  • Global Warming’s ‘Missing’ Heat: It May Be in the Indian Ocean

    Global Warming’s ‘Missing’ Heat: It May Be in the Indian Ocean

    Since the late 1990s, global warming has stabilized, even as greenhouse gases have risen. That defies simple models that say the temperature should keep going up. A team of oceanographers now says they know where the missing heat has gone.

  • Was Hurricane Sandy the 100-Year Event?

    Was Hurricane Sandy the 100-Year Event?

    Recent research suggests that Sandy may have been much more likely than previously believed.

  • Bad Ozone Days in Western U.S. Linked to Pacific Weather

    Bad Ozone Days in Western U.S. Linked to Pacific Weather

    A new study shows that ozone pollution in the western United States can be increased by La Niña, a natural weather cycle at the surface of the Pacific Ocean. The finding is the first to show that the La Nina-El Nino cycles directly affects pollution.

  • Smooth Sailing Back to Tasmania

    Smooth Sailing Back to Tasmania

    After a surprisingly smooth crossing of the Southern Ocean, with favorable winds we arrived back in Hobart, Tasmania. The weather maps show that we just got ahead of another big storm system.

  • Taking a 4,000-Meter-Deep Profile of Antarctic Waters

    Taking a 4,000-Meter-Deep Profile of Antarctic Waters

    In addition to understanding potential pathways for “warmer” circumpolar deep water to reach the ice shelf, we are also measuring what the structure and properties of the water column are and determining if there is already warmer water on or near the continental shelf that could already interact with the glaciers of East Antarctica today.

  • A Climate Battle Cry for Earth Day

    A Climate Battle Cry for Earth Day

    A group of 17 renowned scientists from around the world are appealing for dramatic action to forestall the worst effects of climate change, issuing an “Earth Statement” that calls for a world powered with zero carbon emissions by mid-century.

  • Mapping the Seafloor

    Mapping the Seafloor

    One of the goals of this expedition is to investigate if water from the Southern Ocean with temperatures above the melting point of glaciers could reach the glaciers in East Antarctica, and if there are any obstacles on the seafloor of the shelf that impact the ability of such water to reach the glaciers and…

  • Lamont-Doherty Strategic Plan

    Lamont-Doherty Strategic Plan

    Lamont-Doherty Earth Observatory has been a leader in the study of our planet since its founding 65 years ago. Today, Observatory scientists continue the institution’s long tradition of addressing important questions in the Earth and planetary sciences. 

  • In a Melting Iceland, Drilling Deep to Stem Climate Change

    In a Melting Iceland, Drilling Deep to Stem Climate Change

    Iceland is pioneering a new technology to deal with climate change. Its Hellisheidi geothermal power plant, the world’s largest, hosts arguably the world’s most advanced program to capture and lock away globe-warming carbon dioxide.
