Key Quotes

“The fluctuations in the carbon dioxide concentration appear to track those in temperature to a remarkable degree, but a closer look reveals that the fluctuations generally lag behind those in temperature. Never does a changing carbon dioxide concentration precede that of temperature.”4Harry N.A.

Priem is listed as a “climate expert” who signed the 2008 Manhattan Declaration on Climate Change. The declaration was first presented for consideration at the Heartland Institute’s 2008 International Conference on Climate Change.5CLIMATE EXPERTS WHO SIGNED MANHATTAN DECLARATION,” International Climate Science Coalition. Accessed February, 2012.

The declaration was created by the International Climate Science Coalition (ICSC) and concludes that “attempts by governments to legislate costly regulations on industry and individual citizens to encourage CO2 reduction will slow development while having no appreciable impact on the future trajectory of global climate change.”

Priem a signatory to a 2007 open letter to the UN Secretary General. The letter describes global warming as a natural phenomenon, and claims that the IPCC’s reports are not adequate as justification for climate change policy.6Open Letter to the Secretary-General of the United Nations,” December 13, 2007.

Priem signed a 2006 open letter to Prime Minister Harper that urged the government stall any action on climate policy, suggesting that climate change may have natural causes.

Priem attended a briefing titled “Climate Is not Warming – Has not Warmed in 60 Years” that was co-sponsored by the Cooler Heads Coalition. The briefing supposedly uncovered “a preponderance of evidence against any global warming in the last 60 years.”7CLIMATE IS NOT WARMING – HAS NOT WARMED IN 60 YEARS,” A Briefing by the Science & Environmental Policy Project at COP-6, November 21, 2000. Archived February 15, 2007.

The four-member panel at the briefing consisted of Richard Courtney, Harry N.A. Priem, S. Fred Singer and Gerd-Rainer Weber.

The Cooler Heads Coalition was originally tied to the industry-funded Competitive Enterprise Institute (CEI) and was a project of the National Consumers Coalition. The Consumers Coalition is made up of 23 free market think tanks, including many with oil industry ties such as the Heartland Institute, the Committee For A Constructive Tomorrow (CFACT), the Pacific Research Institute (PRI) and the George C. Marshall Institute.



According to a search of 22,000 academic journals, Priem has published more than 30 research articles in peer-reviewed journals, mainly in the area of geology.
