Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Record floods across the globe
IVORY COAST: Floods and landslides killed at least 24 people in Ivory Coast’s largest city of Abidjan after a week of heavy rains that was “four times the usual volume in some cases”, the Associated Press reported. The newswire added that the city’s disadvantaged communities are “particularly vulnerable” because of poor storm drainage in informal settlements.
CHINA ‘SWAMPED’: Landslides killed eight people in their homes in southern China’s Hunan province, said the South China Morning Post, with Taoyuan county receiving 39.5cm of rain in a day. Record rains “swamped” Hunan’s capital of Changsha, “turning roads into rivers and submerging subway tunnels”, Reuters wrote. By Monday, 33 rivers had “exceeded warning levels”, Xinhua reported. Associated Press also reported that flooding killed two people in the “deluged” US midwest.
BANGLADESH INUNDATED: Widespread flooding has stranded nearly two million people in north-east Bangladesh, CNN reported. It added that “large swathes” of Sylhet and Sunamganj provinces were underwater after a second wave of flooding hit the region in less than a month, with 772,000 children “in urgent need of assistance”. Camps in Cox’s Bazaar that accommodate “almost [one million] documented [Rohingya] refugees have been overrun by the incoming floodwaters”, Down to Earth reported, with at least 10 Rohingya fatalities out of the total 31 deaths in the Bangladesh floods this year.
Heat deaths: tolls apart
PAKISTAN’S FATAL HEAT: Doctors in Karachi “treated thousands of victims of heatstroke at various hospitals” after a “days-long heatwave” scorched southern Pakistan, the Associated Press reported. While local media reported that the heatwave “killed more than two dozen people” in Karachi alone, AP added that “no government spokesman was available to confirm the number of heatstroke-related deaths”. However, the Edhi ambulance service told BBC News it had taken around 568 people’s bodies to the Karachi city morgue in Pakistan over the past six days – up from its usual rate of 30-40 bodies a day.
‘TOLLS APART’: In neighbouring India, the country’s health ministry said 143 people across the country had died of heatstroke from the start of summer until 20 June, far lower than 209 confirmed and 448 suspected deaths tallied by Times of India. Meanwhile, a non-profit report estimated that “192 homeless individuals died from the heat in just nine days” in the national capital region alone, experts in India Development Review Online wrote, “highlighting the significant underreporting of heat-related deaths” in the country.
CULPABLE HEAT: In the US, the Boston Globe reported that New England experienced the “highest rate of heat-related emergency department visits” in the country, with temperatures in the region crossing 32C. Meanwhile, prosecutors in Arizona could “reasonably press homicide charges against big oil” for heat deaths in the state last year, the Guardian reported. Finally, Reuters wrote that the “sweltering summer” is worsening conditions in Gaza, where “nearly all the 2.3 million inhabitants have been driven from their homes by Israel’s military campaign” with almost no access to electricity and little clean water.
Around the world
- COW TAX: Denmark is set to introduce the world’s first carbon tax on agriculture after a historic agreement on Monday, Politico reported. Farmers will be charged “almost €100 a year” per cow once the levy rolls out in 2030, Financial Times said.
- PARLEY VOUS: In a “new and surprising” move, South China Morning Post reported that China agreed to talks with the EU over its plans to raise tariffs on electric vehicle imports by 48%.
- MAI KUHIHEWA: Youth in the US state of Hawaii who sued transport authorities for their use of fossil fuels reached a “first-of-its-kind” settlement that recognised their “constitutional rights to a life-sustaining climate”, Teen Vogue reported.
- OILSTRUCK: Financial Times reported on ExxonMobil’s development of “one of the largest offshore oil developments in history” and what it could mean for Guyana.
- BP U-TURN: Oil and gas giant BP has imposed a hiring freeze and paused new offshore wind projects to place a greater emphasis on oil and gas rather than renewables amid investor discontent, sources at the company told Reuters.
- PIPELINE PROTESTS: 37 activists in Uganda were arrested for protesting the East African Crude Oil Pipeline (EACOP), calling on China to “reject financial support” to the project, All Africa reported.
