...that we've stumbled on a way not to have a frozen planet.

That's the neat part of this. The possibility of not having to move, if you will, heaven and earth to avoid the disaster of a much warmer or cooler planet. AGW aside, climate will change.

Yes, climate is constantly changing and always has. It's scary to think that according to the ice core data we're very near the peak of this interglacial.
