• The details of the Younger Dryas event (an absolutely astonishing bit of recent geologic history that not many know about) are, I think, a bit different. The waters of a huge former inland lake drained suddenly to the Atlantic by way of the St Lawrence about 13,000 years ago. The influx of cold fresh water quenched the warm northbound Atlantic current for scores of years, maybe longer, with the result that the northern parts of Europe and America were plunged into an ice age.

    Same thing is theorized to happen if the glaciers of Greenland were to quickly slide off the land into the Atlantic. This consequence of global warming could paradoxically plunge the north Atlantic into a 100-year ice age, even while the rest of the planet continued warming.