£116bn £30bn £2.8tn
Some of the “scary-sounding” numbers being used to mislead the public about the “cost” of net-zero in the UK general-election campaign. Carbon Brief’s Dr Simon Evans has factchecked them.
Latest climate research
- A new study in Nature Ecology and Evolution found that Earth’s most extreme wildfires increased 2.2-fold in the past 20 years, with the last seven years seeing the six most extreme fires on record.
- According to new research in Nature Climate Change, a 1C rise in average temperatures would mean four extra minutes every day spent collecting water for women. By 2050, women could spend 30% and 100% more time – globally and regionally – collecting water, “undermining” their welfare.
- New research on grounding zones – where ice transitions from land to water – suggests that sea-level rise projections could be substantially underestimated, according to a Carbon Brief guest post.

New Carbon Brief analysis found that UK governments in England, Scotland, Wales and Northern Ireland have missed their tree-planting targets set in 2020 and failed to plant an area of forest nearly the size of Birmingham. Tree-planting is a “significant” part of the UK’s net-zero strategy to compensate for other polluting sectors. By 2050, the unplanted trees would have removed some 8.5m tonnes of CO2 from the atmosphere, roughly 2% of the UK’s annual emissions in 2023. This shortfall will need to be made up for with stronger efforts elsewhere if the UK’s net-zero by 2050 target is to be met.

Monsoon mixtape
As the UK gears up for Glastonbury, Carbon Brief interviews pioneering Indian hip-hop and folk artists about protest music and the role of artists in an era of climate change.
When Carbon Brief spoke to the Marathi-language rapper MC Mawali from the hip-hop collective Swadesi, Mumbai was under an orange alert for extremely heavy rains, after stalling for most of the month.
The monsoon has changed along with the mega-city most defined by it. Massive infrastructure projects have cost the island city its flood buffers, including the much-diminished Aarey forest, home to the Indigenous Warli tribe and the only urban leopard population in the world.
In 2019, Mawali, along with fellow Swadesi rappers and Warli bard Prakash Bhoir, gave Mumbai’s #SaveAarey movement its protest anthem, The Warli Revolt – its chorus warning of a dystopian climate future to come.
“I used to go to Aarey to swim in the Vihar lake as a kid, but I didn’t know about [Warli] culture, their instruments, their songs going extinct that are not on the internet,” said Mawali.
When the chainsaws came for the forest, Mawali says he “felt helpless”, but he’s happy to hear that Warli Revolt has become a go-to anti-deforestation anthem across the country since. He added:
“Today’s music business is about labels pouring in music and splashing their artists all over platforms that censor messages like ours, but, through hip-hop, we’ve learned to hijack that same system to keep folk, tribal and conscious music alive.”
To anti-caste singer-poet Dhammarakshit Randive from the Yalgaar Sanskrutik Manch collective, the word “green” has turned into “its own kind of propaganda” that justifies “ask-no-questions development”, with high displacement of people and a large emissions footprint.
“‘Green’ often becomes propaganda, telling us you can offset 100 trees in a biodiverse forest that Adivasis (Indigenous peoples) depend on by planting another 1,000 somewhere else,” he told Carbon Brief.
Randive sees climate change, anti-caste and “movements to centre democracy” as interlinked, “affecting all our lives, everywhere”. To him, the main role of musicians and artists in responding to climate change is to establish that intersectionality. He told Carbon Brief:
“Otherwise, those fighting for forests are dying unheard in those same forests, sanitation workers are dying in the same sewers, factory workers are dying in the heat and there’s no one to widen peoples’ perspectives to say ‘this is all part of the same struggle’.”
Taru Dalmia, also known as Delhi Sultanate, was among the earliest pioneers to fuse dub and dancehall with protest anthems penned by Indigenous singers, such as Bhagaban Majhi, protesting mining projects in central India. Blood Earth, the album Dalmia made with producer Chris McGuiness, is now 12-years-old, but remains just as relevant.
