses to benefit from downward pressure on import prices”.

But Australia didn’t remove the tariff on car imports altogether, which would have given us a much bigger benefit but denied the department negotiating coin.

The next year the department did it again, agreeing to give up the tariff on imported Japanese cars in the Japan-Australia Economic Partnership Agreement (but not on other cars) so Australians could “benefit from lower prices and/or greater availability of Japanese products”.

Two years later, it did it again, with cars from China.

When the UK and European agreements are negotiated, it’ll do it there too.

Australia holds back reforms

Eventually Australians will get what they are entitled to. But the point is that rather than advancing the cause of free trade, the department has held back, treating a win for the other side as a loss for us, when it wasn’t.

The Centre for International Economics believes the much bigger earlier set of tariff cuts lifted the living standard of the average Australian family by A$8,448.

Had our trade negotiators been in charge, we would still be waiting. Instead the Hawke and then the Keating governments pushed through unilateral reductions, asking for nothing in return.

As former Trade Minister Craig Emerson put it, this gave Australia “credibility in international trade negotiations way beyond the relative size of our economy”.

Does that sound like the sort of thing Australia might need at Glasgow, to have enough credibility to urge even bigger emitters to deliver the kind of cuts on which our futures and future temperatures depend?

It won’t work with China

The prime minister is right to say that China is the world’s biggest greenhouse gas emitter, even though its emissions per person are low. Its high population means it accounts for 28% of all the greenhouse gases pumped out each year. The next biggest emitter, the United States, accounts for 15%

But China’s status is new. Until 2006 it pumped out less per year than the United States. Because the US has had mega-factories and heating and so on for so much longer, it is responsible for by far the biggest chunk of the greenhouse gasses already in the atmosphere: 25%, followed by the European Union with 22%.

China might reasonably feel that countries like the US that have done the most to create the problem should do the most to fix it.

Like Australia, the US pumps out twice as much per person as China and has much more room to cut back.

On the bright side, China knows that being big means it is in a position to make a difference to global emissions in a way that other countries cannot on their own. And that’s a position that can benefit its citizens.

China’s latest five-year plan, adopted in March, commits it to cut its “carbon intensity” (emissions per unit of GDP) by 18%. If it beats that five-year target by just a bit (and it has beaten its previous five-year targets) its emissions will turn down from 2025.

It is aiming for net-zero emissions by 2060.

Australia needs China’s help

The Intergovernmental Panel on Climate Change finds that Australia is especially susceptible to global warming. We’re facing less rain in winter, longer heatwaves, drier rivers, more arid soil and worse droughts.

We are right to want China to do more, but the worst way to achieve it is to say “we won’t lift our ambition until you lift yours”.

Hardly ever a worthwhile strategy, it is particularly ineffective when we don’t have bargaining power.

The only power we’ve got is to set an example, unilaterally, as we did with tariffs. And to ramp up our ambition.

If Australia said it would do more, and didn’t quibble, it might just count for something.

It’s all we can do, and it’s the very best we can do.

(AU ABC) Australia Widely Criticised Over Emission Reduction Targets Ahead Of COP26 Climate Talks

This week has seen the UK, the US and others pile onto Australia's approach to climate change at a virtual conference on climate action.

The US President's deputy special envoy for climate change, Jonathan Pershing, told the Better Futures Forum on Thursday our current emissions reduction commitments were not enough.

"It would be really helpful to see Australia step forward with a more ambitious effort," Mr Pershing said. "I would submit that Australia could be much more aggressive."

Later in the day, the UK's Minister of State, Alok Sharma, who is president of the upcoming climate conference in Glasgow, called on Australia to do more.

"I urge Australia to step up with big, bold commitments ahead of COP26 in November," he said.

At the same conference earlier this week, former UN chief Ban Ki-moon said not taking more action risked Australia's international standing, and NSW Liberal environment minister Matt Kean said Australian climate politics needed to move beyond vested interests.

Australia is copping it from all sides. Why now?

Ahead of COP26 in Glasgow, the world wants tougher targets

In just over 70 days, the world is meeting in Glasgow for COP26, as the next round of UN climate talks are known.

At the meeting, countries are expected to announce new and more ambitious emissions reduction targets.

As Mr Pershing explained, the UK is leading the pack, with a pledge to cut emissions by 68 per cent by 2030. The EU has pledged a 55 per cent reduction and the US 52 per cent. 

The world needs to cut emissions roughly in half by 2030, and rich countries such as Australia are expected to lead the way.

But Australia has stuck with the same commitment it made in 2015 under Tony Abbott: 26-28 per cent below 2005 levels by 2030.

