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
