In James Hansen’s latest letter that I chatted about in my last video, he showed that in 1960 about 60% of human fossil fuel emissions stayed in the atmosphere, with 40% being sequestered in the oceans and on land (in soils, vegetation, etc.).
At present, only 50% of the carbon stays in the atmosphere, with the other 50% being sequestered. It turns out, according to the latest peer reviewed science, that more carbon is being exported to the deep ocean than expected in the computer models.
This is good news for the short term (atmospheric GHGs are lower than they would have been) but bad news in the intermediate to longer term, since ocean warming and stratification reduction of the oceanic carbon sink in the future will hit us much harder than we would have expected (yet another Faustian Bargain).
I chat about these findings in the new paper titled: “Biological carbon pump estimate based on multidecadal hydrographic data”

I also chat about the Wikipedia page on the Biological Pump. Link: https://en.wikipedia.org/wiki/Biological_pump
This Wikipedia page explains things so well that it deserves a separate video itself, so I’ll leave the TAB open on my computer until I film such a video.

Happy New Year (can I still say this on Jan 3rd; at what date is it too late to say?)
