I've been reading about the Younger Dryas [1] transition recently. This was the ice age that we're still warming up from; before it started the world was at least as warm as it is now. Then, over just a few decades, the global temperature dropped 2-6C and lots of animals went extinct. Humans got hammered badly too. The cold lasted about 1200 years, then over a few decades it warmed up again, and it's continued to warm up ever since.
