I'm of the opinion that all of life on Earth evolved over a long period of time to match the more or less steady state environment.

When you go and disturb that steady state by say releasing a million years worth of carbon sequestration over a century, you destabilize the whole thing.

Like a top spinning it all of a sudden collapses. And then humans realize that we were really just along for the ride & do not have a chance to re-stabilize.
