Sadly political science has trumped the analytical science of global warming. Government funded scientists, environmentalists, Congress, and the mainstream media have all decreed manmade global warming a fact. However scientific observations and models dont support their conclusions.
Ice core and coral reef samples show the earth has cycled from glacial to interglacial warm periods for millions of years, without mankinds intervention. Water vapor constitutes 95% of all greenhouse gasses, but manmade CO2 constituting 0.001% of our atmosphere, is designated the global warming driver. Yet, observations show that global warming usually precedes rather than follows CO2 increases.
What then causes these cycles, if not man? A combination of uncontrollable external factors, such as periodic changes in the suns radiation, eccentricities in the Earths orbit from near circular to elliptical, and changes in the tilt and precession of Earths axis.
Even the IPCCs Climate Change 2007 Summary for Policymakers, released before the actual report was completed, admits, ice core data indicate the average polar temperatures (125,000 years ago) were 3 to 50C higher than present because of differences in the Earths orbit. The report also predicts temperature and sea level rises in the next 100 years of 3.2o F and 7 23 inches, far below previous estimates.
Phony hockey stick graphs emphasizing recent abnormal global temperature rises by deleting medieval warming and mini ice ages and computer climate models failing to predict observed global temperatures and sea level rises when back tested, only politicize and detract from legitimate analytical climate change science.
