2 questions
1. If we stop producing the chemicals and such that cause global warming doesn't that mean that the chemicals etc. are still in our atmosphere?
2. My freind says that Global warming isn't real (I think he is full of s***)
and that the Earth is just on a 20 year cycle where it gets really hot and really cold and the only reason why we weren't worried about it then was because we didn't understand that, is that actually true?
