""I don't make climate predictions because I don't know what the Sun will do next," says S. Fred Singer, University of Virginia emeritus professor of environmental sciences and founding director of the U.S. Weather Satellite Service. "But analysis of the best data of the past 30 years has convinced me that the human contribution has been insignificant — in spite of the real rise in atmospheric CO2, a greenhouse gas."

These researchers are not alone. They are among a rising tide of scientists who question the so-called "global warming" theory. Some further argue that global cooling merits urgent concern.

"In stark contrast to the often repeated assertion that the science of climate change is 'settled,' significant new peer-reviewed research has cast even more doubt on the hypothesis of dangerous human-caused global warming," 100 prestigious geologists, physicists, meteorologists, and other scientists wrote U.N. Secretary General Ban Ki-Moon last December. They also noted that "today's computer models cannot predict climate. Consistent with this, and despite computer projections of temperature rises, there has been no net global warming since 1998."

In a December 2007 Senate Environment and Public Works Committee minority-staff report, more than 400 scientists — from such respected institutions as Princeton, the National Academy of Sciences, the University of London, and Paris's Pasteur Institute — declared their independence from the global-warming "conventional wisdom."

"Not CO2, but water vapor is the most important greenhouse gas," asserted climatologist Luc Debontridder of Belgium's Royal Meteorological Institute. "It is responsible for at least 75 percent of the greenhouse effect. This is a simple scientific fact, but Al Gore's movie has hyped CO2 so much that nobody seems to take note of it."

"The hypothesis that solar variability, and not human activity, is warming the oceans goes a long way to explain the puzzling idea that the Earth's surface may be warming while the atmosphere is not," explained Dr. David Wojick, co-founder of Carnegie-Mellon University's Department of Engineering and Public Policy. "The public is not well served by this constant drumbeat of false alarms fed by computer models manipulated by advocates."
