Well, if the Earth really gets that bad (e.g. the entire surface is all water, no land; or extremely destructive weather events; or too dark because sunlight can't reach our surface), it might actually be easier to set up self-contained (bubble) cities on another planet than on earth itself.
But if you're talking about terraforming, then if we could terraform another planet we could probably re-terraform earth itself.

The issue with climate change is that higher temperature means more energy and thus more extreme climate. Plus there's desertification but that is, to some extent, a different issue.
- isostatic 10y agoWe'd still have protection from cosmic radiation. Antarctica is far more livable than anywhere else off earth, but I don't see us living there in a self-sustained fashion. Space exploration and colonisation is important, but it's not an answer for the Earth's problems. It may lead to new technologies that will help on earth though - not least the requirement for sustainability.
