So what do the climate Cluesos have to tell us this time? Have they now successfully identified a human influence on the climate system? The Fun thing about the title is that it is immediately contradicted by the abstract, in which we find this telling passage:
"We use simulation output from 20 climate models participating in phase 5 of the Coupled Model Intercomparison Project. This multimodel archive provides estimates of the signal pattern in response to combined anthropogenic and natural external forcing (the finger- print) and the noise of internally generated variability. Using these estimates, we calculate signal-to-noise (S/N) ratios to quantify the strength of the fingerprint in the observations relative to fingerprint strength in natural climate noise."
