If Global Warming shuts down the Gulf Stream – not currently expected this century, but very possibly in the 22nd – will we have mile-high glaciers as far south as the Mid-Atlantic United States, the Upper Midwest, etc.? Ocean waves freezing in mid-surge in New York Harbor?
I’m no scientist, but from what I’m reading, they’re talking in terms of a “Little Ice Age,” maybe not even this bad, but similar to just one “year without a summer,” and apparently ‘only’ restricted to Western Europe – though I have to think Eastern North America as well, since the Gulf Stream influences weather there also.
IOW, perhaps liveable climatically, but damned unpleasant even for the hardiest hockey fan!
But combine reduced agricultural output there with that coming from Peak Oil and the end of petro-fertilizer, and that could be more than unpleasant!
