An Optimist's Guide To Solving Climate Change And Saving The World

VICEGeoff Dembicki*

We asked experts what policies they would put in place to fight climate change and got some unexpected answers.


Imagine, for a second, that the debate on climate change is over. Donald Trump is no longer president, of course. The political and economic influence of the fossil fuel industry is in freefall, climate change denial is an absurdity from the past that only your grandparents still talk about, and every political and business leader on the planet has made slowing global temperature rise their single most important goal. What would it be like to live in that world?
Probably your mental landscape includes more solar panels and wind turbines, highways full of electric cars, energy-efficient buildings, the replacing of dirty fuels with less damaging alternatives. If that’s the case, you could be ignoring a huge part of the solution. Cleaner technology is essential if we are to have any kind of long-term future. But it’s only one piece of a transition with potential to restructure our planet-ravaging economic system and the toxic politics the system has created. Unbeknownst to most people, even those who follow climate change closely, this transition is already underway.
Over the past few weeks I have had long and unguarded conversations with experts who don’t see themselves as traditional environmental thinkers, yet are on the leading edge of efforts to address the most serious crisis civilization has ever faced. I asked them to describe a world where their solutions are being implemented at the highest levels of our political and economic order. And though their answers were as diverse as their backgrounds, they agreed that the future we must build to stave off environmental collapse may well be more prosperous, equitable, and democratic than the world we currently live in. That’s the good news.
But they warned me that if we mismanage this transition, if we don’t adhere to certain fundamental truths, we risk creating a society every bit as unequal and exploitative as the one we currently live in.



Examples of our shift away from nature-destroying activities are everywhere. There is the California town of Richmond suing Chevron, its biggest employer, for helping to cause climate change. There’s the Lubicon Lake Band installing solar panels in the heart of Canada’s tar sands. and the Los Angeles battery-storage company that’s investing $400 million in Appalachian coal country. Zoom out and view these stories in aggregate and their impact is staggering. Researchers with the London School of Economics calculated one in ten US workers are helping build the green economy. London-based analysts FTSE Russell have estimated the global green economy to be worth $4 trillion, which is comparable to the oil and gas sector.
“We can build something better than we had before by moving off of fossil fuels,” May Boeve, the head of the climate advocacy group 350.org, told me.
Stories about climate change rarely dominate the news cycle. And in the Donald Trump era they’ve been pushed further to the margins. Much news coverage of this year’s G7 summit meeting in Quebec, for example, focussed on the personal feud between Trump and Canadian Prime Minister Justin Trudeau. Yet a communiqué released by the summit, which Trump refused to endorse, suggested that future economic progress is inseparable from climate action. “This is something greens have been demanding for years: climate change at the core of global geopolitics,” meteorologist and Grist climate columnist Eric Holthaus wrote in the wake of that summit. “Now it’s here.”
We’re still very far from where we need to be. A paper this June in Nature Energy estimated the world must invest an additional $460 billion per year in climate solutions over 12 years to have any hopes of hitting 1.5 degrees. Any warming beyond that target, which is looking less and less achievable, drastically increases humankind’s exposure to deadly heat waves, flooding, diseases, drought, and famine. Yet that doesn’t mean we’re charging headfirst to civilizational collapse.
“The kind of chaos that most apocalyptic visions describe… like, ‘We’re going to have gunboats in the harbors shooting refugees,’ that kind of stuff rarely recognizes how bad that would be for capitalism,” Geoff Mann, co-author of Climate Leviathan, a new book explaining how geopolitics could evolve in response to climate change, told me. “All the most powerful states are tied very tightly to the health of the global capitalist system and they’re not just going to throw that up and forget about it.”

