Greenland Ice Sheet8

  • Ice Cube Science

    We have flown three flights in the last week, with a fourth postponed as winds were too high for take off. Two of the flights have focused on sea ice in the Arctic. The first was flown north of Canada’s Ellsmere Island, where thick multiyear ice tends to accumulate. We examined the thickness of that…

  • Following Arctic Leads

    Our ICE Bridge team of 34 scientists and NASA personnel has piled mounds of equipment, luggage, and emergency Arctic survival gear into the DC-8, setting off just before midnight for Thule, Greenland.All but two of the seats are filled, and every possible open area has been piled with our supplies for the next few weeks.Our…

  • California ‘shake down’ starts Greenland trip!

    Jim Cochran, Geophysicist, Lamont-Doherty Earth Observatory ICE Bridge scientists gathering at NASA’s Dryden Flight Research Center (DFRC) in Palmdale, CA for our upcoming Greenland mission were greeted in true California style. We were awakened by a magnitude 4.4 earthquake in the middle of the night! Although small by California standards the event was centered only about…

  • Look At Glaciers Past Suggests Greenland Melting Could Rapidly Heighten Sea Level

    North American Ice Sheet Dwindled Fast in Conditions Like Today’s

  • Glacial Earthquakes Point to Rising Temperatures in Greenland

    Rise of seismic activity linked to the movement of glaciers may be a response to global warming

  • Study Offers Preview of Ice Sheet Melting, Rapid Climate Changes

    Behavior of Scandinavian Ice Sheet at the end of the last Ice Age may preview loss of Greenland Ice Sheet due to global warming

AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana. This year’s theme—Where Science Connects Us—puts in focus how science depends on connection, from the lab to the field to the ballot box. Once again, Lamont-Doherty Earth Observatory and Columbia Climate School scientists, experts, students, and educators are playing an active role, sharing our research and helping shape the future of our planet. #AGU25 Learn More
