    Spy Satellites Reveal the Himalayas’ Changing Glaciers – in 3D

    Declassified spy satellite images are beginning to provide the first consistent look at how glaciers across the Himalayas are changing and what future water supplies might look like for millions of people.

    Live from San Francisco: Science from Lamont

    Earth scientists from around the world will be in San Francisco next week to share their latest discoveries at the American Geophysical Union’s fall meeting. You can watch several of their presentations live online through AGU On-Demand, including seven involving scientists from Lamont-Doherty Earth Observatory.

  • The ‘Bird’ Has Flown!

    The ‘Bird’ Has Flown!

    The ‘bird’ has flown! Voices are raised in celebratory cheers from the southernmost continent to across the U.S. Our first ALAMO float is deployed! Now we can begin to answer some of the big questions on this mysterious ice/ocean interface.

    When Permafrost Melts, What Happens to All That Stored Carbon?

    A new study documents evidence of a massive release of carbon from Siberian permafrost as temperatures rose at the end of the last ice age.

    Antarctica Has a New Explorer in the Water Near a Key Ice Shelf

    The first of six ALAMO floats parachuted into the Ross Sea off Antarctica to begin profiling the water in a check for areas where warmer than normal water could put the Ross Ice Shelf at risk.

    AGU 2016: Key Events From the Earth Institute

    Scientists at Columbia University’s Earth Institute will present important findings at this year’s meeting of the American Geophysical Union, the world’s largest gathering of earth and space scientists.

  • ‘Ghost Ice Shelves’ and the Third Antarctic Ice Sheet

    ‘Ghost Ice Shelves’ and the Third Antarctic Ice Sheet

    The Antarctica Peninsula has been referred to as Antarctica’s third ice sheet. Following behind the East and West Antarctic ice sheet in size, one might be inclined to minimize its importance in the effects of melting Antarctic ice, on changes in sea level and other impacts, but that would be an imprudent mistake. The peninsula…

    Photo Essay: Where the Trees Meet the Tundra

    Due to warming climate and increasing human exploitation, far northern forests and the tundra beyond are undergoing rapid changes. In northern Alaska, scientists from Columbia University’s Lamont-Doherty Earth Observatory and other institutions are studying the responses of trees at the very edge of their range.

    Where Trees Meet Tundra, Decoding Signals of Climate Change

    In northern Alaska’s Brooks Range, the earth as most of us know it comes to an end. The northern tree line-a boundary that circles all of earth’s northern landmasses for more than 8,300 miles, and forms the planet’s biggest ecological transition zone–runs through here. Scientists from Columbia University’s Lamont-Doherty Earth Observatory are studying how climate…
