New paper finds solar activity an important influence on climate during the Medieval Warm Period
A paper published today in The Holocene reconstructs sea surface temperatures [SSTs] of the Southern Adriatic Sea during the Medieval Warm Period and finds "clear" evidence of solar influence on climate change. The authors find sea surface temperatures varied closely with 11 year solar cycles. According to the authors, "We observe a clear 11.4 year cyclicity in the reconstructed SST series. Furthermore, there is a good matching between SST and global 14C [temperature proxy] anomalies. This suggests that solar activity might have had an important influence on the local climate during Medieval time."
