El Niño set to be 'strongest in living memory', says Met Office
Scientists say the growing El Niño weather pattern is an "unprecedented event" and means 2027 is likely to be the world's hottest year on record.

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. cires.colorado.edu/news/pacific...
