    Robin Bell Goes to Washington to Testify About Melting Ice Sheets

    At a hearing of the House Science Committee on Thursday, she’ll explain her research and why changing polar ice matters to everyone in America and around the world.

  • Melting of Himalayan Glaciers Has Doubled in Recent Years

    Melting of Himalayan Glaciers Has Doubled in Recent Years

    A new study is the latest and perhaps most convincing indication that climate change is eating the Himalayas’ glaciers, potentially threatening water supplies for hundreds of millions of people across much of Asia.

  • Why Cry for the Cryosphere?

    Why Cry for the Cryosphere?

    A new book paints a daunting and detailed picture of earth’s natural ice under threat, and explains why what happens in the Arctic doesn’t stay in the Arctic.

  • 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.

    Photo Essay: Melting Greenland, Up Close

    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.

  • Glacier Researchers Gather at IPCC Meeting in China

    Glacier Researchers Gather at IPCC Meeting in China

    Ever wonder how thousands of scientists come together to author the world’s most authoritative report on climate change? A lead author brings us inside one working group.

  • Glacial Geoengineering: The Key to Slowing Sea Level Rise?

    Glacial Geoengineering: The Key to Slowing Sea Level Rise?

    A new proposal suggests building underwater walls to protect glaciers from warm water. Here’s how it might work.

  • Researchers Model Differences in East Coast Sea Level Rise

    Researchers Model Differences in East Coast Sea Level Rise

    For years, scientists have been warning of a so-called “hot spot” of accelerated sea-level rise along the northeastern U.S. coast. But accurately modeling this acceleration as well as variations in sea-level rise from one region to another has proven challenging. Now new research offers the first comprehensive model for understanding differences in sea level rise…

  • The Glaciers Are Going

    The Glaciers Are Going

    Glaciers around the world have retreated at unprecedented rates and some have disappeared altogether. The melting of glaciers will affect drinking water supplies, water needed to grow food and supply energy, as well as global sea levels.
