Link between Cosmic Ray Flux and Global Temperature found

From the paper in PNAS:(h/t to Dr. Leif Svalgaard) Our results suggest weak to moderate coupling between CR and year-to-year changes of GT,” they write. “However, we find that the realized effect is modest at best, and only recoverable when the secular trend in GT is removed.” This “secular trend” is the warming widely believed…

Cosmic Rays and Climate – to be or not to be?

From the “science is still settling” department, the question still seems up in the air to me. On one hand we have Dr. Jasper Kirkby, Head of the CLOUD Experiment, CERN Geneva giving a thorough review showing strong correlations between cosmic rays, solar cycles and earth’s climate. He projects a possible mini ice age by…

Study says global warming caused by CFCs interacting with cosmic rays, not carbon dioxide

From the University of Waterloo, an extraordinary claim. While plausible, due to the fact that CFC’s have very high GWP numbers, their atmospheric concentrations compared to CO2 are quite low, and the radiative forcings they add are small by comparison to CO2. This may be nothing more than coincidental correlation. But, I have to admit,…
