From Canada Free Press:
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.”
Carpe Diem has a link to the actual report, but I was unable to access it – it’ll be interesting to see just how our global warming zealots deal with this report.
It has long been my opinion that if the earth is, indeed, in a long term warming trend, then there is pretty much nothing we can do to stop it. If it wasn’t caused by us, then that is just a natural position to hold – but even if it were caused by us, then it took more than a century to put into effect, and it would likely take longer than that to stop and then reverse the effects…meaning, of course, that there’s no point in trying to reverse it (though it still is wise to reduce pollution on general principle), and we might as well adapt to it. In addition to this, I hold that the doomsday predictions of the global warming zealots are just absurd – they have no idea what would really happen if the world warmed up by a few degrees over the next 100 years. Scare stories based on guesses just don’t impress me much.