Instead, as the impacts of climate change grow more destabilizing, business leaders are likely to push politicians to mount an aggressive response. The pressure Mann describes is already building. Last year, Apple, Google, Facebook, Microsoft and 21 other companies placed a full-page ad in the New York Times, Wall Street Journal, and New York Post urging Trump to keep the US in the Paris climate agreement, arguing “climate change presents both business risks and business opportunities.” (Trump ignored this plea.) Earlier this year, the World Economic Forum, which hosts an annual meeting in Davos, Switzerland, bringing together thousands of CEOs, world leaders, celebrities and economists, warned that “the world needs to move faster on climate change to avoid disaster.”
Mann predicts we could someday see the emergence of a global authority representing the interests of powerful countries and corporations that would help coordinate and enforce drastic climate actions around the world. This world would be much more sustainable than today’s but also has the potential to be massively unequal. Which is why Mann argues that “we have to ensure this transition doesn’t lock in existing injustices or inequalities even more than it already does.”The time to do so is dwindling. People with the least responsibility for climate change, like the Filipino typhoon survivors I met last year for VICE, are already suffering more than the wealthy people who caused it. Yet everyone I spoke to for this story thinks a planetary transition guided by the desires and experience of communities on the frontlines of climate change is still possible. Here’s what it could look like:

Mass Affordable Housing
Humans need a place to live and a means of transporting themselves. Yet the way our society provides these necessities is terrible for climate change. Many people live in inefficiently designed buildings and get around in gas-powered cars. These two things—buildings and transportation—represent more than one-third of US carbon emissions. For years we’ve treated this as mainly a technological problem to be solved by designers, architects and businesspeople. In Vancouver, Canada, where I live, a developer named Westbank is building a 43-story housing tower that is certified as LEED Gold, one of the highest standards for sustainability. It has dozens of electric vehicle charging stations. Studio apartments start at $1 million.
What if we treated the climate impact of buildings and transportation as a social challenge instead of an engineering challenge? California offers an interesting case study. Over the past decade or so the state has passed some of the world’s most ambitious climate legislation. Yet more and more people are getting around in private cars. Several years ago Vien Truong, an organizer from West Oakland, met with people living in lower-income communities to learn what they need to become more sustainable. Near the top of their list was affordable housing. California’s rapidly increasing housing costs have pushed lower-income people to the edges of cities, far from public transportation. “This is why you always want to talk to community members first,” she told me.
In 2012, Truong helped pass a law that redirects one-quarter of the revenue raised by cap and trade in California (a program that makes polluters pay for emitting carbon) to communities left out of the state’s economic boom. To date, that adds up to more than $800 million. Affordable housing near transit is a funding priority. “It wasn’t just an environmental policy,” said Truong, who is now head of Dream Corps, a social justice organization started by former Barack Obama advisor Van Jones. “It was a way of designing policy that supports healthy, whole, and safe communities.” She has since spoken to policymakers around the world about the experience. “Absolutely I do think it’s a model we can replicate,” Truong argued.

More Education for Girls
Many people’s image of progress on climate change involves a room full of world leaders in expensive suits signing a densely-worded treaty. But progress can also look like a classroom of children. When environmental researcher and author Paul Hawken set out to rank the 100 most effective solutions to climate change, he put expanding access to education for girls living in lower-income countries at number six. Women with more education have fewer children, which reduces stress on the planet’s resources. They also tend to earn more money and contribute to stronger communities. Hawken estimated this could help cause a 60-gigaton drop in global emissions. That’s roughly equivalent to removing 340 million cars from the road.
Melina Laboucan-Massimo, a member of the Lubicon Cree First Nation in Northern Alberta, as well as a Climate Change Fellow at the David Suzuki Foundation, has seen firsthand the transformative impact of education. Her hometown of Little Buffalo is at the center of Canada’s tar sands. In 2013, a pipeline broke and spilled 28,000 barrels of oil near the community. Horrified, she decided to lead an effort to install 80 solar panels in Little Buffalo. “It was the first time ever that solar panels were seen in our community,” she told me. When she spoke about the project with local indigenous elementary school students, “You could just see within their questioning that they were really excited,” Laboucon-Massimo recalled. “They had really started thinking about, ‘Oh these solar panels help us not burn fossil fuels.’” The children will now grow up knowing a future without oil, gas, and coal is possible.

