Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Record Europe heat
HOTTEST EVER: The UK broke its temperature record for June twice this week, while France recorded its hottest day ever two days in a row, reported the Guardian. The Times reported that temperatures reached 36.7C in Somerset on Thursday, as the “London Ambulance Service had its busiest-ever day for life-threatening emergencies”.
FRANCE FRYING: French newspaper Libération said that temperatures reached as high as 44.3C in the south-western commune of Pissos on Wednesday. Spain also recorded its highest daily average temperature for June, said BBC News. On Thursday, Switzerland also had its hottest June day, when temperatures reached 37C in four locations, reported SwissInfo.
CLIMATE LINK: CNN covered a rapid analysis from the World Weather Attribution service finding that fossil-fuelled climate change has made this heatwave the most severe and widespread in Europe’s history. Carbon Brief covered the broken heat records, explaining the influence of climate change.
‘Electrifying’ London talks
‘LONDON COOKING’: In a sweltering, packed-out event at London climate action week, UN chief António Guterres quipped that “London is not just calling, it’s cooking”, reported Edie. Guterres also used his address to release a “global call to action on methane” and to call on artificial intelligence companies to reveal their environmental impact and source their power solely from renewables by 2030, said the publication.
‘ELECTRIFY NOW’: Elsewhere, dozens of governments, led by the EU and the UK, committed to throwing “their political weight” behind a rapid electrification of the world’s economy, according to Climate Home News. A high-level summit in London’s Mansion House saw energy ministers and business leaders, joined by Guterres, in “calling for faster action to curb demand for oil, coal and gas by powering homes, industry and transport with clean electricity”.
FOSSIL TRANSITION: At the same event, ministers from Colombia and the Netherlands, the co-hosts of the world’s first summit on transitioning away from fossil fuels in April, unveiled a report on their key takeaways. It comes after the current Colombian government has been ousted by a presidential election defeat to a fossil-fuel-supporting Trump ally. Carbon Brief examined what this could mean for the world’s energy transition.
Around the world
- UK TARGET: The UK parliament has approved its “seventh carbon budget”, aimed at cutting emissions 87% below 1990 levels by 2040.
- TOTAL ACCOUNTABILITY: A French court has ordered oil-and-gas giant TotalEnergies to account for the emissions from the use of its products, following a case brought by a climate NGO, reported Le Monde.
- METHANE RULES: The US, Qatar and other major energy exporters have urged the EU to “rewrite planned methane emissions” rules for oil-and-gas imports, saying that the policy could disrupt fuel supplies to Europe, according to Reuters.
- CHINA MESSAGE: China’s special envoy for climate change, Liu Zhenmin, said at the World Economic Forum that energy shortages triggered by the Iran war should be a “lesson to countries to accelerate their energy transitions”, reported Bloomberg.
- US WEBSITE REVIVED: Former US government workers have “recreated a valuable climate-science website” shut down by the Trump administration last year, said the New York Times.
6,600 animals
The number of livestock that perished in transport during heat in England and Wales from June to August 2025, double the number killed the year before, reported Carbon Brief.

Captured
The UK government’s official climate advisers, the Climate Change Committee (CCC), has released its latest progress report, emphasising that faster electrification is the best way to secure lower energy bills and stronger energy security. Electrification has shot up the agenda in recent months, with the COP31 presidency calling for countries to back a global goal for 35% of “final” energy to come from electricity by 2035. The text of the CCC’s latest report uses the word “electrification” far more often than previous editions, as shown in the figure above. See Carbon Brief’s in-depth breakdown of the CCC’s latest advice.
Spotlight
Introducing ‘Project Cosmos’
Carbon Brief explains how it built a major new database of climate science research and unveils a new ranking of the 500 most highly cited publications, authors and institutions in climate science.
This week, Carbon Brief launched Project Cosmos – the world’s largest and most complete database of climate change research.
The database features more than 1.8m academic papers, books and reports, capturing the vast body of human knowledge about climate change that has accumulated over more than a century of academic study.
The climate science “universe” is based on reports from the Intergovernmental Panel on Climate Change (IPCC), which are recognised as the world’s most authoritative summaries of the latest climate science.
Since its first report was published in 1990, humanity’s knowledge about human-caused climate change has ballooned. The IPCC has published six sets of reports in total – each one longer than the last.
In total, IPCC reports reference more than 100,000 other papers, books and reports. This is the core of our climate science universe. Carbon Brief then built on this core, by looking at four other sources of data. Read more about how the Cosmos database was created here.
Every single publication in the Cosmos database is linked to at least one other through references. Visualising these links reveals a “galaxy” of references.

