Ohh and everyone else… The very short form is that the Permian extinction killed off over 90% of all species on Earth.

That is what happens when you cross enough tipping points, and we are marching towards such tipping points right this instant.

In other words, if nothing is done to change our emissions patterns, it is actually possible as in a credible, non zero chance, that we are condemning ourselves and many other to extinction some 2-300 years down the line.
