This stimulating monograph challenges the 2001 Intergovernmental Panel on Climate Change (IPCC) report that indicates a significant increase in carbon dioxide levels and prescribes worldwide policies for curbing global warming. With an in-depth look at the IPCC report itself, this examination argues that the quality and reliability of the IPCC’s measurements are poor, the system of determining how much weight should be attributed to different influences on the earth’s temperature is faulty, and the validity of evidence derived from computer modeling is questionable. By challenging the IPCC’s methodology and results, this pointed assessment has far-reaching consequences for the effectiveness of policy decisions regarding global warming and rising carbon dioxide levels made by the IPCC and other organizations.
