Stalagmites from the southernmost Andes

Über ScienceDirect bin ich auf den Abstract eines "Article in press" von Mangini et al. gestoßen. 

Ein kurzer Auszug:
A temperature-related change in rainwater isotope values modified the MA1 record during the Little Ice Age (~0.7-0.1 ka BP) that was ~1.5 °C colder than today. ... Our proxies indicate that the Neoglacial cold phases from ~3.5 to 2.5 and from ~0.7 to 0.1 ka BP were characterised by 30% lower precipitation compared with the Medieval Warm Period from 1.2 to 0.8 ka BP, which was extremely humid in this region.
