Hundreds Sign Climate Realist Declaration ‘Global Warming’ is not a Global Crisis

Published April 22, 2008

(Ottawa, Canada – April 22, 2008) The International Climate Science Coalition (ICSC) today released the names of over 500 endorsers of the Manhattan Declaration on Climate Change that calls on world leaders to “reject the views expressed by the United Nations Intergovernmental Panel on Climate Change (IPCC) as well as popular, but misguided works such as ‘An Inconvenient Truth.'” All taxes, regulations, and other interventions intended to reduce emissions of carbon dioxide (CO2) should “be abandoned forthwith,” conclude declaration signatories.

Included in the endorser lists are world leading climate scientists, economists, policymakers, engineers, business leaders, medical doctors, as well as other professionals and concerned citizens from two dozen countries. The complete declaration text, endorser lists and international media contacts for expert commentary, may be viewed at

Perhaps most significant among the declaration’s assertions:

  • “[T]here is no convincing evidence that CO2 emissions from modern industrial activity has in the past, is now, or will in the future cause catastrophic climate change.”
  • “[A]ttempts 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. Such policies will markedly diminish future prosperity and so reduce the ability of societies to adapt to inevitable climate change, thereby increasing, not decreasing human suffering.”
  • “Just as the Manhattan Project was key to finally ending the World War II, the Manhattan Declaration on Climate Change may one day be regarded as a critical catalyst that helped end today’s climate hysteria,” said ICSC Science Advisory Board member Professor Bob Carter of James Cook University in Australia. “Protecting the natural world is crucially important, and so environmental policy must be based on our best understanding of science and technology coupled with a realistic appreciation of the relevant economics and policy options. This is not happening in the climate debate.”

ICSC Chair, Professor Tim Patterson of Carleton University in Ottawa, Canada concludes, “Instead of wasting billions restricting emissions of CO2, a vitally important gas on which all life depends, governments must concentrate on solving known environmental problems over which we have influence – air, land and water pollution being obvious examples.”

The ICSC is an association of scientists, economists and energy and policy experts working to promote better public understanding of climate change. ICSC provides an analysis of climate science and policy issues which, being independent of lobby groups and vested political interests, is an alternative to advice from the IPCC. ICSC thereby fosters rational, evidence-based, open discussion about all climate, and climate-related, issues.
