Investor's Business Daily cites Climate Depot: For his questioning of climate orthodoxy, Rossiter, an adjunct professor at American University, was sacked via email from his position with the Institute for Policy Studies...Rossiter doesn't accept these claims, noting "the computer models simply built in the assumption that fossil fuels are the culprit when temperatures rise, even though a similar warming took place from 1900 to 1940, before fossil fuels could have caused it." He also questions the logic behind imposing calamitous human suffering for improvements that are at best infinitesimal for global temperatures. "Computer models used by the U.N. Intergovernmental Panel on Climate Change to determine the cause of the six-tenths of one degree Fahrenheit rise in global temperature from 1980 to 2000 could not statistically separate fossil-fueled and natural trends," he writes. Rossiter has also ripped President Obama's climate claims. In a 2013 blog post, he said the president "has long been delusional on this issue, speaking of a coming catastrophe and seeing himself as King Canute, stopping the rise in sea level."