At the same time, all our major trading partners have committed to a net zero target, but Australia has so far resisted.

Ban Ki-moon put it bluntly: "Australia's current goal of a 26 to 28 per cent reduction on 2005 levels by 2030, and the absence of a national zero emissions target, is out of step with its states, its trading partners, and other comparable nations. It is insufficient to meet Australia's Paris Agreement commitments."

There are other things Australia can do, too

Many expect Australia will announce a net zero by 2050 target ahead of Glasgow.

But without stronger interim targets for 2030, that is unlikely to satisfy our global friends and neighbours.

COP26 will involve important discussions that go beyond emissions pledges, which could offer room for Australia to generate goodwill.

The IPCC report explained

How money will be mobilised to help the developing world mitigate and adapt to climate change is going to be an important discussion.

There was a target of mobilising $US100 billion ($139.5 billion) of global finance by 2020. How that's measured is a matter of some debate, but most agree the target has not been met.

Australia has a chequered history on the issue.

Under the Abbott government, Australia supported the Green Climate Fund, which seeks to raise finance to assist the developing world.

Australia even chaired it.

When Scott Morrison became Prime Minister, following Donald Trump's lead, he withdrew Australia from the fund, telling talkback radio he would not "tip money into that big climate fund".

Australia did stand by its commitment to provide climate finance, just through other channels.

The latest IPCC report does not make for particularly uplifting reading. But if you are keen to delve further into the details, it does say quite a bit about Australia. Read more


Despite that, the move was condemned by some of our Pacific neighbours, and now the US has rejoined the fund, Australia is the only developed country not part of it.

Australia could probably win some goodwill by playing a constructive role in discussions around finance.

There are other options. Mr Pershing suggested Australia could help reduce its impact on emissions in other countries too by reducing its coal exports. And important negotiations will take place around adaptation targets and carbon markets as well.

What about Australia's 'technology, not taxes' approach?

Mr Morrison has been ardent in his promotion of "technology, not taxes" as a way of tackling climate change.

This is a reference to the Coalition's Technology Investment Roadmap, which guides $18 billion into five priority areas: hydrogen, carbon capture and storage, soil carbon, energy storage options and "low-carbon" steel and aluminium production.

The initiative does have international support, acknowledging technological breakthroughs in these areas could help both developed and developing countries alike lower their emissions in the future.

But it doesn't cut it as an emissions reduction target.

There is no guarantee these technological breakthroughs will happen at all, let alone quickly and successfully enough to make them competitive with existing methods of electricity generation and manufacturing in the next decade.

The US, UK and others want Australia to commit to targets and time frames. That way, if the technological breakthroughs don't happen, Australia will be compelled to find other ways to reduce emissions.

How does Labor's policy stack up?

With a federal election due sooner rather than later, it is possible the ALP, rather than the Coalition, could be dealing with climate change policy.

Labor leader Anthony Albanese has already committed to the net zero by 2050 target and Shadow Minister for Climate Change and Energy Chris Bowen has now acknowledged stronger interim targets are needed as well.

"Net zero emissions by 2050 is necessary, but not sufficient," he told the Better Futures Forum.
"A strong roadmap there is important, too."
But he declined to outline what that would involve, beyond the vague statement: "Australia should take a higher medium-term target to COP26 in November."

Labor's centrepiece energy policy is the $20 billion Rewire the Nation plan, which would see direct investment in the energy transmission network.

That investment is needed to accommodate the growth in wind, solar and hydro-power generation scattered around the countryside, not to mention the growth in rooftop solar feeding into what used to be a one-way grid.

But, like the Coalition's Technology Investment Roadmap, it doesn't hold Australia to account to meet its share of emissions reduction in a feasible time frame to limit global warming.

So how will this play out?

In the next 70 days, we can expect to see the US, UK and other developed countries ratchet up the pressure on Australia.

Minister for Energy and Emissions Reduction Angus Taylor is standing firm on the government's approach for now.

"While ambition is important, outcomes are what ultimately matter," he said. 

"Over the last two years, our position against our 2030 target has improved by more than 639 million tonnes. That is equivalent to taking all of Australia’s 14.7 million cars off the road for 15 years."   

"Australia will continue to act in a practical, responsible way to be part of the global solution to reduce emissions without destroying jobs or regional communities."

The US and UK are currently coaxing and cajoling Australia, but expect more muscle flexing if Australia doesn't show that it is willing to come on board with stronger action.

The EU is forging ahead with a "Carbon Border Adjustment Mechanism", a bureaucratic name for a tariff on goods that are produced in nations that don't meet emissions reduction benchmarks.

