Small Coalition of US Scientists Still Believe Global Warming Not Man-Made

From the beginning of the second paragraph onwards, my very opinionated voice will disappear from this article. I do not want to put any emphasis or spin on what I’m going to write. These are facts and their opinions, and they are what they are - incontrovertible in and of themselves.

In a world that has all but determined global warming is our fault, there are a few hold outs. A small group of US scientists are among them, who point to large pools of data and evidence that do not support such a conclusion.

To these scientists, experts in their field, global warming is nothing but a natural phenomenon. The International Journal of Climatology, a publication of Britain’s Royal Meteorological Society, will soon see a paper written by these scientists. It will endeavor to portray what they believe to be the real story.

“The observed pattern of warming, comparing surface and atmospheric temperature trends, doesn’t show the characteristic fingerprint associated with greenhouse warming,” wrote lead author David Douglas, a climate expert from the University of Rochester, in New York (state). “The inescapable conclusion is that human contribution is not significant and that observed increases in carbon dioxide and other greenhouse gases make only a negligible contribution to climate warming.”

According to another author of the paper, John Christi from the University of Alabama, satellite data “and independent balloon data agree that the atmospheric warming trends do not exceed those of the surface,” while greenhouse models “demand that atmospheric trend values be two to three times greater.”

The authors add that the data from their satellite observations “suggest that greenhouse models ignore negative feedback produced by clouds and by water vapor, that diminish the warming effects” of human co2 emissions.

Fred Singer, third author of the paper and a climatologist at the University of Virginia, looks to the evidence to see that the global warming “trend is simply part of a natural cycle of climate warming and cooling that has been seen in ice cores, deep sea sediments and stalagmites . . . and published in hundreds of papers in peer reviewed journals.”

The authors of the paper admit that they do not know how these cyclical climate patterns take place, but suggest that they “are most likely caused by variations in the solar wind and associated magnetic fields that affect the flux of cosmic rays incident on cloudiness, and thereby control the amount of sunlight reaching the earth’s surface and thus the climate.”

Singer also points to other evidence, further putting a murky haze over global warming. Between 1900 and 1940 temperatures rose, obviously well before humanity began to burn the large amounts of hydrocarbons that it does today. But then during the next 35 years these emissions decreased, as oil and coal use increased.

The paper sheds light on many of the uncertainties in the case for a man-made global warming. And the only way to effectively do this is to have based their conclusions in fact, exactly what they have done. Whether other scientists, more deeply ingrained in the man-made opinion, will knock them down is just reason to wait and see.
