Andes' tropical glaciers 'going fast'
2013-04-10 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Daily Climate: The glaciers of the tropical Andes have shrunk by between 30 and 50 percent in 30 years and many will soon disappear altogether, cutting off the summer water supply for millions of people, according to scientists studying the region's climate. Their findings are particularly significant because glaciers in the tropics 99 percent of which are in the Andes are regarded as among the most sensitive indicators of climate change on the planet, according to the Intergovernmental Panel on Climate...

Peru bores through Andes to water desert after century of dreams

Reuters: Peru's Olmos Valley might be a desert now, with rare rains and rivers that trickle to life for just a few months a year, but a radical engineering solution for water scarcity could soon create an agricultural bonanza here. Fresh water that now tumbles down the eastern flank of the Andes mountains to the Amazon basin and eventually the Atlantic Ocean will instead move west through the mountains to irrigate this patch of desert on Peru's coast. It will then drain into the Pacific Ocean. The Herculean...

1,600 Years of Ice in Andes Melted in 25 Years, in Sign of Warming
2013-04-05 07:31:00| Climate Ark Climate Change & Global Warming Newsfeed
New York Times: Glacial ice in the Peruvian Andes that took at least 1,600 years to form has melted in just 25 years, scientists reported Thursday, the latest indication that the recent spike in global temperatures has thrown the natural world out of balance. The evidence comes from a remarkable find at the margins of the Quelccaya ice cap in Peru, the world's largest tropical ice sheet. Rapid melting there in the modern era is uncovering plants that were locked in a deep freeze when the glacier advanced many thousands...

Meltwater catastrophes are forming high in the Andes
2013-03-15 14:38:19| Climate Ark Climate Change & Global Warming Newsfeed
ClimateWire: Glacial melt is a popular topic in global warming discussions, with its contribution to rising sea levels and shrinking freshwater supplies among the main concerns. But for mountainous communities in Peru, such long-term worries are obscured by a much more imminent threat -- glacial lake outburst flows, called GLOFs -- poised just above them. Last month, the Risk Management Office of the Peruvian Municipality of Huaraz sounded the alarm that glacial lake Palcacocha had once again swollen above...