No More Climate Denial
Much of the technology for a low-carbon shift already exists. States and cities that have embraced it are thriving economically. Yet making that shift a core priority of the US federal government is right now politically impossible. Last year, some conservative thinkers argued in the New York Times that the GOP should support a policy of taxing carbon emissions and then returning the revenues to people as tax refunds. This was not embraced by the Republican Party as a whole, however—Breitbart advised them to “shove their carbon tax.” Most Republican leaders still deny humans are at fault for climate change. In the past year, the number of GOP supporters who acknowledge humans are causing it shrunk from 40 to 35 percent, according to a Gallup poll that found up to 90 percent of Democrats accept the science.
Years of academic research into polarization on climate have yielded a relatively straightforward insight: Ordinary people reject climate science and the solutions associated with it because right-wing thought leaders such as Rush Limbaugh urge them to do so. “It’s not like Joe Schmo in suburban St. Louis has a ton of intrinsic, deeply felt, idiosyncratic opinions about the effect of CO2 in the atmosphere,” David Roberts, the lead climate columnist at Vox, who has written extensively on political polarization, told me. “He opposes the climate change hoax bullshit because that’s what the people he respects on talk radio tell him is what conservatives believe.”

If Republicans such as Trump and Mitch McConnell suddenly started believing in climate change, many conservative Americans might also shift their opinion. But how could you flip right-wing elites? One pathway there could be for a Democratic administration to deliberately shrink the market share of fossil fuel companies. “I would ban gasoline and diesel vehicles by 2035,” Roberts said. “People would freak out, but the minute it became law there would be this outburst of innovation.” New industries would align behind the low-carbon transition and begin to lobby Washington. And fossil fuel companies who have helped to push Republicans to deny the scientific consensus on climate change would lose influence. Once that happened, climate denial could conceivably start to fade from national politics.
This might accelerate state-level action. In places like Texas, much of the work to make farming more drought-resistant, shift to clean energy, and otherwise adapt to a warmer planet is being done by people skeptical of the science, Katharine Hayhoe, an evangelical Christian and a climate scientist at Texas Tech University, told me. Yet it’s not occurring near fast enough to keep climate change from throttling the region. If deniers now governing states like Texas, Louisiana, and Florida accepted scientific reality, “it would completely change the tone of the conversation,” Hayhoe argued. “You’re adding a recognition of urgency… If you don’t acknowledge humans are changing the climate, then you don’t acknowledge that it’s going to get worse.”

Stronger Democracy
There is no scenario for addressing climate change that does not involve a rapid global build-out of clean energy. This piece of our world’s low-carbon shift is worth big money. Over $330 billion was invested in technologies such as wind and solar last year. Renewables directly employ nearly 10 million people. Tech corporations like Amazon are making clean energy commitments. The market for electric cars shows signs of exploding. The scenario Mann described earlier in this piece, where clean energy elites lead an aggressive capitalist response to climate change, seems more likely every year. Yet alongside it is the potential for a mass revitalization of local democracy.
When several dozen academics, diplomats, and energy experts gathered last year in Berlin to imagine what the world would be like if most of its energy came from renewables instead of fossil fuels, they came to the conclusion that this future may “become increasingly regionalized and localized.”
“Citizens who provide for their own energy and have increased access to education, health and wealth independently of government programs may feel emboldened to ask for more political participation or in some extreme cases, even promote secessionist tendencies,” they wrote. Decentralized renewable energy could someday provide electricity to millions of people who are currently lacking it. “You’re talking about a whole generation who know their experience of turning on the lights as not being connected to a coal grid very far away that’s making somebody rich,” Boeve from 350.org said. “But that’s actually in their own community, that they help control.”
The experience of being able to generate your own power is already influencing politics within the US. When fossil fuel utilities in Florida backed a measure that would increase fees on users of rooftop solar, Debbie Dooley, a Trump-supporting Tea Party activist and renewable energy advocate, helped bring together Christians, libertarians, business groups, and environmentalists in opposition to the fee increase—and they won. Dooley told me rooftop solar appeals to people across the political spectrum because it increases freedom. “I just see a day where everybody powers their own home,” she said. “Individual liberty is what it comes down to.”

