The earth was four degrees C colder at the peak of the ice age 21,000
years ago.   So the above is simply not true.

So the little jog down before present time does not cover the 4 C drop ?

I'm sure you have the ability to find one.  Just remember to restrict

Remember the _Readers Guide to Periodic Literature_?

 
That graph comes from the Washington Post which is not a political
entertainment website.  At least not for conservatives.

They've survived through them for about 2 million, at the

10,000  years ago, the Sahara was a grassland, like our Great
Plains. Now, its a wasteland. That took a change of about 2C.
Many of the great grain growing areas of the world could face
the same fate if temperature goes up another 2C.

Another way to look at it is that every kind of human except for one
(so far) ultimately went extinct so we can't say "Oh, well, humans
survived a lot of crap in the past" because most human species
didn't. Granted, Homo Erectus had a pretty good run of two million
years. Modern humans have been around (depending on definition of
modern) anywhere from 300,000 to as little as 60,000 years, so our
track record wrt climate change is not anywhere near as established
as HE's.
