The ignorant Greenie global warming doomsterists only go back a few thousand years, or maybe up to 680,000 years, which they think of, with their limited perspective, as being a long time. That's a good graph which shows the big picture. Good times were when Earth was over 1000 ppm of CO2.
Notice the two big things = the carboniferous stripping of the atmosphere and burial of carbon in coal, limestone, oil, gas, shale, tars and the resulting ice age and the recent era in which we are stuck which is also ice age, with a temporary reprieve just now.
Gaia is a suicidal maniac, which is trying to freeze to death while stripping the ecosphere of carbon and burying it permanently in stupendously vast graves. The silly Greens think Gaia is happily "in balance". It is not and never was.
We are in great danger of Earth turning to a snow-ball. If they think sea levels up a metre or two and some more heat in some places is a bad thing, they should think about what a frozen Earth would be like to live on. Not just frozen like the last glaciation but frozen to the equator with maybe a bit of chilly water peeking out in a couple of places in equatorial Pacific Ocean and Atlantic Ocean, where "polar" bears will eke out an existence for a little while. Remnant human competition will see them off pretty quickly if they even manage to follow the edge of the ice.
1000 ppm should be the minimum CO2. That's a difficult goal to reach. After a century of effort, we have only reached 380ppm. We could be over-run by a glaciation any time.
