Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Raging wildfires
SOUTH KOREAN BLAZE: Wildfires in south-eastern South Korea – the “worst wildfires in its history” – have killed at least 27 people and displaced more than 37,000 from their homes, the Korea Times reported. The Chosun Daily said that the 1,300-year-old Gounsa Temple “was reduced to ashes” and the fire continues to endanger many of the “most prized cultural assets”. A “spate” of recent wildfires in South Korea and Japan have been “linked to climate change”, the Japan Times said.
FUEL TO THE FIRES: Parts of North and South Carolina have been under evacuation orders due to several large, uncontained wildfires, with “millions of downed trees” from September’s Hurricane Helene fuelling the blazes, the Raleigh News & Observer reported. The Guardian added: “Many people in the area are still getting over the hurricane.”
UK climate and energy roundup
DEADLINE DROPPED: The UK’s High Court “agreed to push back the deadline” for the government to modify its “delivery plan” needed to meet its legally binding climate targets, BusinessGreen reported. The plan was published in 2023, but had been “subject to a legal challenge from green groups, which alleged it was not sufficiently detailed”, the outlet added.
‘GREEN SILENCE’: UK chancellor Rachel Reeves made “no mention of green issues” in her spring statement, the Guardian reported, adding that this “silence [came] as a relief” to “green experts”, given cuts announced elsewhere. Meanwhile, the Chinese owner of British Steel “rejected a £500m lifeline offer from the UK government, raising fears about thousands of jobs at the steelmaker”, the Financial Times reported.
Around the world
- IT’S ELECTRIC: Chinese automaker BYD “topped $100bn” in sales of electric vehicles and plug-in hybrids, surpassing electric-only manufacturer Tesla, the Financial Times said. Tesla sales have fallen 49% year-on-year in Europe in 2025, ABC News noted, even as EV sales overall grew 28%.
- CARBON MARKET: China released plans to include its steel, cement and aluminium industries in the country’s carbon-trading market, Reuters reported.
- COAL COMMITMENT: Germany’s incoming coalition “stand[s] by” plans to phase out coal power by 2038, according to a leaked draft reported by Euractiv, which noted the outgoing government had “favoured” 2030.
- POWER SURGE: Record temperatures in 2024 meant “global energy demand surged” last year, according to a report from the International Energy Agency covered by the Wall Street Journal. A record 585 gigawatts of new renewables were added last year, Axios reported, citing International Renewable Energy Agency data.
- SHIP-SHAPE: In Climate Home News, Kenya’s special envoy for climate change, Ambassador Ali Mohamed, “unequivocally” endorsed a proposed carbon levy on emissions from ships.
267
The number of days in 2024 – nearly three-quarters of the year – in which the US was experiencing a “major disaster”, according to analysis of US Federal Emergency Management Agency data by the International Institute for Environment and Development and CNN.
Latest climate research
- Research in the Journal of Environmental Psychology found that political polarisation around climate change becomes more pronounced as countries become wealthier.
- In China, compound hot-dry and hot-wet events became more frequent, long-lasting and intense from 1985 to 2019, with serious implications for crop losses, a new study in Earth’s Future found.
- A study in Environmental Research Letters detailed a machine learning-driven model capable of accurately forecasting marine heatwaves 10 days in advance.

Captured
The US National Snow and Ice Data Center announced that Arctic sea ice reached its annual maximum extent on 21 March. At 14.33m km2, the winter peak is the smallest in the 47-year satellite record. Dr Julienne Stroeve, a senior scientist at the NSIDC, told Carbon Brief that the record low “continue[s] the overall long-term decline in the ice cover”.

