    AGU 2014: Key Events from The Earth Institute

    Scientists at Columbia University’s Earth Institute will present important talks at the Dec. 15-19 meeting of the American Geophysical Union, the world’s largest gathering of earth and space scientists. Here is a journalists’ guide in rough chronological order.

  • Why are Past Surface Temperatures and CO2 Concentrations Important?

    Why are Past Surface Temperatures and CO2 Concentrations Important?

    By burning fossil fuels for heating, electricity, transportation and other purposes, humans add CO2 to the atmosphere. Yet, by comparing ways in which the Earth’s temperature, CO2 concentration, sea level and ice sheets have changed in the past, we are able to learn valuable lessons about the climate system of today and tomorrow.

    This Bird Flies South for the Winter

    Migrating south in the winter is a behavior that Antarctic scientists share with many species of birds, although the scientists fly just a bit further south. For the IcePod team it was time to join the migration so they could test their equipment in the most challenging environment the Earth has to offer.

  • Sounds of Seismology

    Sounds of Seismology

    Lamont-Doherty Earth Observatory scientist Ben Holtzman grew up discovering science through interactive exhibits in San Francisco’s Exploratorium and now provides a similar experience for others. Holtzman designs immersive shows that allow people to experience what earthquakes and seismic waves look and sound like as they move through and around the Earth. On Monday, November 17th…

    Photo Essay: A Day in the Life of the Hudson River

    Once a year, Piermont Pier becomes a field station, and local students, a team of environmental investigators. On Tuesday, scientists at Lamont-Doherty Earth Observatory led students through a series of field experiments designed to teach them more about the Hudson River.

    Eco-Theater Engages Visitors at Lamont-Doherty’s Open House

    Visitors to Lamont-Doherty Earth Observatory’s open house on Oct. 11 could tune in to a performance of “Salty Folk” by Superhero Clubhouse, a collective of artists and environmental advocates. Created by Jeremy Pickard and Nate Weida, the play uses music and humor to illustrate the history and importance of New York Harbor through the “eyes”…

    Volcanic Plumbing at Mid-Ocean Ridges Goes Far Deeper than Thought

    New pictures in the journal Nature Geoscience may help resolve a debate about how new crust forms at mid-ocean ridges where earth’s tectonic plates are slowly pulling apart.

    Eye on the Storm

    Atmospheric scientist Adam Sobel is author of the new book “Storm Surge: Hurricane Sandy, Our Changing Climate and Extreme Weather of the Past and Future.” Sobel was one of the first researchers to explain to media and the public what might be brewing, before the storm hit. In the aftermath, he looked closely at the…

  • A Scientist Who Traveled the World to Study the Forest, and the Trees
