Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Record temperatures
RECORD LEVELS: The Copernicus Climate Change Service has warned that extreme weather across the globe is set to continue, following April marking the 11th month in a row where global average temperatures were at record highs, reported the Financial Times. April was 0.67C above the 1991-2020 average for the month and 1.58C above pre-industrial levels, it added.
SURGING SEA TEMPERATURES: Analysis of the Copernicus data by BBC News found that the world’s oceans have broken temperature records every single day over the past year and, on some days, this has been by a “huge margin”. In February and March 2024, sea surface temperatures reached a new global average daily high of 21.09C, according to the analysis.
Climate scientists speak out
PAST 1.5C: A survey by the Guardian has found that the majority of the world’s leading climate scientists expect global temperature to rise to at least 2.5C above pre-industrial levels by 2100, given the current level of action by countries. The survey of 380 Intergovernmental Panel on Climate Change (IPCC) scientists found that almost half anticipate 3C of warming, while only 6% thought the internationally agreed 1.5C limit will be met.
EXHAUSTED EXPERTS: In an accompanying piece in the Guardian, the experts shared their views. One scientist from Mexico told the newspaper she felt “hopeless and broken” by the pace of rising climate impacts, while another expert said thinking of the future was “infuriating, distressing, overwhelming”. A separate piece spoke to the female scientists surveyed, a fifth of whom have decided not to have children or to have fewer.
AVOIDING DESPAIR: The Guardian published an editorial alongside the above articles, urging readers not to despair. Although the “future can feel overwhelming and unfixable”, it notes, we need to “build collective awareness, a sense that change is possible and momentum for wider systemic progress”. Additionally, an opinion article by former UN climate chief Christiana Figueres similarly argues that “stubborn optimism may be our only hope”.
Around the world
- BRAZIL FLOODS: Record-breaking floods in southern Brazil have killed more than 105 people and affected more than 1.7 million, with more rain expected, reported O Globo.
- EU AND CHINA TALK TRADE: EU commissioner Ursula von der Leyen has restated readiness to launch a trade war with China over imports of clean energy technologies during a meeting with president Xi Jinping, reported the Guardian. Elsewhere, the South China Morning Post reported that the new climate envoys from China and the US have met for the first time.
- SOUTH ASIA HEATWAVES: Governments across south and south-east Asia have issued health warnings as schools shut and crops fail, as extreme heat continues to grip the region, the Guardian reported. In the Himalayan state of Uttarakhand, five people have been killed by forest fires, reported the Hindustan Times.
- AUSTRALIAN GAS: Australia’s government has announced plans to ramp up the extraction and use of gas to “2050 and beyond”, BBC News reported. The prime minister is now facing an internal revolt from his party, the Guardian added.
- KENYA DAY OF MOURNING: Kenya’s president William Ruto has declared a public day of mourning following the deaths of 238 people due to ongoing flooding, which will be marked by tree-planting, reported the Associated Press.
- LONDON MAYOR: Labour’s Sadiq Khan has pledged further “world-leading green action” after winning a historic third term as London Mayor, reported Bloomberg. Khan’s victory came despite speculation his ambitious air pollution and climate measures could turn off voters.
30%
The proportion of global electricity that came from renewables last year – a new record, according to analysis covered by Carbon Brief.
Latest climate research
- Fewer cooler days due to climate change could make existing varieties of lychee “unsuitable for cultivation in production areas in southern Taiwan”, a new study in Climate Services said.
- Tornado-producing tropical storms may increase “substantially” in the US by 2050 as climate change worsens, new research in Weather and Climate Extremes found.
- New research published in Nature Climate Change found that the transport of ocean heat through the Bering Strait has a more substantial influence on Arctic warming than previously recognised.

Captured
“Residual emissions” are those that remain once a nation has gone as far as it thinks is possible to cut its emissions. These emissions tend to come from sectors that are considered hard to decarbonise, such as livestock farming and heavy industry. The concept is closely tied with net-zero targets. That is, a country must remove CO2 from the atmosphere that is equivalent in volume to its residual emissions, in order to say it has reached net-zero. A new study covered by Carbon Brief explored national strategies for managing residual emissions. Of the 71 countries examined, just 26 have long-term plans to tackle these emissions. These nations could have residual emissions of up to 2.9bn tonnes of CO2 equivalent by 2050, equal to around 5% of total global emissions. Countries include major emitters such as the US, Canada and Australia (as shown in the above chart). The chart shows residual emissions (red) as a share of each nation’s peak emissions (blue) – or its most recent annual emissions, if its emissions have not yet peaked.
