There is no "suppositions based upon more faulty suppositions" here? skepticalscience.com #1 It's the sun 8.9% Solar activity & climate: is the sun causing global warming? skepticalscience.com quote... As supplier of almost all the energy in Earth's climate, the sun certainly has a strong influence on climate change. Consequently there have been many studies examining the link between solar variations and global temperatures. The correlation between solar activity and temperature The most commonly cited study by skeptics is a study by scientists from Finland and Germany that finds the sun has been more active in the last 60 years than anytime in the past 1150 years (Usoskin 2005). They also found temperatures closely correlate to solar activity. However, a crucial finding was the correlation between solar activity and temperature ended around 1975. At that point, temperatures rose while solar activity stayed level. This led them to conclude "during these last 30 years the solar total irradiance, solar UV irradiance and cosmic ray flux has not shown any significant secular trend, so that at least this most recent warming episode must have another source." You read that right. The study most quoted by skeptics actually concluded the sun can't be causing global warming. Ironically, it's the sun's close correlation with Earth's temperature that proves it has little to do with the last 30 years of global warming. Maybe there is "suppositions based upon more faulty suppositions" but not of the kind that supports any of your arguments.
