> "In the British case, even though the southernmost point of England lies some 300 miles north of the northernmost point of Japan, the Isles have significantly warmer winters, thanks to the Atlantic Ocean and its Gulf Stream, which carries warm equatorial water up the eastern seaboard of North America and thence eastward toward Ireland. This warmer water raises the temperature of westerly surface winds enough so that the Isles experience ample cold, winter rain but very little snow."

The article doesn't go into the basics of gyre formation in the ocean basins, which is driven by the Coriolis force and the global atmospheric circulation, but western intensification boundary currents (e.g. Gulf Stream) arise from that physical phenomena, and thus the Gulf Stream wouldn't be 'shut down' by large glacial meltwater releases, at most it would just be pushed south.

P.S. Land permafrost likely sequesters at least as much carbon as the deep ocean does during ice ages, and the whole 'oceanic conveyor belt' theory of how atmospheric CO2 drops during ice ages isn't as solid as some claim.