Mr Biden has indicated the US intends to follow suit with a similar trade policy.

If Mr Morrison does not do enough to convince the world Australia is serious about contributing to global emissions cuts, as Ban Ki-moon warned, the nation's reputation and its trading strength could be badly damaged.

(AU Canberra Times) Resources Industry Must Clean Up Its Act Or Get Out Of The Way

Canberra Times - Michael Allen

Fossil-fuel industries and their peak bodies are adept at painting themselves as partners on the way to climate solutions. Give me a break. Picture: Shutterstock

Author

Michael Allen is a former chief financial officer for listed resource companies and has worked in senior executive positions for companies including AngloGold, Anglo American and Resolute Mining.
He is treasurer of renewable-energy think tank Sustainable Energy Now.

As someone who has worked in the resources industry for three decades, much of it as a chief financial officer for major mining companies, it has been frustrating over the past week to see how the oil and gas industry has tried to position itself as part of the solution to lowering emissions and tackling climate change - rather than acknowledging it is a large part of the problem.

Let us be clear at the start: gas is a fossil fuel that's driving climate change.

Methane concentrations in the atmosphere are not only continuing to grow but accelerating. Experts like the Climate Council's Professor Will Steffen, the former executive director of the ANU's Climate Change Institute, largely attribute this increase to the gas industry's expansion.

This is what exacerbating climate change looks like - not solving it. The industry's mouthpiece, the Australian Petroleum Production and Exploration Association, simply has no valid claim to being part of the solution when it and its members are aggressively pushing to expand gas extraction.

Parts of our economy today still rely on oil and gas, but the only course of action compatible with net-zero emissions and a safe climate is to spare no effort in the transition to cleaner options like renewable energy or alternative materials - not prolonging existing, dangerous incumbents like gas.

It is also a cop out for the gas industry to mention the royalties companies pay, without also mentioning the billions of dollars of public subsidies the industry receives and the minimal tax many of those same companies pay. Let's see them published together.

Instead, to protect their profits, fossil-fuel companies have perpetuated decades of misinformation about climate change, spent billions on political donations to stall climate action and secured public funding for a "gas-led recovery".

When it comes to climate change, fossil fuels - like coal, oil and gas - are the cause, because they are the biggest driver of greenhouse gas emissions.

(Grist) New UN Report Could Be A Game-Changer For Climate Lawsuits

Grist -  

"The IPCC report should be a sort of rallying call to lawyers."

The United Nations Intergovernmental Panel on Climate Change’s sixth assessment report, released on Monday, contained some of the group’s strongest language yet affirming the link between human activity and global warming.

Humans have “unequivocally” warmed the planet, the IPCC report said, making heatwaves, droughts, and wildfires more extreme in the process. While that might seem like a no-brainer to some, it’s a finding that could have big implications for lawsuits seeking to hold polluters accountable for disaster damages.

“The IPCC report should be a sort of rallying call to lawyers,” said Rupert Stuart-Smith, a climate researcher at the University of Oxford, “to ensure that they are making use of the most up-to-date developments in climate science.”

The specific field of science that examines the connection between extreme weather events and human activity is called “climate change attribution.” According to the IPCC, scientists have gotten much better at this over the past decade, and can now more rigorously pin extreme heat, heavy precipitation, dry spells, and hurricanes on big carbon emitters.

For years, plaintiffs around the world have sought to hold fossil fuel companies accountable for their contributions to climate change — often seeking compensation for damages like economic losses from floods or wildfires. But these cases have been stymied by a lack of causal evidence. That is, plaintiffs have struggled to prove in the courtroom that they have suffered economic damages due to the activities of the oil and gas companies they are litigating.

Take, for example, the 2008 case of Native Village of Kivalina v. ExxonMobil Corp., in which Native Alaskans sued ExxonMobil and 23 other energy giants for damages associated with coastal erosion. The plaintiffs said the erosion had been exacerbated by climate change.

But the U.S. Court of Appeals dismissed the villagers’ case, citing a dearth of causal evidence. “It is not plausible to state which emissions — emitted by whom … and at what point in the world — ‘caused’ Plaintiffs’ alleged global-warming related injuries,” the court ruled.

According to Stuart-Smith, however, that’s no longer true. Thanks to the rapidly advancing field of attribution science, researchers now have the tools needed to attribute natural disasters to human-induced climate change, and to determine individual companies’ contributions to them.

“This kind of scientific evidence exists, the methods are robust, and they’re widely accepted in the scientific community,” Stuart-Smith said.

