Giftiges Erbe des Kalten Kriegs taucht auf
Grönland: Eisschmelze könnte geheime US-Militärbasis mitsamt Giftstoffen freilegen
Es klingt wie ein Thriller – ist aber Realität: Eine geheime US-Militärbasis aus dem Kalten Krieg liegt unter dem Eis Grönlands versteckt – und droht nun durch die Eisschmelze ans Tageslicht zu kommen. Das Gefährliche daran: Als "Camp Century" aufgegeben wurde, ließ man große Mengen an giftigen Abfällen und schwach radioaktives Kühlwasser einfach zurück. Doch das arktische Tauwetter könnte dieses giftige Erbe noch vor Ende des Jahrhunderts freilegen, warnen Forscher.

Abstract
In 1959 the U.S. Army Corps of Engineers built Camp Century beneath the surface of the northwestern Greenland Ice Sheet. There they studied the feasibility of deploying ballistic missiles within the ice sheet. The base and its wastes were abandoned with minimal decommissioning in 1967, under the assumption they would be preserved for eternity by perpetually accumulating snowfall. Here we show that a transition in ice sheet surface mass balance at Camp Century from net accumulation to net ablation is plausible within the next 75 years, under a business-as-usual anthropogenic emissions scenario (Representative Concentration Pathway 8.5). Net ablation would guarantee the eventual remobilization of physical, chemical, biological, and radiological wastes abandoned at the site. While Camp Century and four other contemporaneous ice sheet bases were legally established under a Danish-U.S. treaty, the potential remobilization of their abandoned wastes, previously regarded as sequestered, represents an entirely new pathway of political dispute resulting from climate change
