What doesn't get enough attention are sea currents. Aside from the atmosphere, they are the key to the climate, and not something we can really control. Changing sea currents in the Atlantic can cause much colder weather in the lower part of the Northern hemisphere, and also cause more extreme weather patterns. Everything is connected, everything influences everything, and the Earth is a closed ecosphere which we're all a part of. Since we have passed the point where things could be reversed, things will just get worse, faster and faster. It's also become obvious not many people care what happens, or rather - they do, but they still don't think it will. Pretty insane...