Cosmos 500
As part of an initial wave of preliminary analysis to demonstrate the scope of the Project Cosmos database, Carbon Brief has ranked the 500 most highly cited publications, authors and institutions in the database.
The most highly cited climate scientist is Prof Philippe Ciais, who has spent almost four decades researching the planet’s carbon cycle – and the ways in which humans have been impacting its balance. Carbon Brief recently interviewed Ciais in Paris.
The US tops the tables for the most highly cited authors and institutions. Almost half of the 500 most highly-cited authors are from US institutions. This raises particular concerns for the future of climate science, as US climate scientists and institutions are coming under attack under the Trump administration.
Experts from global south countries account for only 4% of all authors in the Cosmos 500. China stands out as the most highly-cited global south country. Meanwhile, only 10% of authors in the Cosmos 500 are women.
There are many possibilities for future avenues of research using the Cosmos database. Over time, the database could be used to reveal, for example, how interest in different areas of climate science has changed over time, plus identify potential knowledge gaps and, thus, opportunities for future research.
Carbon Brief invites researchers – including academics, journalists and analysts – to submit their own proposals for co-authored studies, literature reviews and analytical projects. Proposals should be sent to cosmos AT carbonbrief DOT org.

The post DeBriefed 26 June 2026: Heat records broken across Europe | London climate action week | Introducing ‘Project Cosmos’ appeared first on Carbon Brief.
Prepared by a coalition of nine Western Australian union, industry, conservation, and community organisations—including UnionsWA, the Conservation Council WA, and the Smart Energy Council—the WA Clean Energy, Jobs & Industry Plan provides a practical roadmap to transform Western Australia into a clean energy powerhouse while creating thousands of secure local jobs.
Western Australia stands at a pivotal crossroads: lead the global clean energy economy or watch investment, future industries, and secure jobs go elsewhere. The WA Clean Energy, Jobs & Industry Plan outlines a transformative blueprint to harness the state’s world-class solar and wind resources. Discover how legislated renewable targets, green iron manufacturing, and a dedicated regional training strategy can generate tens of thousands of local jobs, lower household bills, and build a resilient, net-zero future for all Western Australians.
WA needs a clear and forward-thinking plan if it is going to become a competitive renewable energy powerhouse and maintain its economic strength through the energy transition.
“Western Australians know a faster renewable energy transition will lower their household expenses and prevent harmful climate pollution. But the community also needs clear direction to ensure this transition will create jobs, lower costs and not cause undue environmental harm.
“Here, sectors representing a broad range of interests have laid the groundwork for those outcomes, clearly outlining what is needed to create a future for WA that is good for the environment, for the climate, for workers and for the economy.
Summary
The WA Clean Energy, Jobs & Industry Plan sets out a strategic roadmap to position Western Australia as a global clean energy superpower while creating thousands of secure local jobs.
The report establishes three overarching goals:
- Creating local employment.
- Maintaining industrial competitiveness.
- Lowering household energy costs
To realize this vision, the framework details actionable measures to follow on from the recent WA Government announcement of a 75% Renewable Energy Target by 2031 for the South West Interconnected System. This includes developing a statewide Renewable Energy Target, coordinating statewide workforce and training pipelines, strategically planning regional infrastructure to safeguard high-value biodiversity and cultural heritage, and ensuring equitable benefit-sharing through household electrification incentives and First Nations equity partnerships. Ultimately, the plan highlights that establishing clear policy and regulatory certainty will unlock lower energy bills, boost power reliability, and secure the state’s global competitiveness in emerging green commodity export markets.
Key Findings
- Statewide Renewable Energy Target and Emissions Reduction Targets: The report calls for a statewide RET and 1.5°C aligned emission reduction targets to remove policy risk, lower capital costs, and attract clean energy investment.
- Transformative Job Creation: Accelerating the transition offers massive employment prospects, including up to 8,800 solar and battery jobs by 2050, as well as 24,000 ongoing and 11,000 construction jobs in a commercial green iron industry.
- Industrial Electrification & Competitiveness: Requiring large gas users to adopt binding electrification timetables and providing concessional financing will protect existing energy-intensive manufacturers from rising energy costs and impending domestic gas shortfalls.
- Green Commodity Export Leadership: Western Australia can build new export markets in green iron, green ammonia, and offshore oil/gas decommissioning by constructing shared common-user infrastructure and setting dedicated Green Commodity Export Targets.
- Coordinated Workforce & Training Pipeline: To address critical skill shortages the plan recommends establishing a WA Clean Energy Jobs Plan 2050, three regional training hubs, and dedicated pathways for female and under-represented apprentices.
- Environmental Safeguards & Community Benefits: Fast-tracked development must be paired with State Planning Policies that avoid high-biodiversity and cultural heritage lands, mandate new data centres to run on additional renewable power, and deliver household electrification rebates and First Nations equity partnerships.
