The Oregon Petition
The Oregon Petition is a petition of 31,000 scientists who assert skepticism over climate change. It was written in response to the Kyoto Protocols to show that a scientific consensus on climate change does not exist. Art Robinson, founder of The Oregon Institute of Science and Medicine, is the senior author of the petition. As of 2015, the petition has 31,487 signers, including 9,029 PhDs.
We urge the United States government to reject the global warming agreement that was written in Kyoto, Japan in December, 1997, and any other similar proposals. The proposed limits on greenhouse gases would harm the environment, hinder the advance of science and technology, and damage the health and welfare of mankind. There is no convincing scientific evidence that human release of carbon dioxide, methane, or other greenhouse gasses is causing or will, in the foreseeable future, cause catastrophic heating of the Earth's atmosphere and disruption of the Earth's climate. Moreover, there is substantial scientific evidence that increases in atmospheric carbon dioxide produce many beneficial effects upon the natural plant and animal environments of the Earth.
