Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Record floods across the globe
IVORY COAST: Floods and landslides killed at least 24 people in Ivory Coast’s largest city of Abidjan after a week of heavy rains that was “four times the usual volume in some cases”, the Associated Press reported. The newswire added that the city’s disadvantaged communities are “particularly vulnerable” because of poor storm drainage in informal settlements.
CHINA ‘SWAMPED’: Landslides killed eight people in their homes in southern China’s Hunan province, said the South China Morning Post, with Taoyuan county receiving 39.5cm of rain in a day. Record rains “swamped” Hunan’s capital of Changsha, “turning roads into rivers and submerging subway tunnels”, Reuters wrote. By Monday, 33 rivers had “exceeded warning levels”, Xinhua reported. Associated Press also reported that flooding killed two people in the “deluged” US midwest.
BANGLADESH INUNDATED: Widespread flooding has stranded nearly two million people in north-east Bangladesh, CNN reported. It added that “large swathes” of Sylhet and Sunamganj provinces were underwater after a second wave of flooding hit the region in less than a month, with 772,000 children “in urgent need of assistance”. Camps in Cox’s Bazaar that accommodate “almost [one million] documented [Rohingya] refugees have been overrun by the incoming floodwaters”, Down to Earth reported, with at least 10 Rohingya fatalities out of the total 31 deaths in the Bangladesh floods this year.
Heat deaths: tolls apart
PAKISTAN’S FATAL HEAT: Doctors in Karachi “treated thousands of victims of heatstroke at various hospitals” after a “days-long heatwave” scorched southern Pakistan, the Associated Press reported. While local media reported that the heatwave “killed more than two dozen people” in Karachi alone, AP added that “no government spokesman was available to confirm the number of heatstroke-related deaths”. However, the Edhi ambulance service told BBC News it had taken around 568 people’s bodies to the Karachi city morgue in Pakistan over the past six days – up from its usual rate of 30-40 bodies a day.
‘TOLLS APART’: In neighbouring India, the country’s health ministry said 143 people across the country had died of heatstroke from the start of summer until 20 June, far lower than 209 confirmed and 448 suspected deaths tallied by Times of India. Meanwhile, a non-profit report estimated that “192 homeless individuals died from the heat in just nine days” in the national capital region alone, experts in India Development Review Online wrote, “highlighting the significant underreporting of heat-related deaths” in the country.
CULPABLE HEAT: In the US, the Boston Globe reported that New England experienced the “highest rate of heat-related emergency department visits” in the country, with temperatures in the region crossing 32C. Meanwhile, prosecutors in Arizona could “reasonably press homicide charges against big oil” for heat deaths in the state last year, the Guardian reported. Finally, Reuters wrote that the “sweltering summer” is worsening conditions in Gaza, where “nearly all the 2.3 million inhabitants have been driven from their homes by Israel’s military campaign” with almost no access to electricity and little clean water.
Around the world
- COW TAX: Denmark is set to introduce the world’s first carbon tax on agriculture after a historic agreement on Monday, Politico reported. Farmers will be charged “almost €100 a year” per cow once the levy rolls out in 2030, Financial Times said.
- PARLEY VOUS: In a “new and surprising” move, South China Morning Post reported that China agreed to talks with the EU over its plans to raise tariffs on electric vehicle imports by 48%.
- MAI KUHIHEWA: Youth in the US state of Hawaii who sued transport authorities for their use of fossil fuels reached a “first-of-its-kind” settlement that recognised their “constitutional rights to a life-sustaining climate”, Teen Vogue reported.
- OILSTRUCK: Financial Times reported on ExxonMobil’s development of “one of the largest offshore oil developments in history” and what it could mean for Guyana.
- BP U-TURN: Oil and gas giant BP has imposed a hiring freeze and paused new offshore wind projects to place a greater emphasis on oil and gas rather than renewables amid investor discontent, sources at the company told Reuters.
- PIPELINE PROTESTS: 37 activists in Uganda were arrested for protesting the East African Crude Oil Pipeline (EACOP), calling on China to “reject financial support” to the project, All Africa reported.