The Path Forward
Trump is so bad for climate change that just about anyone who takes the crisis seriously looks great by comparison. These days that person is likely to be a tech billionaire. “Climate change is the biggest threat that humanity faces this century, except for AI,” Elon Musk told Rolling Stone. We need people like Musk to throw their financial and technological weight into solutions. Yet there have been reports of poor safety conditions, low wages, and anti-union intimidation at the Tesla factory in Fremont, California. “Everything feels like the future but us,” one worker explained to the Guardian.
“It’s tempting to imagine that men like Elon Musk can save the planet for us, that we just need to unleash the power of their innovation and wait for the magic,” Naomi Klein and Avi Lewis wrote last year in The Nation. “But as the workers in Fremont well know, the quest for profit very often comes at the expense of people—even when the product is green.”When the future isn’t perceived as fair, when it means large sections of society struggling to get by in a warmer world while a techno-elite calls all the shots, that provides authoritarian leaders with the chance to exploit people’s anger. We saw it with Trump in coal country. And we will keep seeing it, the experts I spoke with for this story said, so long as the desires of vulnerable communities are ignored.
“We need to have a climate justice league that’s made up of both policymakers and scientists but also everyday folks who are dealing with some of these challenges,” Mustafa Santiago Ali, a former senior advisor at the US Environmental Protection Agency who now helps lead a social justice group known as the Hip Hop Caucus, told me. “We’ve got to be smarter moving forward,” he said. “We have lots of work to do.”

States Combine To Pressure Turnbull On Climate Target

FairfaxDavid Crowe | Cole Latimer

The Turnbull government is facing new demands to give ground on the climate change target that underpins its National Energy Guarantee, as Labor states negotiate a joint position to force changes to the scheme at a crucial meeting next week.
Labor governments in Victoria, Queensland and the ACT are brokering a new list of demands to be unveiled next week to ensure a future federal government has more scope to make deeper cuts to greenhouse gas emissions over the decade ahead.
With the federal policy hanging in the balance, the united stance is aimed at maximising pressure on Energy Minister Josh Frydenberg to go much further than his latest proposal for a review of the target in 2024.

