WASHINGTON DC – Award winning Princeton University Physicist Dr. Will Happer declared man-made global warming fears to be “a house of cards” and a “truly a mad issue.”

“This is truly a mad issue,” Happer told the crowd of several hundred at the global warming skeptic conference in Washington DC on Thursday night. The event was sponsored by the Heartland Institute. Happer has authored more than 200 peer-reviewed scientific studies.

“Carbon dioxide is not a pollutant, nor will it cause catastrophic global warming,” Happer explained to the audience at the The Tenth International Conference on Climate Change (#ICCC10).

“This whole climate scare is a house of cards,” Happer said.

“The social cost of carbon is probably negative. There is no social cost of carbon,” he added. Happer has previously testified to the U.S. Congress.

Earlier in the day, Atmospheric Physicist Dr. Fred Singer told the summit that the effect of CO2 emissions on climate is “negligible, not important” but very beneficial for agriculture.

Also attending the summit was U.S. Senate Environment & Public Works Committee chairman Senator James Inhofe (R-OK). Inhofe advised Pope Francis to stay out of the climate debate.

“Everyone is going to ride the pope now. Isn’t that wonderful,” Inhofe told reporters. “The pope ought to stay with his job, and we’ll stay with ours.”