But that evidence isn’t yet being used in the majority of climate-related lawsuits. According to a paper Stuart-Smith co-published in Nature Climate Change this June, plaintiffs tend to claim that they have been damaged by oil and gas companies’ contributions to climate change without citing strong enough evidence: Nearly three-quarters of of the 73 cases analyzed in the study didn’t refer to any peer-reviewed attribution studies at all.

Those that did incorporate attribution science tended to do so in a general way, drawing broad links between emissions and climate change impacts, rather than making a causal link to specific damages sustained by the plaintiff.

To build a better legal case in climate lawsuits, Stuart-Smith said, plaintiffs must first establish the contribution of an individual emitter to climate change using what’s known as source attribution. In other words, “How much has an individual fossil fuel company contributed to climate change?” Stuart-Smith explained.

That calculation may be easier than it sounds, considering there is already a robust and well-used body of literature on the topic. Much of the field builds on seminal research from the Climate Accountability Institute, which in 2014 published a paper quantifying the top fossil fuel companies’ contribution to global warming.


“We’re citing the hell out of it,” said Pat Parenteau, a law professor at Vermont Law School. 

But Parenteau said legal groups could do more with newer attribution science tools focused on “impact attribution,” which can draw a direct line between human activity and the consequences of climate-related extreme weather events.

For example, earlier this summer when the Pacific Northwest was scorched by a record-breaking “heat dome,” climate scientists were quickly able to determine that the event was made 150 times more likely due to climate change.

“Basically without climate change, this event would not have happened,”said Friederike Otto, a climate scientist at the University of Oxford, in an interview with Buzzfeed.

Such analyses would be relatively straightforward for many other climate-related impacts, Stuart-Smith explained, if plaintiffs knew to commission and use them. Combined with robust evidence from source attribution, those tools could help plaintiffs overcome the evidentiary hurdle needed to prove that oil and gas companies’ activities contributed to their economic losses.

Parenteau expressed optimism that the IPCC report’s high profile would remind lawyers of the importance of quality attribution science as they build their evidentiary cases. He’s paying attention to ongoing cases in California, where strong tort laws — a branch of laws that govern remedies for civil wrongs — could help cities like San Mateo and Oakland win cases against big polluters like Chevron.

“The real show is yet to come,” Parenteau said, “but you can be sure that the plaintiffs’ lawyers are well aware not only of the IPCC report itself, but of the contributing scientists and what their studies are showing.”

(AU ABC) Can The Antarctic Treaty Protect One Of The World's Last Great Wildernesses From Climate Change?

ABC Radio National | Sarah Scopelianos

Despite being extremely remote, Antarctica is facing many challenges exacerbated by human activity. (Supplied: Rodolfo Werner)

It's one of the world's last great wildernesses. Antarctica, the world's southernmost continent, is known for its penguins, polar expeditions and icy beauty.

But it's not quite as pristine as the brochures would like everyone to believe. Environmentalists say the region is facing multiple pressures from climate change, increased tourism and countries jostling for strategic positions.

And all that protects this majestic area is a single treaty, negotiated more than six decades ago.

So is the Antarctic Treaty robust enough to protect the 'Great White Continent'? Does it need to be updated? Or is it working as it should be?

Why have a treaty?

At its heart, the Antarctic Treaty is about keeping the peace.

Most land claims over Antarctica were made before World War II.

After the war, there was a renewed focus on polar research and something was needed to reduce the potential for conflict over Antarctica, says international law expert Donald Rothwell.

By the 1950s, seven nations — Argentina, Australia, Chile, France, New Zealand, Norway, and the United Kingdom — had claimed territorial sovereignty over areas of Antarctica.

And many others, including the United States and the Soviet Union, had been exploring the area.

"The treaty's genius was that it actually stopped those sovereignty and territorial disputes in the 50s, and during a critical period in the Cold War," Professor Rotherwell, from Australian National University, tells ABC RN's Counterpoint.

The treaty was signed in 1959 by 12 nations including Australia, United States and USSR and came into force on June 23, 1961.

While the treaty effectively neutralised territorial claims, Australia never relinquished the Australian Antarctic Territory, although this isn't recognised by many other nations.

The 5.9 million square kilometre area, equivalent to 80 per cent of the size of Australia, is about 42 per cent of the continent. And Australia has three research bases: Casey, Davis and Mawson.

Interestingly, the only piece of unclaimed land on Earth is in West Antarctica. The 1.6 million square kilometre section of icy terrain and glaciers, known as Marie Byrd Land, remains unclaimed due to its remoteness and lack of resources.

What's in the treaty?

