Greenland ice is melting. This week, as a new map showed where Greenland’s bedrock ice is still solid and where’s it’s now melting, an unrelated study said that – as the ice melts – toxic and radioactive waste left behind at a Cold War-era hidden military base in Greenland could be released as early as 2090. The journal Geophysical Research Letters published the study on August 4, 2016.
Greenland’s Camp Century was part of a top-secret project called Iceworm. The original plan was to build a network of mobile nuclear missile launch sites under the Greenland ice sheet. The U.S. Army built Camp Century within the Greenland ice sheet in 1959. It consists of a couple of dozen of underground tunnels, made of ice and hardened snow and steel, once capable of accommodating 200 people. A portable nuclear reactor supplied the power.
In its day, the camp was considered extremely technologically advanced. But, as it tends to do, nature proved stronger. Unsteady ice conditions within the ice sheet caused the project to be canceled in 1966. When the camp was decommissioned in 1967, its infrastructure and waste were abandoned under the assumption they would be entombed forever in Greenland’s ice.
That assumption, too, was wrong.
The new study shows that the portion of the ice sheet covering Camp Century will likely start to melt by the end of this century. Camp Century is is covered with 115 feet (35 meters) of snow and ice now, but, as the ice melts, any remaining biological, chemical and radioactive waste will be exposed to the surface. This waste could re-enter the environment and potentially disrupt nearby ecosystems.
The Cooperative Institute for Research in Environmental Science (CIRES) at University of Colorado, Boulder and the American Geophysical Union jointly released a statement this week about the soon-to-be-uncovered waste at Camp Century.
The statement said that determining who is responsible for cleaning up the waste could also lead to political disputes not considered before. William Colgan, a climate and glacier scientist at York University in Toronto, Canada, and lead author of the new study, commented:
Two generations ago, people were interring waste in different areas of the world, and now climate change is modifying those sites. It’s a new breed of political challenge we have to think about.
James White, a climate scientist at the University of Colorado in Boulder, who was not connected to the study, added that it’s unrealistic to think that buried toxic waste will always stay buried:
The question is whether it’s going to come out in hundreds of years, in thousands of years, or in tens of thousands of years.
This stuff was going to come out anyway, but what climate change did was press the gas pedal to the floor and say, ‘it’s going to come out a lot faster than you thought.
Bottom line: Cold War-era Camp Century in Greenland is currently buried beneath many meters of ice and snow. But the ice is melting. A new study shows that Camp Century could be exposed to the surface as early as 2090, releasing any remaining biological, chemical and nuclear waste to the environment.
