In 2025, the Ocean Stored a Record-Breaking Amount of Heat, Again - Eos
The ocean soaked up more heat last year than any year since modern measurements began around 1960, according to a new analysis published in Advances in Atmospheric Science.

The ocean keeps getting hotter: In 2025, it absorbed 23 zettajoules (that’s 23 * 10²¹ joules) of heat, breaking a record for the ninth consecutive year. 🧪🌎🌊 eos.org/research-and...
Despite being blasted by radiation to the point that its rocky surface is likely molten, TOI-561 b still seems to retain a thick atmosphere.

There’s less than a tenth as much Sargassum as there was a few years ago, a shift that may be linked to increasing sea surface temperatures in the Gulf of Mexico.
