I have been doing some reading on the ocean and climate, and stumbled across this account of a Year Without a Summer,→[More:] when temps in the Northern Hemisphere got so low that the upper bay of New York froze, and many many died.

It is ironic that one of the scenarios of global warming is that the thermohaline circulation could be disrupted by fresh meltwater from Greenland, thereby plunging Northern Europe into another little ice age, while in other places, the earth would heat up considerably.

Dallas Murphy, the author of the mentioned book wrote a few years ago in that book that society was finally getting on board with the fact that human-caused climate change is a reality. This was before the most recent election, and before the Rise of Palin and her cadre of deniers.

Very interesting stuff, climate.
