    “Much of sustainable development is about where the world is headed in the future, anticipating the changes that are to come and evaluating the choices that we have available to address them. But understanding how natural and socioeconomic systems will change in the future, including the climate system, often requires that we look to the…

    A video profile of the Lamont-Doherty Core Repository—the world’s largest collection of deep sea sediments, some as old as 100 million years. The 19,000 cores, largely collected by Lamont’s own research vessels, are a central resource for the global scientific community, which uses them for studies of earth’s past and current environment, especially in regard…

    A new method for detecting big landslides is allowing scientists to understand the dynamics of these elusive events almost instantly, without traipsing to remote mountains or scrambling up rugged peaks months, or even years, later. In a recent study in the journal Science, Göran Ekström and Colin Stark, geophysicists at Columbia University’s Lamont-Doherty Earth Observatory,…
