The Greenland ice sheet contains enough water to raise global sea levels 7m should it all melt. And a massive melt-out is exactly what seems to have happened about a million years ago, according to a groundbreaking analysis of a unique geologic sample from Greenland's rocky underbelly.

During the Cold War, the US Army studied the feasibility of launching ballistic missiles from within Greenland's ice sheet. When the project was done, engineers buried biological, chemical and radioactive waste in the ice thinking it would be preserved for eternity. Shame they didn't know about global warming.
