You almost gotta laugh that almost every argument about climate change excludes the source of life in the universe, the sun. Geological evidence indicates that mile thick glaciers covered most of the Northern Hemisphere as recently as 20,000 years ago. That's a literal drop in the geological bucket of the history of the earth. Cold is the rule of the universe and (thank God) the gigantic nuclear reactor keeps the cold away from the earth for the most part. Isn't it likely that the earth is emerging from an ice age and we should enjoy what we have before it is taken away by a burp in the sun's core? Alas lefties haven't had a nice day since Al Gore invented carbon credits.
