Climate Science in the Fjords of Greenland

Greenland’s ice sheets are shrinking faster than ever, responsible for about a quarter of sea-level rise globally. From a tiny hunting and fishing village in the Upernavik Islands on the northwest coast of Greenland, scientists Margie Turrin and Dave Porter are taking ocean measurements to understand why Alison Glacier is surging to the sea faster than nearby glaciers.

Slowing Currents May Have Flipped Ice Age Switch

For decades, climate scientists have tried to explain why ice-age cycles became longer and more intense about 900,000 years ago, switching from 41,000-year cycles to 100,000-year cycles. New research published in the leading journal Science by Leopoldo Pena and Steve Goldstein found that the deep ocean currents that move heat around the globe stalled or even stopped, possibly due to expanding ice cover in the north.

Frozen World Discovered Beneath Greenland Ice Sheet

Beneath the barren whiteness of Greenland, a mysterious world has popped into view. Using ice-penetrating radar, Lamont researchers have discovered ragged blocks of ice as tall as city skyscrapers and as wide as the island of Manhattan at the very bottom of the ice sheet. The newly revealed forms may help scientists understand more about how ice sheets behave and how they will respond to a warming climate.