£116bn £30bn £2.8tn
Some of the “scary-sounding” numbers being used to mislead the public about the “cost” of net-zero in the UK general-election campaign. Carbon Brief’s Dr Simon Evans has factchecked them.
Latest climate research
- A new study in Nature Ecology and Evolution found that Earth’s most extreme wildfires increased 2.2-fold in the past 20 years, with the last seven years seeing the six most extreme fires on record.
- According to new research in Nature Climate Change, a 1C rise in average temperatures would mean four extra minutes every day spent collecting water for women. By 2050, women could spend 30% and 100% more time – globally and regionally – collecting water, “undermining” their welfare.
- New research on grounding zones – where ice transitions from land to water – suggests that sea-level rise projections could be substantially underestimated, according to a Carbon Brief guest post.

Captured

New Carbon Brief analysis found that UK governments in England, Scotland, Wales and Northern Ireland have missed their tree-planting targets set in 2020 and failed to plant an area of forest nearly the size of Birmingham. Tree-planting is a “significant” part of the UK’s net-zero strategy to compensate for other polluting sectors. By 2050, the unplanted trees would have removed some 8.5m tonnes of CO2 from the atmosphere, roughly 2% of the UK’s annual emissions in 2023. This shortfall will need to be made up for with stronger efforts elsewhere if the UK’s net-zero by 2050 target is to be met.
Spotlight
Monsoon mixtape
As the UK gears up for Glastonbury, Carbon Brief interviews pioneering Indian hip-hop and folk artists about protest music and the role of artists in an era of climate change.
When Carbon Brief spoke to the Marathi-language rapper MC Mawali from the hip-hop collective Swadesi, Mumbai was under an orange alert for extremely heavy rains, after stalling for most of the month.
The monsoon has changed along with the mega-city most defined by it. Massive infrastructure projects have cost the island city its flood buffers, including the much-diminished Aarey forest, home to the Indigenous Warli tribe and the only urban leopard population in the world.
In 2019, Mawali, along with fellow Swadesi rappers and Warli bard Prakash Bhoir, gave Mumbai’s #SaveAarey movement its protest anthem, The Warli Revolt – its chorus warning of a dystopian climate future to come.
“I used to go to Aarey to swim in the Vihar lake as a kid, but I didn’t know about [Warli] culture, their instruments, their songs going extinct that are not on the internet,” said Mawali.
When the chainsaws came for the forest, Mawali says he “felt helpless”, but he’s happy to hear that Warli Revolt has become a go-to anti-deforestation anthem across the country since. He added:
“Today’s music business is about labels pouring in music and splashing their artists all over platforms that censor messages like ours, but, through hip-hop, we’ve learned to hijack that same system to keep folk, tribal and conscious music alive.”
To anti-caste singer-poet Dhammarakshit Randive from the Yalgaar Sanskrutik Manch collective, the word “green” has turned into “its own kind of propaganda” that justifies “ask-no-questions development”, with high displacement of people and a large emissions footprint.
“‘Green’ often becomes propaganda, telling us you can offset 100 trees in a biodiverse forest that Adivasis (Indigenous peoples) depend on by planting another 1,000 somewhere else,” he told Carbon Brief.
Randive sees climate change, anti-caste and “movements to centre democracy” as interlinked, “affecting all our lives, everywhere”. To him, the main role of musicians and artists in responding to climate change is to establish that intersectionality. He told Carbon Brief:
“Otherwise, those fighting for forests are dying unheard in those same forests, sanitation workers are dying in the same sewers, factory workers are dying in the heat and there’s no one to widen peoples’ perspectives to say ‘this is all part of the same struggle’.”
Taru Dalmia, also known as Delhi Sultanate, was among the earliest pioneers to fuse dub and dancehall with protest anthems penned by Indigenous singers, such as Bhagaban Majhi, protesting mining projects in central India. Blood Earth, the album Dalmia made with producer Chris McGuiness, is now 12-years-old, but remains just as relevant.
