The world was once 8C to 14C hotter than it is now (during the Eocene) and it didn't run out of oxygen. In fact, this was the epoch when modern mammals took over the world.

- adrianN 7y agoPrehistoric warm periods didn't happen as fast as what we're doing. If you give nature thousands of generations to adapt to warmer temperatures it's not as big of a deal. If you do it over a hundred years or so, ecosystems have a much harder time to adapt.
- leereeves 7y agoEcosystems can adapt very quickly with a little help. We often see just a few members of an invasive species transplanted into a favorable environment multiply and spread and end up dominating the local ecosystem in far, far less than a hundred years. Let's use that to help ecosystems adapt to climate change.
- adrianN 7y agoWe have pretty poor experience with trying to help ecosystems. Let's hope that we don't have to resort to that.
