The discovery of fossil plants below a mile of Greenland ice indicates that the ice sheet completely melted in the past, and suggests it could rapidly do so again.

Using radar and other techniques, researchers have mapped out the sediments left by a lake that apparently existed before Greenland was glaciated. Next step: drilling through the ice to see what they contain.

To measure algal blooms across large regions of the Greenland ice, and understand their effects on melting over time, scientists are turning to space.

He’s working to make the geosciences an area where everyone can thrive.

In this episode, Kevin Krajick explores Marco Tedesco’s obsession with the cryosphere—the part of earth that consists of frozen water.

In another sign of the warming Arctic, satellite images from July 2020 show that the St. Patrick Bay Ice Caps on Canada’s Ellesmere Island have completely melted, as predicted in 2017.

In a new book, glaciologist Marco Tedesco takes the reader on a personal journey through his sometimes dangerous work.

GreenDrill promises to reveal the ice sheet’s past in unprecedented detail and enable more accurate predictions of how it may add to rising seas in the 21st century.

Reductions in human emissions and changes in atmospheric composition during the coronavirus pandemic might be observed in future glacial ice cores.

In a new study, researchers propose a mechanism for how mega-canyons under northern Greenland’s ice sheet formed: from a series of catastrophic outburst floods that suddenly and repeatedly drained lakes of meltwater.
