Carbon dioxide (CO2) is not a pollutant.
New Peer-Reviewed Study Finds ‘Warming is naturally
caused and shows no human influence’

An inconvenient new peer-reviewed study published in
the December 2007 issue of the International Journal
of Climatology.
Climate warming is naturally caused and shows no human
influence:
Climate scientists at the University of Rochester, the
University of Alabama, and the University of Virginia
report that observed patterns of temperature changes
(‘fingerprints’) over the last thirty years are not in
accord with what greenhouse models predict and can
better be explained by natural factors, such as solar
variability. Therefore, climate change is
‘unstoppable’ and cannot be affected or modified by
controlling the emission of greenhouse gases, such as
CO2, as is proposed in current legislation.
These results are in conflict with the conclusions of
the United Nations Intergovernmental Panel on Climate
Change (IPCC) and also with some recent research
publications based on essentially the same data.
However, they are supported by the results of the
US-sponsored Climate Change Science Program (CCSP).
The report is published in the December 2007 issue of
the International Journal of Climatology of the Royal
Meteorological Society [DOI: 10.1002/joc.1651]. The
authors are Prof. David H. Douglass (Univ. of
Rochester), Prof. John R. Christy (Univ. of Alabama),
Benjamin D. Pearson (graduate student), and Prof. S.
Fred Singer (Univ. of Virginia).
The fundamental question is whether the observed
warming is natural or anthropogenic (human-caused).
Lead author David Douglass said: “The observed pattern
of warming, comparing surface and atmospheric
temperature trends, does not show the characteristic
fingerprint associated with greenhouse warming. The
inescapable conclusion is that the human contribution
is not significant and that observed increases in
carbon dioxide and other greenhouse gases make only a
negligible contribution to climate warming.”
Co-author John Christy said: “Satellite data and
independent balloon data agree that atmospheric
warming trends do not exceed those of the surface.
Greenhouse models, on the other hand, demand that
atmospheric trend values be 2-3 times greater. We
have good reason, therefore, to believe that current
climate models greatly overestimate the effects of
greenhouse gases. Satellite observations suggest that
GH models ignore negative feedbacks, produced by
clouds and by water vapor, that diminish the warming
effects of carbon dioxide.”
Co-author S. Fred Singer said: “The current warming
trend is simply part of a natural cycle of climate
warming and cooling that has been seen in ice cores,
deep-sea sediments, stalagmites, etc., and published
in hundreds of papers in peer-reviewed journals. The
mechanism for producing such cyclical climate changes
is still under discussion; but they are most likely
caused by variations in the solar wind and associated
magnetic fields that affect the flux of cosmic rays
incident on the earth’s atmosphere. In turn, such
cosmic rays are believed to influence cloudiness and
thereby control the amount of sunlight reaching the
earth’s surface and thus the climate.” Our research
demonstrates that the ongoing rise of atmospheric CO2
has only a minor influence on climate change. We must
conclude, therefore, that attempts to control CO2
emissions are ineffective and pointless. – but very
costly.