Spotlight
The Thames Barrier at 40
Carbon Brief visits London’s Thames Barrier, the second-largest flood defence barrier in the world, as it turns 40-years-old.
With sea levels rising and flood risks increasing, the UK’s Environment Agency (EA) is working to develop the next era of protections for London and the wider Thames Estuary.
On 25 April, Carbon Brief visited the Thames Barrier to discuss its origins and look forward to its next 40 years.
History
In 1953, London and the east coast of England were devastated by the North Sea Flood, which killed more than 300 people and caused an estimated £50m in damage (approximately £5bn in today’s money) in the region.
While, previously, the UK government had broadly taken a reactive approach to floods, progressively raising the walls and banks of the Thames river, this flood made it clear that such an approach was not sustainable.
In response, one of the first ever “rising sector gates” was built across a 520m-long stretch of the River Thames near Woolwich.
The Thames Barrier was designed by Charles Draper of the London-based Rendel, Palmer and Tritton architectural company, who took inspiration from a gas tap on his cooker. He built a working model in 1969, ahead of construction five years later. The barrier started being used in 1982.
On 8 May 1984, the Queen Elizabeth II officially opened the £535m (£2.4bn in today’s money) Thames Barrier, which remains the second-largest flood defence barrier in the world.
Operation
Now, 40 years on, the Thames Barrier continues to protect 1.4 million people and £321bn of property from tidal flooding.
The Thames Barrier includes 10 steel gates positioned across the width of the river that can be rotated to rise out of the water. Once raised, each 3,300-tonne main gate stands as high as a five-story building and is as wide as the opening of London’s iconic Tower Bridge.
Over the past four decades, it has been closed 221 times for flood defence purposes, including a particular spike in 2013-2014 when it was closed 50 times in 13 weeks.
Andy Batchelor, Thames tidal defences operations manager, who started work at the barrier the day the Queen opened it, said in a statement:
“Having witnessed and worked on the Thames Barrier’s opening, I am immensely proud of the protection it has provided London for the past 40 years and will continue to provide for years to come.
“Its reliability and effectiveness demonstrate the sophistication of its design by a very talented group of engineers and the continued maintenance and operation carried out by the barrier team.”
The next 40 years
The Thames Barrier was only designed to last until 2030. However, the EA, which operates and maintains the site, is confident it will continue to run until 2070.
However, sea levels are predicted to rise 1.5m by the end of the century, increasing the potential for a significant tidal flood. Additionally, with England becoming increasingly wet, the barrier is expected to be called on increasingly – about half of the closures to date have been for river flood protection.
If closing the barrier 50 times in a year becomes the norm, it could fail, the EA has warned, as this does not provide the necessary time for workers to maintain it.
As such, the agency is working on preparing for the next era of flood protection.
The agency is planning to work with partners to continuously review the best available options, including building a new barrier or developing more flood storage, and decide on an end-of-century option by 2040.
Meanwhile, from 2021-27, the government is set to invest £5.6bn in creating new flood and coastal defences to protect hundreds of thousands of properties.

“Sink or swim”: WA Gov hugely underestimating decline in regional gas demand while sleeping on green exports, new report finds
PERTH, Tuesday 13 October 2026 — A new report from Greenpeace Australia Pacific and Springmount Advisory reveals green commodity exports are an untapped economic opportunity for Western Australia in a declining Asian gas market, while offering a genuine solution for decarbonising Asia.
From Gas to Green: Building Western Australia’s Future State is a comprehensive analysis of the declining gas market in Asia, and the untapped economic opportunity for WA to become a global leader in green commodity exports while driving the regional shift away from fossil fuels.
The report offers key recommendations for the WA Government to support regional decarbonisation through an orderly phase out of gas exports in favour of green iron and other green exports. It comes as global climate leaders from across business, politics and advocacy prepare to meet for the Global Citizen Now: Perth event focused on decarbonising WA.
Key findings:
- Gas demand is falling across WA’s core markets in Asia: Gas demand fell in 2025 and is projected to continue to decline, driven by a combination of global geopolitical factors and domestic concerns.
- Policy shifts in key markets since the war on Iran now prioritise renewables and nuclear over gas: Japan, South Korea and China have legislated energy plans that prioritise renewables and nuclear over gas.
- New WA gas would arrive in a saturated, uncertain Asian market filled with cheaper gas: The US is now the world’s largest liquefied gas producer and plans to double its capacity as it also targets Asian markets.
- Green commodities offer a real solution to sustain WA’s economy: WA can lead Australia’s green commodity exports, which by 2060 could be worth almost a trillion dollars.
