In 2008, a group of more than 31,000 scientists signed a petition dissenting from the position of the United Nations' Intergovernmental Panel on Climate Change (IPCC) that man-made CO2 emissions are destroying our planet. More than 9,000 of them have Ph.D. degrees in fields like atmospheric science, climatology, earth science, and environmental science. That's fifteen times more Ph.D. scientists than are involved in the IPCC campaign.
One of the group's leaders, the late Professor Frederick Seitz, said:
The United States is very close to adopting an international agreement that would ration the use of energy and of technologies that depend upon coal, oil, and natural gas and some other organic compounds. ... This treaty is, in our opinion, based upon flawed ideas. Research data on climate change do not show that human use of hydrocarbons is harmful. To the contrary, there is good evidence that increased atmospheric carbon dioxide is environmentally helpful.
Seitz was a first-rate scientist who served as president of Rockefeller University and president of the U.S. National Academy of Sciences. Seitz was also a recipient of the National Medal of Science. The agreement to which he referred is the Kyoto Protocol.
