enhanced summer monsoon circulation, that glacier advances during the Last Glacial Maximum were less extensive in the Karakoram and western Himalayas, and that precipitation rather than temperature change dominated glacier fluctuations over the last glacial cycle. The discrepancy might point to different responses of glaciers to climatic change on different timescales. Presently, the available absolute dates on glacier chronologies are very limited and the sparse spatial coverage of evidence of glacier fluctuations does not yet allow us to draw final conclusions about the connection between climate change and glacier behavior in this topographically and climatically complex region.
