Muller bases his ‘conversion’ on the results of their recent paper?
So, how convincing is the analysis in Rohde et al.’s new paper A new estimate of the average surface land temperature spanning 1753-2011? Their analysis is based upon curve fits to volcanic forcing and the logarithm of the CO2 forcing (addition of solar forcing did not improve the curve fit.)
I have made public statements that I am unconvinced by their analysis. I do not see any justification in their argument for making a stronger attribution statement than has been made by the IPCC AR4. I have written MANY posts that critique the IPCC’s attribution analysis. Here I try to give a sense of the challenges in attributing climate change to causal factors.
