Managing the climate is usually an afterthought in colony building games, if it's included at all. It tends to be a non-issue until the game’s basically over, and its effects are usually underwhelming.
Imagine Earth isn't entirely about the environment. And it needn’t be, given that you're working for a business colonising one of countless worlds. Who cares if you destroy a planet when you can easily skip over to another one? You can do that. You can be pretty rapacious. But I find it more fun to be the oceanic aliens, because they start out with lots of seabase technology, so when your rivals accidentally melt the ice caps you can mostly just laugh at them.
