Or "Why does 2 degrees matter?"

Because when were 4 degrees cooler, NYC was under 1000 feet of ice. We really don't want to find out what 4 degrees hotter is like.

Wait really? 1000 feet is insane.

		It was actually about 2000 feet. The Laurentide ice sheet, it was 3 kilometers / ten thousand feet thick in some parts.
