Scientists journeyed to Greenland in an unprecedented experiment to drill for rocks beneath the ice sheet. But a crack in the ice threatened their mission - and their ability to predict the fate of the warming world.

"Greenland has the potential to be one of the best discoveries of the past 100 years," Josh Goldman, the president of the startup KoBold Metals, told Newsweek.

In 2020, seismologist Goran Ekström noticed a peculiar wiggle picked up on Nov. 28 by seismographs around the world. It emanated from a remote area in British Columbia's steep, glaciated Central Coast Mountains, some 2,400 miles from Ekström's office at Columbia University's Lamont-Doherty Earth Observatory, in Palisades, N.Y.

Plant fossils, frozen under a kilometer and a half of ice in Greenland, represent a worrying indicator that this ice sheet has completely melted in previous warm periods. This is shown by the new study, published in the journal ‘Proceedings of the National Academy of Sciences’, provides solid evidence that Greenland is more sensitive to climate change than previously believed, and runs the risk of melting irreversibly. In 1966, US Army scientists drilled nearly a mile of ice in northweste...

In 1966, US Army scientists drilled down through nearly a mile of ice in northwestern Greenland -- and pulled up a fifteen-foot-long tube of dirt from the bottom. Then this frozen sediment was lost in a freezer for decades. It was accidentally rediscovered in 2017. In 2019, University of Vermont scientist Andrew Christ looked at it through his microscope -- and couldnt believe what he was seeing: twigs and leaves instead of just sand and rock. That suggested that the ice was gone in the recent ...

Story highlights The discovery of plants beneath ice in Greenland reveals that the region underwent melting at a scale similar to whats happening right now Scientists recently found plants beneath ice in Greenland, essentially rewriting what we know about previous warming periods in Earths history. The discovery of plants beneath ice reveals that the region underwent melting at a scale similar to whats happening right now. Within the last million years, the region underwent melting, similar to ...

Greenland Ice Sheet is More Sensitive to Climate Change than Previously Understood Written by AZoCleantechMar 16 2021 In 1966, US Army scientists drilled down through nearly a mile of ice in northwestern Greenland--and pulled up a fifteen-foot-long tube of dirt from the bottom.

BENEATH THE ICE The material for the new PNAS study came from Camp Century, a Cold War military base dug inside the ice sheet far above the Arctic Circle in the 1960s. The real purpose of the camp was a super-secret effort, called Project Iceworm, to hide 600 nuclear missiles under the ice close to the Soviet Union. As cover, the Army presented the camp as a polar science station. © University of VermontThe military mission failed, but the science team did complete important research, in...

The Zealandia Switch: Missing Link in Big Natural Climate Shifts? The Southern Hemisphere may be the missing link in answering longstanding questions about how ice ages wax and wane, according to a new study. There, say researchers, complex interactions among the westerly wind system, the Southern Ocean and the tropical Pacific can trigger rapid global changes in atmospheric temperature. The mechanism, dubbed the Zealandia Switch, relates to the position of the Southern Hemisphere westerly wind...
