Previous climate changes happened over tens of thousands of years. This one is happening in decades.
It's the speed, not the magnitude that matters. Change faster than evolution and migration will destroy ecosystems.
- alt227 9mo agoYeah, I wonder how fast Chicxulub affected the earth when the majority of large dinosaurs were wiped out. The earth survived and evolved another set of new large animal masters. The beauty and diversity of nature we see around us has all evolved after several extinction level events which have all very rapidly killed ecosystems and changed the earths climate. It will do the same again after all humans are gone. This is the outcome I am hoping comes sooner rather than later.
