The search for a solar-climate link continues. James Annan reports:
[T]he field basically consists of little more than people data-mining for correlations that usually fail to hold when tested on out of sample data, and for which there is no real evidence or even plausible modelling to support the hypothesis that there may be a significant effect. Of course it is obvious enough that gross changes in solar output will have some sort of effect, such as the orbital changes at Milankovitch time scales, and a modest sunspot-related influence. But nothing of much significance in the context of anthropogenic global warming.
