    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

    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…

  • Fueled by Melting Glaciers, Algae Bloom Off Greenland

    Fueled by Melting Glaciers, Algae Bloom Off Greenland

    Iron particles catching a ride on glacial meltwater washed out to sea are likely fueling a recently discovered summer algal bloom off the southern coast of Greenland, according to a new study. Microalgae, also known as phytoplankton, are plant-like marine microorganisms that form the base of the food web in many parts of the ocean.…

  • Could Climate Change Shut Down the Gulf Stream?

    Could Climate Change Shut Down the Gulf Stream?

    In the 2004 disaster movie “The Day After Tomorrow,”, global warming accelerated the melting of polar ice, disrupting circulation in the North Atlantic Ocean and triggering violent changes in the weather. Could climate change shut down the Gulf Stream?

  • 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…

  • Radar Reveals Meltwater’s Year-Round Life Under Greenland Ice

    Radar Reveals Meltwater’s Year-Round Life Under Greenland Ice

    An improved technique developed by a graduate student at Lamont-Doherty Earth Observatory and her colleagues is making it possible to use airborne ice-penetrating radar to reveal meltwater’s life under the ice throughout the year.

  • State of the Arctic: Longer Melting Seasons, Thinning Sea Ice

    State of the Arctic: Longer Melting Seasons, Thinning Sea Ice

    The Arctic is warming twice as fast as the rest of the planet, and scientists are seeing the effects across ice and ecosystems. Lamont-Doherty Earth Observatory’s Marco Tedesco describes the changes underway.

  • In Greenland, Exactly Where Meltwater Enters the Ocean Matters

    In Greenland, Exactly Where Meltwater Enters the Ocean Matters

    In southern Greenland in summer, rivers have been streaming off the ice sheet, pouring cold fresh water into the fjords. A new study tracks where that meltwater goes—with surprising results.

Science for the Planet: In these short video explainers, discover how scientists and scholars across the Columbia Climate School are working to understand the effects of climate change and help solve the crisis.