“At that time we made it, I felt that there was a kind of hidden violence and not as much discourse about a war-like situation in [mineral-rich Indian states],” said Dalmia, speaking to Carbon Brief. He feels that, since then, “there’s definitely more awareness and politicisation which has to do with how much more repressive things have gotten and [environmental and other] issues staring at us in the face”.
While hip-hop has “blown up” over the past half-decade, he feels that little has changed as far as mining companies are concerned, since “profit margins remain huge”. Dalmia added:
“This awareness of how fundamentally our way of life is based on extraction, extractive industries and destruction and how that’s a direct continuation of the colonial project…sure, there’s more politicisation, but the depth of it is still missing.”
While extreme weather has not quite made its way to the airwaves, aside from boilerplate Bollywood songs invoking heat and rain, mercury levels were the subject of one of India’s earliest environmental campaign songs.

In 2015, a young Sofia Ashraf dropped the single Kodaikanal Won’t, a rap parody of Nicki Minaj’s Anaconda, demanding that Unilever clean up toxic waste from its thermometer factory dumped in the rainforest and compensate its workers for mercury poisoning. It drew over 2m views, praise from Minaj and a public apology and settlement from Unilever. Speaking to Carbon Brief, Ashraf said:
“Since Kodaikanal Won’t, there has been a whole gamut of songs around climate change, from general awareness-building to pointed information-sharing, music has been used effectively to express the dread a lot of us live under. The downside is that greenwashing is constantly on the rise and there is too much onus on the audience to parse this content for the truth.”
But she remains optimistic, telling Carbon Brief:
“As long as art still strives to build conscious narratives, I feel we are headed in the right direction.”
Watch, read, listen
PETROCENTRIC: Adam Hanieh, author and professor of political economy at the University of Exeter, spoke to the Break Down about all the ways in which oil came to “permeate” our lives.
MIC TEST: Vox tuned in to how scientists are listening to Puerto Rico’s frogs to understand how climate change is altering life on the rainforest island.
NON-ALIGNED: A piece in Drilled unpacked new research prompting questions of what “Paris-aligned” means and whether “climate pledges…need a terminology overhaul”.

The 2026 budget test: Will Australia break free from fossil fuels?
In 2026, the dangers of fossil fuel dependence have been laid bare like never before. The illegal invasion of Iran has brought pain and destruction to millions across the Middle East and triggered a global energy crisis impacting us all. Communities in the Pacific have been hit especially hard by rising fuel prices, and Australians have seen their cost-of-living woes deepen.
Such moments of crisis and upheaval can lead to positive transformation. But only when leaders act with courage and foresight.
There is no clearer statement of a government’s plans and priorities for the nation than its budget — how it plans to raise money, and what services, communities, and industries it will invest in.
As we count down the days to the 2026-27 Federal Budget, will the Albanese Government deliver a budget for our times? One that starts breaking the shackles of fossil fuels, accelerates the shift to clean energy, protects nature, and sees us work together with other countries towards a safer future for all? Or one that doubles down on coal and gas, locks in more climate chaos, and keeps us beholden to the whims of tyrants and billionaires.
Here’s what we think the moment demands, and what we’ll be looking out for when Treasurer Jim Chalmers steps up to the dispatch box on 12 May.
1. Stop fuelling the fire
2. Make big polluters pay
3. Support everyone to be part of the solution
4. Build the industries of the future
5. Build community resilience
6. Be a better neighbour
7. Protect nature
1. Stop fuelling the fire

In mid-April, Pacific governments and civil society met to redouble their efforts towards a Fossil Fuel Free Pacific. Moving beyond coal, oil and gas is fundamental to limiting warming to 1.5°C — a survival line for vulnerable communities and ecosystems. And as our Head of Pacific, Shiva Gounden, explained, it is “also a path of liberation that frees us from expensive, extractive and polluting fossil fuel imports and uplifts our communities”.
