I was surprised to learn that scientists in growing numbers have questioned the science of manmade global warming since 1992. More than fifteen years ago, the questioners numbered just 47, though they included some of the most eminent scientists in the world. Since then there have been growing numbers of scientists willing to publicly question global warming science, though they have been attacked for doing so. One hundred and fifty signed the Leipzig Declaration; 425 scientists, including 72 Nobel Prize winners, signed the Heidelberg Appeal (their numbers grew to 4,000); while the Oregon Institute of Science and Medicine's Petition of 2001, led by Dr. Frederick Seitz, past president of the National Academy of Sciences, obtained the signatures of 17,800 scientists.
I wonder if you have heard about these petitions. They do not seem to make the major press, but this weekend they did appear in Canada's National Post, in a column by Lawrence Solomon, who asks a very interesting and important question.
Recently, signatories to the Oregon petition, outraged at the continuing corruption of science, wrote to the Oregon Institute and its director, Arthur Robinson, asking that the petition be brought back. Since then more than 31,000 scientists have signed. Their names will be released today at the National Press Club in Washington.
Prominent British scientists who dispute the Al Gore consensus include Freeman Dyson, a brilliant physicist and peace activist, and David Bellamy, a respected environmentalist and biologist.
Is the latest petition "enough to establish that the science is not settled on global warming?" asks Solomon. We doubt it. Solomon has written a book that describes the campaign of vituperation and intimidation against scientists who question the science behind global warming. I admire their courage.
