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 revealing its secrets. Using lab techniques unimaginable in the 1960s when the core was drilled, we a...

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 plant life under this apparently long-frozen part of the world. In a new study published this week i...

The mech...

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