Last year, a week after the Harvard Crimson published a shocking editorial chiding Nobel Laureate Al Gore, Stanford University held a luncheon entitled "Is Global Warming a Myth?"
The Stanford guest speaker was the world-renowned global warming skeptic S. Frederick Singer, a former space scientist and government scientific administrator. Singer, who holds PhD in Physics from Princeton University, was a Special adviser to President Eisenhower on space developments, a professor of Environmental Sciences at the University of Virginia, and co-author of Unstoppable Global Warming: Every 1,500 Years.In this New York Times bestseller, authors Singer and co-author Avery present the compelling concept that global temperatures have been rising mostly or entirely because of a natural cycle. Using historic data from two millennia of recorded history combined with natural physical records, they argue that the 1,500 year natural sunspot magnetic waves cycle that has always controlled the earth's climate remains the driving force in the current warming trend. Man created carbon dioxide has very little effect on the earth's climate.
Since the 1,500 year cycle was discovered in the early 1980's it's general characteristics have been confirmed by measurements in: tree rings (living, preserved and fossilized), pollen, coral, glaciers, boreholes, stalagmites, tree lines, and sea sediments. The most recent cycles have been recorded in human history with forced migrations, starvation, and disease during the cold portion of the cycle and greater population, expanded farm land, greater crop variety, and extra building during the warm portion.The causes of the 1,500 year cycle are not well understood although 600 of them have been identified in the last million years. This permits the authors to be relatively confident that we have been moving into the warm phase of the cycle for the last 150 years. It also suggests that we may have one or two degrees more warming if we are to get to the typical high of the warm phase.Although the warm phase of the cycle has been typically more regular than the cold phase, it does not move steadily to a peak and then fall off, but rather moves abruptly higher at the start of the warm phase followed by highly irregular (but modestly higher) temperatures for hundreds of years.
Singer explained that the recent warming the Earth has experienced is not dangerous and is not something humans could alter. Global warming activists such as Al Gore, Singer believes, are hyping the problem. He said that such activists have not come close to demonstrating that human-generated greenhouse gases are contributing to global warming.
