In 1963, inside a covert U.S. military base in northern Greenland, a team of scientists began drilling down through the Greenland ice sheet. Piece by piece, they extracted an ice core 4 inches across and nearly a mile long. At the very end, they pulled up something else – 12 feet of frozen soil. The ice told a story of Earth’s climate history. The frozen soil was examined, set aside and then forgotten. Half a century later, scientists rediscovered that soil in a Danish freezer. It is now r...

By Kevin Krajick In 1966, U.S. Army scientists drilled through nearly a mile of ice in northwestern Greenland and pulled up a 15-foot-long core of sediment from the bottom. The sample, abandoned and largely forgotten in a series of freezers for decades, was accidentally rediscovered in 2017. Researchers who later examined it were stunned to find it contained not just the usual sand and rock found under glacial ice, but well-preserved remains of twigs and leaves—the first discovery of onetime ...

A massive surge of rock, debris, and icy water killed more than 50 people in Uttarakhand this month. Nearly 150 others are still missing.

BY: JULIA JACOBO, ABC NEWS (NEW YORK) — Warming temperatures across the globe are changing landscapes and threatening local cities and communities. A devastating break of a glacier in the Himalayas on Feb. 7 left dozens dead and more than 100 missing after it smashed into multiple dams, collecting debris and energy as it made [...]

A devastating break of a glacier in the Himalayas on Feb. 7 left dozens dead and more than 100 missing after it smashed into multiple dams, collecting debris and energy as it made its way down the flank before slamming into two hydroelectric plants in northern India. ...

Updated Feb 08, 2021 | 14:10 IST The monster of climate change has a firm grip on the ecological balance of the world. Disasters such as Chamoli and Kedarnath flashfloods are likely to get more frequent as glaciers lose more mass.

December 12, 2020 It’s AGU Fall Meeting week, and the Science stories typically hit peak volume during this time. This story is spectacular. Paul Voosen in Science: BURLINGTON, VERMONT—In one of the Cold War’s oddest experiments, the United States dug a 300-meter-long military base called Camp Century into the ice of northwest Greenland in the early 1960s, powered it with a nuclear reactor, and set out to test the feasibility of shuttling nuclear missiles beneath the ice. A constant strug...
