As long as interior mixing processes are weak, this vertical structure persists and the sea ice is protected [...] heat around the globe. In the Arctic, the role of internal waves is less clear. This far north and under a strong sea ice cover, only few internal waves are generated. Due to global warming, however, the [...] continues to drive sea ice decline, internal wave generation and mixing could increase such that enough heat from the Atlantic Water is fluxed toward the surface that even more sea ice melts.

Extreme sea surface temperatures in 2023 resulted in high CO₂ outgassing, particularly in the North Atlantic, meaning that the global ocean absorbed less CO₂ overall. Thanks to El Niño, much less CO₂ than [...] than usual escaped into the atmosphere in the eastern Pacific, but the outgassing in the North Atlantic negated the positive effect. The fact that the ocean did not lose even more CO₂ is due to physical
