Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Congress passes Trump’s ‘megabill’
TAX CREDITS CRUSHED: A major budget bill passed by US congress this week is “poised to remake American energy by slashing tax breaks for wind and solar power and electric cars”, reported the New York Times. The legislation, which was “muscled” through by Republicans, “provides a boost to fossil fuels and dismantles many of the biggest actions the federal government has ever taken to fight climate change”, the newspaper said.
‘CRACKDOWN’: The version of the bill approved by the Senate on Tuesday included “compromise language” that gave wind and solar projects one year to begin construction to claim current tax credits, noted Politico. “Hard-line” Republicans in the House of Representatives told the outlet that they backed the bill only after receiving assurances from Donald Trump that he would use executive action to further “constrict” wind and solar.
LAB LIABILITY: The bill, which is expected to be signed by Trump today, also “seeks to defund” multiple climate labs, according to CNN. This includes the Mauno Lao laboratory in Hawaii, where measurements since 1958 have produced the iconic “Keeling Curve” of rising atmospheric CO2, the outlet noted. See below for more on the emissions impact of Trump’s bill.
Record-breaking heatwave ‘grips’ Europe
RED ALERTS: At least eight people died across Europe as a heatwave gripped much of the continent, reported Reuters, “triggering health alerts and forest fires and forcing the closure of a nuclear reactor at a Swiss power plant”. The New York Times quoted UN secretary general António Guterres, who said: “Extreme heat is no longer a rare event – it has become the new normal.”
RECORD-BREAKING: Both Spain and England had their hottest June on record, noted BBC News, with the Spanish weather service saying the average of 23.6C “pulverised records”. The outlet added that France registered its second-hottest June, while the Guardian reported that Portugal hit a provisional record high for June of 46.6C.
FLASH FLOODS: Elsewhere, a record downpour in the central Chinese province of Hubei brought a month’s worth of rain in just 12 hours to the city of Xianfeng, reported Reuters. Authorities moved 18,000 people to safety, the newswire said. Flooding in India’s northern state of Himachal Pradesh left five people dead, reported the Hindustan Times.
Around the world
- ‘WATER[ED] DOWN’: The European Commission’s newly proposed target to cut the EU’s carbon emissions by 90% by 2040 has been criticised for allowing up to 3% of the goal to be met with international carbon credits, reported Carbon Brief.
- BRAZIL OIL BID: Brazil’s COP30 president-designate, André Corrêa do Lago, has “played down concerns” on Brazil’s oil expansion after a new analysis found the nation will drive a surge in new production by 2030, reported the Financial Times.
- ‘REPUTATIONAL RISK’: The nomination of an economist from the Saudi Aramco oil company as a coordinating lead author for an Intergovernmental Panel on Climate Change report has been denounced as “political capture”, reported Politico.
- FLIGHT FEE: A group of countries, including France, Kenya and Barbados, have pledged to tax private jets and premium-class flying in a bid to raise funds for climate action at a summit in Spain, Reuters reported. Climate Home News has all the key climate-finance takeaways from the event.
- ‘MAJOR SETBACK’: A £65m satellite launched last year to detect methane emissions from oil and gas production has been “lost in space”, reported BBC News.
£528m
The amount by which “climate aid” given by the UK government to developing countries was inflated through controversial changes to the way climate finance is now being designated, Carbon Brief analysis showed.
Latest climate research
- Sustained cuts to US military spending could result in annual energy savings by 2032 equivalent to the energy consumption of Slovenia, a study in PLOS Climate found.
- Using satellite data, a study in the Proceedings of the National Academy of Sciences revealed a marked increase in surface salinity across the Southern Ocean since 2015, coinciding with a “dramatic decline” in Antarctic sea ice.
- Research in Nature Cities highlighted the “disproportionate flood exposure” faced by urban slum populations in the global south, with one in three living on a floodplain.

Captured
Trump’s dismantling of climate policy means the US will add an extra 7bn tonnes of emissions to the atmosphere from now until 2030, compared to meeting its former climate pledge under the Paris Agreement, according to new Carbon Brief analysis of modelling from Princeton University. The approval of Trump’s megabill repealing clean-energy tax credits, alongside a series of executive orders, means that US emissions are now set to drop to just 3% below current levels by 2030 – effectively flatlining – rather than falling 40% as required to hit the now-defunct target, according to the analysis.
