Ayn Rand Institute Press Release

The Enemies of Energy
December 10, 2007

Irvine, CA--King Ranch and the environmentalist coalition Coastal Habitat Alliance are suing Texas Land Commissioner Jerry Patterson in an attempt to stop the creation of a windmill farm along the Gulf Coast in Kenedy County. According to the suit, the wind farm could kill migrating birds and damage the bay.

"From fossil fuels to nuclear energy, environmentalists have consistently opposed the development and use of every practical energy source," said Dr. Keith Lockitch, resident fellow at the Ayn Rand Institute. "For decades they have been urging us to find viable sources of 'alternative energy.' Yet now that wind farms have become just such a source, environmentalists object to them as well, making it unmistakably clear that enabling us to efficiently power our industrial society was never their goal.

"All of the wealth Americans enjoy--the computers, the cars, the homes, the food, the medicines that enable us to live longer, healthier, happier lives--depends on large-scale creation of energy. To demand that we scale back on energy production and willingly accept crippling privations in the name of 'conservation,' is to demand that we return to pre-industrial squalor.

"Might that be what environmentalists really want?"


Climate warming is natural, not human caused, says new study
International Journal of Climatology of the Royal Meteorological Society [DOI: 10.1002/joc.1651] (December 2007)

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."
