re: Cosmic Rays & Climate Change
ER — (archived)

I don't know if this is very convincing. The cosmic ray flux is relatively constant, and if it is indeed modulated by solar activity, one would expect to see the effects blamed on solar activity, i.e., the alleged effects on climate would have been identified with known solar cycles. In other words, even though cosmic rays may be causing the climate to change, the solar activity is the driver that would have been blamed for it, even if it was only a secondary cause.

This popular account doesn't go into the details very thoroughly, and perhaps I'm missing something, but any correlation with solar activity and climate should have been apparent long before cosmic rays were identified as the underlying cause. The evidence so far is indeed tenuous.
