Comment, Judith Currie on Muller's 'BEST'

With regards to the new paper, I strongly disagree with their interpretation of attribution. The scientific analyses that the BEST team has done with the new data set are controversial, including the impact of station quality on interpreting temperature trends and the urban heat island effect. Their latest paper on the 250 year record concludes that the best explanation for the observed warming is greenhouse gas emissions. In my opinion, their analysis is way over simplistic and not at all convincing. There is broad agreement that greenhouse gas emissions have contributed to the warming in the latter half of the 20th century; the big question is how much of this warming can be attributed to greenhouse gas emissions. I don’t think this question can be answered by the simple curve fitting used in this paper, and I don’t see that their paper adds anything to our understanding of the causes of the recent warming.
