Climate change is a big potential ecological disaster - for us. Earth has had periods of much hotter temperatures than climate change is likely to induce. During the early Carboniferous period, the average global temperature was almost 10 degrees Celsius higher than today. It would take a long time to turn Earth into Venus, or even something similar to the Carboniferous

Yes, in millions of years life may come back if we don’t trigger runaway greenhouse effects, but that’s still a lot of life destroyed.
- mikekchar 7y agoIt's not clear to me that we understand the conditions under which the earth was much hotter, or specifically what conditions resulted in cooler periods. There was a article a few days ago discussing the theory that one of the ice ages was caused by inter-planetary dust. This is an honest (and unpolitical) question: how much do we know about these past climate changes are what caused them?
