New Study: 2,300-Year Climate Record from the Andes

Science Daily News reports on a new sediment core study from the Andes, published in the Proceedings of the National Academy of Sciences.   The research, led by a team from the University of Pittsburgh, confirms previous research suggesting lower precipitation in the region during the Medieval Climatic Anomaly, culminating in a major drought ~1000-1040AD, coinciding with the decline of the Tiwanaku civilization.  The findings also point to a wetter period during the Little Ice Age and reduced precipitation since 1900, which the authors link to changes in ENSO and ITCZ patterns.