The state negotiations are influenced by calls from environmental and business groups for greater flexibility in the way the federal government adjusts the target, including a hotly contested proposal to increase it without needing legislation.
Mr Frydenberg revealed the 2024 review as a concession to the states last week but critics have rejected it as meaningless because the terms of reference are not clear and the states have no input into its conduct.
A key sticking point is that there is no stated mechanism in the federal plan to act on the review and increase the government’s commitment to reduce emissions by 26 per cent by 2030 – a target federal Labor wants to increase to 45 per cent.
“The target-setting process is where all the action will be,” said one source.
Fairfax Media has been told Victorian Premier Daniel Andrews and Energy Minister Lily D’Ambrosio are preparing to formalise their negotiating position early next week at cabinet level, while also discussing the joint position with Queensland and the ACT.
The moves come after the government released a final report from the Energy Security Board, the group of Australia’s peak energy regulators, on the case for the new scheme including some of the modelling behind claims of a cut to household bills.
“Stakeholders have been clear with the Energy Security Board that the status quo is simply not acceptable,” said Kerry Schott, the chair of the board, in a message to the states and territories.
“Any delay, or worse a failure to reach agreement, will simply prolong the current investment uncertainty and deny customers more affordable energy."
Dr Schott reiterated the key finding that the average household bill is expected to be $550 lower each year during the 2020s than it is now - $150 of those savings coming from the NEG.
But the report triggered a furious response from some jurisdictions over the modelling, with officials complaining that the document did not contain all the key assumptions behind the claims of a cut to household bills.
Queensland Energy Minister Anthony Lynham has joined Ms D’Ambrosio in expressing concern that the states and territories are being asked to endorse the NEG on August 10, before its support among federal Coalition MPs is tested at a party room meeting in Canberra on August 14.
While the timing dispute focuses on the process to agree on the NEG, the states are still canvassing the matters of substance to demand at the meeting next week, including the rules around the emission targets.
In an influential submission, the Australian Industry Group has called for federal law to set out the terms for the emissions review and allow a future government to amend the 26 per cent target using subordinate legislation.
The business group calls for the law to state explicitly that the review should have regard to Australia’s international commitments at the United Nations, such as the Paris climate change targets.
Ai Group also calls for the review to consider the economy-wide task of reducing emissions – the key problem of whether the NEG should do more to reduce emissions in electricity to spare the burden on farming and other sectors.
Fairfax Media revealed last week that Mr Frydenberg was holding out against calls to use regulation or subordinate legislation to amend the 26 per cent target, given the risk of a revolt from former prime minister Tony Abbott and others over the idea of delegating the change to a minister rather than the parliament.Environment Victoria senior energy adviser Erwin Jackson said the “rules of the game” should be defined up-front by the Turnbull government so all sides knew how the target could be changed.
“Governments must have the ability to change the targets in a timely way. The 2024 review of emissions targets is in the never-never, and would stall clean energy investment,” he said.
“The rules that need to be defined in the federal legislation to change the target include explicitly stating that the minister must consider Australia has committed to ensuring national targets are stronger through time, changes in technology, and the impact of the target on other sectors and vulnerable households and communities.”
Mr Frydenberg reiterated that the Commonwealth was responsible for the emissions reduction target and would conduct the review to make sure the target remained “appropriate” over the period from 2025 to 2030.
“The review will include public consultation and a report of the review will be published by 30 June 2024,” he said.
While the government remains confident of securing support from a majority of Coalition MPs for the NEG, former prime minister Tony Abbott rubbished the latest report and the modelling that claimed a cut to household bills.
“Well, frankly pigs might fly. This is just wrong,” Mr Abbott told radio station 2GB, adding that renewable energy was not reliable enough.
Grattan Institute energy director Tony Wood said the modelling confirmed earlier advice from the Energy Security Board with some clarity around the assumptions.
“The NEG doesn’t really reduce emissions much by 2030, and if you add the effect of the Victorian Renewable Energy Target and Queensland Renewable Energy Target, it would be even less,” Mr Wood told Fairfax Media.
“For example, without the NEG, renewables will be 34 per cent of the energy mix by 2030 and with the NEG only 36 per cent.
“The real point is that the NEG provides a consistent platform for what will be serious emissions targets later while ensuring that reliability is not adversely affected.”
Ed McManus, the head of generator Meridian Energy and retailer Powershop, said industry was behind the NEG as there was little alternative.
“We’re in the camp of something is better than nothing, and that’s what this policy is,” Mr McManus told Fairfax Media.
“As long as the targets can be increased relatively easily if a later government decides it wants to, we support it, as we think the energy sector should have higher emissions reduction targets.
“The policy itself will work, as long as it is in a form that allows these targets to be increased.”

Scientists Warn Intensity Of Australian Storms Has More Than Doubled And Could Get Worse

NEWS.com.au - Stephanie Bedo

SHORT but intense thunderstorms are increasing at a rate much higher than expected — now experts warn we should brace for even worse rain extremes.

SCIENTISTS have been “severely underestimating” our short thunderstorms which are actually set to get worse.
The latest rainfall research on Australia reveals how heavy and quick rain storms are intensifying more rapidly than expected.
This means more flash floods, severe water surges in urban areas and bigger dry and wet extremes in general.
A team of international scientists, led by Newcastle University in the UK and involving the University of Adelaide, studied intense rain storms in Australia over the past 50 years and discovered they were substantially larger than anticipated under climate change.
They found the amount of water falling in thunderstorms is increasing at a rate two to three times higher than expected, with the most extreme events showing the biggest increases.

Associate Professor Seth Westra, of the University of Adelaide, warned this meant we were poised for worse problems.
“This large increase has implications for the frequency and severity of flash floods, particularly if the rate stays the same into the future,” Associate Professor Westra said.
“It seems counter intuitive when large parts of Australia are now in drought, but we need to remember Australian droughts are often broken by severe floods.
“We have always been a country of weather extremes, and it seems that climate change is causing both the dry and wet extremes to intensify.”
A devastating dry spell is affecting 99 per cent of New South Wales.
Below average rainfall since April 2017 has been exacerbated by warm, dry weather, according to the Bureau of Meteorology.
September 2017 was the driest September on record, compared with the previous year, which was the wettest September.
Two-thirds of Queensland and farmers in parts of Victoria, South Australia and Western Australia are also suffering.
Experts have warned shoppers could soon feel the pinch at the checkout as our drought crisis deepens.
While daily extremes can cause river flooding, hourly and multi-hourly extremes often cause urban flooding in small, steep rivers, and landslides.
The study in Nature Climate Change showed that the situation was worse in the tropical north where researchers expected an increase in severity of seven per cent but returned a “highly concerning” 20 per cent.

