Most of the world’s mountain glaciers have been retreating for more than a century in response to climate change. Glacier retreat is evident on all continents, and rate has accelerated during recent decades. Accurate, spatially explicit information position glacier margins over time useful analyzing patterns measuring reductions surface area. This also essential evaluating how ecosystems are ev...

Records of discharge of rivers draining Alpine basins with between 0 and 70% ice cover, in the upper Aare and Rhône catchments, Switzerland, for the period 1894–2006 have been examined together with climatic data for 1866–2006, with a view to assessing the effects on runoff from glacierized basins of climatic warming coupled with glacier recession following the Little Ice Age maximum. Annual ru...
