Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Fire and ice
OZ HEAT: The ongoing heatwave in Australia reached record-high temperatures of almost 50C earlier this week, while authorities “urged caution as three forest fires burned out of control”, reported the Associated Press. Bloomberg said the Australian Open tennis tournament “rescheduled matches and activated extreme-heat protocols”. The Guardian reported that “the climate crisis has increased the frequency and severity of extreme weather events, including heatwaves and bushfires”.
WINTER STORM: Meanwhile, a severe winter storm swept across the south and east of the US and parts of Canada, causing “mass power outages and the cancellation of thousands of flights”, reported the Financial Times. More than 870,000 people across the country were without power and at least seven people died, according to BBC News.
COLD QUESTIONED: As the storm approached, climate-sceptic US president Donald Trump took to social media to ask facetiously: “Whatever happened to global warming???”, according to the Associated Press. There is currently significant debate among scientists about whether human-caused climate change is driving record cold extremes, as Carbon Brief has previously explained.
Around the world
- US EXIT: The US has formally left the Paris Agreement for the second time, one year after Trump announced the intention to exit, according to the Guardian. The New York Times reported that the US is “the only country in the world to abandon the international commitment to slow global warming”.
- WEAK PROPOSAL: Trump officials have delayed the repeal of the “endangerment finding” – a legal opinion that underpins federal climate rules in the US – due to “concerns the proposal is too weak to withstand a court challenge”, according to the Washington Post.
- DISCRIMINATION: A court in the Hague has ruled that the Dutch government “discriminated against people in one of its most vulnerable territories” by not helping them to adapt to climate change, reported the Guardian. The court ordered the Dutch government to set binding targets within 18 months to cut greenhouse gas emissions in line with the Paris Agreement, according to the Associated Press.
- WIND PACT: 10 European countries have agreed a “landmark pact” to “accelerate the rollout of offshore windfarms in the 2030s and build a power grid in the North Sea”, according to the Guardian.
- TRADE DEAL: India and the EU have agreed on the “mother of all trade deals”, which will save up to €4bn in import duty, reported the Hindustan Times. Reuters quoted EU officials saying that the landmark trade deal “will not trigger any changes” to the bloc’s carbon border adjustment mechanism.
- ‘TWO-TIER SYSTEM’: COP30 president André Corrêa do Lago believes that global cooperation should move to a “two-speed system, where new coalitions lead fast, practical action alongside the slower, consensus-based decision-making of the UN process”, according to a letter published on Tuesday, reported Climate Home News.

Captured
Sales of electric vehicles (EVs) overtook standard petrol cars in the EU for the first time in December 2025, according to new figures released by the European Automobile Manufacturers’ Association (ACEA) and covered by Carbon Brief. Registrations of “pure” battery EVs reached 217,898 – up 51% year-on-year from December 2024. Meanwhile, sales of standard petrol cars in the bloc fell 19% year-on-year, from 267,834 in December 2024 to 216,492 in December 2025, according to the analysis.
Spotlight
Looking at climate visuals
Carbon Brief’s Ayesha Tandon recently chaired a panel discussion at the launch of a new book focused on the impact of images used by the media to depict climate change.
When asked to describe an image that represents climate change, many people think of polar bears on melting ice or devastating droughts.
But do these common images – often repeated in the media – risk making climate change feel like a far-away problem from people in the global north? And could they perpetuate harmful stereotypes?
These are some of the questions addressed in a new book by Prof Saffron O’Neill, who researches the visual communication of climate change at the University of Exeter.
“The Visual Life of Climate Change” examines the impact of common images used to depict climate change – and how the use of different visuals might help to effect change.
At a launch event for her book in London, a panel of experts – moderated by Carbon Brief’s Ayesha Tandon – discussed some of the takeaways from the book and the “dos and don’ts” of climate imagery.
Power of an image
“This book is about what kind of work images are doing in the world, who has the power and whose voices are being marginalised,” O’Neill told the gathering of journalists and scientists assembled at the Frontline Club in central London for the launch event.
O’Neill opened by presenting a series of climate imagery case studies from her book. This included several examples of images that could be viewed as “disempowering”.
For example, to visualise climate change in small island nations, such as Tuvalu or Fiji, O’Neill said that photographers often “fly in” to capture images of “small children being vulnerable”. She lamented that this narrative “misses the stories about countries like Tuvalu that are really international leaders in climate policy”.
Similarly, images of power-plant smoke stacks, often used in online climate media articles, almost always omit the people that live alongside them, “breathing their pollution”, she said.
