Kate Lunau, reporting Motherboard:Greenland isn't happy about being treated as a dumping ground for abandoned US military bases established at the height of the Cold War -- and in a newspaper editorial, it's calling on Denmark to deal with the mess left behind by the Americans, since the Danish long ago took responsibility for them. This editorial notes that, after decades, Greenland is "losing its patience." One of the abandoned bases, called Camp Century, is full of nasty chemicals and some radioactive material, as Motherboard previously reported. At Camp Century, which was built in 1959, soldiers called "Iceworms" practiced deployment of missiles against Russia and literally lived inside the ice. When the US decommissioned the base in the 1960s, the military left basically everything behind, thinking that its waste would stay locked up in the Greenland ice sheet forever. Well, climate change has made that unlikely. Melting ice threatens to expose all kinds of toxic debris in decades to come, and Greenland wants it cleaned up, now.
