There is global warming true. It is not specific to human activities though. The effect humans have on global warming is miniscule at most. The earth climate has always been changing for ever. There were tropical conditions at both poles at one time. Most of the global warming brouhaha is people like Al Gore trying to make a huge profit over the scare. There was continental drift all kinds of changes on earth. Adapt or perish ! Don’t fall for the idiot warmer people’s garbage. Yes the poles might melt, but you can’t stop it . Humans can’t stop it. It is going to happen even if there were no human activity .
