Welcome to Carbon Brief’s Cropped.
We handpick and explain the most important stories at the intersection of climate, land, food and nature over the past fortnight.
Key developments
Protecting the Amazon
ILLEGAL FARMING: Illegal cattle ranching is occurring in large areas of Brazil’s Arariboia territory, despite being prohibited on Indigenous lands across the country, a Mongabay investigation revealed. The investigation also found that killings of Guajajara Indigenous people inhabiting the region increased in mid-2023, coinciding with the construction of an unlicensed airstrip near the Buriticupu River. “Our research reveals a pattern of killings of indigenous Guajajara amid the expansion of cattle ranching and illegal logging in and around Arariboia,” Mongabay pointed out.
OTHER THREATS: Brazil’s Pantanal wetlands have already broken records for the number of fires this year, even before the technical start of the fire season, ABC News reported. Speaking to the press, environment minister Marina Silva attributed the fires to human activity, climate change and the prolonged effects of El Niño. At the same time, InfoAmazonia reported on research from the National Institute for Amazonian Research (INPA), which found that climate change has led to increasingly wetter and drier seasons in the city of Manaus, Brazil, at the confluence of the Negro and Amazon rivers. This poses a threat to the food security of riverine communities and has resulted in increased fish and dolphin deaths, the outlet said. It adds that the Amazon river recorded its lowest level since 1902 in October last year, yet it has also had “severe flooding with increasing frequency in recent years”.
AMAZON FORUM: A march by activists and Indigenous leaders from the nine countries of the Amazon region at the Pan-Amazon Social Forum (FOSPA) called for the defence of the Amazon, Inside Climate News reported. The marchers felt “disconnected” from international negotiations, such as the UN summits on climate change and biodiversity, and argued that government talks “have failed”, the article said. The four-day FOSPA meeting “is one of the few spaces for us to have our own dialogues”, said Vanuza Abacatal, the leader of the Quilombola community in Pará, Brazil. Inter Press Service added that those attending the forum agreed to continue defending Amazonian territories from deforestation and other extractive activities. A Pan-Amazonian women’s rights court was also held and revealed a systematic pattern of dispossession of territories suffered by women and their families, the article noted.
Agri climate impacts
KEY CROPS HIT: Extreme weather is delaying crop planting and impacting yields around the world, Reuters reported. “Vast swathes” of farmland in Russia, China, India and parts of the US recently experienced “extremely hot conditions and below-normal rainfall”, the outlet said. Low rainfall forecast for July and August in the “breadbasket” Black Sea region could “stunt sunflower and corn yields”, the newswire noted. Meanwhile, the Financial Times said that sales of olive oil “plunged” in parts of the Mediterranean due to “steep price rises”. The FT added: “Droughts and heatwaves exacerbated by climate change have knocked olive oil output in Spain, the world’s largest producer, as well as other major producing countries such as Italy and Greece, creating a global shortfall.”
INTENSE RAIN AND DROUGHTS: Thousands of agricultural workers are dealing with the aftermath of a “downpour that lasted a week” in El Salvador and other parts of Central America last month, the Inter Press Service reported. The region “suffers almost year after year from the onslaught of extreme rains or prolonged droughts”, the outlet said. One cattle rancher from El Salvador told the outlet that his herd declined from 150 to 40 in recent years due to heavy rainfall and other extremes. Meanwhile, the Guardian looked at the impact of drought on farmers in the Italian island of Sicily, where “the desert is encroaching” and rainfall has dropped by more than 40% since 2003.
WILTING: In India, recent extreme heat and rainfall impacted a range of crops, including flowers. Mongabay reported that flower vendors are selling less as “erratic rain and heat has led to damaged crops and produce being sold for a lesser price”. A flower seller told the outlet: “In recent years, with excessive rain on some days and regular exposure to water, the life span of flowers has reduced from two-three days to one day.” Context News reported on the “double blow” India’s intense heat has on fruit and vegetable sellers – “more of their produce is spoilt, while buyers stay at home and [are] ordering online”.
Spotlight
Denmark’s new agriculture tax
Last week, Denmark proposed plans for a world-first carbon tax on agriculture by 2030.