The treaty bans military activities, nuclear testing and the disposal of radioactive waste in the region. It outlines a vision for peace and freedom of scientific research with nations cooperating and exchanging research plans and personnel.

There are also provisions for nations to inspect each other's ships, stations and equipment. Over the past 60 years, Australia has conducted 10 inspections in Antarctica — the most recent included visiting two facilities run by China and stops at bases run by Germany, Russia, Korea and Belarus last year.

Checks are usually to verify compliance with the environmental and non-militarisation principles of the treaty and to ensure scientific research is taking place.

Before the pandemic, there was an influx of tourists keen to spot Antarctica's wildlife. (Supplied: Rodolfo Werner)

Membership to the treaty has grown over time, with any member of the United Nations eligible to sign on. It now has 53 signatories but only 29 countries — either original signatories or those who are conducting substantial research on the continent — have voting rights to decide the continent's future, protection and enforcement of rules.

Decisions require consensus between the 29 nations.

Professor Rothwell says, by all standards the treaty is "very old".

"It has never been amended or modified [but] it's certainly been expanded."

He says that, in addition to the original treaty, there is a patchwork of agreements and protocols on issues like mining, management of protected areas, the environment, tourism, fishing and preservation of historical sites, which make up the Antarctic Treaty System.

"There's always been a bit of a question mark over it, in terms of whether it will remain good as a treaty regime into the future, given emerging geopolitical tensions," he says.

What are its successes?

Antarctic and Southern Ocean Coalition executive director Claire Christian says the treaty's mission to "permanently demilitarise an entire continent was a huge accomplishment".

"It was also quite important that the original signatories prioritised scientific research rather than economic exploitation," she says.

Christian says the addition of the Madrid Protocol in 1991 "refocussed" the treaty on environmental protection by banning mineral extraction. It also requires Antarctic Treaty parties to undertake environmental protection measures including environmental impact assessments and protected areas.

In some ways, Christian says, the protocol and the treaty are still "revolutionary" by prioritising environmental protection and international cooperation rather than national interests.

How is Antarctica faring?

Antarctic campaigner Alistair Allan, who has visited the region five times with the Sea Shepherd Conservation Society, says this part of the world faces serious challenges.

Climate change is the "absolute biggest threat" to the region. Allan, from the Bob Brown Foundation, points out that the 29 countries with voting rights over Antarctica are among the world's greatest emitters of greenhouse gases.

He believes these countries could make a real difference to the future of Antarctica — and the world.

He's calling for a "stronger shared care for the Antarctic environment" and for countries to make "real changes back at home".

Tourism is also a growing concern in the region. Before the coronavirus pandemic, there was a surge in cashed-up visitors all keen to explore the continent.

"When they wrote the treaty, that wasn't even a thing. There was no anticipation for the biggest industry in Antarctica to be tourism," Allan says.

Increased visitors put further pressure on the ecosystem with more ship and aircraft movement, more people on the ground exploring sensitive areas like penguin rookeries and the potential for invasive species to be introduced.

"Every little activity by itself doesn't necessarily harm the environment," Allan says, but adds that it all has a cumulative impact.

Climate change and increased human activity are just some of the challenges Antarctica faces.(Supplied: Rodolfo Werner)

Is the treaty working?

It depends on who you ask.

Professor Rothwell says at face value the treaty is achieving its aim.

Humans have accessed more than two-thirds of the Antarctica and the proportion of places not impacted by people is shrinking, say researchers who are calling for greater protection of wilderness areas. Read more


"It's not only holding the peace but it's keeping scientific research going, which has always been critical on the continent," he says.

"The scientific research has evolved to have an increasing focus on climate change, so you can't say that the research is not relevant and contemporary and focussed."

Allan isn't so sure. He describes an atmosphere akin to a "moon race" between countries "jostling for territory" by proposing large infrastructure projects.

For instance, Australia has plans to build a 2.7 kilometre concrete airstrip to receive planes all year round.

Allan says the project near Davis Station is an example of a country trying to shore up its territorial claim.

"Due to climate change, the ice runway in summer is actually melting and they can't land the planes ... but the real reason is about huge strategic imperatives," he says.

What needs to be fixed?

Both Allan and Christian agree the treaty's core is solid but there are weaknesses.

"There are plenty of scientists and government officials who understand what needs to be done [to protect the region] and have good ideas for implementing it but they are too often blocked by one or two countries," Christian says.

Enforcement of the rules is another issue.

For instance, when South Korean and Russian fishing vessels were caught fishing illegally in the area, they avoided the consequences after their respective countries couldn't agree on how to enforce the regulations.

