The geological factual basis is clear: Fluctuations in solar activity significantly influenced the development of the climate throughout the history of the Earth.

Today’s IPCC is clueless. With its simplistic approach, the IPCC is not able to reproduce the documented climate fluctuations of the past. The gross fundamental errors aren’t of any help at all for the most powerful computers. In the search for additional links in the sun-climate-impact, Willie Soon of the Harvard-Smithsonian Center for Astrophysics and David Legates of the College of Earth, Ocean, and Environment at the University of Delaware came across an exciting relationship. In a mutual study that appeared in the February 2013 Journal of Atmospheric and Solar-Terrestrial Physics, the scientists were able to show a relationship between solar activity fluctuations and the temperature gradient between the North Pole and the equator over a timescale of multiple decades.

This means that the craft of modelling has got lots of homework to do. Up to now the models have not been able to simulate this effect. Now they are forced to check over, sort out, supplement, and improve their formulas. It’s back to the drawing board!
