I really don't buy into the climate change 'movement' but I do know that we are pissing in our own corn flakes. I think Canada has more fresh water than any other country, yet at any given time there are over 1000 communities on 'boil water alerts' - meaning their municipalities can't even provide them with water that is safe for drinking. Some of the most massive rivers on the planet have become veritable sewage canals, the rain forest is disappearing, and the air in some major North American cities can occasionally incapacitate the elderly or infirm.
So regardless of how one mucks about with the equations of climate change, the human species has turned into the worst epidemic this ever to plague this planet. I think we would do well to change our ways before that is our legacy.
He's just stating his opinion. He is stating facts, but he's ignoring or left other facts that dispute or don't support his claim. Whether climate change is happening or not, I'm of the opinion that we should strive for cleaner environment. CO2 is an naturally occurring gas, but the core samples from the ice show the current levels to be extremely high. The oceans pH value is lowering, becoming more acidic. There is a very real threat that the lower pH level could disrupt the oceans food chain. Also, weather patterns could change and cause climates to change drastically.
