Salvatore del Prete: Therefore the more correct interpretation of The Little Ice Age should be random climate fluctuation superimposed upon an overall lower mean temperature during the period of time The Little Ice Age took place, that being 1300ad-1850ad.
The authors say that if there was a “Little Ice Age” onset of the sort commonly described, then it must have occurred before their temperature series were started, so they can not rule it out.
“Stationary throughout the recorded interval up to about the end of the 19th century” is a reasonable summary of the AOAS paper and TonyB’s essay. Neither one of them can identify an end of the Medieval Warm Period, or an identifiable subinterval of the interval between the Medieval Warm Period and the “Modern Warm Period” that is a distinct “Little Ice Age”..
I don’t disagree with your “more correct” interpretation, but I don’t think it disagrees with what Kelly an O’Grada wrote.