Lead author Dr Selma Guerreiro, of the UK, said scientists believed there was a limit on how much more rain could fall during extreme events because of rising temperatures but now that upper limit had been broken.
“The important thing now is to understand why rainfall is becoming so much more intense in Australia and to look at changes in other places around the world,” Dr Guerreiro said.
“How these rainfall events will change in the future will vary from place to place and depend on local conditions besides temperature increases.”
Associate Professor Westra said the changes were well above what engineers currently took into account when determining Australia’s flood planning levels or designing stormwater management and flood defence infrastructure.
“If we keep seeing this rate of change, we risk committing future generations to levels of flood risk that are unacceptable by today’s standards,” he said.
The analysis was based on looking at rainfall extremes between 1990-2013 and 1966-1989, from 107 weather stations from all over Australia.

Adapt Or Perish: UK Leads The Way In Protecting Citizens Against Climate Change

ABC - Dr David Shearman*

To the World Health Organisation, climate change is the greatest health threat of this century. (Reuters: Liu Chang)
Despite the distraction and political chaos of Brexit negotiations, the United Kingdom has just published a far-reaching and thoroughly impressive plan to manage risks from climate change.
This follows on from their broader 25-year Environment Plan, released in January. It aims to "help the natural world regain and retain good health", to enable it to better cope with climate change.
The recently released climate plan is a strategy to save lives from heat, flood and fire — yes, fire, even in the UK!
It should be compulsory reading for the Australian Government, because we have no such plan. Considering the lives that will be lost, this is negligence in medical terms.
And as a doctor, it concerns me greatly: all doctors recognise the vital need for adaptation to manage the growing health risks of climate change.


Be prepared for the heat
Heatwaves kill far more people than other natural disasters. ABC Emergency has a checklist of things you can do to be ready.

'We've stood still for 20 years'
Global efforts to mitigate climate change are tokenistic given the size of the problem. Fossil fuels continue to burn our future; in Australia, over 80 per cent of electricity comes from fossil fuel.
"Despite the extraordinary growth in renewables in recent years," writes BP's chief economist Spencer Dale, "there has been almost no improvement in the power sector fuel mix over the past 20 years.
"The share of coal in 1998 was 38 per cent — exactly the same as in 2017. We have stood still for 20 years."
The UK has got the message that current emission reduction efforts are inadequate to prevent coming disasters and priority must be given to protecting the public. They recognise that human health depends on environmental health.

What's the UK doing?
The UK's 2008 Climate Change Act obliges the government to have policies to adapt to climate change.
The Government must publish a climate change risk assessment every five years, based on scientific information from the Climate Change Committee. This assesses the risks for flooding, heat, drought, food, pests and natural capital risks. For example, 7,000 heat-related deaths are expected every year in the UK by 2050 — triple the current rate.
The climate change adaptation plan anticipates water shortages for agriculture, energy generation and industry. In response, it plans to increase water supply and drive greater water efficiency.
The climate adaptation plan also highlights strategies already underway in public services.
The NHS, for example, plans to embed adaptation into daily practice by 2023.

The forgotten islands
The Takuu group of atolls is home to a rich and historic culture, but the resilient people and their idyllic islands face an increasingly dire threat from climate change.

The Australian plan?
There is no Australian Government adaptation plan to address the health impacts of climate change.
Instead, there are different responses by state and territories public health authorities, which are mostly inadequate.
Non-Government organisations such as the Climate and Health Alliance have detailed what federal and other governments must consider when they decide to act.
There is no national leadership on this issue. Leaders must be able to explain vital policy and carry people with them. This means explaining to Australians the threats to their life-support systems —stable climate, water, biodiversity and productive land.
Were any of these words mentioned by our leaders in the five recent by-elections?
Climate change threatens our existence — the best thing politicians can do now is to listen to those with science, technology and health expertise. 

