The suggestion that recent warming is anthropogenic due to divergence from a simple 60/20 year curve fit over a mere 100 years ignores prior divergence from both competing models of distantly past temperature, one being a hockey stick that shows a slow decline instead of incline prior 1850 and the other showing two similar «non-cyclical» spikes in the Roman and medieval periods.
