Fooled Again

A recent post on RealClimate discusses how easy it is to get fooled when analyzing data. It focuses on two recent papers, which critique other papers that go astray in assessing the relationship between solar activity and climate. I’d like to discuss one of those critiques, Legras et al. 2010, A critical look at solar-climate relationships from long temperature series (Climate of the Past, 6, 745-758, doi:10.5194/cp-6-745-2010).
