Oh, crap… (ocean currents edition)
Following close on the heels of news that atmospheric CO2 levels are at a 650,000-year high, comes this cheerful little tidbit:
“The ocean current that gives western Europe its relatively balmy climate is stuttering, raising fears that it might fail entirely and plunge the continent into a mini ice age.
The dramatic finding comes from a study of ocean circulation in the North Atlantic, which found a 30% reduction in the warm currents that carry water north from the Gulf Stream…”

Global warming is real, as evidenced by the huge reduction in arctic ice coverage. But it may have amplifying and paradoxical effects as the thermal and salinity-balance of ocean currents changes from melting ice.