Spotlight
Tipping points that worry scientists the most
This week, delegates at the Global Tipping Points 2025 conference in Exeter tell Carbon Brief which potential tipping “element” in the Earth system they are most worried about.
Prof Tim Lenton, founding director of the Global Systems Institute and chair in climate change and Earth system science at the University of Exeter:
“The Atlantic Meridional Overturning Circulation, or AMOC, for sure. The consequences of crashing that would be devastating globally – and also for where I live in the UK. By our own calculation, we could have less than half the viable area for growing a couple of major staple crops, wheat and maize, worldwide. We would have a widespread water crisis. We could have collapses of the monsoons in West Africa and India that would displace hundreds of millions of people. It is hard to see that in anything other than a catastrophe.”
Prof Ricarda Winkelmann, founding director of the Max Planck Institute of Geoanthropology and professor of climate system analysis at the University of Potsdam:
“So I am thinking about this from a risk perspective – so both the likelihood as well as the impacts – and I think the answer depends on that. Because when it comes to the likelihood and the particular threshold – and we know about those – I’m mostly concerned about the Greenland and the West Antarctic ice sheets. This is because we know that, even at lower warming levels, they’re already at risk of transgressing tipping points in certain regions.
“But when it comes to the impacts and also the timescales over which those play out, there are other tipping elements that worry me most. In particular, regional tipping elements. So, if we think of the mountain glaciers, for instance, these impacts are already experienced right now and several mountain glaciers are undergoing these accelerated changes.”
Prof Gabi Hegerl, chair in climate system science in the school of geosciences at the University of Edinburgh:
“I am worried about all of them. But, for the immediate future, I am particularly worried about tipping points that involve the biosphere and humans due to breaching thresholds for heat or drought that then ripple into food availability, livelihood and ecosystems. The Earth system tipping points will do that, too, but maybe a little bit later. Examples are coral diebacks triggered by marine heatwaves, forest change and fires, and droughts threatening livelihoods and putting people on the move.
“I did a research project on the US dustbowl and the trigger was drought causing vegetation and crop dieback, then [leading to] extreme heat and dust storms in response – and migration, as memorialised in [the 1939 John Steinbeck novel] The Grapes of Wrath. And, now with warming, all droughts get supercharged.”
Prof Carlos Nobre, Brazilian scientist and meteorologist who spearheaded the multi-disciplinary, multinational large-scale biosphere-atmosphere experiment in the Amazon:
“The Amazon is a very serious tipping point, because [dieback] could release around 250bn tonnes of CO2 by 2100 – which will make it impossible to [limit global warming] at 1.5C. We could also lose the largest [host to] biodiversity on the planet, which would induce a tremendous, large number of epidemics and several pandemics. Also, of course, the Amazon forest controls aspects of the global climate. In South America, the climate is entirely controlled by the Amazon forest.”
Carbon Brief will publish further coverage of the Global Tipping Points conference next week.

Nearly 100 civil society groups from Türkiye and Australia urge COP31 Presidency to take bold steps to transition away from fossil fuels
Bonn, Germany, Friday 12 June 2026 — A diverse coalition of almost 100 civil society organisations representing Türkiye and Australia have released a joint statement at the Bonn climate conference urging the COP31 Presidency put the transition away from fossil fuels at the centre of the COP31 agenda.
The statement, signed by 94 organisations and addressed to Minister Murat Kurum (Türkiye) and Minister Chris Bowen (Australia), both attending the Bonn Climate Change Conference this week, emphasises that close cooperation between Türkiye and Australia brings a historic opportunity to make international progress in the transition away from fossil fuels, while walking the talk domestically and paving the way to a clean future within their respective borders.
By combining the diplomatic reach of both host nations with the long-standing climate leadership of the Pacific, COP31 should champion the action required to limit warming to 1.5°C.
The statement calls on the COP31 Presidency to:
- Commit to own and advance the just, orderly and equitable transition away from fossil fuels.
- Turn the Just Transition Mechanism – agreed upon at COP30 to enhance international cooperation as well as support and enable equitable and inclusive just transitions – into concrete actions through defined funding, clear timelines, and practical operational details that protect workers and vulnerable communities.
- Enable meaningful progress in international climate finance to advance all pillars of climate action on mitigation, adaptation, and loss and damage, ensuring that “big polluters pay”.
