Analysis: UK renewables enjoy record year in 2025 – but gas power still rises
The UK’s fleet of wind, solar and biomass power plants all set new records in 2025, Carbon Brief analysis shows, but electricity generation from gas...
Wildfire smoke is a national crisis, and it’s worse than you think
Wildfire smoke is an emerging nationwide crisis for the United States. Supercharged by climate change, blazes are swelling into monsters that consume vast landscapes and...
India, Saudi Arabia and Argentina fail to submit climate plans in 2025
India, Saudi Arabia and Argentina are among the roughly 70 nations that did not submit updated climate plans to the United Nations in 2025, despite...
Drawing the line: how levee accreditation shapes flood insurance winners and losers
Millions of Californians live behind levees constructed to redirect water and prevent floods. Accurate assessments of these levees are crucial in flood hazard maps, which...