During the panel discussion that followed, panellist Dr James Painter – a research associate at the Reuters Institute for the Study of Journalism and senior teaching associate at the University of Oxford’s Environmental Change Institute – highlighted his work on heatwave imagery in the media.
Painter said that “the UK was egregious for its ‘fun in the sun’ imagery” during dangerous heatwaves.
He highlighted a series of images in the Daily Mail in July 2019 depicting people enjoying themselves on beaches or in fountains during an intense heatwave – even as the text of the piece spoke to the negative health impacts of the heatwave.
In contrast, he said his analysis of Indian media revealed “not one single image of ‘fun in the sun’”.
Meanwhile, climate journalist Katherine Dunn asked: “Are we still using and abusing the polar bear?”. O’Neill suggested that polar bear images “are distant in time and space to many people”, but can still be “super engaging” to others – for example, younger audiences.
Panellist Dr Rebecca Swift – senior vice president of creative at Getty images – identified AI-generated images as “the biggest threat that we, in this space, are all having to fight against now”. She expressed concern that we may need to “prove” that images are “actually real”.
However, she argued that AI will not “win” because, “in the end, authentic images, real stories and real people are what we react to”.
When asked if we expect too much from images, O’Neill argued “we can never pin down a social change to one image, but what we can say is that images both shape and reflect the societies that we live in”. She added:
“I don’t think we can ask photos to do the work that we need to do as a society, but they certainly both shape and show us where the future may lie.”
Watch, read, listen
UNSTOPPABLE WILDFIRES: “Funding cuts, conspiracy theories and ‘powder keg’ pine plantations” are making Patagonia’s wildfires “almost impossible to stop”, said the Guardian.
AUDIO SURVEY: Sverige Radio has published “the world’s, probably, longest audio survey” – a six-hour podcast featuring more than 200 people sharing their questions around climate change.

DeBriefed 30 January 2026: Fire and ice; US formally exits Paris; Climate image faux pas
One of the key expected outcomes from the upcoming COP31 climate summit in Antalya, Turkey, is the launch of a “just transition mechanism”.
This follows years of calls from civil society to support a “just transition” as countries shift towards low-emissions energy systems and away from fossil fuels.
At the COP30 UN climate talks last year in the Brazilian city of Belém parties agreed to establish a “mechanism” to support this goal, called the “Belém-Antalya mechanism” (BAM).
Groups that have championed the BAM want it to act as a central hub on just transitions, providing support for workers and communities around the world.
However, the details of exactly what the much-touted BAM will consist of remain vague, with developed and developing countries disagreeing about its functions and purpose.
Disagreements continued at the UN climate talks in Bonn in June 2026, including on the crucial question of how the BAM will be financed.
Here, Carbon Brief looks at where the idea for the BAM came from, how it could support just transitions and what to expect from COP31.
How has a ‘just transition’ featured in UN climate talks?
A “just transition” is the idea that workers and communities should be supported in the shift to a low-carbon economy. It is a central principle behind the idea of climate justice.
Often, the term refers to those linked to the fossil-fuel industry, but it can also refer to transitions taking place in agriculture, heavy industry and various other sectors.
The concept originated in the 1980s, when US labour unions forged alliances with environmental justice groups. It has since become a key part of international climate discussions.
The preamble to the 2015 Paris Agreement includes a commitment to “tak[e] into account the imperatives of a just transition of the workforce and the creation of decent work and quality jobs in accordance with nationally defined development priorities”.
Bert De Wel, policy officer at the International Trade Union Confederation (ITUC), tells Carbon Brief:
“The labour movement is very happy with the wide audience and broad political support that the concept has received since its inception in the 1980s. The inclusion in the Paris Agreement, with the reference to the creation of decent work and quality jobs was a milestone for the movement. While other demands have been added…we continue to stress the labour dimension as being central to the concept.”
Three years after the creation of the Paris Agreement, at COP24 in the former coal-mining city of Katowice, the Polish presidency highlighted the issue of just transitions.
The need for carbon-cutting policies to ensure “a just transition of the workforce” that creates “decent work and quality jobs” was included in the “Silesia declaration”, issued by the presidency during the first week of COP24.
While the declaration was only signed by 50 countries – roughly a quarter of the parties at the summit – it was still “noted” in the final COP text.
This helped to drive momentum behind the idea, culminating in formal agreement at COP27 in Egypt to launch a “work programme on just transition” (JTWP).
De Wel says the establishment of the JTWP was a “major step forward” that allowed parties to “speak about just transition in more concrete terms”.
In the years since, negotiators have worked to flesh out the JTWP, with disagreements between parties about what its purpose should be.
