Greetings from UN Conference in
An inconvenient new
peer-reviewed study published in the December 2007 issue of the
International Journal of Climatology.
Press Release from The Science
& Environmental Policy Project - 10 Dec 07
Climate warming is naturally caused and shows no human influence:
Carbon dioxide (CO2) is not a pollutant.
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 (
), Prof. John R. Christy (
), Benjamin D. Pearson (graduate student), and Prof. S. Fred Singer (
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.
