Greenland melt could expose hazardous Cold War waste

Climate Central reports: When the U.S. military abandoned Camp Century, a complex of tunnels dug into the ice of northwest Greenland, in the mid-1960s, they left behind thousands of tons of waste, including hazardous radioactive and chemical materials. They expected the detritus would be safely entombed in the ice sheet for tens of thousands of years, buried ever deeper under accumulating layers of snow and ice.

But a new study suggests that because of warming temperatures that are driving substantial melting of the ice, that material could be exposed much, much sooner – possibly even by the end of this century – posing a threat to vulnerable local ecosystems.

These remnants of the Cold War are also an example of an unanticipated political issue that could arise because of the effects of climate change, particularly as countries seek to establish a presence in the Arctic as warming makes it increasingly accessible.

“We think it’s a nice case study for this kind of political tension stemming from climate change,” study author William Colgan, a glaciologist at York University in Toronto, said. [Continue reading…]