Pacific countries are at the forefront of growing global momentum towards a just transition away from fossil fuels, and it is way past time for Australia to get with the program. It is no longer a question of whether fossil fuel extraction will end, but whether that end will be appropriately managed and see communities supported through the transition, or whether it will be chaotic and disruptive.
So will this budget support the transition away from fossil fuels, or will it continue to prop up coal and gas?
When it comes to sensible moves the government can make right now, one stands out as a genuine low hanging fruit. Mining companies get a full rebate of the excise (or tax) that the rest of us pay on diesel fuel. This lowers their operating costs and acts as a large, ongoing subsidy on fossil fuel production — to the tune of $11 billion a year!
Greenpeace has long called for coal and gas companies to be removed from this outdated scheme, and for the billions in savings to be used to support the clean energy transition and to assist communities with adapting to the impacts of climate change. Will we see the government finally make this long overdue change, or will it once again cave to the fossil fuel lobby?
2. Make big polluters pay

While our communities continue to suffer the escalating costs of climate-fuelled disasters, our Government continues to support a massive expansion of Australia’s export gas industry. Gas is a dangerous fossil fuel, with every tonne of Australian gas adding to the global heating that endangers us all.
Moreover, companies like Santos and Woodside pay very little tax for the privilege of digging up and selling Australians’ natural endowment of fossil gas. Remarkably, the Government currently raises more tax from beer than from the Petroleum Resource Rent Tax (PRRT) — the main tax on gas profits.
Momentum has been building to replace or supplement the PRRT with a 25% tax on gas exports. This could raise up to $17 billion a year — funds that, like savings from removing the diesel tax rebate for coal and gas companies, could be spent on supporting the clean energy transition and assisting communities with adapting to worsening fires, floods, heatwaves and other impacts of climate change.
As politicians arrive in Canberra for budget week, they will be confronted by billboards calling for a fair tax on gas exports. The push now has the support of dozens of organisations and a growing number of politicians. Let’s hope the Treasurer seizes this rare window for reform.
3. Support everyone to be part of the solution
As the price of petrol and diesel rises, electric vehicles (EVs) are helping people cut fuel use and save money. However, while EV sales have jumped since the invasion of Iran sent fuel prices rising, they still only make up a fraction of total new car sales. This budget should help more Australians switch to electric vehicles and, even more importantly, enable more Australians to get around by bike, on foot, and on public transport. This means maintaining the EV discount, investing in public and active transport, and removing tax breaks for fuel-hungry utes and vans.
Millions of Australians already enjoy the cost-saving benefits of rooftop solar, batteries, and getting off gas. This budget should enable more households, and in particular those on lower incomes, to access these benefits. This means maintaining the Cheaper Home Batteries Program, and building on the Household Energy Upgrades Fund.
4. Build the industries of the future

If we’re to transition away from fossil fuels, we need to be building the clean industries of the future.
No state is more pivotal to Australia’s energy and industrial transformation than Western Australia. The state has unrivaled potential for renewable energy development and for replacing fossil fuel exports with clean exports like green iron. Such industries offer Western Australia the promise of a vibrant economic future, and for Australia to play an outsized positive role in the world’s efforts to reduce emissions.
However, realising this potential will require focussed support from the Federal Government. Among other measures, Greenpeace has recommended establishing the Australasian Green Iron Corporation as a joint venture between the Australian and Western Australian governments, a key trading partner, a major iron ore miner and steel makers. This would unite these central players around the complex task of building a large-scale green iron industry, and unleash Western Australia’s potential as a green industrial powerhouse.
5. Build community resilience
Believe it or not, our Government continues to spend far more on subsidising fossil fuel production — and on clearing up after climate-fuelled disasters — than it does on helping communities and industries reduce disaster costs through practical, proven methods for building their resilience.
Last year, the Government estimated that the cost of recovery from disasters like the devastating 2022 east coast floods on 2019-20 fires will rise to $13.5 billion. For contrast, the Government’s Disaster Ready Fund – the main national source of funding for disaster resilience – invests just $200 million a year in grants to support disaster preparedness and resilience building. This is despite the Government’s own National Emergency Management Agency (NEMA) estimating that for every dollar spent on disaster risk reduction, there is a $9.60 return on investment.
