We noticed this daft report in ScienceDaily (May 12, 2009) Changes In The Sun Are Not Causing Global Warming, New Study Shows
, and were glad to come across comments by Doug L Hoffman....such is the wonder of Google....H/T ClimateDepot.Com
Two computer modelers from CMU have written a program to simulate the interaction of cosmic rays with Earth's atmosphere. Because the model failed to predict significant increases in cloud cover, global warming activists are claiming the theory linking cosmic rays to climate change has been discredited. Climate models have failed to accurately predict the current downward trend in temperatures and now we are asked to accept a model as proof of how the Universe works. In truth, the paper cited is nothing more than a study of a computer program, and has nothing to do with the physical reality of how Earth's climate functions.
Appearing in Science under the title, “Study Challenges Cosmic Ray–Climate Link,” a review of the paper by Jeffrey Pierce and Peter Adams of Carnegie Mellon University in Pittsburgh, Pennsylvania, was used as an excuse to cast doubt on the theory that cosmic ray levels affect the creation of clouds in Earth's atmosphere. This theory was first proposed in 1997 by physicists Henrik Svensmark and Eigil Friis-Christensen of the Technical University of Denmark in Copenhagen.
