The
Nongovernmental International Panel on Climate Change (NIPCC) is a
climate change denial advocacy organisation set up by
S. Fred Singer's
Science & Environmental Policy Project, and later supported by the
Heartland Institute lobbying group, in opposition to the assessment reports of the
Intergovernmental Panel on Climate Change (IPCC) on the issue of
global warming.
[1]
The NIPCC presents itself as an "international panel of nongovernment scientists and scholars who have come together to present a comprehensive, authoritative, and realistic assessment of the science and economics of global warming". Because it is not a government agency, and because its members are predisposed to dispute that
climate change is caused by human
greenhouse gas emissions, NIPCC claims to offer an independent “second opinion” of the evidence reviewed – or not reviewed – by the IPCC.
[2] The scientific validity of the claims made by the NIPCC report have been heavily criticized,
[3][4] as has the methodology of their reports and the lack of expertise of many of their authors.
