Cosmic Rays, Carbon Dioxide and Climate: Rebuttal of Shaviv and Veizer
Excerpt: " We thus find that there is no significant correlation of the CRF curve from Shaviv’s model and the temperature curve of Veizer, even after one of the four CRF peaks was arbitrarily shifted by 40 m.y. to improve the fit to the temperature curve. There also is no significant correlation between the original meteorite data and the temperature reconstruction. The explained variance claimed by [Shaviv and Veizer, 2003] is the maximum achievable by optimal smoothing of the temperature data and by making several arbitrary adjustments to the cosmic ray data (within their large uncertainty) to line up their peaks with the temperature curve."
As an aside, Jan Veizer is a great scientist, and you don't become a great scientist without taking a few risks.
Interesting that article had nothing to say concerning the correlations with current measures of CRF & lower cloud cover, nor the multiple studies that do reflect the geological trends overall.
One indeed must look at the whole as well.
