Consensus Shattered As Major Scientific Study Says Global Warming Is Natural
Attempts to reduce CO2 emissions "pointless" as sun is cited as climate change culprit
The so-called scientific consensus that global warming is man-made has been shattered with the release of a major new study backed by three universities which concludes that climate change over the past thirty years is explained by natural factors and that attempts to reduce carbon dioxide emissions are irrelevant.
Climate scientists at the University of Rochester, the University of Alabama, and the University of Virginia report that temperature fluctuations over the past three decades are not consistent with greenhouse model predictions and more closely correlate with solar activity.
The report dismisses attempts to reverse global warming by reducing carbon emissions as ineffective and pointless.
“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," said lead author David H. Douglass.
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."
