The ocean has been hoarding heat. Now it is building up a massive 'burp.'
Even if humans cut emissions enough to reduce global temperatures, new research shows the Southern Ocean could kick warming back into gear.

Interested in modeling the response of ocean carbon and heat storage to CO₂ emission stoppage or net-negative CO₂ emissions? I have a postdoc opening: www.geomar.de/en/karriere/...

Researching ocean storage of carbon and heat? Considering to attend EGU25 (27 April – 2 May 2025)? Submit an abstract to our session: "Ocean storage and loss of carbon and heat, and relevance for climate": meetingorganizer.copernicus.org/EGU25/sessio... Looking forward to discussing at EGU25!
