Description
Summary:In Central Asia, Pleistocene glaciations occurred in two climatic regimes: arid regions where annual precipitation was Mountain glaciers in arid Central Asia are important in and of themselves because their meltwater is necessary to sustain some communities through dry seasons when rainfall is slight. Furthermore, glaciers are commonly associated with ice-dammed lakes that can rupture to release dangerous outburst floods downstream. However, because of their widespread distribution in Central Asia, the most significant role for glaciers may be as a warning system for climate change and a signal for the degradation of permafrost and consequent release of greenhouse CH4 into the atmosphere.