By redirecting funds currently spent on subsidising fossil fuel production, the Government can both stop incentivising climate destruction in the first place, and ensure that Australian communities and industries are better protected from worsening climate extremes.
No communities have more to lose from climate damage, or carry more knowledge of practical solutions, than Aboriginal and Torres Strait Islander peoples. The budget should include a dedicated First Nations climate adaptation fund, ensuring First Nations communities can develop solutions on their own terms, and access the support they need with adapting to extreme heat, coastal erosion and other escalating challenges.
6. Be a better neighbour
The global response to climate change depends on the adequate flow of support from developed economies like Australia to lower income nations with shifting to clean energy, adapting to the impacts of climate change, and addressing loss and damage.
Such support is vital to building trust and cooperation, reducing global emissions, and supporting regional and global security by enabling countries to transition away from fossil fuels and build greater resilience.
Despite its central leadership role in this year’s global climate negotiations, our Government is yet to announce its contribution to international climate finance for 2025-2030. Greenpeace recommends a commitment of $11 billion for this five year period, which is aligned with the global goal under the Paris Agreement to triple international climate finance from current levels.
This new commitment should include additional funding to address loss and damage from climate change and a substantial contribution to the Pacific Resilience Facility, ensuring support is accessible to countries and communities that need it most. It should also see Australia get firmly behind the vision of a Fossil Fuel Free Pacific.
7. Protect nature

There is no safe planet without protection of the ecosystems and biodiversity that sustain us and regulate our climate.
Last year the Parliament passed important and long overdue reforms to our national environment laws to ensure better protection for our forests and other critical ecosystems. However, the Government will need to provide sufficient funding to ensure the effective implementation of these reforms.
Greenpeace has recommended $500 million over four years to establish the National Environment Agency — the body responsible for enforcing and monitoring the new laws — and a further $50 million to Environment Information Australia for providing critical information and tools.
Further resourcing will also be required to fulfil the crucial goal of fully protecting 30% of Australian land and seas by 2030. This should include $1 billion towards ending deforestation by enabling farmers and loggers to retool away from destructive practices, $2 billion a year for restoring degraded lands, $5 billion for purchasing and creating new protected areas, and $200 million for expanding domestic and international marine protected areas.
Conclusion
This is not the first time that conflict overseas has triggered an energy crisis, or that a budget has been preceded by a summer of extreme weather disasters, highlighting the urgent need to phase out fossil fuels. What’s different in 2026 is the availability of solutions. Renewable energy is now cheaper and more accessible than ever before. Global momentum is firmly behind the transition away from fossil fuels. The Albanese Government, with its overwhelming majority, has the chance to set our nation up for the future, or keep us stranded in the past. Let’s hope it makes some smart choices.
The 2026 budget test: Will Australia break free from fossil fuels?

What fossil fuels really cost us in a world at war
Anne Jellema is Executive Director of 350.org.
The war on Iran and Lebanon is a deeply unjust and devastating conflict, killing civilians at home, destroying lives, and at the same time sending shockwaves through the global economy. We, at 350.org, have calculated, drawing on price forecasts from the International Monetary Fund (IMF) and Goldman Sachs, just how much that volatility is costing us.
Even under the IMF’s baseline scenario – a de facto “best case” scenario with a near-term end to the war and related supply chain disruptions – oil and gas price spikes are projected to cost households and businesses globally more than $600 billion by the end of the year. Under the IMF’s “adverse scenario”, with prolonged conflict and sustained price pressures, we estimate those additional costs could exceed $1 trillion, even after accounting for reduced demand.
Which is why we urgently need a power shift. Governments are under growing pressure to respond to rising fuel and food costs and deepening energy poverty. And it’s becoming clearer to both voters and elected officials that fossil dependence is not only expensive and risky, but unnecessary.
