  title={Support for global climate reorganization during the ‘ ‘ Medieval Climate Anomaly},
  author={Caspar M. Ammann and Dominik Fleitmann and Kim M. Cobb and Juerg Luterbacher},
Widely distributed proxy records indicate that the Medieval Climate Anomaly (MCA; *900–1350 AD) was characterized by coherent shifts in large-scale Northern Hemisphere atmospheric circulation patterns. Although cooler sea surface temperatures in the central and eastern equatorial Pacific can explain some aspects of medieval circulation changes, they are not sufficient to account for other notable features, including widespread aridity through the Eurasian sub-tropics, stronger winter westerlies… CONTINUE READING
