About the NIPCC

The Nongovernmental International Panel on Climate Change (NIPCC) is what its name suggests: an international panel of nongovernment scientists and scholars who have come together to understand the causes and consequences of climate change. Because we are not predisposed to believe climate change is caused by human greenhouse gas emissions, we are able to look at evidence the Intergovernmental Panel on Climate Change (IPCC) ignores. Because we do not work for any governments, we are not biased toward the assumption that greater government activity is necessary.

The NIPCC traces its roots to a meeting in Milan in 2003 organized by the Science and Environmental Policy Project (SEPP), a nonprofit research and education organization based in Arlington, Virginia. SEPP, in turn, was founded in 1990 by Dr. S. Fred Singer, an atmospheric physicist, and incorporated in 1992 following Dr. Singer's retirement from the University of Virginia.

Originally called "Team B," NIPCC was created to provide an independent "second opinion" on the topics addressed by the initial drafts of the IPCC's Fourth Assessment Report. When the Summary for Policymakers of that report was released in February 2007, "Team B" met again, this time in Vienna, changed its name to NIPCC, and started work on what would become this report. A score of independent scientists from around the world began to share their research and ideas with Dr. Singer, as they continue to do. Some of these scientists have asked not to be named in NIPCC reports for fear of losing research grants and being blacklisted by professional journals.

In April 2008, The Heartland Institute published Dr. Singer's first critique of the IPCC's Fourth Assessment Report. That publication, titled Nature, Not Human Activity, Rules the Climate, listed 24 contributors from 14 countries and included a foreword by Dr. Frederick Seitz, one of the world's most renowned scientists. (Dr. Seitz passed away on March 2, 2008.) It was subtitled "Summary for Policymakers of the Report of the Nongovernmental International Panel on Climate Change."

Work on the full NIPCC report continued, with more scientists joining the research team and positive feedback coming from scholars around the world. The report got a major boost when Dr. Craig Idso, chairman of the Center for the Study of Carbon Dioxide and Global Change, agreed to combine the extensive collection of reviews of scientific research he helped write and post on his organization's Web site with the work Dr. Singer had started.

In June 2009, the first full NIPCC report was published by The Heartland Institute. It is titled Climate Change Reconsidered: The 2009 Report of the Nongovernmental International Panel on Climate Change (NIPCC). The new report, some 880 pages in length, is the most comprehensive critique of the IPCC's positions ever published. It lists 35 contributors and reviewers from 14 countries and presents in an appendix the names of 31,478 American scientists who have signed a petition saying "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."

The NIPCC continues its work today, regularly reviewing the peer-reviewed scientific literature and archiving those reviews on this website. And, it will continue to produce major assessment reports to help inform policy makers and the public at large concerning the expected impacts (and non-impacts) of rising atmospheric carbon dioxide on the biosphere.

NOTICE: As of September 1, 2014, this website will no longer post weekly summaries of new scientific research articles. Such postings, and more, can be found at the CO2 Science website,, which is managed by the Center for the Study of Carbon Dioxide and Global Change, one of the three main supporting organizations of the NIPCC.

We encourage you to visit CO2 Science regularly, as new material is posted there nearly every weekday. You can also subscribe to receive a free weekly email that will alert you of newly posted website material. Or, follow CO2 Science on Twitter to receive rapid notification of new content.

Thank you for visiting and for your interest in this important debate.