“At that time we made it, I felt that there was a kind of hidden violence and not as much discourse about a war-like situation in [mineral-rich Indian states],” said Dalmia, speaking to Carbon Brief. He feels that, since then, “there’s definitely more awareness and politicisation which has to do with how much more repressive things have gotten and [environmental and other] issues staring at us in the face”.
While hip-hop has “blown up” over the past half-decade, he feels that little has changed as far as mining companies are concerned, since “profit margins remain huge”. Dalmia added:
“This awareness of how fundamentally our way of life is based on extraction, extractive industries and destruction and how that’s a direct continuation of the colonial project…sure, there’s more politicisation, but the depth of it is still missing.”
While extreme weather has not quite made its way to the airwaves, aside from boilerplate Bollywood songs invoking heat and rain, mercury levels were the subject of one of India’s earliest environmental campaign songs.

In 2015, a young Sofia Ashraf dropped the single Kodaikanal Won’t, a rap parody of Nicki Minaj’s Anaconda, demanding that Unilever clean up toxic waste from its thermometer factory dumped in the rainforest and compensate its workers for mercury poisoning. It drew over 2m views, praise from Minaj and a public apology and settlement from Unilever. Speaking to Carbon Brief, Ashraf said:
“Since Kodaikanal Won’t, there has been a whole gamut of songs around climate change, from general awareness-building to pointed information-sharing, music has been used effectively to express the dread a lot of us live under. The downside is that greenwashing is constantly on the rise and there is too much onus on the audience to parse this content for the truth.”
But she remains optimistic, telling Carbon Brief:
“As long as art still strives to build conscious narratives, I feel we are headed in the right direction.”

PETROCENTRIC: Adam Hanieh, author and professor of political economy at the University of Exeter, spoke to the Break Down about all the ways in which oil came to “permeate” our lives.
MIC TEST: Vox tuned in to how scientists are listening to Puerto Rico’s frogs to understand how climate change is altering life on the rainforest island.
NON-ALIGNED: A piece in Drilled unpacked new research prompting questions of what “Paris-aligned” means and whether “climate pledges…need a terminology overhaul”.

Colombia proposes expert group to advance talks on minerals agreement
Colombia wants countries to discuss options for a global agreement to ensure that the extraction, processing and recycling of minerals – including those needed for the clean energy transition – don’t harm the environment and human wellbeing.
The mineral-rich nation is proposing to create an expert group to “identify options for international instruments, including global and legally-binding instruments, for coordinated global action on the environmentally sound management of minerals and metals through [their] full lifecyle”.
Colombia hopes this will eventually lead to an agreement on the need for an international treaty to define mandatory rules and standards that would make mineral value chains more transparent and accountable.
The proposal was set out in a draft resolution submitted to the UN Environment Assembly (UNEA) earlier this week and seen by Climate Home News. UNEA, which is constituted of all UN member states, is the world’s top decision-making body for matters relating to the environment. The assembly’s seventh session will meet in Kenya in December to vote on countries’ proposals.
Soaring demand for the minerals used to manufacture clean energy technologies and electric vehicles, as well as in the digital, construction and defence industries have led to growing environmental destruction, human rights violations and social conflict.
Colombia argues there is an “urgent need” to strengthen global cooperation and governance to reduce the risks to people and the planet.
Options for a global minerals agreement
The proposal is among a flurry of initiatives to strength global mineral governance at a time when booming demand is putting pressure on new mining projects.
Colombia, which produces emeralds, gold, platinum and silver for exports, first proposed the idea for a binding international agreement on minerals traceability and accountability on the sidelines of the UN biodiversity talks it hosted in October 2024.
Since then, the South American nation has been quietly trying to drum up support for the idea, especially among African and European nations.
Its draft resolution to UNEA7 contains very few details, leaving it open for countries to discuss what kind of global instrument would be best suited to make mineral supply chains more transparent and sustainable.
Does the world need a global treaty on energy transition minerals?
