Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Africa’s second climate summit
‘NOT CHARITY’: At the second Africa climate summit held in Addis Ababa in Ethiopia this week, leaders “chastised developed nations for failing to honor [climate finance] pledges” and said they will “tap the private sector” to help fill the gap, Bloomberg reported. In a joint statement, African leaders said that providing climate finance is “a legal obligation and not charity, as anchored in the UN Framework Convention on Climate Change and its Paris Agreement”, according to the outlet.
SOLUTIONS CENTRED: Climate Home News reported that Ethiopian president Taye Atske Selassie told the closing ceremony on Wednesday the summit had repositioned Africa “not as victims of a crisis it never created but as a global centre for climate solution, renewable energy and green growth”. The outlet added that the joint leaders’ declaration called for “strengthened and sustained support” to scale up African-led climate initiatives, such as the 8,000km Great Green Wall across the Sahel and the African Forest Landscape Restoration Initiative.
Around the world
- ‘SILLY’: Chris Wright, the climate-sceptic US energy secretary, has dismissed the impacts of climate change as “not incredibly important” and described the Paris Agreement as “silly”, reported the New York Times. Elsewhere, the group of “climate contrarians” behind Trump’s misleading climate report have been “disbanded” following a lawsuit challenging their appointment, CNN reported.
- CHINA BOOM: The world’s fossil-fuel use could begin to drop by 2030 as a result of China’s “rapid adoption of renewables and its increasing reliance on electricity”, Bloomberg reported, citing a new study by thinktank Ember.
- NDC INDECISION: EU member states are still “wrangling” over the bloc’s overdue 2035 climate target, “with no sign of agreement”, according to a leaked draft text seen by the Guardian.
- TRADE SPOTLIGHT: Brazil plans to propose a new forum for governments to discuss how climate policy affects trade at the next World Trade Organization meeting next week, according to Reuters.
- UK PUBLIC POLLED: In a frontpage story, the Times covered new polling it commissioned, reporting that the number of people who think the dangers of global warming are exaggerated has increased by more than 50% in the past four years, from 16% to 25%. [Polling experts have criticised the framing of the Times coverage, noting that a large majority of the public still back net-zero.]
£797 million
The record amount of UK climate aid spent on nature last year – largely due to an increase in spending on carbon offsets, according to new Carbon Brief analysis.

Captured
A new study used “extreme event attribution” to assess the impact of climate change on all 21st-century heatwaves that were classified as “major disasters”. It found that global warming linked to the world’s biggest 180 oil and gas companies made all 213 heatwaves analysed more intense and frequent. Meanwhile, one-quarter of the heatwaves would have been “virtually impossible” without human-caused global warming. The paper, covered by Carbon Brief, analysed 213 heatwaves over 2000-23 that were recorded in the EM-DAT database of “major disasters” . These heatwaves are shown in the map above.

How scientists can tackle net-zero backlash
This week, Carbon Brief asks climate scientists attending a summit at the University of East Anglia, UK how researchers can better combat net-zero misinformation.
It comes as the UK’s right-wing political parties and press are increasingly making misleading claims about net-zero.
Asher Minns, executive director of the Tyndall Centre for Climate Change Research at the University of East Anglia
The whole discourse around net-zero has become something that it was never intended to be. It’s a quite specific scientific concept that came out of the IPCC 1.5C report, following up on [the] Paris [Agreement], so it actually has quite a specific definition, but it has actually become a phrase that is being used really just to mean “removing CO2” or “saving energy”, even. It’s become this kind of huge term across public, across media, across policy, that everybody can just pin what they mean to “net-zero” without actually referring to what it actually is, which is absolute zero emissions, getting CO2 out of the atmosphere. The fact that there is a government department called “net-zero” isn’t great for that public discourse, for public understanding, and that’s why we’ve got a bit of a backlash. I don’t think we need to necessarily abandon the phrase net-zero, but I think we should just talk about clean energy and concepts that people have a chance of hanging onto, rather than something that’s really quite difficult.
Prof Corinne Le Quéré, Royal Society research professor of climate change science at the University of East Anglia
I think narratives about the way that we present climate action can be very negative, and, in fact, we do climate action all the time. We’ve cut emissions by half in the UK and most people haven’t realised that this is happening. Just talking about climate change in the way that there are things that you can do that are desirable and have benefits for you. Of course, the government needs to make climate solutions accessible to everybody. But improving the narratives about how we talk about climate change, that would be, for me, a small thing that we could do.
Prof Hayley Fowler, professor of climate change impacts at Newcastle University
I don’t think we can do it alone. I think we try to do everything alone and I don’t think that’s the right approach. My personal opinion is we need to be collaborating with key influencers and celebrities, quite honestly, who can actually get that message across to the people who need to hear that message. I think we need probably a few key spokespeople. And I don’t think they should be scientists, but they should have simple and clear scientific messages that they convey. There’s lots of misinformation and it’s conveyed in very clear ways with simple messaging. Often climate science is really, really complicated and that’s why people just don’t understand it, they don’t understand the jargon surrounding it and, therefore, perhaps they are more likely to understand the simple messages that come from the climate deniers.
Dr Ruth Wood, senior lecturer in environment and climate change at the University of Manchester
I find it quite challenging to work out how to engage in those discussions because they’re taking place in forums that I’m not at. Do we need a groundswell of voices around supporting net-zero, which have the same level of media savviness of the anti net-zero groups? If we had their same ability to mobilise and get the message out there, maybe that would counter some of their narratives. The gap between science and communication is a huge challenge.
Prof Charlie Wilson, professor of energy and climate change and senior research fellow in the Environmental Change Institute at the University of Oxford
I guess that part of the answer is how we’ve always done it, which is forceful rebuttals and corrections with appropriate evidence. The second bit is like learning how the algorithms work to promote both information, as well as misinformation. This misinformation is being amplified by algorithmic preferences expressed through social media platforms, which emphasise juicy clickbait-type stuff.

