Swiss tree rings reveal warm and wet summers during medieval times
[article]
2014
We present a 1200 year drought reconstruction for the European Alpine region based on carbon isotope variations of tree rings from living larch trees and historic timber. The carbon isotope fractionation at the study site is sensitive to summer precipitation, temperature, and irradiance, resulting in a stable and high correlation with a drought index for interannual to decadal frequencies and possibly beyond (r 2 = 0.58 for 1901-2004, July/August). When combining this information with maximum
