So the little jog down before present time does not cover the 4 C drop ?
If not, do you have a better graph ?
your search to the scientific literature rather than political
entertainment websites.
Remember the _Readers Guide to Periodic Literature_?

in a misleading way.
People haven't survived through climate
changes for 485 million years.
They've survived through them for about 2 million, at the
outside. Agricultural society has managed the survive the
climate changes of just the last 10,000.
Here's a chart on a more useful scale: https://xkcd.com/1732/
(check the mouseover :-)
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.
We need to fix the climate to what's good for humans. What it was
5 million years ago is irrelevant.

Climate has always varied. And: Most species have gone extinct.
We need to change that.It depends. Could be that the return on investment by letting some small insignificant species Z, in rainforest Y, go extinct is totally worth it. Yes, I'm giving an exagerated example, to illustrate the point that keeping a species artificially alive does not have some inherent, inviolable value. It needs to be measured, as with everything. What is pro and what is contra.
I don't want humans to go extinct, which means we have to keepClimate change will not cause humans to go extinct. Not even close. I think you should worry more about pandemics, nuclear war and identity politics. Each of those 3 are more likely to make the human species go extinct than climate change.
climate within the range we know we can handle.
Its not just a matter of whether we, personally, are comfortable.We've never had as much food and as little famine on the planet than we have today. So looking at the trends, we're actually doing better and better.
Our food species also need to be sustained, and they're a lot
more sensitive than we are.
