  • Greenland Rising: The Future of Greenland’s Waterfront

    Greenland Rising: The Future of Greenland’s Waterfront

    While much of the world is planning for flooding and inundation from changes in sea level, Greenland is facing a much different future.

  • New Project Will Study Greenland’s Helheim Glacier in Unprecedented Detail

    New Project Will Study Greenland’s Helheim Glacier in Unprecedented Detail

    Using drones, laser scanners, and high-resolution models, researchers hope to find out more about the processes driving rapid melting in this region.

  • It’s Raining on the Greenland Ice. In the Winter.

    It’s Raining on the Greenland Ice. In the Winter.

    Rainy weather is becoming increasingly common over parts of the Greenland ice sheet, triggering sudden melting events that are eating at the ice and priming the surface for more widespread future melting, says a new study.

  • Uncovering the Future of Greenland’s Ice Sheet

    Uncovering the Future of Greenland’s Ice Sheet

    Joerg Schaefer and Gisela Winckler, scientists at Lamont-Doherty Earth Observatory, received funding from the Center for Climate and Life to examine the vulnerability of Greenland’s massive ice sheet.

  • The Melting of the Greenland Ice, Seen Up Very Close

    The Melting of the Greenland Ice, Seen Up Very Close

    A small team of scientists ventures out onto the Greenland ice sheet to study the forces large and small that are accelerating the melting of the world’s second-largest ice mass.

    As climate warms, the Greenland ice sheet is melting, helping to fuel global sea-level rise. Follow a small team of scientists as they hike onto the sheet to investigate the forces large and small that are demolishing the ice.

  • The Story of Lake Gus

    The Story of Lake Gus

    For this early part of the season the goal is to tease apart a record of historic precipitation and temperature for this region using isotopes from leaf waxes collected in the lake sediments.

  • Scientists Are Superheroes With Super Powers

    Scientists Are Superheroes With Super Powers

    Superheroes are identified by their unique powers and skills, allowing them to see and act in ways that inspire awe in the rest of us. Do scientists have superhero powers?

  • The Greenland Ice Sheet Is Sponging Up Meltwater

    The Greenland Ice Sheet Is Sponging Up Meltwater

    As climate warms, the surface of the Greenland ice sheet is melting, and all that meltwater ends up in seasonal rivers that flow to the sea. At least that is what scientists have assumed until now. A new study has shown that some of the meltwater is actually being soaked into porous subsurface ice and…
