Its all the same thing.  We don't change the climate, it changes us.  We'll   either  adapt to it, or not.  Dinosaurs became extinct when they couldn't survive climate change, while  other critters thrived.   Most animals as well as humans will probably do better in a little warmer climate.  Will need to use less energy to stay warm.  The oceans could rise a bit. I don't think it will be noticeable.  Most of our "weather" depends on ocean temperature and water vapor.  2/3 of the earth is water so and there are increasingly more efficient ways of desalinating it for farming and drinking.   Anyway  we would have far more to fear from another ice  age than a couple degrees of warming.  Its not worth the worry.
