This is sort of like the evolution debate. Evolution is a fact. Natural selection is a theory that explains those facts. Human-induced climate change is a fact. We pump billions of tons of crap into the air every year. It can’t have no effect. Some would like to believe that the Earth can compensate somehow. I agree, that would be nice. It doesn’t change the very important mission that human beings have in front of us. Our population and technology have advanced to a point that the Earth is no longer big enough to use as a garbage can.
The first step is to realize you have a problem.
