Global Warming not Solar induced (from http://www.keelynet.com/#whatsnew)
Now it appears that the Sun has played only a minor role in frying the planet. Scientists have examined various proxies of solar energy output over the past 1,000 years and have found no evidence that they are correlated with today’s rising temperatures. Satellite observations over the past 30 years have also turned up nothing. “The solar contribution to warming . . . is negligible,” the researchers wrote in the journal Nature. The 11-year sunspot cycle also appears not to be linked to global warming. Production of beryllium 10, an isotope resulting from the interaction of cosmic rays and the upper atmosphere, should fall during periods of high solar activity; no such overall decrease was found in Greenland and Antarctic ice sheets over the past millennium. The researchers also discredit the idea that the Sun is implicated in past variations in climate. “Our results imply that over the past century climate change due to human influences must far outweigh the effects of changes in the Sun’s brightness,” said Tom Wigley, of the US National Centre for Atmospheric Research in Colorado, who co-authored the study.