Allan says there needs to be stricter regulations and more countries involved in making decisions.

"The foundation is strong in terms of no-military, cooperation, natural reserve, peace and science ... What it needs now is stricter control regulation and potentially also bringing more people into that conversation.

"At the moment, it is still the 29 voting countries that primarily get to choose what happens and there's not much say from the rest of the world.

"What happens in Antarctica affects all of us."

(AU Pearls and Irritations) Climate Change: Will The Financial System Survive?

 Pearls and Irritations - Ian Dunlop | David Spratt

One of the few bright spots in an otherwise dismal global response to the escalating climate crisis has been the preparedness of financial market regulators to force their regulated institutions to face up to the implications of climate risk.



Authors
  • Ian Dunlop was formerly an international oil, gas and coal industry executive, chair of the Australian Coal Association and CEO of the Australian Institute of Company Directors. He is a member of the Club of Rome and Chair, Advisory Board, Breakthrough National Centre for Climate Restoration.
  • David Spratt has been Research Coordinator for the Breakthrough National Centre for Climate Restoration (Melbourne) since 2014. He was co-founder of the Climate Action Centre (2009-2012). He blogs at climatecodered.org on climate science, existential risk, IPCC reticence, the climate emergency and climate movement strategy and communications, and is regular public speaker.
In so doing, they have been acutely aware of the lessons learnt from the 2008 Global Financial Crisis, where scenario analysis, expert financial modelling and stress testing failed to foresee the crisis and the consequences for the banking system, investors and business alike.

As a result, the global financial system was only saved from collapse by a massive trillion-dollar bailout, for which the banks and corporations who caused it have yet to be held accountable.

When questioned by the Queen in 2008 as to why the crisis had occurred, the British Academy, after much introspection, responded that a “psychology of denial”  led to “the failure of the collective imagination of many bright people … to understand the risks to the (financial) system as a whole.”

The reaction to the ominous warnings in the first part of the  Intergovernmental Panel on Climate Change’s (IPCC) 6th Assessment Report, recently released, demonstrates that the same psychology of denial is alive and well, particularly in Australia.

The financial press has erupted with ever-more incredulous claims as to why gas, oil, and even coal are absolutely essential to solving the climate crisis.

Politicians are suddenly experts in silver bullet technologies that will solve our problem without understanding the limitations of their claims, and trawl the web even more vigorously than normal for any sliver of denialist evidence that the climate issue might just go away.

Fortunately, regulators with independent mandates to ensure the stability of the global financial system are taking their responsibilities seriously. To make climate risks more transparent, central banks and regulators globally are stress-testing the financial system.

Most notable have been initiatives by the Task Force on Climate-related Financial Disclosures (TCFD), the European Central Bank (ECB) and the scenario work of the Network for the Greening of the Financial System (NGFS).

In Australia, regulators have coordinated their work through the Council for Financial Regulators, with the Australian Prudential Regulatory Authority (APRA) initiating a climate vulnerability assessment for banks, encompassing scenarios up to 3°C of global mean warming, and issuing draft guidance for companies to stress test their own finances against scenarios up to 4°C warming.

Stress tests are simulations, relying on scenarios of future circumstances, and on models of the climate, the economy and the financial system. These techniques are valuable in reasonably well-understood circumstances, but they have severe limitations in addressing the threats that climate change now presents.

The latest IPCC report has begun to discuss these issues, which include non-linear processes such as climate tipping points, cascade effects and radical uncertainty, where probabilities cannot be attached to specific outcomes, but even now the IPCC remain relatively reticent on these potentially existential, but increasingly possible, threats.

It is particularly challenging to map first-order physical climate warming impacts onto the second-order impacts in the social and financial spheres because it depends on the responses of complex human systems which cannot be reduced to probabilistic terms.

In a complex world, systemic risks can arise from interactions between changes in the physical climate and human systems, so that small changes can lead to large divergences in the future state of human society.

Scenario analysis creates coherent, credible stories about alternative futures, allowing for constructive discussion on alternatives that should take into account the full range of credible evidence. But too often it is devalued and represents little more than sensitivities around some conventional strategic plans.

Scenarios, properly used, can assist in securing a safe and stable future, but only if applied with brutal honesty in exploring extremes and not just a predetermined path.

Unfortunately, global leaders, and Australia’s in particular, have not acted fast enough to avoid locking in extremely dangerous, and potentially catastrophic, climate impacts.

Those impacts are close to moving beyond human control as global warming accelerates, evidence of which was clearly seen with the unprecedented 2019-20 Australian and Californian bushfires, the Chinese floods and Indian extreme temperatures. 