People who can are voting with their wallets: sales of solar panels and electric vehicles are increasing sharply in many countries. But the working people who have nothing to spare, ironically, are the ones stuck with using oil and gas that is either exorbitantly expensive or simply impossible to get.
Drain on households and economies
In India, street food vendors can’t get cooking gas and in the Philippines, fishermen can’t afford to take their boats to sea. A quarter of British people say that rising energy tariffs will leave them completely unable to pay their bills. This is the moment for a global push to bring abundant and affordable clean energy to all.
In April, we released Out of Pocket, our new research report on how fossil fuels are draining households and economies. We were surprised by the scale of what we found. For decades, governments have reassured people that energy price spikes are unfortunate but unavoidable – the result of distant conflicts, market forces or geopolitical shocks beyond anyone’s control. But the numbers tell a different story.
What we are living through today is not an energy crisis. It is a fossil fuel crisis. In just the first 50 days of the Middle East conflict, soaring oil and gas prices have siphoned an estimated $158 billion–$166 billion from households and businesses worldwide. That is money extracted directly from people’s pockets and transferred, almost instantly, into fossil fuel company balance sheets. And this figure only captures the immediate impact of price spikes, not the permanent economic drain of fossil dependence. Fossil fuels don’t just cost us once, they cost us over and over again.
First, through our bills. Every time there is a war, an embargo or a supply disruption, fossil fuel prices surge. For ordinary people, this means higher costs for energy, transport and food. Many Global South countries have little or no fiscal space to buffer the shock; instead, workers and families pay the price.
Second, through our taxes. Governments around the world continue to pour vast sums of public money into fossil fuel subsidies. These are often justified as a way to protect the most vulnerable at the petrol pump or in their homes. But in reality, the benefits are overwhelmingly captured by wealthier households and corporations. The poorest 20% receive just a fraction of this support, while public finances are drained.
Third, through climate impacts. New research across more than 24,000 global locations gives a granular account of the true costs of extreme heat, sea level rise and falling agricultural yields. Using this data to update IMF modelling of the social cost of carbon, we found that fossil fuel impacts on health and livelihoods amount to over $9 trillion a year. This is the biggest subsidy of all, because these massive and mounting costs are not charged to Big Oil – they are paid for by governments and households, with the poorest shouldering the lion’s share.
Massive transfer of wealth to fossil fuel industry
Adding up direct subsidies, tax breaks and the unpaid bill for climate damages, the total transfer of wealth from the public to the fossil fuel industry amounts to $12 trillion even in a “normal” year without a global oil shock. That’s more than 50% higher than the IMF has previously estimated, and equivalent to a staggering $23 million a minute.
The fossil fuel industry has become extraordinarily adept at profiting from instability. When conflict drives up prices, companies do not lose, they gain. In the current crisis, oil producers and commodity traders are on track to secure tens of billions of dollars in additional windfall profits, even as households face rising bills and governments struggle to manage the fallout.
Fossil fuel crisis offers chance to speed up energy transition, ministers say
This growing disconnect is impossible to ignore. Investors are advised to buy into fossil fuel firms precisely because of their ability to generate profits in times of crisis. Meanwhile, ordinary people are told to tighten their belts.
In 2026, unlike during the oil shocks of the 1970s, clean energy is no longer a distant alternative. Now, even more than when gas prices spiked due to Russia’s invasion of Ukraine in 2022, renewables are often the cheapest option available. Solar and wind can be deployed quickly, at scale, and without the volatility that defines fossil fuel markets.
How to transition from dirty to clean energy
The solutions are clear. Governments must implement permanent windfall taxes on fossil fuel companies to ensure that extraordinary profits generated during crises are redirected to support households. These revenues can be used to reduce energy bills, invest in public services, and accelerate the rollout of clean energy.
Second, we must shift subsidies away from fossil fuels and towards renewable solutions, particularly those that can be deployed quickly and equitably, such as rooftop and community solar. This is not just about cutting emissions. It is about building a more stable, fair and resilient energy system.
