I know I have said this before on here, but when I was in college in the 1970's... yes, I am and old fucker. I lived in a co-op house and there was this guy that was studying environmental science, which was a new thing back then. He explained global warming to me, the whole Co2 thing etc. I listened, and I said, I am sure that we will do something before then. that will address it. He was predicting exactly what has happened. It's not a new idea or a surprise, it's the classic frog in the pan of boiling water. I was wrong, no one has done anything. Or certainly not enough. Listen to the scientists.
