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.

Predicting the future is near impossible -- but that doesn‘t stop us all from having a red hot go. Human beings have been predicting the future since the beginning of history and the results range from the hilarious to the downright uncanny.

One thing all future predictions have in common: they‘re rooted in our current understanding of how the world works. It‘s difficult to escape that mindset. We have no idea how technology will evolve, so our ideas are connected to the technology of today.
