Siegfried Frederick Singer (born September 27, 1924) is an atmospheric physicist. In 1959 he was selected as one of "Ten Outstanding Young Men of the Nation," by the U.S. Junior Chamber of Commerce. He was involved in designing on of the first instruments used in a satellite to measure ozone [1].

He is President of The Science & Environmental Policy Project, a non-profit policy research group disputing climate change and ozone depletion theory, which he founded in 1990. He is also Distinguished Research Professor at George Mason University and Professor Emeritus of environmental science at the University of Virginia, and an Adjunct Fellow of "Frontiers of Freedom" [2].

He is known for his skeptical views about greenhouse gas induced global warming. Although he considers the observed increase in CO2 and CFCs to be anthropogenic, he disagrees with IPCC conclusions about how much warming is to be expected. He is also skeptic on the connection between CFCs, ozone depletion, ultraviolet radiation and skin cancer.

He holds a PhD in physics and is a fellow of the American Physical Society. The famous theoretical physicist John Archibald Wheeler was Singer's advisor.
