Simply looking at the geologic record we see that the northern hemisphere was covered three times with massive glaciers.. Obviously these glaciers are not present today so there must have been both massive global cooling to cause these ice ages and massive global warming to melt these glaciers. Carbon dioxide levels especially from human activity cannot explain these massive global climate changes so there must obviously be some other mechanism. The global warming hoaxers seem to have no explanation for what has happened in the past.
They ignore the past. They pretend the world began in the last 100 years or something. Their is no real science supporting manmade global warming as far as I know.

Typical response: That was different.
