Norman Rogers is a policy advisor to The Heartland Institute, speaking and sometimes writing on the topic of global warming. He divides his time between residences in Chicago and Florida. Rogers has held a variety of engineering and computer programming jobs with IBM, Hewlett Packard and other companies. In 1980 he started a high tech company in Santa Clara, California that gradually grew into a much larger company and was sold in 2005. Currently he is developing a new business, ScienceLights.com, that will manufacture easy-to-install home fluorescent lighting. Rogers took up the study of global warming as a retirement project. His position, expressed in a 2009 essay titled "Global Warming Blues" available at AmericanThinker.com, is that computer climate models are vastly overrated and their predictions are so speculative as to be meaningless. He also believes that some moderate warning would produce benefits as well as harms, and that reducing emissions without the participation of China and India would be pointless. Rogers received a bachelor of arts degree in physics at the University of California at Berkeley and a master of science degree in physics from the University of Hawaii, where he also completed coursework for a Ph.D. in physics. For two years he was director of operations at Zero Population Growth, a fairly radical environmental advocacy group led by Stanford Professor Paul Ehrlich. He is currently a member of the American Geophysical Union and the American Meteorological Society.
