Cosmic rays redux

Almost a decade ago, I was nudged away from skepticism about anthropogenic global warming after writing an article for TCSDaily (aka Tech Central Station) titled "Cosmic Ray Days." I was reporting on some research that suggested cosmic rays could be an important factor in climate change, but I also noted the uncertainties involved and that one of the scientists doing the research still thought human activity might account for a third to a half of the warming at that point. My skepticism took a hit when TCS soon thereafter published a piece, based on the same research, that claimed that "a great mystery has been solved" and nonchalantly tossed away all the evidence for human activities being central.

Anyway, some people are still playing up the cosmic ray angle, regardless of its weakness.