Even greater extremes are occurring in recent weeks in the Western USA, Canada, the Arctic, Siberia, Europe, China and the Amazon, resulting in some impacts that were not projected until around 2100.

In that context, the approach currently being used by regulators in assessing the future assumes compliance with the Paris Climate Agreement, unsustainable economic growth, reliance on technologies not yet proven or deployed at scale, an overshoot of the Paris temperature target, and a big continuing role for gas.

This worldview is being rapidly overtaken by events.

Scientists and analysts consider 4°C of warming to be an existential threat, incompatible with the maintenance of human civilisation, and 3°C to be catastrophic, perhaps leading to outright chaos in the relations between nations. 

Applying stress tests to such circumstances is problematic. Even at 3°C, the impacts may be so great as to be potentially infinite and unquantifiable, making scenario testing largely irrelevant.

It is unlikely that the banking system could survive such levels of warming, as discussed in our latest report: “Degrees of Risk: can the banking system survive climate warming of 3oC?”

Markets crave stability, but the world is entering an era of instability and uncertainty driven, inter alia, by climate-related financial risks. This makes the current approaches to managing these risks not fit-for-purpose.

Sensible risk management, especially for highly uncertain events such as we are now facing, demands a precautionary approach, which must be applied to prevent these risks from materialising.

Such precautionary action must ensure temperature outcomes do not trigger further tipping points or cascading effects which move the climate system beyond human influence and are capable of returning it to the stable climate conditions under which human civilisation flourished.

This means emergency action to keep the temperature increase to a minimum, as close to 1.5°C as possible, coupled with the drawdown of current atmospheric carbon concentrations.

If the financial system is to survive and prosper, reactive disclosure of risks alone is no longer enough; time is short and mitigating those risks must become the absolute focus of regulators and regulated alike.

Company directors have a fiduciary responsibility to identify the risks to which their organisations are exposed, and to implement suitable systems to manage those risks. 

In the context of climate risk, boards of directors have too readily adopted recommendations from regulators and from supranational organisations such as the International Energy Agency or the IPCC, without bothering to understand the limitations of such analysis, thereby failing in their fiduciary responsibility to fully assess risk.

Regulators, here and overseas, exert great influence over financial and corporate players. If climate risk regulators imply warming of 3-4oC is manageable or can be adapted to, and such thinking becomes enshrined in the corporate psyche, as is currently happening, then regulators will be institutionalising failure, which is certainly not their intent.

Instead, regulators must now demand that the regulated proactively disclose what emergency precautionary action they are taking to ensure the world remains as close to a 1.5oC global mean temperature increase as possible.

This is just one change amongst many that must occur if humanity is to survive and prosper through the 21st Century and beyond.

And it is an important one because we cannot afford another failure of imagination.

(The Conversation) Seemingly Small Climate Changes Can Have Big Consequences

Climate change has been accumulating slowly but relentlessly for decades.

The changes might sound small when you hear about them – another tenth of a degree warmer, another centimeter of sea level rise – but seemingly small changes can have big effects on the world around us, especially regionally.

The problem is that while effects are small at any time, they accumulate. Those effects have now accumulated to the point where their influence is contributing to damaging heat waves, drought and rainfall extremes that can’t be ignored.

The most recent report from the United Nations’ Intergovernmental Panel on Climate Change is more emphatic than ever: Climate change, caused by human activities like burning fossil fuels, is having damaging effects on the climate as we know it, and those effects are rapidly getting worse.

Earth’s energy imbalance

An excellent example of how climate change accumulates is Earth’s energy imbalance. I am a climate scientist and have a new book on this about to be published by Cambridge University Press.

The Sun bombards Earth with a constant stream of about 173,600 terawatts (that is 12 zeros) of energy in the form of solar radiation. About 30% of that energy is reflected back into space by clouds and reflective surfaces, like ice and snow, leaving 122,100 terawatts to drive all the weather and climate systems around us, including the water cycle. Almost all of that energy cycles back to space – except for about 460 TW.

That remaining 460 TW is the problem we’re facing. That excess energy, trapped by greenhouse gases in the atmosphere, is heating up the planet. That is the Earth’s energy imbalance, or in other words, global warming.

Outgoing radiation is decreasing, owing to increasing greenhouse gases in the atmosphere, and leading to Earth’s energy imbalance of 460 terawatts. The percentage going into each domain is indicated. Kevin Trenberth, CC BY-ND

In comparison with the natural flow of energy through the climate system, 460 TW seems small – it’s only a fraction of 1 percent. Consequently, we cannot go outside and feel the extra energy. But the heat accumulates, and it is now having consequences.

