Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Energy outlook
DEMAND SURGING: The International Energy Agency (IEA) published its annual World Energy Outlook report – a “comprehensive” summary of global energy trends – the New York Times reported. The outlet said, over the next decade, the world will add the equivalent of Japan’s annual electricity demand each year, driven by demand for new factories, electric vehicles, air-conditioners and data centres. (Axios said the IEA included a “reality check” about data centre demand, which would only make up a “small share” of growth by 2030.)
AGE OF ELECTRICITY: Reuters reported that the “world is on the brink of a new age of electricity”, with global fossil fuel demand set to peak by the end of the decade. The newswire added that “surplus oil and gas supplies could drive investment into green energy”. The Wall Street Journal said clean energy would grow faster than global energy demand, becoming the largest source of power in the mid-2030s, according to the IEA. Carbon Brief has just published an in-depth analysis of the report’s findings. (See Captured below.)
COP16 kickoff
BIODIVERSITY TALKS: The COP16 biodiversity summit begins in Cali, Colombia, on Monday. It will be the first set of UN biodiversity negotiations since the world’s nations agreed a landmark deal in 2022 to “halt and reverse” nature loss by the end of the decade.
MISSED PLEDGES: Joint analysis published on Tuesday by Carbon Brief and the Guardian showed that more than 85% of countries are set to miss the UN’s deadline to submit new nature pledges, known as national biodiversity strategies and action plans (NBSAPs).
WHAT TO WATCH: Carbon Brief’s team of journalists on the ground in Cali will host a webinar on Tuesday at 3pm UK time to discuss the key issues facing negotiators and answering questions. (Sign up for free.) Through the fortnight of the talks, they will also be scrutinising each new draft negotiating text as it lands, explaining areas of disagreement and updating Carbon Brief’s interactive text tracker.
After the storm
DEVASTATING DAMAGES: Hurricanes Helene and Milton are “likely” to each rack up costs of more than $50bn, the Associated Press reported. According to the newswire, “government and private experts” say the hurricanes could join the “infamous ranks” of Katrina, Sandy and Harvey – which are among the eight US storms to have ever caused damages of more than $50bn.
PAYOUTS: The US Small Business Administration has exhausted funds for its disaster loan program following increased demand from Hurricane Helene, Reuters warned. Officials said the program needs about $1.6bn amid heightened demand following Hurricane Helene, according to the Hill. The Financial Times estimated that Milton alone will lead to about $36bn of insurance payouts for the private sector.
Around the world
- DIRTY ENERGY: Burning household rubbish to make electricity is now the “dirtiest way the UK generates power”, BBC News reported.
- COP BID: Australia has launched a bid to host the COP31 climate summit in 2026 in Adelaide, according to the Guardian.
- FINANCE FAIL: The EU unveiled its negotiating stance for the COP29 climate talks next month, but did not address how it will boost funding for developing countries, according to Bloomberg.
- CURBING COAL: The US Supreme Court allowed the Environmental Protection Agency to move ahead with its plans to limit carbon emissions by power plants, despite a pending challenge from 27 mainly-Republican states, the New York Times reported.
- WARNING MESSAGE: Activist group Friends of the Earth warned the UK government to drop its support for a Mozambique gas project “embroiled in allegations of abduction, murder and rape”, said Politico.
- WIND POWER: A Chinese company developed the world’s “most powerful” floating offshore wind turbine with a capacity of 20 megawatts, state news agency Xinhua said.
60%
Global increase in forest fire carbon emissions over 2001-23, according to a new paper in Science.
Latest climate research
- Recent floods that killed at least 244 people in Nepal were driven by rainfall made “about 10% more intense” by human-caused climate change, according to a rapid attribution study.
- Drought and aridity are already having a “significant impact” on internal migration – especially in arid and “hyper-arid” regions of southern Europe, South Asia, Africa and the Middle East and South America – new research found.
- Many people in the US are experiencing “psychological distress” from climate change, but those who do are more involved in collective climate action, a new study said.

Captured
Electricity generation from solar is set to quadruple by 2030, sending coal power tumbling and becoming the world’s largest source of electricity by 2033, according to Carbon Brief analysis of the International Energy Agency’s World Energy Outlook. The report finds that global CO2 emissions are set to peak “imminently”, as the “age of electricity” sends fossil fuels into decline. See Carbon Brief’s in-depth coverage of the report.
Spotlight
Is global warming ‘accelerating’?
A recent “surge” in global warming is not statistically “detectable”, according to a study published this week. But does this mean it is not happening? Carbon Brief speaks to the lead author of the study and explores the debate on a warming acceleration.
Global temperatures are soaring. Last year was the hottest year on record, with global surface temperatures reaching 1.34-1.54C above pre-industrial levels. But 2024 is already setting blistering new records and is expected to knock 2023 off the top spot.
