Welcome to Carbon Brief’s DeBriefed. 
An essential guide to the week’s key developments relating to climate change.

This week

Deadly floods in Asia

MOUNTING DEVASTATION: The Associated Press reported that the death toll from catastrophic floods in south-east Asia had reached 1,500, with Indonesia, Sri Lanka and Thailand most affected and hundreds still missing. The newswire said “thousands” more face “severe” food and clean-water shortages. Heavy rains and thunderstorms are expected this weekend, it added, with “saturated soil and swollen rivers leaving communities on edge”. Earlier in the week, Bloomberg said the floods had caused “at least $20bn in losses”.

CLIMATE CHANGE LINKS: A number of outlets have investigated the links between the floods and human-caused climate change. Agence France-Presse explained that climate change was “producing more intense rain events because a warmer atmosphere holds more moisture and warmer oceans can turbocharge storms”. Meanwhile, environmental groups told the Associated Press the situation had been exacerbated by “decades of deforestation”, which had “stripped away natural defenses that once absorbed rainfall and stabilised soil”. 

‘NEW NORMAL’: The Associated Press quoted Malaysian researcher Dr Jemilah Mahmood saying: “South-east Asia should brace for a likely continuation and potential worsening of extreme weather in 2026 and for many years.” Al Jazeera reported that the International Federation of Red Cross and Red Crescent Societies had called for “stronger legal and policy frameworks to protect people in disasters”. The organisation’s Asia-Pacific director said the floods were a “stark reminder that climate-driven disasters are becoming the new normal”, the outlet said.

Around the world

• REVOKED: The UK and Netherlands withdrew $2.2bn of financial backing from a controversial liquified natural gas (LNG) project in Mozambique, Reuters reported. The Guardian noted that TotalEnergies’ “giant” project stood accused of “fuelling the climate crisis and deadly terror attacks”.
• REVERSED: US president Donald Trump announced plans to “significantly weaken” Biden-era fuel efficiency requirements for cars, the New York Times said.
• RESTRICTED: EU leaders agreed to ban the import of Russian gas from autumn 2027, the Financial Times reported. Meanwhile, Reuters said it is “likely” the European Commission will delay announcing a plan on auto sector climate targets next week, following pressure to “weaken” a 2035 cut-off for combustion engines. 
• RETRACTED: An influential Nature study that looked at the economic consequences of climate change has been withdrawn after “criticism from peers”, according to Bloomberg. [The research came second in Carbon Brief’s ranking of the climate papers most covered by the media in 2024.]
• REBUKED: The federal government of Canada faced a backlash over an oil pipeline deal struck last week with the province of Alberta. CBC News noted that ​​First Nations chiefs voted “unanimously” to demand the withdrawal of the deal and Canada’s National Observer quoted author Naomi Klein as saying that the prime minister was “completely trashing Canada’s climate commitments”.
• RESCHEDULED: The Indonesian government has cancelled plans to close a coal plant seven years early, Bloomberg reported. Meanwhile, Bloomberg separately reported that India is mulling an “unprecedented increase” in coal-power capacity that could see plants built “until at least 2047”.

Captured

A new target for developed nations to triple adaptation finance by 2035, agreed at the COP30 climate summit, would not cover more than a third of developing countries’ estimated needs, Carbon Brief analysis showed. The chart above compares a straight line to meeting the adaptation finance target (blue), alongside an estimate of countries’ adaptation needs (grey), which was calculated using figures from the latest UN Environmental Programme adaptation gap report, based on countries’ UN climate plans (called “nationally determined contributions” or NDCs) and national adaptation plans (NAPs).

Spotlight

Inclusivity at the IPCC

This week, Carbon Brief speaks to an IPCC lead author researching ways to improve the experience of global south scientists taking part in producing the UN climate body’s assessments.

Hundreds of climate scientists from around the world met in Paris this week to start work on the Intergovernmental Panel on Climate Change’s (IPCC’s) newest set of climate reports.

The IPCC is the UN body responsible for producing the world’s most authoritative climate science reports. Hundreds of scientists from across the globe contribute to each “assessment cycle”, which sees researchers aim to condense all published climate science over several years into three “working group” reports.

The reports inform the decisions of governments – including at UN climate talks – as well as the public understanding of climate change. 

The experts gathering in Paris are the most diverse group ever convened by the IPCC. 

Earlier this year, Carbon Brief analysis found that – for the first time in an IPCC cycle – citizens of the global south make up 50% of authors of the three working group reports. The IPCC has celebrated this milestone, with IPCC chair Prof Jim Skea touting the seventh assessment report’s (AR7’s) “increased diversity” in August. 

But some IPCC scientists have cautioned that the growing involvement of global south scientists does not translate into an inclusive process.

“What happens behind closed doors in these meeting rooms doesn’t necessarily mirror what the diversity numbers say,” Dr Shobha Maharaj, a Trinidadian climate scientist who is a coordinating lead author for working group two (WG2) of AR7, told Carbon Brief.

Global south perspective

Motivated by conversations with colleagues and her own “uncomfortable” experience working on the small-islands chapter of the sixth assessment cycle (AR6) WG2 report, Maharaj – an adjunct professor at the University of Fiji – reached out to dozens of fellow contributors to understand their experience. 

The exercise, she said, revealed a “dominance of thinking and opinions from global north scientists, whereas the global south scientists – the scientists who were people of colour – were generally suppressed”. 

The perspectives of scientists who took part in the survey and future recommendations for the IPCC are set out in a peer-reviewed essay – co-authored by 20 researchers – slated for publication in the journal PLOS Climate. (Maharaj also presented the findings to the IPCC in September.)

The draft version of the essay notes that global south scientists working on WG2 in AR6 said they confronted a number of diversity, equity and inclusion (DEI) issues, including “skewed” author selection, “unequal” power dynamics and a “lack of respect and trust”. The researchers also pointed to logistical constraints faced by global south authors, such as visa issues and limited access to journals.

The anonymous quotations from more than 30 scientists included in the essay, Maharaj said, are “clear data points” that she believes can advance a discussion about how to make academia more inclusive.

“The literature is full of the problems that people of colour or global south authors have in academia, but what you don’t find very often is quotations – especially from climate scientists,” she said. “We tend to be quite a conservative bunch.”  

Road to ‘improvement’

Among the recommendations set out in the essay are for DEI training, the appointment of a “diversity and inclusion ombudsman” and for updated codes of conduct.

Marharaj said that these “tactical measures” need to occur alongside “transformative approaches” that help “address value systems, dismantle power structures [and] change the rules of participation”. 

With drafting of the AR7 reports now underway, Maharaj said she is “hopeful” the new cycle can be an improvement on the last, pointing to a number of “welcome” steps from the IPCC.

This includes holding the first-ever expert meeting on DEI this autumn, new mechanisms where authors can flag concerns and the recruitment of a “science and capacity officer” to support WG2 authors. 

The hope, Maharaj explained, is to enhance – not undermine – climate science.

“The idea here was to move forward and to improve the IPCC, rather than attack it,” she said. “Because we all love the science – and we really value what the IPCC brings to the world.”

BROKEN PROMISES: Climate Home News spoke to communities in Nigeria let down by the government’s failure to clean up oil spills by foreign companies.

‘WHEN A ROAD GOES WRONG’: Inside Climate News looked at how a new road from Brazil’s western Amazon to Peru has become a “conduit for rampant deforestation and illegal gold mining”.

SHADOWY COURTS: In the Guardian, George Monbiot lamented the rise of investor-state dispute settlements, which he described as “undemocratic offshore tribunals” that are already having a “chilling effect” on countries’ climate ambitions.
