DeBriefed 25 July 2025: World court delivers climate ‘turning point’; Renewables ‘unstoppable’; Antarctica’s oldest ice examined - Carbon Brief
ICJ said “wealthy” nations must cut emissions or risk reparations and around 90% of renewable projects are now cheaper than fossil fuels.

Global warming reached an estimated 1.51°C in May 2025.
'If the 15-year warming trend leading up to then continued, global warming would reach 2°C by December 2036'
May was the first month below this trend in almost two years.
Global warming accelerated significantly!

Fascinating new study from @oceansclimatecu.bsky.social reveals that upwelling—the slow rise of deep, cold water to the surface—is not only much faster than we thought but also sharply concentrated near the equatorial Pacific Ocean.
