Global warming existsIf you go back as far to the ancient Ice Age.
However, the idea that the planet is somehow being subjected to a radical change in climate from man made activity is ridiculous, unfounded, unprovable and flies in the face of the traditional rules of scientific hypotheseis and theory.
Its disgusting to grunt” level scientists (like myself) that so many high profile scientists would sell-out and embrace this climate change garbage.
Good call Sgt Schultze!
A more honest and accurate case could be made if we were to take our original models back to day 1 in Earth's existence. I think the understanding is that the planet then was inhospitably hot and filthy. It was certainly much hotter and less livable than where we are today. A trendline based at that point would show a planet that is cooling and becoming cleaner.