Finally, we need binding plans to phase out fossil fuels altogether, replacing them with homegrown renewable energy that can shield economies from future shocks. Because what the current crisis has made clear is this: as long as we remain dependent on fossil fuels, we remain vulnerable – to conflict, to price volatility and to the escalating impacts of climate change.
The true price of fossil fuels is no longer hidden. It is visible in rising bills, strained public finances and communities pushed to the brink. And it is being paid, every day, by ordinary people around the world.
It’s time for the great power shift.
Full details on the methodology used for this report are available here.

Traditional models still ‘outperform AI’ for extreme weather forecasts
Computer models that use artificial intelligence (AI) cannot forecast record-breaking weather as well as traditional climate models, according to a new study.
It is well established that AI climate models have surpassed traditional, physics-based climate models for some aspects of weather forecasting.
However, new research published in Science Advances finds that AI models still “underperform” in forecasting record-breaking extreme weather events.
The authors tested how well both AI and traditional weather models could simulate thousands of record-breaking hot, cold and windy events that were recorded in 2018 and 2020.
They find that AI models underestimate both the frequency and intensity of record-breaking events.
A study author tells Carbon Brief that the analysis is a “warning shot” against replacing traditional models with AI models for weather forecasting “too quickly”.
AI weather forecasts
Extreme weather events, such as floods, heatwaves and storms, drive hundreds of billions of dollars in damages every year through the destruction of cropland, impacts on infrastructure and the loss of human life.
Many governments have developed early warning systems to prepare the general public and mobilise disaster response teams for imminent extreme weather events. These systems have been shown to minimise damages and save lives.
For decades, scientists have used numerical weather prediction models to simulate the weather days, or weeks, in advance.
These models rely on a series of complex equations that reproduce processes in the atmosphere and ocean. The equations are rooted in fundamental laws of physics, based on decades of research by climate scientists. As a result, these models are referred to as “physics-based” models.
However, AI-based climate models are gaining popularity as an alternative for weather forecasting.
Instead of using physics, these models use a statistical approach. Scientists present AI models with a large batch of historical weather data, known as training data, which teaches the model to recognise patterns and make predictions.
To produce a new forecast, the AI model draws on this bank of knowledge and follows the patterns that it knows.
There are many advantages to AI weather forecasts. For example, they use less computing power than physics-based models, because they do not have to run thousands of mathematical equations.
Furthermore, many AI models have been found to perform better than traditional physics-based models at weather forecasts.
However, these models also have drawbacks.
Study author Prof Sebastian Engelke, a professor at the research institute for statistics and information science at the University of Geneva, tells Carbon Brief that AI models “depend strongly on the training data” and are “relatively constrained to the range of this dataset”.
In other words, AI models struggle to simulate brand new weather patterns, instead tending forecast events of a similar strength to those seen before. As a result, it is unclear whether AI models can simulate unprecedented, record-breaking extreme events that, by definition, have never been seen before.
Record-breaking extremes
Extreme weather events are becoming more intense and frequent as the climate warms. Record-shattering extremes – those that break existing records by large margins – are also becoming more regular.
For example, during a 2021 heatwave in north-western US and Canada, local temperature records were broken by up to 5C. According to one study, the heatwave would have been “impossible” without human-caused climate change.
The new study explores how accurately AI and physics-based models can forecast such record-breaking extremes.
First, the authors identified every heat, cold and wind event in 2018 and 2020 that broke a record previously set between 1979 and 2017. (They chose these years due to data availability.) The authors use ERA5 reanalysis data to identify these records.
This produced a large sample size of record-breaking events. For the year 2020, the authors identified around 160,000 heat, 33,000 cold and 53,000 wind records, spread across different seasons and world regions.
For their traditional, physics-based model, the authors selected the High RESolution forecast model from the Integrated Forecasting System of the European Centre for Medium-Range Weather Forecasts. This is “widely considered as the leading physics-based numerical weather prediction model”, according to the paper.
They also selected three “leading” AI weather models – the GraphCast model from Google Deepmind, Pangu-Weather developed by Huawei Cloud and the Fuxi model, developed by a team from Shanghai.
