Description
The authors analyzed δ13C variations of Japanese cedars growing on Yakushima Island, southern Japan (3020'N, 13030'E), in an effort to reconstruct a high-resolution proxy temperature record over the past two thousand years. The Medieval Warm Period occurred between AD 800-1250 and from the authors' Figure 3, peak warmth during this time was about 1C above that of the Current Warm Period.