Warming may turn butterfly hotspots from ‘safe havens to graves’
This week, Carbon Brief covers a new study that mapped and analysed the biodiversity of butterfly species around the world.
Up to a third of butterfly biodiversity “hotspots” will become too warm for the species they host by 2070, according to new research.
The study, which analysed distributional data on more than 12,000 butterfly species, was published this week in Nature Ecology & Evolution.
It found that two-thirds of butterfly species are mountain-dwellers, with mountains holding 3.5 times more butterfly biodiversity hotspots than lowland ecosystems.
The lead author of the paper told Carbon Brief he hopes that the approach laid out in the study will “broadly boost the representation of insects in global ecology and conservation”.
Mapping hotspots
Butterflies are “uniquely well-documented among insects”, Dr Stefan Pinkert, a researcher at Germany’s University of Marburg, told Carbon Brief.
But, even so, “much of this information remain[s] fragmented and inaccessible”, said Pinkert, who led the new study.
Pinkert and his colleagues used a country-level database of butterfly occurrences, along with regional range maps and previously published species-distribution models, to model the distribution of 12,119 butterfly species. They then calculated and mapped the “richness” and “range rarity” of butterfly species around the world.
Species richness was calculated as the number of unique species in the database for a given area. “Range rarity” is inversely proportional to the range size of the species in an area.
For both richness and range rarity, the researchers defined a “hotspot” as the 5% of areas around the world with the highest value of each quantity. They found that only 10% of species richness hotspots and 10% of range rarity hotspots overlap. The study said that this underlines the “limited value” of species-richness hotspots for identifying conservation priorities.
Pinkert told Carbon Brief that he was concerned to find that only 40-45% of butterfly biodiversity hotspots overlap with the biodiversity hotspots of land animals. Land-animal biodiversity has historically “served as main surrogates for defining” priorities for global conservation, he added.
Warming warning
The researchers also found that around two-thirds of all butterfly species they studied live in mountain regions, with species richness peaking at around 2,500 metres elevation and range rarity peaking at 3,500 metres. They noted that, while mountains are known for their species richness, the concentration of butterfly biodiversity is “substantially” higher than it is for other types of organisms, such as plants, birds and reptiles.
They then used climate models to project warming over the next 45 years – as well as how those temperature changes will affect butterfly habitat in the future.
They found that “temperature niche loss” – warming beyond the safe temperature range for species in a given area – would erode up to one-third of species-richness hotspots globally, under a very-high emissions scenario, with some areas losing nearly two-thirds of their hotspot area. Under a moderate emissions scenario, sub-Saharan Africa and south-east Asia would each lose a quarter of their temperature niches.
The loss of safe temperature niches was greater for hotspot areas than non-hotspot areas. The authors concluded that under accelerating warming, mountains might be converted “from safe havens to graves”.
Pinkert told Carbon Brief:
“Our results underscore the urgent need to prioritise insect conservation amid global change…Business-as-usual in prioritisation and implementation [of conservation actions] will threaten ecosystem integrity – the foundation of our well-being and that of future generations.”

FLIP OFF WOODSIDE TO SAVE SCOTT REEF: Greenpeace, Michael Caton, Thinkerbell mobilise Australia to challenge gas project at Scott Reef
6 November 2026
Greenpeace Australia Pacific has joined forces with Thinkerbell and iconic Australian actor Michael Caton on a major public movement and behaviour change initiative to save Scott Reef, calling on Australians to “flip off” gas corporation Woodside. The company plans to drill for gas at Australia’s largest oceanic reef, home to vulnerable green sea turtles, endangered pygmy blue whales, and thousands of marine species, off the coast of Western Australia.
WATCH THE FULL VIDEO HERE
At the heart of the collaboration is somebody who knows a thing or two about fighting off corporations to protect a home: Michael Caton. Set in a courtroom, Caton gives his voice to a voiceless inhabitant, a green sea turtle, and together they invite the public to show their support to save Scott Reef.
Designed to shift public behaviour and drive national debate, the movement asks the public to tag their MPs – applying direct political pressure on Environment Minister Murray Watt and Prime Minister Albanese Albanese to “flip off” Woodside’s dirty gas project, which would see up to 57 toxic wells drilled around Scott Reef off the coast of Western Australia.
Voiced by Michael Caton and set to a soundtrack provided by Radiohead, the narrative centres on our hero turtle defending her home from corporate overreach in a courtroom showdown. As the turtle defiantly flips her flippers at Woodside, Michael Caton calls on everyday Australians to take a stand and help save her home.
Michael Caton said: “I’m proud to lend my voice to Greenpeace to help save Scott Reef. The marine life out there can’t speak up, so we need to. Some things are too precious to risk.”
Glenn Walker, Head of Nature at Greenpeace Australia Pacific, added: “Woodside’s dirty gas project at Scott Reef, Australia’s largest oceanic reef, is an environmental disaster waiting to happen, threatening thousands of species, including the extremely vulnerable green sea turtles that nest there. By literally flipping off Woodside and Big Gas, Aussies are cutting through corporate spin and sending an unignorable message to Environment Minister Murray Watt and the Albanese government: save Scott Reef.”
Adam Ferrier, co-founder of Thinkerbell, said: “You can fight a corporation in the courtroom forever, but the real power to deliver lasting protection rests in parliament. Right now, our MPs hold an extraordinary opportunity to safeguard Scott Reef for generations to come. I’m proudly from WA, and I know how much the natural environment means to the people and economy of Western Australia. I’m also sure Woodside wants to do the right thing, and with enough public support and government action we’ll together save Scott Reef.
Paul Swann, Chief Creative Tinker at Thinkerbell notes: “When the stakes are this high, polite ads don’t work. You need an unignorable provocation that galvanises people and puts the pressure squarely where it belongs, on our leaders in Canberra. This isn’t just about protecting a reef; it’s about holding power to account.”
Greenpeace has been campaigning to stop Woodside’s dirty gas plans for years, increasing pressure on the Australian government to save Scott Reef from becoming an industrialised gas zone. From actions aboard Woodside’s gas platform to cinemas across Australia, Greenpeace isn’t backing off in their advocacy to save Scott Reef.
Rolling out across OOH, digital, social and cinema with an interactive landing page, this project will be amplified by high-profile figures urging Australians to take action, tag their MPs, and defend Scott Reef. The movement combines cinematic storytelling with organic social mobilsation and earned media, planned via Thinkerbell’s Alchemy model to drive real behaviour change and impact.
Marking their first Australian tour in 15 years, English rock band Radiohead will play 16 arena shows across Perth, Melbourne and Sydney in May and June 2027. A $2 donation is included in every ticket price with proceeds going to Greenpeace Australia Pacific and the Australian Marine Conservation Society. Radiohead will match the final amount raised.