Against this backdrop of ever-worsening heat, a new study in Communications Earth and Environment used statistical methods to see whether an acceleration in global warming could be formally detected.
The authors find a “changepoint” in the rate of warming around the year 1970, but find no “statistically detectable” acceleration since then.
Dr Claudie Beaulieu is the paper’s lead author and an associate professor in the Ocean Sciences Department at UC Santa Cruz. She told Carbon Brief: “If an acceleration in global warming is occurring, the size of that acceleration is either too small or too recent to robustly detect it in globally-averaged surface temperature records.”
However, some scientists questioned the methods used in the study. Prof Richard Allan, a professor of climate science at the University of Reading, said the surface warming data used in this study is “influenced by natural variation”. He argued that “when all lines of evidence are scrutinised” – such as satellite data and ocean measurements – “it is apparent that climate change is accelerating rather than continuing steadily”.
Carbon Brief’s climate science contributor, Dr Zeke Hausfather, published a factcheck earlier this year on the acceleration in global warming. Assessing observations and climate model output, he concluded that “that there is increasing evidence of an acceleration in the rate of warming over the past 15 years”.
Beaulieu told Carbon Brief that present-day discussion about an acceleration in warming is similar to the debate over a warming “hiatus” about a decade ago. She continued:
“Back then, also using statistical methods, we showed that a ‘hiatus’ in warming was not detectable. With hindsight of more years of observations it is now obvious warming had just continued leading to the record heat of 2023. We need to keep monitoring.”
Dr John Kennedy is the co-chair of the World Meteorological Organisation (WMO) expert team on climate monitoring and assessment and scientific coordinator for the annual WMO State of the Global Climate reports.
He warned that this statistical method can mean waiting many years for warming – or a lack of warming – to be detectable. In a blog post earlier this year, Kennedy wrote:
“One thing that became clear during the ‘hiatus’ is that this kind of analysis is the kind of thing you do when you’re set (for whatever reason) on being the last person to know there is a hiatus.”
He added: “There are good physical reasons to expect an increase in the underlying warming.”
Beaulieu does not refute that warming might be accelerating. She said that “the point of the paper is that it will take additional years of observations to detect a sustained acceleration”.

SYDNEY, Thursday 30 October 2026 — In response to reports that the Albanese government is set to introduce draft legislation this year that would seek to ban data centres in Australia’s suburbs, Joe Rafalowicz, Head of Climate and Energy at Greenpeace Australia Pacific, said:
“These reports are a testament to the growing community opposition to these completely inappropriate AI factories that have sprung up across our suburbs, and Big Tech corporations should take heed — the data centre build-out must not happen without the endorsement of the Australian people.
“But the government can’t simply ship this problem out to regional Australia without addressing the fundamental issues with this extractive new industry.
“We’re already seeing a trend of AI data centre proposals moving to the regions, in areas that are more water-scarce, more environmentally sensitive, and next to sources of fracked and coal seam gas to support their massive BYO gas-fired power plans — a pattern we’ve seen play out in the United States.
“From the Beetaloo Basin in the NT to the Western Downs in Qld, we’re seeing a wave of AI data centre proposals that would see new gas fast-tracked to support their massive energy demand, and threaten to completely derail Australia’s energy transition.
“Just as suburban Australians are asking, “what for?”, regional communities like Berry Springs and Dalby do not want dirty data centres setting up shop with absolutely no benefit to their communities. Greenpeace is calling for a moratorium on AI data centre developments until strict and enforceable safeguards are in place to protect our climate and our communities.”

AI data centre ban in suburbs would not address fundamental issues: Greenpeace
In the thick of the COP29 climate summit in Azerbaijan in 2024, the UN climate talks were rattled by what can only be described as a major PR disaster. The BBC, Reuters and The Guardian all carried headlines, attributed to leading climate policy experts, that the COPs were “no longer fit for purpose”.
The articles outlined a series of reforms called for in an open letter signed by 22 eminent scientists and politicians, including a former UN secretary-general and previous UN climate chief, with a further 150 lending their support. The headlines shook confidence in the COP process, just as governments were wrestling over a new climate finance goal.
The Club of Rome – which handled the media relations for the letter – hurried to say that its “constructive, supportive ideas” had been “misinterpreted”. Negotiators kept calm(ish) and carried on, in the end landing the finance goal after some high-stakes drama on the final day.

Early speakers’ list suggests few powerful leaders will attend COP31
Just 77 heads of state or government are scheduled to address the COP31 climate summit in Antalya, a third less than the COP28 peak -
Africa wants adaptation finance on COP31 agenda, raising risk of a fight
The African Group wants dedicated space on tripling adaptation finance, the Green Climate Fund and trade, setting up a possible clash
To my surprise, when I went back this week to read the letter again, I could not find the offending line about the COPs not being fit for purpose. The Club of Rome has yet to respond to my query about its disappearance.
