S. Fred Singer, professor emeritus at the University of Virginia and director of the Science and Environmental Policy Project. Gerald E. Marsh, a retired physicist from Argonne National Laboratory - Many people believe that wind and solar energy are essential for replacing nonrenewable fossil fuels. They also believe that wind and solar are unique in providing energy that’s carbon-free and inexhaustible. A closer look shows that such beliefs are based on illusions and wishful thinking.
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.
