Long-lost samples of twigs and rocks show that Greenland once lost a tremendous amount of ice under climate conditions very much like the ones humans are currently living in - implying coasts could soon be submerged under several feet of sea level rise.
. That is well above the highest temperatures reached during Marine Isotope Stage 11.
It didn’t take long for the motion of the ice sheet — which is constantly flowing under the pressure of its own weight — to expose the folly of this scheme. Tunnels collapsed, equipment malfunctioned and the encampment was eventually abandoned. Thousands of tons of building materials, unused diesel fuel and radioactive waste were left to languish under the ice.The project did yield one breakthrough.
Exposing the sediments to light is like dunking the shirt in bleach — the accumulated detritus of centuries is instantly lost.

Long-lost Greenland ice core suggests potential for disastrous sea level rise | CNNA recently-discovered ice core taken from beneath Greenland’s ice sheet decades ago reveals that much of the country was ice-free around 400,000 years ago – an alarming finding that could have disastrous implications for sea level rise.

Much of Greenland's ice could melt even if world doesn't get warmerA sediment core from Greenland shows that even if the planet does not get any warmer than it is now, ice loss from Greenland alone would add at least 1.5 metres to the global average sea level and possibly as much as 5 metres.

Greenland ice core suggests potential for disastrous sea level riseThe study overturns previous assumptions that most of Greenland’s ice sheet has been frozen for millions of years, the authors said. Instead, moderate, natural warming led to large-scale melting an…
