Than 1000 International Scientists Dissent Over Man-Made Global ...

Climate researcher Dr. Craig Loehle, formerly of the Department of Energy
Laboratories and currently with the National Council for Air and Stream
Improvements, who has published more than 100 peer-reviewed scientific papers,
attended the skeptical 2008 International Conference on Climate Change in New
York City in March 2008. ―The 2000-year [temperature] trend is not flat, so a warming
period is not unprecedented,‖ Loehle said during the skeptical conference in March 2008.
―The 1500-year [temperature] cycle as proposed by [Atmospheric physicist Fred] Singer
and [Dennis] Avery is consistent with Loehle climate reconstruction,‖ Loehle explained.
―The 1500-year cycle implies that recent warming is part of natural trend,‖ he added.

Environment that found the Medieval Warm Period to be "0.3C warmer than the 20th
century." The study was titled ―A 2000-year global temperature reconstruction based on
non-treering proxies." (LINK) & (LINK)
German Meteorologist Dr. Gerd-Rainer Weber, a Consulting Meteorologist, attended
the skeptical 2008 International Conference on Climate Change in New York City in
March. ―Most of the extremist views about climate change have little or no scientific basis.
The rational basis for extremist views about global warming may be a desire to push for
political action on global warming,‖ Weber said during the conference. (LINK) Weber also
endorsed the Manhattan Declaration on Climate Change, sponsored by the International
Climate Science Coalition (ICSC) in 2008. The declaration reads in part, ―There is no
convincing evidence that CO2 emissions from modern industrial activity has in the past, is
now, or will in the future cause catastrophic climate change.‖

Professor of Ecology and Evolutionary Biology Dr. W. M. Schaffer, Ph. D., of the
University of Arizona - Tucson, past member of the American Association for the
Advancement of Science, who has authored more than 80 scientific publications and
authored the paper “Human Population and Carbon Dioxide,” dissented in 2008. ―My
principal objections to the theory of anthropogenic warming are as follows: 1) I am
mistrustful of ‗all but the kitchen sink‘ models that, by virtue of their complexity, cannot be
analyzed mathematically. When we place our trust in such models, what too often results
is the replacement of a poorly understood physical (chemical, biological) system by a
model that is similarly opaque,‖ Schaffer told EPW on December 19, 2008. ―2) I am
troubled by the application of essentially linear thinking to what is arguably the ‗mother of
all nonlinear dynamical systems‘ - i.e., the climate. 3) I believe it likely that "natural
climate cycles" are the fingerprints of chaotic behavior that is inherently unpredictable in
the long-term. As reviewed in a forthcoming article (Schaffer, in prep), these cycles are
"dense" on chaotic attractors and have the stability properties of saddles. Evolving chaotic
trajectories successively shadow first one cycle, then another. The result is a sequence of
qualitatively different behaviors - what climatologists call "regime shift" - independent of
extrinsic influences. Tsonis and his associates discuss this phenomenon in terms of network
theory and ‗synchronized chaos,‘ but these embellishments are not necessary. To be chaotic
