Al Gore's movie, "An Inconvenient Truth," has met its match: a devastating documentary based on sound science by recording the statements of real climate scientists, says S. Fred Singer, professor emeritus of environmental sciences at the University of Virginia and adjunct scholar at the National Center for Policy Analysis.

The scientific arguments presented in, "The Great Global Warming Swindle," can be stated quite briefly, says Singer:

  • Observations in ice cores show that temperature increases have preceded -- not resulted from -- increases in CO2, by hundreds of years, suggesting that the warming of the oceans is an important source of the rise in atmospheric CO2.
  • As the dominant greenhouse gas, water vapor is far, far more important than CO2, yet not well handled by climate models -- and, in any case, not within our control.
  • Greenhouse models also cannot account for the observed cooling of much of the past century (1940-75), nor for the observed patterns of warming -- what we call the "fingerprints."

The best evidence we have supports natural causes -- part of a natural cycle of climate warming and cooling that's been traced back almost a million years -- leaving little we can do about it.  Climate mitigation schemes will not do any good; they are all irrelevant, useless and wildly expensive, says Singer.

Ultimately, we should not devote our scarce resources to what is essentially a non-problem, says Singer, while ignoring the real problems the world faces: hunger, disease and denial of human rights, in favor of politically fashionable issues.