- Rebuild trust in the multilateral process by having a Presidency team that acts as an ‘honest broker.’ This includes protecting the integrity of negotiations from fossil fuel industry influence, which has had a worrying record presence in the last few COPs, and ensuring the full participation of civil society, Indigenous Peoples, women, youth, local communities, and upholding human rights.
The letter also urges Türkiye and Australia to inspire strong global outcomes in negotiations in Antalya in November, by leading by example, developing national roadmaps to transition away from fossil fuels and taking bold decisions domestically.
Shiva Gounden, Head of Pacific, Greenpeace Australia Pacific, said: “The Pacific is at the forefront of global efforts to transition away from fossil fuels. From the beginning, we have worked to advance multilateral cooperation and strengthen the global climate regime — writing the 1.5°C redline into the Paris Agreement, establishing funding for loss and damage, and taking the world’s biggest problem to the world’s highest court. To the COP31 partnership, we bring the experience of 30 years of frontline leadership, the values of reciprocity and collective responsibility, and the warm hearts and unending resolve of our communities. We will continue to be the voice of science, justice and ambition. For us, phasing out fossil fuels and holding the line on 1.5°C is about survival. Together, we can ensure a safer, thriving future for the peoples of the Pacific and for communities worldwide.”
Tanyeli Behiç Sabuncu, WWF-Türkiye Climate and Energy Practice Manager, said: “As the President of COP31, Türkiye should not postpone leaving coal. One-third of the electricity mix in the country comes from it and new coal-fired power plant units are still being planned, despite losing both its economic and social licence. Phasing out fossil fuels is not merely an emission reduction goal. It is also a pathway toward a liveable world for people and nature as well as energy security for consumers and businesses. COP31 presents Türkiye a defining choice: stick to the choices of the past or lead a transformative shift toward a just and clean energy future. Announcing a coal phase-out date would send the clearest initial signal that the country takes its leadership role at COP seriously.
Denise Cauchi, CEO Climate Action Network Australia, said: “The fossil fuel era is ending. The escalating energy crisis is exposing the true costs of fossil fuel dependence—not only through worsening climate impacts, but also through global insecurity, energy price shocks and rising living costs. As the incoming President and President of Negotiations, Türkiye and Australia must put the 1.5°C temperature goal at the heart of COP31, which requires a managed, equitable transition away from coal, oil and gas, backed by finance and supported by a just transition. Australia must lead with credibility. As the world’s third-largest fossil fuel exporter, it needs a clear plan to phase out fossil fuels, including exports, and contribute its fair share of international climate finance.”

‘A new chapter’: Inaugural National EPA CEO John Bradley faces significant choices on the horizon
SYDNEY, Friday 12 June 2026 — In response to the appointment of the inaugural CEO of Australia’s first National Environmental Protection Agency (National EPA), the following can be attributed to Glenn Walker, Head of Nature at Greenpeace Australia Pacific:
“Greenpeace welcomes the appointment of the inaugural CEO of Australia’s first National EPA as the beginning of a new chapter in the conservation of our world-famous nature.
“Now is a time of environmental crossroads — the inaugural National EPA under new CEO John Bradley’s leadership has a duty to provide robust environmental protection advice to the Albanese Government, and can start by protecting Scott Reef and the World Heritage Great Barrier Reef.
“Mr Bradley has the important task ahead of leading the National EPA’s recommendation on Australia’s largest proposed fossil fuel project, Woodside’s toxic Browse project in Western Australia. Browse threatens Australia’s largest freestanding reef, Scott Reef, and our climate, and must be rejected by any agency concerned with protecting the environment.
“Mr Bradley must also use his new position to crack down on rampant deforestation, which is threatening the Great Barrier Reef and sending our native animals, like the koala, to the brink of extinction in Queensland and New South Wales. As a former head of Queensland’s state environment department, Mr Bradley understands the threat of deforestation, and has a unique opportunity to finally protect the Reef from that threat.”

‘A new chapter’: Inaugural National EPA CEO John Bradley faces significant choices on the horizon
China’s power-sector emissions fell in 2025 for the first time in a decade, but a rebound in coal-fired generation raises doubts about whether the decline will last.
China’s coal power output rose in early 2026, fueling concerns that last year’s drop in power-sector emissions may be temporary despite record growth in renewable energy.
