Variations on Sun’s role in climate change

We enjoyed the article titled “Is Climate Sensitive to Solar Variability?” We commend Nicola Scafetta and Bruce West for their courage in publishing a scientific piece that presents a socially and politically unpopular position.

However, we are concerned about the article’s placement in Physics Today as an opinion piece. Considering the physical arguments, the reliance on observational and citable data sets, and the attention to mathematical rigor, we wonder what portion of the article is opinion.
