Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Preparing for 3C
NEW ALERT: The EU’s climate advisory board urged countries to prepare for 3C of global warming, reported the Guardian. The outlet quoted Maarten van Aalst, a member of the advisory board, saying that adapting to this future is a “daunting task, but, at the same time, quite a doable task”. The board recommended the creation of “climate risk assessments and investments in protective measures”.
‘INSUFFICIENT’ ACTION: EFE Verde added that the advisory board said that the EU’s adaptation efforts were so far “insufficient, fragmented and reactive” and “belated”. Climate impacts are expected to weaken the bloc’s productivity, put pressure on public budgets and increase security risks, it added.
UNDERWATER: Meanwhile, France faced “unprecedented” flooding this week, reported Le Monde. The flooding has inundated houses, streets and fields and forced the evacuation of around 2,000 people, according to the outlet. The Guardian quoted Monique Barbut, minister for the ecological transition, saying: “People who follow climate issues have been warning us for a long time that events like this will happen more often…In fact, tomorrow has arrived.”
IEA ‘erases’ climate
MISSING PRIORITY: The US has “succeeded” in removing climate change from the main priorities of the International Energy Agency (IEA) during a “tense ministerial meeting” in Paris, reported Politico. It noted that climate change is not listed among the agency’s priorities in the “chair’s summary” released at the end of the two-day summit.
US INTERVENTION: Bloomberg said the meeting marked the first time in nine years the IEA failed to release a communique setting out a unified position on issues – opting instead for the chair’s summary. This came after US energy secretary Chris Wright gave the organisation a one-year deadline to “scrap its support of goals to reduce energy emissions to net-zero” – or risk losing the US as a member, according to Reuters.
Around the world
- ISLAND OBJECTION: The US is pressuring Vanuatu to withdraw a draft resolution supporting an International Court of Justice ruling on climate change, according to Al Jazeera.
- GREENLAND HEAT: The Associated Press reported that Greenland’s capital Nuuk had its hottest January since records began 109 years ago.
- CHINA PRIORITIES: China’s Energy Administration set out its five energy priorities for 2026-2030, including developing a renewable energy plan, said International Energy Net.
- AMAZON REPRIEVE: Deforestation in the Brazilian Amazon has continued to fall into early 2026, extending a downward trend, according to the latest satellite data covered by Mongabay.
- GEZANI DESTRUCTION: Reuters reported the aftermath of the Gezani cyclone, which ripped through Madagascar last week, leaving 59 dead and more than 16,000 displaced people.

Captured
Repealing the US’s landmark “endangerment finding”, along with actions that rely on that finding, will slow the pace of US emissions cuts, according to Rhodium Group visualised by Carbon Brief. US president Donald Trump last week formally repealed the scientific finding that underpins federal regulations on greenhouse gas emissions, although the move is likely to face legal challenges. Data from the Rhodium Group, an independent research firm, shows that US emissions will drop more slowly without climate regulations. However, even with climate regulations, emissions are expected to drop much slower under Trump than under the previous Joe Biden administration, according to the analysis.
Spotlight
How a ‘tree invasion’ helped to fuel South America’s fires
This week, Carbon Brief explores how the “invasion” of non-native tree species helped to fan the flames of forest fires in Argentina and Chile earlier this year.
Since early January, Chile and Argentina have faced large-scale and deadly wildfires, including in Patagonia, which spans both countries.
These fires have been described as “some of the most significant and damaging in the region”, according to a World Weather Attribution (WWA) analysis covered by Carbon Brief.
In both countries, the fires destroyed vast areas of native forests and grasslands, displacing thousands of people. In Chile, the fires resulted in 23 deaths.
Multiple drivers contributed to the spread of the fires, including extended periods of high temperatures, low rainfall and abundant dry vegetation.
The WWA analysis concluded that human-caused climate change made these weather conditions at least three times more likely.
According to the researchers, another contributing factor was the invasion of non-native trees in the regions where the fires occurred.
The risk of non-native forests
In Argentina, the wildfires began on 6 January and persisted until the first week of February. They hit the city of Puerto Patriada and the Los Alerces and Lago Puelo national parks, in the Chubut province, as well as nearby regions.
In these areas, more than 45,000 hectares of native forests – such as Patagonian alerce tree, myrtle, coigüe and ñire – along with scrubland and grasslands, were consumed by the flames, according to the WWA study.
In Chile, forest fires occurred from 17 to 19 January in the Biobío, Ñuble and Araucanía regions.
The fires destroyed more than 40,000 hectares of forest and more than 20,000 hectares of non-native forest plantations, including eucalyptus and Monterey pine.
Dr Javier Grosfeld, a researcher at Argentina’s National Scientific and Technical Research Council (CONICET) in northern Patagonia, told Carbon Brief that these species, introduced to Patagonia for production purposes in the late 20th century, grow quickly and are highly flammable.
Because of this, their presence played a role in helping the fires to spread more quickly and grow larger.
However, that is no reason to “demonise” them, he stressed.
Forest management
For Grosfeld, the problem in northern Patagonia, Argentina, is a significant deficit in the management of forests and forest plantations.
This management should include pruning branches from their base and controlling the spread of non-native species, he added.
A similar situation is happening in Chile, where management of pine and eucalyptus plantations is not regulated. This means there are no “firebreaks” – gaps in vegetation – in place to prevent fire spread, Dr Gabriela Azócar, a researcher at the University of Chile’s Centre for Climate and Resilience Research (CR2), told Carbon Brief.
She noted that, although Mapuche Indigenous communities in central-south Chile are knowledgeable about native species and manage their forests, their insight and participation are not recognised in the country’s fire management and prevention policies.
Grosfeld stated:
“We are seeing the transformation of the Patagonian landscape from forest to scrubland in recent years. There is a lack of preventive forestry measures, as well as prevention and evacuation plans.”

