UK told to prepare for 40C summers
The Climate Change Committee warned ministers that Britain should prepare for summers consistently reaching 40C unless urgent adaptation measures are taken. It recommended cooling in schools and hospitals, heat pumps, green shading, a workplace temperature limit, flood defenses, sustainable water storage, and water-efficient new homes, with estimated spending of about £11 billion a year. The committee said 92% of homes could overheat by 2050 and that heat, flood, and drought risks could drive as many as 10,000 excess deaths a year by mid-century.
Why it matters
The warning turns climate adaptation into a near-term infrastructure, health, and labor policy agenda for the UK.

Aol coverageMoss Landing fire drives battery safety overhaul
California's Moss Landing battery fire is still being cleaned up 16 months later, with more than 31,000 battery modules removed by May 8 from Vistra Corp.'s 300-megawatt site. The Los Angeles Times reported that Gov. Gavin Newsom signed a new state law requiring battery-storage safety standards and closer coordination with local fire departments, while a bipartisan House bill would devote $30 million a year for five years to battery research and stress testing. The fire has become a flashpoint as California's battery storage capacity rose from 500 megawatts in 2020 to more than 15,700 megawatts in 2025.
Why it matters
The incident could reshape safety rules for grid batteries as states rapidly expand storage to support renewable power.

Los Angeles Times coverageUN backs ICJ climate responsibility opinion
The UN General Assembly voted to support an International Court of Justice advisory opinion on climate responsibilities under international law, with 141 countries in favor, eight opposed, and 28 abstaining. The resolution follows the ICJ opinion delivered last July and a campaign led by Vanuatu; the United States reportedly urged countries not to back it. The vote gives fresh diplomatic weight to arguments that states have legal obligations around climate harms.
Why it matters
It strengthens the international-law basis for future climate accountability disputes and pressure on governments.

Still unclear
OPEN QUESTION
Will the UK fund adaptation?
The CCC's proposed £11 billion a year is substantial, and the government still has to decide which measures it will actually adopt.
OPEN QUESTION
Can battery rules keep pace with storage growth?
California is scaling battery storage quickly, but the Moss Landing cleanup shows current safety and siting rules may still be insufficient.