Colombia says it wants the expert group to build on other UN initiatives, including a UN Panel on Critical Energy Transition Minerals, which set out seven principles to ensure the mining, processing and recycling of energy transition minerals are done responsibly and benefit everyone.
The group would include technical experts and representatives from international and regional conventions, major country groupings as well as relevant stakeholders.
It would examine the feasibility and effectiveness of different options for a global agreement, consider their costs and identify measures to support countries to implement what is agreed.
The resolution also calls for one or two meetings for member states to discuss the idea before the UNEA8 session planned in late 2027, when countries would decide on a way forward.
No time to lose for treaty negotiations
Colombia’s efforts to advance global talks on mineral supply chains have been welcomed by resource experts and campaigners. But not everyone agrees on the best strategy to move the discussion forward at a time when multilateralism is coming under attack.
Johanna Sydow, a resource policy expert who heads the international environmental policy division of the Heinrich-Böll Foundation, said she had hoped that the resolution would explicitly call for negotiations to begin on an international minerals treaty.
“Treaty negotiations take a long time. If you don’t even start with it now, it will take even longer. I don’t see how in two or three years it will be easier to come to an agreement,” she told Climate Home.
Despite the geopolitical challenges, “we need joint rules to prevent a huge race to the bottom for [mineral] standards”. That could start with a group of countries coming together and starting to enforce joint standards for mining, processing and recycling minerals, she said.
But any meaningful global agreement on mineral supply chains would require backing from China, the world’s largest processor of minerals, which dominates most of the supply chains. And with Colombia heading for an election in May, it will need all the support it can get to move its proposal forward.
‘Voluntary initiative won’t cut it’
Juliana Peña Niño, Colombia country manager at the Natural Resource Governance Institute, is more optimistic. “Colombia’s leadership towards fairer mineral value chains is a welcome step,” she told Climate Home News.
“At UNEA7, we need an ambitious debate that gives the proposed expert group a clear mandate to advance concrete next steps — not delay decisions — and that puts the voices of those most affected at the centre. One thing is clear: the path forward must ultimately deliver a binding instrument, as yet another voluntary initiative simply won’t cut it,” she said.
More than 50 civil society groups spanning Latin America, Africa and Europe previously described Colombia’s work on the issue as “a chance to build a new global paradigm rooted in environmental integrity, human rights, Indigenous Peoples’ rights, justice and equity”.
“As the energy transition and digitalisation drive demand for minerals, we cannot afford to repeat old extractive models built on asymmetry – we must redefine them,” they wrote in a statement.

DeBriefed 3 October 2025: UK political gap on climate widens; Fossil-fuelled Typhoon Ragasa; ‘Overshoot’ unknowns
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Shattered climate consensus
FRACKING BAN: UK energy secretary Ed Miliband has announced that the government will bring forward its plans to permanently ban fracking, in a move designed to counter a promise from the hard-right Reform party to restart efforts to introduce the practice, the Guardian said. In the same speech, Miliband said Reform’s plans to scrap clean-energy projects would “betray” young people and future generations, the Press Association reported.
ACT AXE?: Meanwhile, Kemi Badenoch, leader of the Conservatives, pledged to scrap the 2008 Climate Change Act if elected, Bloomberg reported. It noted that the legislation was passed with cross-party support and strengthened by the Conservatives.
‘INSANE’: Badenoch faced a backlash from senior Tory figures, including ex-prime minister Theresa May, who called her pledge a “catastrophic mistake”, said the Financial Times. The newspaper added that the Conservatives were “trailing third in opinion polls”. A wide range of climate scientists also condemned the idea, describing it as “insane”, an “insult” and a “serious regression”.
Around the world
- CLIMATE CRACKDOWN: The US Department of Energy has told employees in the Office of Energy Efficiency and Renewable Energy to avoid using the term “climate change”, according to the Guardian.
- FOREST DELAY: Plans for Brazil’s COP30 flagship initiative, the tropical forests forever fund, are “suffer[ing] delays” as officials remain split on key details, Bloomberg said.
