    Rainfall patterns in the Sahara during the six-thousand-year “Green Sahara” period have been pinpointed by analyzing marine sediments, according to new research.

    What is now the Sahara Desert was the home to hunter-gathers who made their living off the animals and plants that lived in the region’s savannahs and wooded grasslands 5,000 to 11,000 years ago.

    Natural disasters have caused the deaths of hundreds of thousands of people worldwide with associated costs of hundreds of billions of dollars in property damage. Providing timely warnings of damaging ground-shaking from earthquakes and the imminent arrival of tsunamis is an ongoing challenge. Networks of instruments developed in recent years by researchers at the Lamont-Doherty Earth Observatory and elsewhere have improved our ability to provide those predictions for vulnerable populations. A new pilot program led by Lamont aims to make those warnings earlier and more accurate.

    When summer temperatures rise in Greenland and the melt season begins, water pools on the surface, and sometimes disappears down holes in the ice. That water may eventually reach bedrock, creating a slipperier, faster slide for glaciers. But where does it go once it gets there, and what happens to it in the winter? A new study helps answer these questions.

    Across the Lamont-Doherty Earth Observatory campus, scientists are exploring undersea volcanoes, monitoring coastal erosion along hard-to-reach shorelines, and studying the movement of sea ice – all in real time. By loading drones with high-tech instruments and using satellites and undersea cables that are interacting with sensors in some of the most remote locations on Earth, they are uncovering the secrets of our planet.
