What aren't you going to claim Fagan and Pielou lied about the existence of the Medieval Warm Period to please their oil company paymasters? Re. your repeat of the idea that the MWP was a "regional" affair, I and other have already provided copious evidence to the contrary on this thread. It's easy to find: 1100 YEARS OF RAINFALL DATA FOR EAST AFRICA AVAILABLE FROM NOAA Data showing the amounts of rainfall in east Africa over the past 1,100 years are available from NOAA's National Geophysical Data Center in Boulder, Colo. The data were from sediment and fossils taken from a lake in Kenya. They were used to provide information about what the climate was like then. The sources, from Lake Naivasha in Kenya, include sediment and fossils. Using these and other sources, scientists determined that over the past millennium, the climate in equatorial east Africa has alternated between drier than today, and relatively wet. The drier climate took place during the Medieval Warm Period (~AD 1000-1270); the relatively wet climate during the Little Ice Age (~AD 1270-1850). The Little Ice Age was interrupted by three prolonged dry episodes .... publicaffairs.noaa.gov The Little Ice Age, from around 1300 to 1800, and medieval warming, from before 1000 to around 1300 in South Africa, are shown to be distinctive features of the regional climate of the last millennium. The proxy climate record has been constituted from oxygen and carbon isotope and colour density data obtained from a well-dated stalagmite derived from Cold Air Cave in the Makapansgat Valley. The climate of the interior of South Africa was around 1oC cooler in the Little Ice Age and may have been over 3°C higher than at present during the extremes of the medieval warm period. www-user.zfn.uni-bremen.de