- Exporting more WA gas is likely to delay or impede Asia decarbonisation: Despite claims by the gas industry, there is no evidence that WA gas is displacing coal in Asia, and in fact diverts resources from genuine decarbonisation options.
Geoff Bice, WA Campaign Lead at Greenpeace Australia Pacific said: “As our export partners in Asia shift away from expensive and polluting gas, the WA Government has a golden opportunity to pivot our economy to green exports, like green iron, which is the most effective way to help our region to decarbonise.
“The writing is on the wall: gas is in decline, renewables are our future. In this context, it makes zero sense for the government to encourage high risk projects like Woodside’s reckless Browse gas proposal at Scott Reef.
“This report clearly shows that the WA Government faces a choice: sink or swim. They can either allow the gas industry to keep ripping off West Australians and continue propping up its decline, or choose the path that will deliver enormous benefits to the state and the world by becoming a leader in the rapidly expanding green economy.”
Tom Quinn, Managing Director of Springmount Advisory: “Western Australia prospers when it looks to the future and builds for future demand. Twenty years from now, what the world needs is green commodities made using WAs abundant renewable resources. Just like it did with iron ore in the 1950s and gas in the 1970s, WA should look to the future and build what the world will need, not sunsetting industries like gas that are already past their peak.”

A report from Greenpeace Australia Pacific and Springmount Advisory reveals the untapped green economic opportunity for Western Australia in a declining Asian gas market, which also offers a genuine solution for decarbonisation in Asia.
Is Western Australia clinging to a fading gas industry while a thriving green future passes it by? As major Asian trading partners rapidly pivot away from volatile gas imports toward cheap solar and battery storage, this report exposes a high-stakes choice: risk becoming stranded in an oversupplied fossil fuel market, or harness WA’s unmatched sun and wind to lead the global clean energy transition.
Summary
From Gas to Green: Building Western Australia’s Future State reveals that Western Australia (WA) faces a critical juncture as falling Asian gas demand, geopolitical gas supply volatility and accelerating renewable energy deployment undermine the long-term economic viability of gas exports. By harnessing its world-class wind and solar resources, the report demonstrates that WA can execute an orderly phase-out of gas and pioneer a green commodity export economy that could generate $987 billion in economic value by 2060, create 24,000 ongoing jobs, and drive a 9.6% reduction in global greenhouse gas emissions.
Key Findings
- Gas demand is falling in Asia – WA can no longer rely on gas exports: Gas demand in core Asian markets fell in 2025 and is projected to continue to decline in 2026. Legislated energy plans in Japan, South Korea, and China now prioritise renewables and nuclear over gas.
- Asia is increasing renewables, importing gas just gets in the way: Evidence from markets like Thailand suggests that gas imports are increasingly crowding out cheaper renewable energy investments and battery storage rather than displacing coal, locking in more emissions over time.
- Green commodities offer a real solution to decarbonise Asia – this is a major win for WA: With world-class renewables, WA can lead Australia’s green commodity exports, which by 2060 could be worth almost a trillion dollars ($987 billion) and support a genuine 9.6% reduction in global emissions.
Recommendations to WA government
Recommendation 1: Plan an orderly gas phase-out aligned with a trading partner pivot plan
Implement a managed, orderly phase-out of gas exports aligned with trading partners’ decarbonisation pathways, rather than waiting for demand to collapse, by:
- Developing and implementing a staged phase-out of gas facilities aligned with feedstock supply expiry or typical end of facility lifespans.
- Committing to no new gas development for gas expansion, including Browse and Kimberley fields.
- Developing new, reciprocal trade relationships with existing gas trade partners, structured to progressively replace gas exports with green commodities – integrated with recommendation 2.
Recommendation 2: Develop an integrated green commodity export strategy, positioning WA as a global green iron manufacturing hub
Establish an integrated green commodity export strategy that immediately prioritises green iron development, positioning WA as a global green iron manufacturing hub, by:
- Committing to green commodity export targets to give industry and investors a clear demand signal.
- Prioritising green iron as the lead sector within the broader green commodity strategy, given WA’s iron ore endowment and first-mover potential.
Recommendation 3: Reject false solutions such as carbon dumping (CCS) and blue hydrogen
Reject carbon dumping (also described as carbon capture and storage, or CCS) and blue hydrogen as viable decarbonisation technologies, and prioritise green hydrogen and proven renewables for clean energy and fuel production by:
- Excluding blue hydrogen projects (and CCS-dependent projects) from all government support programs.
- Requiring existing hydrogen-based production (including ammonia, methanol, synthetic fuels) to have clear, near-term transition timelines to switch to green hydrogen production.
