[3] All versions of the declaration, which asserts that there is no scientific consensus about the importance of global warming and opposes the recommendations of the Kyoto Protocol, were penned by Fred Singer's Science and Environmental Policy Project (SEPP).
Today, the declaration is regarded as disinformation campaign, exercised by the climate change denial movement using the fake-expert-strategy, to cast doubt on the scientific consensus about global warming.
[5][6][7] The 1995 declaration asserts: "There does not exist today a general scientific consensus about the importance of greenhouse warming from rising levels of carbon dioxide.
The latter statement was broadly accurate at the time, but with additional data and correction of errors, all analyses of satellite temperature measurements now show statistically significant warming.
In an article on 29 July 1996, he revealed that many signers, including Chauncey Starr, Robert Balling, and Patrick Michaels, have received funding from the oil industry, while others had no scientific training or could not be identified.
[9] In any case, it is difficult to accurately evaluate the list of signatures of the 1995 declaration, as the SEPP website provides no additional details about them except for their university, if they are professors.
[2] This version included the claim: "In fact, many climate specialists now agree that actual observations from weather satellites show no global warming whatsoever".
It has been cited by Fred Singer in editorial columns appearing in hundreds of websites and major publications, including The Wall Street Journal, Miami Herald, The Detroit News, Chicago Tribune, The Plain Dealer, Memphis Commercial Appeal, The Seattle Times, and the Orange County Register.
Jeff Jacoby, a columnist with The Boston Globe, described the signers of the Leipzig Declaration as "climate scientists" that "include prominent scholars."
Both the Leipzig Declaration and Frederick Seitz's Oregon Petition have been quoted as authoritative sources during deliberations in the U.S. Senate and House of Representatives.