The authors then assessed how accurately each model could forecast the extremes observed in the year 2020.
Dr Zhongwei Zhang is the lead author on the study and a researcher at Karlsruhe Institute of Technology. He tells Carbon Brief that many AI weather forecast models were built for “general weather conditions”, as they use all historical weather data to train the models. Meanwhile, forecasting extremes is considered a “secondary task” by the models.
The authors explored a range of different “lead times” – in other words, how far into the future the model is forecasting. For example, a lead time of two days could mean the model uses the weather conditions at midnight on 1 January to simulate weather conditions at midnight on 3 January.
The plot below shows how accurately the models forecasted all extreme events (left) and heat extremes (right) under different lead times. This is measured using “root mean square error” – a metric of how accurate a model is, where a lower value indicates lower error and higher accuracy.
The chart on the left shows how two of the AI models (blue and green) performed better than the physics-based model (black) when forecasting all weather across the year 2020.
However, the chart on the right illustrates how the physics-based model (black) performed better than all three AI models (blue, red and green) when it came to forecasting heat extremes.

The authors note that the performance gap between AI and physics-based models is widest for lower lead times, indicating that AI models have greater difficulty making predictions in the near future.
They find similar results for cold and wind records.
In addition, the authors find that AI models generally “underpredict” temperature during heat records and “overpredict” during cold records.
The study finds that the larger the margin that the record is broken by, the less well the AI model predicts the intensity of the event.
‘Warning shot’
Study author Prof Erich Fischer is a climate scientist at ETH Zurich and a Carbon Brief contributing editor. He tells Carbon Brief that the result is “not unexpected”.
He adds that the analysis is a “warning shot” against replacing traditional models with AI models for weather forecasting “too quickly”.
The analysis, he continues, is a “warning shot” against replacing traditional models with AI models for weather forecasting “too quickly”.
AI models are likely to continue to improve, but scientists should “not yet” fully replace traditional forecasting models with AI ones, according to Fischer.
He explains that accurate forecasts are “most needed” in the runup to potential record-breaking extremes, because they are the trigger for early warning systems that help minimise damages caused by extreme weather.
Leonardo Olivetti is a PhD student at Uppsala University, who has published work on AI weather forecasting and was not involved in the study.
He tells Carbon Brief that “many other studies” have identified issues with using AI models for “extremes”, but this paper is novel for its specific focus on extremes.
Olivetti notes that AI models are already used alongside physics-based models at “some of the major weather forecasting centres around the world”. However, the study results suggest “caution against relying too heavily on these [AI] models”, he says.
Prof Martin Schultz, a professor in computational earth system science at the University of Cologne who was not involved in the study, tells Carbon Brief that the results of the analysis are “very interesting, but not too surprising”.
He adds that the study “justifies the continued use of classical numerical weather models in operational forecasts, in spite of their tremendous computational costs”.
Advances in forecasting
The field of AI weather forecasting is evolving rapidly.
Olivetti notes that the three AI models tested in the study are an “older generation” of AI models. In the last two years, newer “probabilistic” forecast models have emerged that “claim to better capture extremes”, he explains.
The three AI models used in the analysis are “deterministic”, meaning that they only simulate one possible future outcome.
In contrast, study author Engelke tells Carbon Brief that probabilistic models “create several possible future states of the weather” and are therefore more likely to capture record-breaking extremes.
Engelke says it is “important” to evaluate the newer generation of models for their ability to forecast weather extremes.
He adds that this paper has set out a “protocol” for testing the ability of AI models to predict unprecedented extreme events, which he hopes other researchers will go on to use.
The study says that another “promising direction” for future research is to develop models that combine aspects of traditional, physics-based weather forecasts with AI models.
Engelke says this approach would be “best of both worlds”, as it would combine the ability of physics-based models to simulate record-breaking weather with the computational efficiency of AI models.
Dr Kyle Hilburn, a research scientist at Colorado State University, notes that the study does not address extreme rainfall, which he says “presents challenges for both modelling and observing”. This, he says, is an “important” area for future research.