New Zealand recently scrapped similar plans for a so-called “burp tax” to cut livestock emissions.
In this spotlight, Carbon Brief explains this tax and what it will mean for Denmark’s climate targets. A full article on this topic will be published on Carbon Brief’s website later this week.
How will Denmark’s meat tax work?
Under the plans, landowners will pay a levy based on their emissions from livestock, fertiliser, forestry and the disturbance of carbon-rich agricultural soils, reports the Copenhagen Post.
The effective cost of the tax amounts to 120 Danish kroner (£14) per tonne of CO2 equivalent emitted from 2030, rising to 300 kroner (£34) from 2035 onwards. (As the British Agriculture Bureau explains, the actual costs are higher, but will be reduced by tax breaks.)
The proceeds “are to be pooled in a fund to support the livestock industry’s green transition for at least two years after the tax comes into effect”, says the Guardian.
The tax is just one element of a wider agreement on a “Green Denmark”. This was signed by a Green Tripartite, namely, a three-party agreement between the Danish government, the industry and agricultural sector, and conservation groups.
Danish economy minister Stephanie Lose said the agreement aims to form a “long-term basis for a historic reorganisation and transformation of Denmark’s land and of food and agricultural production”, reports Politico.
Under the agreement, Denmark will convert some agricultural lands to provide more space for nature and biodiversity. It also mandates that the country will set aside carbon-rich lowland soils, pursue afforestation and boost technologies and measures to cut emissions.
All these targets will be financed by a new Denmark’s Green Area Fund, which amounts to 40bn kroner (£4.6bn). Denmark’s government will also use EU agricultural subsidies for technology transition.
The Danish parliament still needs to approve the plan, but Reuters noted that “political experts expect a bill to pass following the broad-based consensus”.
How could this tax help Denmark meet its climate targets?
Agriculture is responsible for around a quarter of Denmark’s greenhouse gas emissions.
A “major part” of these emissions stem from livestock production, according to the country’s most recent national inventory report. The sector also accounts for more than 80% of methane and nitrous oxide emissions, the report says.
Denmark’s climate minister Lars Aagaard said in a statement that agriculture’s high emissions “cannot continue” and that a “great deal of work awaits” to implement the new agriculture measures.
The tax is expected to cut 1.8m tonnes of CO2 in 2030, Bloomberg reports. The proposals will help Denmark meet its 2030 climate goals and “take a big step closer to becoming climate neutral in 2045”, the tax minister Jeppe Bruus said in a statement.
Prof Søren Petersen, a soil microbiologist at Aarhus University in Denmark, agrees that the plan “could lead to substantial reductions in agricultural emissions” if implemented correctly. He tells Carbon Brief:
“It is my impression that there is a real interest in promoting climate-smart solutions and developing solutions that achieve real reductions in emissions.”
News and views
DEFORESTATION: EU politicians are “split” after calls to delay the bloc’s upcoming ban on imported goods that can be linked back to deforested land, Reuters reported. The law requiring “companies and traders placing beef, coffee, palm oil and other products on the EU market to prove their supply chains do not contribute to the destruction of forests” is due to take effect this year, Reuters said. Last week, the European People’s Party environment spokesperson, Peter Liese, called for the law to be delayed and scaled back, describing it as a “bureaucratic monster”. Other EU political parties, including the Socialists & Democrats and the Greens, oppose a delay, Reuters said. The US recently asked the EU to postpone the law, a separate Reuters article noted, joining previous calls from Malaysia and Indonesia.
CONSERVATIONISTS’ PROTESTS: Local and international conservation organisations protested that the Republic of Congo’s Conkouati-Douli national park could be at risk after a Chinese company received an oil and gas exploration licence, according to Down to Earth. Conservationists said the exploration permit would damage the environmental health of “the country’s most biodiverse protected area”, home to endangered species such as the western lowland gorilla and forest elephant, and around 7,000 people “whose livelihoods are dependent on the forest”. They criticised that the decision came after the Congolese government signed a $50m forest protection agreement at last year’s COP28.
