In this part of the country we have pretty good weather records that go back about 150 years. If the earth were only 15,000 years old, that would be a 1% sample. Pretty small sample to try to establish what is "normal."
Scientists tell us there have been several ice ages over thousands of years with periods of warming between. I don't suppose our ancestors were sitting around a campfire banging their clubs on the ground asking, "How have we caused this?"
