Ocean Warming Breaks Record for Ninth Straight Year - Inside Climate News Every second of last year, the Earth’s oceans absorbed the equivalent in energy to 12 Hiroshima-sized atomic bombs.  Global ocean heat content (OHC) increased for the ninth consecutive year in 2025, a...

"Ocean Warming Breaks Record for Ninth Straight Year" is a great article by Johnny Sturgeon for @insideclimatenews.org on a recent report where @michaelemann.bsky.social and coauthors confirm continued ocean warming due to increased greenhouse gas emissions.

Thank you to everyone who came out to support the amazing student presentations in the 1.5* min lecture series! It was great to hear from MRG student Chris Larson on the loss of the Greenland ice sheet and @penncssm.bsky.social student Nat Glasgow on linguistic injustice in climate communication

Seems relevant today...
