Scientist fired by Al Gore was told, "science will not intrude on public policy".

Noted energy expert and Princeton physicist Dr. Will Happer has sharply criticized global warming alarmism. Happer, author of over 200 scientific papers and a past director of energy research at the Department of Energy, called fears over global warming "mistaken".

"I have spent a long research career studying physics that is closely related to the greenhouse effect", said Happer. "Fears about man-made global warming are unwarranted and are not based on good science."

Dr. Happer views climate change as a predominately natural process. "The earth's climate is changing now, as it always has. There is no evidence that the changes differ in any qualitative way from those of the past."

In 1991, Happer was appointed director of energy research for the US Department of Energy. In 1993, he testified before Congress that the scientific data didn't support widespread fears about the dangers of the ozone hole and global warming, remarks that caused then-Vice President Al Gore to fire him. "I was told that science was not going to intrude on public policy", he said. "I did not need the job that badly".

Happer's latest remarks were made yesterday, as he asked to be included in a Senate Environment and Public Works report of scientists disputing global warming alarmism. Happer joins 650 other scientists on the list, many of whom have been interviewed previously by DailyTech.

"Computer models used to generate frightening scenarios from increasing levels of carbon dioxide have scant credibility," Happer concluded.

In response to Happer's remarks, Senator James Inhofe, ranking minority member of the Environment and Public Works Committee, said, "The endless claims of a consensus on man-made global warming grow less and less credible every day".