Jimmy Barnes, King Gizz lead Aussie music supergroup on new release to save Scott Reef
SYDNEY, Monday 9 November 2026 — Australian music icons Jimmy Barnes AO, King Gizzard & the Lizard Wizard, Fred Leone, Gordi & Montaigne are among the more than 20 Australian artists who have joined forces to release a new song with an urgent message: save Scott Reef.
Released today, “If Not Now” is a reimagining of King Gizzard & the Lizard Wizard’s Environmental Music Prize-winning song “If Not Now, Then When?”, and is a collaboration between Greenpeace Australia Pacific, Green Music Australia, and p(doom) Records.
Scott Reef is a 15-million-year-old ancient coral reef located 270 kilometres off the Kimberley coast of Western Australia. It is Australia’s largest oceanic reef and is home to thousands of marine animals and endangered species, but fossil fuel corporation Woodside plans to drill up to 57 toxic wells under and around the reef, threatening to turn it into an industrial gas zone.
“If Not Now” is the reef’s first and only release, out on all digital platforms and on limited edition 7” vinyl. The song is accompanied by cover art and visualiser from acclaimed Australian artist and ARIA-winning music video director Jonathan Zawada (Flume, The Avalanches).
Speaking about the track, Stu Mackenzie (lead singer, King Gizzard & the Lizard Wizard) said: “Why are we still digging up coal and gas? Why are we allowing this? Why is the Australian government so hell-bent on destroying our beautiful wild and untouched places? I’m proud that a King Gizz song was chosen to represent a growing movement of people who are asking these questions and applying pressure. Let’s shut it down and keep it beautiful.”
Rock legend Jimmy Barnes AO said: “Scott Reef is one of the few pristine reefs left in the world and it happens to be on our doorstep. We’re custodians of it — we’re supposed to be looking after it. It’s ridiculous. We must protect our country and look after what we value most, which is the nature and the beauty of this country.”
Hannah Schuch, Senior Campaigner for Greenpeace Australia Pacific, said: “I’m filled with hope by the incredible musicians and artists who are using their voices and skills to amplify the voices of half a million Australians who are calling on the government to stop Woodside’s nature and climate-wrecking gas plans and save Scott Reef. Australian music has long been a powerful catalyst for change, so saving Scott Reef is a no-brainer for Australian music lovers.”

The release comes amid growing national pressure on the Federal Government to save Scott Reef from Woodside’s gas drilling plans.
Last week, a leaked letter from WA’s environmental watchdog to Woodside revealed the agency deemed drilling risks to Scott Reef ‘serious, significant and irreversible’, while Greenpeace Australia Pacific activists occupied a major Woodside gas platform, and Perth communities delivered one of the biggest environmental petitions in Australia’s history to Woodside HQ.
The Federal Government is expected to make a decision on Woodside’s Scott Reef drilling plans in the coming months.

What might a high-school course look like if it helped students understand climate change—and see a place for themselves in responding to it?
Not simply a course about emissions or environmental problems. A course that connects science with the places students know, the decisions their communities face, and the work they might one day do.
Canadian schools already teach climate change and environmental responsibility, including through required curriculum expectations. Ontario’s Grade 9 science course, for example, asks students to assess climate change’s effects on ecosystems and communities, including First Nations, Métis, and Inuit communities. Across Canada, however, the depth and placement of climate learning vary, and opportunities for more specialized study often sit within elective courses.
Part 1 explored how we could build on that foundation through sustained learning from elementary school onward, shaped with First Nations, Inuit, and Métis governments, educators, and education authorities.
One next step worth considering is a required senior-secondary course that brings these threads together. Imagine a course called Climate, Land, and Future Economies: a place to explore climate evidence, community resilience, Indigenous governance, practical
