Climate has always been changing and will continue to change. What has changed in the past few centuries, and is accelerating, is the rate at which it is changing. It is much faster now than generally in the past but major catastrophes like asteroids, huge volcanic eruptions, and such have created short periods of rapid change and extinction.

Our current problem is that the rate of change exceeds the ability of resources to adapt. Couple that with our general desire to minimize the number of breeders (maximize harvest) we put fewer genes into the mix and the trader ones which might aid in adaptation are less likely to be passed on.

Pogo was right.
