"As temperatures rise, carbon dioxide leaks out of the ocean like a glass of root beer going flat on a warm day."
"However, as water temperature increases, its ability dissolve CO2 decreases. Global warming is expected to reduce the ocean’s ability to absorb CO2, leaving more in the atmosphere... which will lead to even higher temperatures."

- RandomThoughts3 2y agoPlease, read your own quote: “Global warming is _expected to reduce_ the ocean’s ability to absorb CO2”. I nicely underlined the important part which confirms what I said in my previous comment to help you.
- GeoAtreides 2y agoI would suggest reading the NASA article I linked, as it explains the issue a bit more in detail than a simple HN comment could ever do.
- RandomThoughts3 2y agoI already had before you posted it. It doesn’t support the idea that the oceans will release carbon in the atmosphere overall. Note that the effect of emissions on the ocean capture capacity is taken into account in the IPCC modelling work including the work done since the article you link was published in 2008 and none of the IPCC scenarios predict a reversing of the ocean sinking ability, not even the worse SSP considered. You would be right to point out that using the same argument (IPCC modelling) you could say my scepticism regarding net zero is lacking foundations which would be fair. I would reply to that that I don’t actually believe we will reach net zero in 2050.