Whatever happened to the wording, that sentiment has been widely shared. COPs have ballooned in size while the importance of their outcomes seems to have diminished since the 2015 Paris Agreement (with the exception of the 2023 COP in Dubai where countries agreed to transition away from fossil fuels in energy systems).
The same on the surface
Two years on from those painful headlines in Baku, has anything changed for the better? You might be forgiven for thinking not. Official decisions are still made by consensus rather than the majority voting some have called for to stop blockers.
Tens of thousands of officials, activists and business execs still scurry around the halls to an ever-growing list of side events, roundtables and dialogues, while deals still come down to rows, all-nighters and jargon-filled texts adopted to rounds of applause.
But it would not be true to say that COPs have completely failed to respond to the very real need to translate the words of the Paris Agreement into action in the outside world.
Global warming is projected to be around 1.3C lower this century than it would have been if the world had not committed to tackle the climate crisis under that accord. Developing countries have a valued space at COPs in which their voices have equal weight in decision-making, unlike in many other international fora. And most importantly, perhaps, there has been a subtle shift, tipping the balance away from negotiating towards doing.
Brazil branded last year’s summit in Belém as the “COP of Implementation”, corralling the sprawling Action Agenda into six axes. This was a bid to impose some structure on the mushrooming efforts between governments, UN agencies, cities, businesses and civil society to set targets and spur faster results on their pet issues, from methane emissions to health and adaptation in conflict zones. COP30 alone saw the launch of 120 “plans to accelerate solutions”.
COP30 roadmaps off the cuff
Meanwhile, as the formal negotiations drew to a close, it was clear that consensus decision-making was evolving into something a little more improvised.
With only around half of all countries on board with the idea of a roadmap to transition away from fossil fuels, COP30 President André Corrêa do Lago announced his team would put one together over the coming year, along with another on how to meet a global goal to halt deforestation by 2030. Those roadmaps will be launched next week, presented and discussed at COP31, though it’s still unclear whether or how they’ll be incorporated into the formal negotiating agenda.
Some leading policy-makers don’t think that matters too much. Speaking to journalists before the Antalya summit, COP30 CEO Ana Toni and Dutch climate minister Stientje van Veldhoven said “coalitions of the willing” can move ahead without needing consensus from the COPs. This, they said, was evident this year at the first global conference on TAFF, co-chaired by van Veldhoven and attended by 60 countries.
“Consensus or no-consensus in the general COP doesn’t make a difference for the choices I have to make in my country to get my country to phase out fossil fuels,” said the Dutch minister. The Netherlands recently became one of the first to publish a national TAFF plan.
COP31 banks on flagship voluntary initiatives
This thinking has permeated the management and expected outcomes of this year’s COP too. Earlier this year, Türkiye, supported by international energy agencies, floated the idea of a voluntary goal to boost electrification to 35% of the world’s final energy consumption by 2035 – and this is now being touted as one of the main results to be expected from Antalya.
Türkiye is also championing a pledge on AI and climate, while co-host Australia is pushing to ease access to climate finance for least developed countries and small island states.
COP31 presidency announces AI pledge as UN climate chief says Big Tech ‘on thin ice’
None of these needs consensus. But with a political cover decision already in the works, as trailed by the COP presidents, they – and perhaps the fossil fuel roadmap – may find a home in the official text if language acceptable to most can be found, giving them them additional weight.
UNFCCC reform process in the shadows
Formal reform is underway too, if quietly. UN climate chief Simon Stiell is leading a review informed by ongoing consultations with a group of 15 well-respected climate policy experts, three of whom signed the open letter in 2024.
Among them is leading Swedish climate and sustainability scientist Johan Rockström who has strong ideas about how to make COPs function better, including a switch to majority voting. He told the same press briefing nothing stands in the way of this, because the rules of procedure for making decisions at COPs have never been formally agreed.
Still, to get away from the default setting of consensus would require agreement on a new system that may be impossible to achieve given the rise in bullying tactics by fossil fuel heavyweights.
Comment: The UN climate process was built for negotiation – now it must support implementation
The deliberations with the high-level policy gurus, as reflected in a summary of June’s session in Bonn, largely echo what’s already happening organically, calling for stronger partnerships and accountability both in and between the Action Agenda and negotiations. It doesn’t mention voting.
A general overview of the reform exercise says that “improving and optimizing the [UN climate] process over the medium to long term… will be critical to fostering trust, enhancing collaboration, and catalyzing increased ambition”.
In the short term, don’t hold your breath for anything concrete on reform at COP31 but watch for signs in what ends up dominating the headlines from Türkiye.
