The civilization we've built, globally, is dependent on a certain climate. Certain places are livable and some aren't. Climate change threatens that. Even a few inches of global sea rise threatens millions of people who live in places like Miami or on islands. Many animals as well can only survive under certain climate conditions. So, the Earth will not crack in half, but those of us who live here will have a lot to deal with in the next few decades. Wouldn't it be better to just (or "just") reduce our greenhouse gas emissions?