Broadly, developed countries would like it to focus on domestic workforces, while some nations want a more global outlook, including support for transitions in developing countries.
The JTWP has proved a challenging negotiating space, with talks at the COP29 summit in 2024 closing without an agreement, in what one observer dubbed a “betrayal”.
However, despite these frustrations, parties at COP30 in Brazil agreed to establish a new institutional mechanism on just transitions, which has become widely known as the BAM. The move was hailed as a “victory” by civil society.
Where did the ‘just transition mechanism’ come from?
In the run-up to COP30, civil society began to push for the establishment of an “institutional arrangement” that would move work under the JTWP from talk into action.
(This was originally called the “Belém action mechanism” by civil society groups, who subsequently updated this to the “Belém-Antalya mechanism” following the outcome at COP30. However, in the JTWP text agreed at COP30 it is only described as a “mechanism”, sometimes also referred to as the “just transition mechanism”.)
Anabella Rosemberg, senior advisor on just transition at NGO umbrella group Climate Action Network (CAN) International, tells Carbon Brief:
“The idea of the mechanism emerged from the collaboration of civil society, trade unions, feminist groups, youth and Indigenous peoples in the UNFCCC.
“It was clear that the kind of activities being run under the JTWP – two dialogues a year and one ministerial – would not support the delivery of just-transition strategies on the ground, so a new approach was developed to get words into action.”
Following the inception of the idea, civil society did “tonnes of stuff to boost it up the agenda”, Dr Leon Sealey-Huggins, a senior campaigner at the charity War on Want, tells Carbon Brief.
This ranged from presenting demands and proposals to different constituents, organising joint letters and writing policy papers, all the way through to designing logos, creating memes and even a song.
These efforts ultimately paid off: during the Bonn climate negotiations in June 2025, one draft text included the idea for a new institutional arrangement. One of the options in the draft text was for a “toolbox, guidance framework, global platform, technical assistance network [or] mechanism”.
![Paragraph 28 of the JTWP text published 25 June 2025. The text reads "28. Options for further implementation of the United Arab Emirates just transition work programme Option 1: Improving existing modalities Option 2: New institutional arrangements [toolbox, guidance framework, global platform, technical assistance network, mechanism] Option 3: Defer decision to 2026"](https://www.carbonbrief.org/wp-content/uploads/2026/11/para28-1024x334.png)
This inclusion was broadly welcomed as a “big win” for civil society groups, although parties acknowledged that more needed to be done to flesh out the idea.
Going into COP30, civil society groups continued to push the idea of creating a BAM, with protests, banners and badges visible around the venue.
Early in negotiations, the G77 and China – a large coalition of developing countries at UN climate talks – put forward their own proposal for a just transition “mechanism”. This, they suggested, could provide technical assistance, support international cooperation and help to foster partnerships in an effort to address implementation gaps.
Their proposal faced initial pushback from developed-country parties including Norway, the UK and others, who opposed it due to concerns that it would duplicate existing systems and require additional funding.
Developed countries also opposed the use of the term “mechanism”, with the EU suggesting an “action plan” as a potential alternative. Nevertheless, the creation of a “mechanism” was included in the final draft text on the JTWP.
This text was formally approved during the COP30 closing plenary to extended applause from many in the hall.
In a statement at the time, Chiara Martinelli, director at CAN Europe, welcomed the decision:
“Delivering BAM was a major civil society win. It creates a coordinated institutional home to drive forward progress on the just transition.”
The decision to develop the mechanism included a request for parties to work over the subsequent year – through to COP31 – on a plan to get things started.
What role could the mechanism play in facilitating ‘just transitions’?
According to civil society, the BAM could help tackle the fractured just-transition landscape by centralising resources and helping to overcome a number of barriers.
Speaking to Carbon Brief, Rosemberg says the just-transition space “lacks coordination and the right kind of support and is quite disconnected from climate action imperatives”. She adds:
“The BAM can play a role in bringing those [people] trying to make just transition happen together, identify gaps and barriers, foster cooperation and accelerate support.”
Civil society has put forward a number of proposals likely to inform the structure of the BAM. Most consist of a mechanism with three parts, which would encompass and expand upon the work that is currently being carried out under the JTWP.
One proposal by a coalition of five NGOs suggests the mechanism is formed of a steering body, a “knowledge arm” and an “implementation arm”.
The steering body would coordinate the work of the two arms of the BAM, including deciding the topics that should be discussed under the ongoing JTWP, which will continue to feature in climate negotiations. They suggest the body would recommend topics that require negotiation when “gaps that require political guidance are identified”.
Their proposal is illustrated in the infographic below, showing the steering body acting as a central hub for work within the BAM.
