The United Nations Intergovernmental Panel on Climate Change (IPCC), the media, and Al Gore repeatedly say that the science of global warming is settled and that only a radical fringe group of corporate-sponsored scientists disagree with the scientific consensus that man is causing global warming. Over $50 billion has been spent to support that believe. However, even as far back as 2003 a survey was conducted among all climate scientists (those actually having climate PhDs and working specifically on climate issues) showed that there was barely a majority, let alone a consensus that man was causing global warming. When the question was asked, "was the scientific debate about climate change over," less than half of the respondents agreed with the question. An equal number disagreed. This is far from a consensus among scientists who can actually speak to the issue.
In 2001 a voluntary petition was sent to all scientists in the United States stating that, among other things, "There is no convincing scientific evidence that human release of carbon dioxide, methane, or other greenhouse gases is causing or will, in the foreseeable future, cause catastrophic heating of the Earth's atmosphere and disruption of the Earth's climate." At that time, 17,000 scientists signed it. When the same petition was sent out in 2008, 31,000 scientists signed it, almost double the number in 2001. Nine thousand of these had PhD's in the physical sciences. This compares to only about 60 (not 2500) that support the IPCC's man-caused theory. More are signing every day. The IPCC's, media's, and Gore's instance that there is a consensus among scientists that the science is settled is completely false, designed to hide the fact that the entire effort is politically, not scientifically, motivated. Every effort is made to silence the dissenters, yet more and more scientists are speaking out because the actual science supporting man-caused warming is non-existent.
