Cold War-era radioactive waste stored under Greenland's ice could be released as global temperatures rise
2016-08-06 01:56:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: Global warming could release radioactive waste stored in an abandoned Cold War-era U.S. military camp deep under Greenland's ice caps if a thaw continues to spread in coming decades, scientists said on Friday. Camp Century was built in northwest Greenland in 1959 as part of U.S. research into the feasibility of nuclear missile launch sites in the Arctic, the University of Zurich said in a statement. Staff left gallons of fuel and an unknown amount of low-level radioactive coolant there when...

How to deal with toxic waste buried in Greenland's rapidly melting ice caps
2016-08-05 15:22:00| Climate Ark Climate Change & Global Warming Newsfeed
Monitor: Climate change is bringing a lot of first-time environmental challenges, as well as many unprecedented political challenges. And one such climate change challenge could be particularly political. Greenland's ice sheet is melting at a rapid pace. According to a new study published Wednesday in the journal Geophysical Research Letters, this significant snow and ice loss could cause buried toxic waste to resurface unexpectedly. Camp Century was a US military base built on and under the Greenland...
Scientists say Greenlands vast melt hasnt slowed down the Atlantic Oceans circulation yet
2016-06-21 15:05:48| Climate Ark Climate Change & Global Warming Newsfeed
Washington Post: Last year, a bombshell scientific study suggested a scenario that has long worried scientists was coming to pass: a slowdown in the North Atlantic ocean currents that usually redistribute warm and cold waters, thanks to massive ice melts in Greenland and other Arctic changes. If this is really happening, its a big deal. The circulation, sometimes called the Atlantic meridional overturning circulation or AMOC, transports enormous amounts of warmth northward from lower latitudes. If it slows down,...

Weird jet stream behavior could be making Greenlands melting even worse, scientists say
2016-06-11 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Washington Post: The vast northern ice sheet of Greenland melts every summer, pooling lakes of meltwater on its surface and losing fleets of icebergs from its finger-like glaciers. Thats not surprising -- its summer -- although in a warming climate, there are reasons to think these melt seasons are getting more intense, pouring more and more freshwater into the ocean. But when a group of scientists looked back at the last summer melt season -- 2015 -- they found something odd and troubling. Specifically,...

Greenland's 2015 melt records consistent with 'Arctic amplification'
2016-06-10 13:32:00| Climate Ark Climate Change & Global Warming Newsfeed
Environmental News Network: Following record-high temperatures and melting records that affected northwest Greenland in summer 2015, a new study provides the first evidence linking melting in Greenland to the anticipated effects of a phenomenon known as Arctic amplification. Arctic amplification, in the simplest terms, is the faster warming of the Arctic compared to the rest of the Northern Hemisphere as sea ice disappears. It is fueled by a feedback loop: rising global temperatures are melting Arctic sea ice, leaving dark...
