Marine Heatwaves Have Increased in Frequency, Duration, and Depth Across Southeast Asia

In Southeast Asia, marine heatwave (MHW) frequency doubled (+108%) and duration increased (+63%) during 2003โ€“2023 compared with 1982โ€“2002 Local surface net heat flux and high sea level pressure u...

Ocean scientists are one step closer to understanding the connection between warming in the Eastern Tropical Pacific Ocean and its impact on weather and climate. The new study by @oceanclilmatecu.bsky.social and partners in @agu.org Earth's Future is spotlighted here! buff.ly/Tcbj2fq

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

During our Climate Chat, someone asked when we reach +3.0ยฐC with current warming rates. Here I extrapolated the warming rate from 'Global Warming has Accelerated Significantly' by Grant Foster and Stefan Rahmstorf (2025 preprint) to up to +4ยฐC (extending their table 1):

Fangyi Tan and I led a new study showing how the 2023 El Niรฑo triggered record-breaking ocean warming across Southeast Asia. Heat anomalies spread deep into regional seas, with warming reaching 40 m. Our work highlights the urgent need for sustained ocean monitoring. doi.org/10.1038/s415...
