mP: "So why havent governments done anything major to combat this menace ?"
Geh i dunno. Perhaps because the voters are for some part dumbasses who does not understand the issue very well, you know, the kind of types who think dumb things like: "fat people feel more heat" pass as an intelligent observation, or does not have the mental stamina to read the first line of an article they quote before blurbing out a question which was answered in that very first line?
Or perhaps because its a very hard issue to do anything about internationally when an agreementt have to be struck between parties like china, usa, eu, russia and all they agree about is the other parties should do more than themselves?
What really boggles my mind is how, at the same time, the "politicians" can all do nothing and be involved in some evil conspiratorial cap-and-trade scheme