Thousands of People Say Roundup Caused Their Cancer. The Supreme Court May Quash Their Lawsuits.
The case centers around the regulation of glyphosate, the world’s most commonly used herbicide, which researchers have linked to health problems in both animals and people.
John Durnell just wanted to make things around his St. Louis neighborhood look a little nicer. So, on occasion, he’d spray a bit of Roundup in the obvious places—along weedy sidewalks and in public spaces he thought needed a little extra attention.

In the global fight against catastrophic, human-induced climate change, diplomacy plays a vital role.
Historic initiatives like the Paris Agreement and the Fund for Responding to Loss and Damage were the consequence of tireless, coordinated international efforts of states, civil society and scientists. The role of COP, and other summits like it, remains key. However, they are coming under increasing pressure.
Last year the climate COP30 was unable to take a decision on fossil fuels, despite calls from over 80 states, as well as children and youth, medical professionals, Indigenous peoples and climate justice movements. A landmark deal to cut global shipping emissions was put on ice and global talks to develop a much-needed treaty to end plastic pollution were stalled by a few states who wish to avoid even mentioning fossil fuels in international negotiations.

Sixty countries head to Santa Marta to cement coalition for fossil fuel transition
After last year’s COP30 disappointment, governments will seek a renewed push to phase out fossil fuels at the first global summit on the theme in Colombia -
Prospects for global green shipping deal boosted by US tariff ruling, analysts say
While divisions remain over the international shipping’s Net Zero Framework, the US’s main threat may now have been partly neutered
In these instances, the process of building consensus was hijacked by actors whose priorities lie in the continued exploration and production of fossil fuels, magnifying the views of a handful of powerful states at the expense of all others.
In recent months, illegal aggressions in Venezuela and Iran, armed conflicts, political turbulence and economic instability have conspired to make international cooperation harder. At the same time, the impact our reliance on fossil fuels and petrochemical fertilisers has on the cost of living, energy and food insecurity has been laid bare.
Against this backdrop, a new idea was born at COP30: the First Conference on Transitioning Away from Fossil Fuels, which the Colombian government is co-hosting with the Netherlands in Santa Marta this week.
Inclusion and implementation
It represents the possibility of a new kind of multilateral forum: one that foregrounds the voices of those most impacted by the climate crisis and is relentlessly focused on implementation. It is only open to states that wish to make progress and discuss how – not if – to move away from fossil fuel dependency. And it is set to draw on the insights of Indigenous peoples, Afro-descendants and peasants, civil society, cities and academics, women and youth, who are often left out of international negotiating rooms.
The talks centre on how to ensure that the transition away from fossil fuels is also a just one: a transition that protects workers, communities and the environment, respects human rights and builds public legitimacy, rather than imposing new costs on those least responsible for the crisis.
To phase out fossil fuels, developing countries need exit route from “debt trap”
The conference is also unpacking how international cooperation must work for countries and communities facing fiscal dependence, debt burdens and limited implementation capacity. It aims to identify the financial and technological support required from the Global North to allow other countries to leapfrog into sustainable renewables-based economies.
In addition, it will seek to address the harmful international legal barriers – such as the thousands of international investment agreements which include investor–state dispute settlement (ISDS) provisions – that allow foreign corporations to sue states for measures adopted in the public interest.
Solutions that tackle injustice
These are complex, but necessary conversations to be had for all governments. Most international fora are being used to “avoid the conversation”. We have many of the solutions, but we need to ensure they’re implemented in ways that benefit all countries and sectors of society, not just a few.
Santa Marta aims to strengthen a “coalition” of ambitious states, who are responsive to the voices of those most affected by climate change. It also aims to mobilise scientists, lawyers, economists, policy and energy experts, and the medical community to support states, as well as cities and citizen initiatives to pilot promising approaches around the world. Through a deeply inclusive and participatory approach, at every level, Santa Marta can pave the way towards solutions that are co-developed and respond directly to what’s needed on the ground.
New panel of climate scientists calls for fossil fuel transition roadmaps
This will be key for achieving a just transition. Many countries, especially in the Global South, are not held back by a lack of ambition, but by structural barriers: debt, high borrowing costs and international rules that still reward continued fossil fuel extraction over managed decline at the expense of people’s health and economic well-being.
Santa Marta comes at a critical moment: environmentally, morally, economically but also legally.
Legal accountability on fossil fuels
The landmark advisory opinion on climate change, issued last July by the International Court of Justice, made clear that states have a legal obligation to act effectively and ambitiously on climate change, and that fossil fuel expansion, production, consumption and subsidies are not in line with these international obligations. It followed similar rulings, by the International Tribunal for the Law of the Sea in 2024 and the Inter-American Court of Human Rights, also in 2025.
The transition away from fossil fuels is not simply an environmental necessity, but an urgent matter of security, resilience and health. It is a human rights imperative. And an inherently exclusionary approach focused on major powers will not deliver all the benefits of a fossil fuel-free global economy.
Vanuatu pursues new UN resolution to turn ICJ climate opinion into action
The Santa Marta conference is set to address this and look at how fossil-fuel-dependent countries can diversify on fair terms, how communities can access and produce affordable and reliable renewable energy, and how the transition can deliver visible social and economic gains instead of reproducing new forms of exclusion, dependency, and insecurity.
At Santa Marta we can make meaningful, lasting progress through a diplomacy of implementation, inclusion and legal accountability that can provide a new yardstick for all the other multilateral processes on climate change and other fossil fuel-related issues, such as plastics, food, health, taxation and the protection of peace.
