    Melting Glaciers Help Spur a Message on Climate

    On Oct. 5, several small mountain countries with glaciers—Austria, Bolivia, and Nepal—undertook an important step in advancing global action on climate change. They helped the Paris Climate Agreement reach the threshold to enter into force and become legally binding.

  • Massive Landslide Detected in Glacier Bay’s Fragile Mountains

    Massive Landslide Detected in Glacier Bay’s Fragile Mountains

    A 4,000-foot-high mountainside collapsed in Glacier Bay National Park this week in a massive landslide that spread debris for miles across the glacier below. Scientists at Lamont-Doherty Earth Observatory are studying it to improve understanding of landslide risks.

  • Crushing Ice to Learn About Glaciers & Icy Moons

    Crushing Ice to Learn About Glaciers & Icy Moons

    To understand how quickly ice from glaciers can raise sea level or how moons far across the solar system evolved to hold vast, ice-covered oceans, we need to be able to measure the forces at work. A new instrument designed and built at Lamont does just that.

  • The Damaging Effects of Black Carbon

    The Damaging Effects of Black Carbon

    Air pollution, both outdoors and indoors, causes millions of premature deaths each year. The deaths are mainly caused by the inhalation of particulate matter, especially black carbon. But black carbon not only has impacts on human health, it also affects visibility, harms ecosystems, reduces agricultural productivity and exacerbates global warming.

    A Prize-Winner Explains His Work

    Nicolás Young studies glaciers and ice sheets, and how they’ve changed in the past. His work earned him the Blavatnik Award for Young Scientists last fall, which came with a $30,000 prize. You can hear him talk about his research in this new video, produced by the Blavatnik Family Foundation.

  • Greenland Glaciers Retreating Faster than Any Time in Past 9,500 Years

    Greenland Glaciers Retreating Faster than Any Time in Past 9,500 Years

    A new study uses sediment cores to track the expansion and retreat of glaciers through time, and finds that they are retreating quickly and are more sensitive to temperature change than previously realized.

  • Shrinking Glaciers: A Chronology of Climate Change

    Shrinking Glaciers: A Chronology of Climate Change

    With new data, scientists can track back what glaciers did in the past, and how it is related to climate change. This provides a link to predict what could be happening in the next 100, 200, 500 years.

  • Exploring Beneath Earth’s Changing Ice Sheets

    Exploring Beneath Earth’s Changing Ice Sheets

    If just the West Antarctic Ice Sheet were to melt, it would raise global sea level by 6 meters. That’s more than a theoretical problem. West Antarctica is losing ice mass, and scientists are worried.

  • Melting Ice, Suntanned Rocks and an Award-Winning Postdoc

    Melting Ice, Suntanned Rocks and an Award-Winning Postdoc

    Nicolás Young was just named a winner of a 2015 Blavatnik Award for his work measuring ice sheets in changing climates of the past. His new projects are taking glacier tracking to the next level.
