For ten years or more, professor David Deming has taught a course in environmental geology at the University of Oklahoma.
Professor Deming is well-known to be a global-warming skeptic. In 2006, he testified before the US Senate:
“In 1995, I published a short paper in the academic journal Science. In that study, I reviewed how borehole temperature data recorded a warming of about one degree Celsius in North America over the last 100 to 150 years. The week the article appeared, I was contacted by a reporter for National Public Radio. He offered to interview me, but only if I would state that the warming was due to human activity. When I refused to do so, he hung up on me.
I had another interesting experience around the time my paper in Science was published. I received an astonishing email from a major researcher in the area of climate change. He said, “We have to get rid of the Medieval Warm Period.”
“There is an overwhelming bias today in the media regarding the issue of global warming. In the past two years, this bias has bloomed into an irrational hysteria. "
This hysteria is still apparent, even as global temperatures show a pronounced cooling trend. If CO2 is the prime forcer, rather than being insignificant, then there should be evidence.
