Gerald Marsh, retired nuclear physicist from Argonne National Laboratory presents his views on the science of Man-Made Global Warming and impact on economy and energy security.
Gerald Marsh - Contrary to the conventional wisdom of the day, the real danger facing humanity is not global warming, but more likely the coming of a new Ice Age.
Gerald Marsh - According to the 2007 IPCC Summary for Policymakers, essentially all of the anthropogenic radiative forcing since 1750 is due to the increase in carbon dioxide concentration. This means that if the sun is responsible for 36-50% of the temperature rise since 1900, the IPCC is using too large a value for its coefficient relating radiative forcing to changes in carbon dioxide concentration. This is important because a smaller value of α reduces the sensitivity of the earth’s climate to increases in carbon dioxide concentrations—a result that has significant policy implications.
Gerald Marsh - The purpose of this critique is to help the reader determine whether our understanding of the earth’s climate is adequate to predict the long-term effects of carbon dioxide emissions from the continued burning of fossil fuels, to permit informed public policy decisions.
Climate Change 2001: The Scientific Basis, the Contribution of Working Group I to the Third Assessment Report of the Intergovernmental Panel on Climate Change, the volume is remarkable for many reasons, not least of which is that it has essentially eliminated the Medieval Warm Period of the 11th to 14th centuries and the Little Ice age of the 17th to 19th centuries.
