PNAS Study shows powerful correlation between sun and climate over the last 9000 years.

    A paper in the Proceedings of the National Academy of Sciences in the US by Dr S Luning and Professor Fritz Vahrenholt notes that the comparison of solar activity(blue curve) and the Asian climate development (green curve, isotope O18 of a stalagmite in a Chinese cave) for the past 9000years clearly shows a good agreement between the two curves, which strongly suggests a significant climate impact by the sun.  Also the IPCC has ignored that G Bond was able to show more than 10 years ago that the last 10 000 years have been characterized by a global temperature that runs up and down in sync with solar activity(Bond et al 2001). reference P Gosselin   www.notrickszone .com  German climate science in English