- COP MAY BE ‘SPLIT’: Australia could “split” the hosting of the COP31 climate summit in 2026 under a potential compromise with Turkey, reported the Guardian.
- DIVINE INTERVENTION: Pope Leo XIV has criticised those who minimise the “increasingly evident” impact of global warming in his first major climate speech, BBC News reported.

Clean energy has met 100% of Great Britain’s electricity demand for a record 87 hours this year so far, according to new Carbon Brief analysis. This is up from just 2.5 hours in 2021 and 64.5 hours in all of 2024. The longest stretch of time where 100% of electricity demand was met by clean energy stands at 15 hours, from midnight on 25 May 2025 through to 3pm on 26 May, according to the analysis.

‘Overshoot’ unknowns
As the chances of limiting global warming to 1.5C dwindle, there is increasing focus on the prospects for “overshooting” the Paris Agreement target and then bringing temperatures back down by removing CO2 from the atmosphere.
At the first-ever Overshoot Conference in Laxenburg, Austria, Carbon Brief asks experts about the key unknowns around warming “overshoot”.
Sir Prof Jim Skea
Chair of the Intergovernmental Panel on Climate Change (IPCC) and emeritus professor at Imperial College London’s Centre for Environmental Policy
So there are huge knowledge gaps around overshoot and carbon dioxide removal (CDR). As it’s very clear from the themes of this conference, we don’t altogether understand how the Earth would react in taking CO2 out of the atmosphere.
We don’t understand the nature of the irreversibilities and we don’t understand the effectiveness of CDR techniques, which might themselves be influenced by the level of global warming, plus all the equity and sustainability issues surrounding using CDR techniques.
Prof Kristie Ebi
Professor at the University of Washington’s Center for Health and the Global Environment
There are all kinds of questions about adaptation and how to approach effective adaptation. At the moment, adaptation is primarily assuming a continual increase in global mean surface temperature. If there is going to be a peak – and of course, we don’t know what that peak is – then how do you start planning? Do you change your planning?
There are places, for instance when thinking about hard infrastructure, [where overshoot] may result in a change in your plan – because as you come down the backside, maybe the need would be less. For example, when building a bridge taller. And when implementing early warning systems, how do you take into account that there will be a peak and ultimately a decline? There is almost no work in that. I would say that’s one of the critical unknowns.
Dr James Fletcher
Former minister for public service, sustainable development, energy, science and technology for Saint Lucia and negotiator at COP21 in Paris.
The key unknown is where we’re going to land. At what point will we peak [temperatures] before we start going down and how long will we stay in that overshoot period? That is a scary thing. Yes, there will be overshoot, but at what point will that overshoot peak? Are we peaking at 1.6C, 1.7C, 2.1C?
All of these are scary scenarios for small island developing states – anything above 1.5C is scary. Every fraction of a degree matters to us. Where we peak is very important and how long we stay in this overshoot period is equally important. That’s when you start getting into very serious, irreversible impacts and tipping points.
Prof Oliver Geden
Senior fellow and head of the climate policy and politics research cluster at the German Institute for International and Security Affairs and vice-chair of IPCC Working Group III
[A key unknown] is whether countries are really willing to commit to net-negative trajectories. We are assuming, in science, global pathways going net-negative, with hardly any country saying they want to go there. So maybe it is just an academic thought experiment. So we don’t know yet if [overshoot] is even relevant. It is relevant in the sense that if we do, [the] 1.5C [target] stays on the table. But I think the next phase needs to be that countries – or the UNFCCC as a whole – needs to decide what they want to do.
Prof Lavanya Rajamani
Professor of international environmental law at the University of Oxford
I think there are several scientific unknowns, but I would like to focus on the governance unknowns with respect to overshoot. To me, a key governance unknown is the extent to which our current legal and regulatory architecture – across levels of governance, so domestic, regional and international – will actually be responsive to the needs of an overshoot world and the consequences of actually not having regulatory and governance architectures in place to address overshoot.