MARCH FOR NATURE: Thousands of people marched in London on 22 June to “urge” politicians to tackle the UK’s “wildlife crisis”, the Guardian reported. A rally held after the march heard from naturalist Chris Packham and musician Billy Bragg, the newspaper said, adding that actor Emma Thompson also called on politicians to “act now” on climate change. The Wildlife Trusts, one of the charities supporting the march, claimed that more than 60,000 people attended, urging UK political parties to “restore nature now”. The Guardian noted: “Protesters were calm but the placards they held up revealed an undercurrent of frustration and anger.” (UK voters will cast their ballots in a general election tomorrow.)
CHINESE FERTILISERS: China is imposing restrictions on fertiliser exports, especially urea and phosphates, risking a global price surge for essential crop nutrients, Bloomberg reported. The outlet noted that the Chinese government is protecting the domestic grain market due to the threat of extreme weather events impacting crop production and other challenges faced by farmers – including low grain prices and increased costs. Bloomberg added that in 2023 China was the world’s top exporter of both urea and the most used phosphate.
US OLD-GROWTH FORESTS: The US government advanced plans to “restrict logging within old-growth forests that are increasingly threatened by climate change”, the Associated Press reported. The newswire explained that there will be exceptions for tree-cutting to reduce wildfire risks. A government press release labelled the plan as “the most ambitious climate and conservation agenda in history”. The proposed amendment to 128 forest land management plans would use science and Indigenous knowledge to guide conservation and restoration efforts of old-growth forests. These ecosystems offset more than 10% of US annual greenhouse gas emissions and comprise 32m acres, according to the White House.

SAHEL PLAN: A Deutsche Welle video discussed progress on Africa’s “Great Green Wall” project, which was “designed to stop land degradation and desertification”.
RIGHTS: During pride month in June, Dialogue Earth interviewed Aurélien Guilabert, a Mexico City-based activist focused on “both LGBTQ+ rights and environmental protection”.
RISING TIDES: The New York Times spoke to scientists and officials in the Maldives to understand how low-lying tropical islands have not yet been lost to rising sea levels and how “some have even grown”.

New science
Frontiers in Science
Protecting just 1.2% of the world’s land could save the most rare and threatened species from extinction, a study found. The researchers compared data identifying areas with rare and endangered species with current protected area maps to identify unprotected lands. They found that 16,825 of these unprotected sites around the world should be “prioritised for conservation action over the next five years as part of a broader strategy to expand the global protected area network”. They estimated that it would cost $29-46bn annually over the next five years to conserve these “last unprotected sites harbouring rare, range-restricted and threatened species”.
Ecological disturbance alters the adaptive benefits of social ties
Science
Monkeys became less aggressive and more tolerant towards each other after an intense hurricane in Puerto Rico, according to new research. Hurricane Maria hit the north-eastern Caribbean in 2017, killing almost 3,000 people in Puerto Rico. The hurricane also led to “persistent deforestation”, which reduced shade cover and increased animal “exposure to intense heat”, the study said. The researchers looked at a decade of data on rhesus macaques, a species of monkey, on a small island off the coast of Puerto Rico before and after the hurricane to assess any social behaviour changes. They found that the monkeys showed “persistently increased tolerance and decreased aggression toward other monkeys, facilitating access to scarce shade critical for thermoregulation”.
Threat of low-frequency high-intensity floods to global cropland and crop yields
Nature Sustainability
New research highlighted the “urgency” of protecting cropland in “neglected” areas that experience low-frequency, but high-impact floods. Using satellite imagery and data for 3,427 flood events around the world over 2000-21, the researchers found that flooding affected a larger proportion of cropland area in low-frequency flood areas (4.7%) compared to high-frequency flood areas (1.2%). In addition, the study found that the average losses of wheat and rice were greater in low-frequency flood areas, owing to “the higher precipitation anomalies, soil moisture anomalies and greater crop flooding during their growing seasons”.

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.
The Great Power Shift is a new campaign by 350.org global campaign to pressure governments to bring down energy bills for good by ending fossil fuel dependence and investing in clean, affordable energy for all

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.
