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

and not man made - temperature rise of about 0.5 degrees C per century could continue for
another 200 years. Therefore, the best data available leads to an extrapolated value of about
1 foot of rise during the next two centuries," Robinson wrote to EPW on September 23,
2007. "There is no scientific basis upon which to guess that the rise will be less or will be
more than this value. Such a long extrapolation over two centuries is likely to be
significantly in error - but it is the only extrapolation that can be made with current data.
There may be no sea level rise at all. No one knows," he added. (LINK)
Canadian Geologist Albert F. Jacobs, co-founder of the group Friends of Science,
critiqued the Associated Press for hyping climate fears in 2007. "Basic to the IPCC case for
sea level rise and for the alarmists' hype is the hypothesis that increasing levels of carbon
dioxide will cause increasing amounts of global warming. It should be stressed that this
assumption of truth is no more than a hypothesis, which is increasingly being attacked and
on which any meaningful discussion has been thwarted by the IPCC's political masters,"
Jacobs wrote to EPW on September 23, 2007. "As far as CO2 is concerned, basic physics
has always been clear about the limitations of higher concentrations of gas to absorb
equivalent amounts of heat radiation. ‗Doubling of CO2' does none of the things the IPCC's
computer says it does. And that's all separate from the fact that water vapour is a much
greater ‗greenhouse' driver than carbon dioxide in any case," Jacobs added. (LINK)
Meteorologist Chuck F. Wiese, the president of the Portland Oregon based
Weatherwise, Inc., lambasted "fancy computer models that can be manipulated" and "are
absolutely incorrect and fraudulent." Wiese called computer model predictions of climate
doom a "bunch of baloney." "The physics of this is in support of anyone who is a skeptic.
As I have said, C02 is of secondary importance; anything that we did to reduce C02
emissions is going to make no change in my opinion that you could really measure in the
climate response at all, because other things are going on that just overpower the small
contribution you get from C02, it does not make a dog's bit of difference," Wiese said in a
January 18, 2007 radio interview. (LINK)
American Enterprise Institute's (AEI) Joel Schwartz, who holds a master's degree in
planetary science from the California Institute of Technology, touted a significant 2007
peer-reviewed study as "overturning the UN IPCC 'consensus' in one fell swoop." "New
research from Stephen Schwartz of Brookhaven National Lab concludes that the Earth's
climate is only about one-third as sensitive to carbon dioxide as the IPCC
(Intergovernmental Panel on Climate Change) assumes," wrote AEI's Schwartz in an
August 17, 2007 blog post. (LINK) The study's "result is 63% lower than the IPCC's
estimate of 3 degrees C for a doubling of CO2 (2.0-4.5 degrees C, 2SD range). Right now
we're about 41% above the estimated pre-industrial CO2 level of 270 ppm. At the current
rate of increase of about 0.55% per year, CO2 will double around 2070. Based on
Schwartz's results, we should expect about a 0.6 degrees C additional increase in
temperature between now and 2070 due to this additional CO2. That doesn't seem
particularly alarming," AEI's Schwartz explained. "In other words, there's hardly any
additional warming ‗in the pipeline' from previous greenhouse gas emissions. This is in
contrast to the IPCC, which predicts that the Earth's average temperature will rise an
additional 0.6 degrees C during the 21st Century even if greenhouse gas concentrations
stopped increasing," he added. "Along with dozens of other studies in the scientific
literature, [this] new study belies Al Gore's claim that there is no legitimate scholarly
