Andes glaciers, ailing giants hit by climate change
2014-12-02 20:05:00| Climate Ark Climate Change & Global Warming Newsfeed
Agence France-Presse: Like ailing giants, the tropical glaciers of the Andes Mountains are melting at worrying speed, raising scientists' fears that many will disappear before anything can be done to save them. These icy castles, scattered across Ecuador, Bolivia, Colombia and Peru, are under a microscope at the United Nations climate talks this month in the Peruvian capital Lima, where 195 countries are trying to hammer out the framework of a global deal to cut the carbon emissions warming the planet. The melting...

Peru glaciers shrink 40% in 44 years: government
2014-10-16 22:58:00| Climate Ark Climate Change & Global Warming Newsfeed
Agence France-Presse: Peru's glaciers have shrunk by more than 40 percent since 1970 because of climate change, giving birth to nearly 1,000 new lagoons, national water authority ANA said Thursday. Peru, which is hosting the United Nations Climate Change Conference, or COP 20, in December, used satellite images to carry out the glacier inventory ahead of the high-level meeting. The worst-affected glacier was 5,200-meter-high (17,000-foot) tourist gem Pastoruri in the Andes mountains, which lost 52 percent of its...

Large Sediment Plumes Flowing from Greenland Glaciers, NASA Images Show
2014-10-02 20:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: Plumes of sediment-laden meltwater from southwest Greenlands glaciers are easily recognizable in this NASA satellite image captured in early September. Meltwater at the top of the ice sheet starts out relatively clean, but as it flows through glacial channels down to the ground and out into the ocean, it picks up large amounts of sediment a byproduct of the glacier scraping the bedrock. As a result, plumes, like the ones that appear light-blue in this photograph, are good markers for estimating...
Building an unmanned hydropower plant beneath Greenland's glaciers

Humans to Blame for World's Melting Glaciers
2014-08-15 22:05:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: As our world warms, glacial ice continues to retreat. However, scientists have now come to realize that humans are mostly to blame, rather than being able to solely peg it on natural climate fluctuations, according to a new study. Glacier extent actually responds very slowly to climate changes. In fact, it typically takes glaciers decades or centuries to adjust. The global retreat of these massive chunks of ice started around the middle of the 19th century at the end of the Little Ice Age. Though...