Three countries have been named by the Paris Agreement’s compliance committee for failing to submit a nationally determined contribution (NDC) and repeatedly snubbing offers of help with their climate plans.
After months of internal debate over whether to identify serial non-responders, the Paris Agreement’s Implementation and Compliance Committee (PAICC) named the three countries which have failed to engage with it over their NDCs on Friday.
It named Democratic Republic of Congo, Senegal and North Korea in a footnote of its annual report, adding that it decided to name them “with a view to facilitating engagement”, adding that representatives of the three nations had been invited to its meeting in early 2027 “with the purpose of identifying any challenges and constraints”.
“The Committee noted the importance of Parties engaging with the Committee in a timely manner, while noting that some delays may be due to the national capabilities and circumstances of the Parties”, the report said.

Paris Agreement committee snubbed over missing NDC climate plans
Many governments have still not submitted a nationally determined contribution to the UN, breaching a key requirement of the Paris Agreement
In July, PAICC said 12 countries had ignored its repeated attempts to discuss why they had not published an NDC as required every five years under the 2015 Paris accord.
Members of the committee had been divided over whether to name them, but at a September meeting decided to do so in their annual report to the annual climate COP summit.
By the time the report was published on Friday, only Congo, Senegal and North Korea “had not communicated an NDC or submitted a [Biennial Transparency Report] and had not yet responded to any of the Committee’s notifications, despite several reminders issued by the Committee in this regard”.
Rainforest and renewable energy ambitions
The silence from Congo and Senegal is notable because the former is home to much of the Congo Basin rainforest while the latter has sought billions of dollars in climate finance to support its renewable energy ambitions.
After Brazil, Congo has more rainforest than any country in the world. This forest, and the country’s peatlands, absorb huge amounts of greenhouse gas but are fast being lost to expanding farmland, charcoal production, logging and mining.
Senegal signed a Just Energy Transition Partnership with Canada and wealthy European nations in 2023, to help it meet its renewable energy targets under the-then government of Macky Sall. It was chair of the Least Developed Countries group between January 2022 and December 2023.
Tejas Rao, who is researching the PAICC as part of a doctoral thesis at Cambridge University, said the governments of the three countries should engage with the committee.
“Engagement costs these governments very little and the committee has shown it will listen,” he said.
“Silence leaves the committee with no basis to help, and it leaves the [governments] exposed to the narrative that they are simply disengaged,” he told Climate Home News.
Paris Agreement requirement
The 2015 Paris Agreement requires all parties to publish an NDC every five years outlining their emissions reduction targets, with each plan meant to be more ambitious than the country’s last NDC.
The latest set – the third round of plans, with new targets for 2035 – was due in February 2025. While most countries missed this deadline, all but around 30 – mostly small emitters but including Egypt, Vietnam and Argentina – have now submitted them.
Over the year, the PAICC – which is made up of government climate officials from developed and developing countries – has been communicating with governments that have not submitted NDCs and trying to overcome barriers to them doing so.
Some nations have cited exceptional circumstances as the reason for not submitting an NDC, a process that requires a significant amount of work in tracking emissions and consulting on how to curb them across the economy. For example, a letter from a Sudanese official to the PAICC, seen by Climate Home News, said that the country’s civil war had led to the suspension of its NDC preparation.

Who shapes climate science? The equity question facing the IPCC
Early completion of the next global climate science assessment reports risks excluding research from the Global South, which is key to ensuring the findings are fair
The US and Iran are not signed up to the Paris Agreement and so do not have active NDCs, nor does Taiwan, which is not a UN member state.
Rao said that because the PAICC is “facilitative and non-punitive”, naming the countries “is meant to open a door, not close one – the invited consultation is the point”.
“In recent months, governments that explained their constraints, whether capacity, finance or domestic process, have been met with follow-up and support rather than sanction, and the number of silent governments has fallen sharply,” Rao said.
