Climate Change Reconsidered II: Physical Science
Climate Change Reconsidered II: Physical Science is an independent, comprehensive, and authoritative report on the current state of climate science published in October 2013. It is the fourth in a series of scholarly reports produced by the Nongovernmental International Panel on Climate Change (NIPCC), an international network of climate scientists sponsored by three nonprofit organizations: the Center for the Study of Carbon Dioxide and Global Change, the Science and Environmental Policy Project (SEPP), and The Heartland Institute.
The Summary for Policymakers was written in collaboration with the lead authors and approved by them. Because it is aimed at a larger popular audience than the book, it adds a discussion of the scientific method and the precautionary principle, a brief summary and critical analysis of each of the IPCC's main lines of argument, and a brief set of recommendations for policymakers. We also recommend you review the separate Executive Summary.
Previous volumes in the Climate Change Reconsidered series were published in 2008, 2009, and 2011. Those volumes along with separate executive summaries for the second and third reports are available for free online on this site. Find them on the right sidebar.
Whereas the reports of the United Nations’ Intergovernmental Panel on Climate Change (IPCC) warn of a dangerous human effect on climate, NIPCC concludes the human effect is likely to be small relative to natural variability, and whatever small warming is likely to occur will produce benefits as well as costs.
Climate Change Reconsidered II consists of three parts: Part One titled Physical Science, Part Two titled Biological Impacts, and Part Three titled Benefits and Costs of Fossil Fuels. Part One was released on September 17-18, 2013 in Chicago, Illinois USA. Additional release events took place the following weeks in Washington, DC, New York, Florida, St. Louis, England, Germany, Holland, and California. Part Two was released on April 9, 2014. Part Three will be released chapter-by-chapter on this site in November and December 2015.