'Science can't provide moral energy'
Hear on Science Friction why Mike Hulme thinks only the human imagination will help us now when it comes to the climate.

Why we need new laws
A "new generation" of environmental laws is needed to protect the Australian public. The Australian Panel of Experts on Environmental Law has drafted eight sets of recommendations to reform Australia's environmental laws.
These reforms would establish two independent bodies:
  • A National Sustainability Commission to set national environmental standards, undertake strategic regional planning and report on national environmental performance
  • A National Environmental Protection Authority to conduct transparent environmental assessments and inquiries, plus monitoring, compliance and enforcement activities
The new laws would replace the Environment Protection and Biodiversity Conservation Act which is inadequate to protect biodiversity and ecological communities.
These reformed laws would inform effective policy on climate adaptation that protects human health. They could also support many other complex problems subject to political paralysis, such as the Murray Darling Basin water-plan and the national regulation of tree clearing.
New environmental laws and a climate change adaptation plan are vital to this nation's security, health, economy and environment, and so to our future.

Scorched Earth: Counting The Costs Of Extreme Weather

AFR - Leslie Hook | Kerin Hope

Girogos Handrinos stands outside his burned house in Mati, east of Athens. The impact of Greece's fires was worsened because its emergency services have faced severe budget cuts during the country's financial crisis. Thanassis Stavrakis
London/Athens: Thanasis Kontidis was hosing down the veranda of his family's summer home in Mati last Monday afternoon when he caught a whiff of acrid smoke. "I looked up and saw the sky was a beige colour so I knew there was a fire somewhere. But I didn't realise it was getting close."
Half an hour later the 22-year-old university student was fleeing for his life.
"The wind was gusting in different directions and there was an orange glow in the distance," he says. "I soaked one of my mother's scarves, tied it over my nose and mouth and grabbed my phone. Then I got in the car and tried to get away."
But the narrow streets of the Greek seaside resort surrounded by pine forests were already jammed with vehicles rushing to escape the fire. Mr Kontidis abandoned his car and started running towards the sea.
While fires are common in some parts of the world such as California and Australia, what is unusual about this year is that these disasters are happening in different places, catching people unawares.
While he survived, 87 people were killed in the blazes in and around Athens, with 100 still missing. The blaze was unprecedented for Greece, officials say. But it is one of several freak fire and extreme heat events from Canada to Portugal and Japan over the past year that have raised alarm about the impact of changing weather patterns on people's lives.
Climate change is an "accelerant" for these fires, according to the scientists who study them, although it is not the only reason. Urbanisation, changing land use patterns, the arrival of invasive species and even austerity are contributory factors. There have been more than 450 fires covering land of more than 30 hectares in Europe so far this year, according to EU data, which is 40 per cent higher than the average over the past decade.
While fires are common in some parts of the world such as California and Australia, what is unusual about this year is that these disasters are happening in different places, catching people unawares. Fires burning inside the Arctic Circle are the result of drought and heat that have made forests there unusually combustible. Peat lands in the UK, traditionally protected from blazes by moisture, have also been burning amid a heatwave. In the US, the annual average number of large fires has doubled since the 1970s, and this week Yosemite Valley, a national park in California, was evacuated due to a nearby fire.
"There are a lot of extreme fire events occurring," says David Bowman, a professor of fire ecology at the University of Tasmania. He points to the Thomas fire that ravaged Los Angeles' suburbs and freak fires in central Chile last year. "It's not normal — I shouldn't be overwhelmed with opportunities to study extreme fire events."
There is also a growing understanding of their cost. The recent fires have highlighted some of these, both economic and human: 87 people dead in Athens, $US100m worth of forests burnt in Sweden and more than $US2b spent on fire fighting in the US last year. "With each extreme weather event, we get new information for our actuarial models for how likely these events are and their cost," says Trevor Houser, co-director of Climate Impact Lab.

