New Report Calls into Question Man-Made Climate Change, by Kevin Mooney, CNSNews.com
New scientific evidence suggests there is a stronger link between solar activity and climate trends on Earth than there is with greenhouse gases, Fred Singer, an atmospheric and space physicist, told CNSNews.com. *** The new data call into question whether scientific evidence shows that global warming is a man-made phenomenon and suggests that natural forces, as opposed to human activity, may drive global climate change.
The report, Nature, Not Human Activity Rules the Climate, has helped open the way for scientists to perform meaningful research in areas that have been largely unexplored and under-emphasized in previous studies, Singer said in the interview. *** For example, he said, there are research efforts now underway that set about to examine the connection between cosmic rays and cloud formation presumed in the sun-climate theory. *** This is the kind of scientific endeavor that has gone missing in government studies that assume human activity predominates over natural influences, Singer continued. Although it was long assumed that the sun was a constant star, one that did not experience any variability (changes) in its irradiance, this has turned out not to be the case. *** To the extent that it does look at solar variability at all, which is limited, the U.N.s International Panel on Climate Change (IPCC) has been disingenuous in its approach to solar variability by virtue of focusing on relatively minute solar cycle changes that overlook cosmic rays, the Singer report suggests. *** There are some significant solar changes involving solar wind, for instance, that have ramifications for Earths climate, which are de-emphasized in the IPPC studies, he said. *** By disregarding or ignoring the very much larger changes of solar ultraviolet or of the solar wind and its magnetic-field effect on cosmic rays and thus on cloud coverage, the IPCC has managed to trivialize the climate effects of solar variability, Singers non-government report states. *** Moreover, there is large separation between the fingerprints of global warming that researchers can actually observe in the atmosphere and the fingerprints predicted by scientific models, Singer said. Any warming that follows from greenhouse gases would appear in the form of warming that increases with altitude, his report explains. *** However, the observations derived from satellites and balloons actually show no increasing warming, but a slight cooling with altitude in the zone of the atmosphere where greenhouse gas theories anticipate warming, Singer said. *** The U.N.s (IPPC) authors avoided connecting the dots and making the appropriate observations, despite having all the necessary data because the end result would run counter to their mission, Singer suggested.
