Down under, where the carbon is.
Today's little tidbit is a short news story about a Journal of Climate paper [LINK]. The paper is about a climate simulation that includes an ocean (and presumably a carbon cycle model). The bottom line is that they think they have a credible southern hemisphere atmospheric circulation, with then drives a realistic Antarctic circumpolar current. If you have never done so, go get a globe and look at it from the "bottom," so you are looking right at the south pole; notice that there is a ring of water around Antarctica. That's the only place where that happens, and it makes a big difference to the world's climate. Anyway, they say that as the winds around Antarctica move south, they change the uptake of carbon dioxide into the ocean, which partially offsets the climate change associated with the anthropogenic greenhouse effect. That's good! Unfortunately, it also accelerates sea level rise (by pumping heat into the ocean, raising the temperature faster) and ocean acidification (which might feed back onto the carbon cycle if critters start dying off). So there you go. Maybe I'll try to tap Nikki for more nuianced insight, since this is closely related to her work.