In Sweden, authorities have struggled to respond because their firefighting force is not sufficient to handle blazes of such size — the burnt area is 40 times greater than the annual average in the country over the past decade, and the fires are still burning out of control. Other European countries have sent in assistance.
In Greece, which had not suffered a prolonged heatwave before the blaze, the dense illegal housing, high winds and slow response from authorities were key reasons why the fires became so devastating, says Efthymios Lekkas, an Athens university tectonics and geology professor. The impact was worsened because its emergency services have faced severe budget cuts during the country's financial crisis. Local government officials in Mati also failed this year to complete an annual clearing of undergrowth required by law, leaving a thick layer of combustible pine needles and dead branches on pavements and in public spaces around the resort.
"You need a number of ingredients, for wildfires in particular. Climate change is only one factor, but it is a very important factor," says Rowan Sutton, director of climate research for the UK National Centre for Atmospheric Research. "If it is hotter and drier, the risk is greater."
Climate change is central to scientists' understanding of which areas are likely to face greater fire risks in the future. Areas such as the forests in the UK are expected to see an increase in fires as conditions become hotter.
There have been more than 450 fires covering land of more than 30 hectares in Europe so far this year, according to EU data, which is 40 per cent higher than the average over the past decade.
This summer's fires come at a time of growing concern about extreme weather events that have lashed the planet, from hurricanes, to heatwaves, to floods. While specific weather events cannot be directly attributed to the rising levels of carbon in the atmosphere, there is a correlation between climate change and the increasing frequency of these natural disasters.
However, calculating the economic impact of climate change remains a field that is part art, part science, because of the great uncertainties about how much, and how rapidly, global temperatures and weather patterns will change.
Lloyds, the London-based insurance market, estimates that as much as $123bn in global gross domestic product in cities could be at risk from the impact of a warming planet, including windstorms and floods.
Meanwhile, a 2015 study by the journal Nature found that due to climate change, global incomes were likely to be one-fifth lower in 2100 than they would be with a stable climate. And later this year the UN will issue a landmark report that quantifies the impact of 1.5C of warming, compared with 2C. Leaked copies suggest that the world will pass the 1.5-degree warming target by about 2040.

The Paris climate agreement signed in 2016 commits more than 170 countries to limit global warming to well below 2C. However, many of the signatories have not made commensurate commitments to reach that goal. A growing number of scientists believe warming is likely to exceed 2C.
The biggest concern, according to Sam Fankhauser, director of the UK's Grantham Research Institute, is what happens if the planet exceeds that 2C warming target on which many economic analyses are based.
"If you just say it costs 3 per cent, 4 per cent or 5 per cent of GDP . . . that misses the whole story of, what happens if it goes really, really bad." Mass relocations of populations, water shortages and increased conflict caused by displacement are among the worst-case scenarios.
"People are starting to have the feeling that it might be a lot worse than some of the estimates suggest," says Mr Fankhauser, referring to the economic modelling. "Now that you experience it, [it] feels a bit more unpleasant than what the models would have said".

On average, richer countries in the northern hemisphere will see less negative impacts than poorer countries closer to the equator, according to the study in Nature. Some countries could even benefit. For example in Sweden, global warming could mean more sunshine and faster-growing forests, providing a boost to its timber industry.
Stephane Hallegatte, a senior economist in the World Bank's climate change group, says one of the things that will determine the cost of climate change is how quickly people adapt and prepare for a warmer world.
"If you assume that nobody acts until there is a disaster, then with the same change in physical conditions you can have a very high cost," he says.
"The key thing is to see this fire in Sweden not as a Swedish event. People in different parts of the world, say Canada or Russia, should look at this and think this is exactly what they have to expect."
Like other aspects of climate change, adapting to fire risk is difficult: the cost can be hard for societies to accept, when there is a perception that the risks are uncertain. Prof Bowman, the fire scientist, says building codes and urban design need to take fire risks into account. Better land management and landscape features such as fire breaks, parks and golf courses can help reduce fire risk in some areas.
"We haven't got time to debate things, we really need to move into the adaptive mode. But there are . . . always reasons to kick the can down the road," he says, adding that countries are moving far too slowly to address growing fire risks.
"So our adaptive process will be a zigzag reacting to fire disasters. It is heartbreaking, but unfortunately that seems to be the trajectory we are on, we will just have to deal with more death and destruction."
