The Upsala Glacier is a large valley glacier flowing from the Southern Patagonia Ice Field, which also feeds Perito Moreno Glacier. Upsala is often seen as evidence of global warming because the glacier is disappearing at a rate of 200 meters per year. Other scientists say its reduction is due to complicated shifts in glacial dynamics and local geology. Either way, glacial retreat has large implications, especially in South America and Asia, where rural and urban populations rely on seasonal meltwater. Civil engineers have long been working on methods of harvesting glacier ice to provide clean drinking water, support agriculture, and recharge the groundwater. One method involves creating artificial glaciers by channeling and freezing water through metal pipes, delivering the ice closer to where water is needed.http://www.allaboutar.com/ard_calafate_upsala_glacier.htmhttp://nsidc.org/glaciers/http://www.worldviewofglobalwarming.org/pages/glaciers.htmlhttp://www.worldviewofglobalwarming.org/pages/glaciers.htmlhttp://thescientistgardener.blogspot.com/2009/11/engineering-glaciers.htmlshapeimage_4_link_0shapeimage_4_link_1shapeimage_4_link_2shapeimage_4_link_3shapeimage_4_link_4