To put that in perspective, the total amount of electricity generated worldwide in 2018 was about 2.6 TW. If you look at all energy used around the world, including for heat, industry and vehicles, it’s about 19.5 TW. Earth’s energy imbalance is huge in comparison.

Interfering with the natural flow of energy through the climate system is where humans make their mark. By burning fossil fuels, cutting down forests and releasing greenhouse gases in other ways, humans are sending gases like carbon dioxide and methane into the atmosphere that trap more of that incoming energy rather than letting it radiate back out.

Before the first industries began burning large amounts of fossil fuels in the 1800s, the amount of carbon dioxide in the atmosphere was estimated at around 280 parts per million of volume. In 1958, when Dave Keeling began measuring atmospheric concentrations at Mauna Loa in Hawaii, that level was 310 parts per million. Today, those values have climbed to about 415 parts per million, a 48% increase.

Carbon dioxide is a greenhouse gas, and increased amounts cause heating. In this case, the human increment is not small.

Where does the extra energy go?

Measurements over time show that over 90% of this extra energy is going into the oceans, where it causes the water to expand and sea level to rise.

The upper layer of the oceans started warming around the 1970s. By the early 1990s, heat was reaching 500 to 1,000 meters (1,640 to 3,280 feet) deep. By 2005, it was heating the ocean below 1,500 meters (nearly 5,000 feet).

The average global temperature change at different ocean depths, in zetajoules, from 1958 to 2020. The top chart shows the upper 2,000 meters (6,561 feet) compared with the 1981-2010 average. The bottom shows the increase at different depths. Reds are warmer than average, blues are cooler. Cheng et al, 2021, CC BY-ND

Global sea level, measured by flights and satellites, was rising at a rate of about 3 millimeters per year from 1992 to 2012. Since then, it been increasing at about 4 millimeters a year. In 29 years, it has risen over 90 millimeters (3.5 inches).

If 3.5 inches doesn’t sound like much, talk to the coastal communities that exist a few feet above sea level. In some regions, these effects have led to chronic sunny day flooding during high tides, like Miami, San Francisco and Venice, Italy. Coastal storm surges are higher and much more destructive, especially from hurricanes. It’s an existential threat to some low-lying island nations and a growing expense for U.S. coastal cities.

Some of that extra energy, about 13 terawatts, goes into melting ice. Arctic sea ice in summer has decreased by over 40% since 1979. Some excess energy melts land ice, such as glaciers and permafrost on Greenland, Antarctica, which puts more water into the ocean and contributes to sea level rise.

Some energy penetrates into land, about 14 TW. But as long as land is wet, a lot of energy cycles into evapotranspiration – evaporation and transpiration in plants – which moistens the atmosphere and fuels weather systems. It is when there is a drought or during the dry season that effects accumulate on land, through drying and wilting of plants, raising temperatures and greatly increasing risk of heat waves and wildfire.

Consequences of more heat

Over oceans, the extra heat provides a tremendous resource of moisture for the atmosphere. That becomes latent heat in storms that supersizes hurricanes and rainstorms, leading to flooding, as people in many parts of the world have experienced in recent months.

Air can contain about 4% more moisture for every 1 degree Fahrenheit (0.55 Celsius) increase in temperature, and air above the oceans is some 5% to 15% moister than it was prior to 1970. Hence, about a 10% increase in heavy rain results as storms gather the excess moisture.

Again, this may not sound like much, but that increase enlivens the updrafts and the storms, and then the storm lasts longer, so suddenly there is a 30% increase in the rainfall, as has been documented in several cases of major flooding.

In Mediterranean climates, characterized by long, dry summers, such as in California, eastern Australia and around the Mediterranean, the wildfire risk grows, and fires can be readily triggered by natural sources, like dry lightning, or human causes.

Extreme events in weather have always occurred, but human influences are now pushing them outside their previous limits.

The straw that breaks the camel’s back syndrome

So, while all weather events are driven by natural influences, the impacts are greatly magnified by human-induced climate change. Hurricanes cross thresholds, levees break and floods run amok. Elsewhere, fires burn out of control, things break and people die.

I call it “The straw that breaks the camel’s back syndrome.” This is extreme nonlinearity, meaning the risks aren’t rising in a straight line – they’re rising much faster, and it confounds economists who have greatly underestimated the costs of human-induced climate change.

The result has been far too little action both in slowing and stopping the problems, and in planning for impacts and building resilience – despite years of warnings from scientists. The lack of adequate planning means we all suffer the consequences.
