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.

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

SeismoDome

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 at the American Museum of Natural History Hayden Planetarium, Holtzman and his collaborators will present one of these shows, the second installment of SeismoDome: Sights and Sounds of Global Seismology.

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.

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” of five oysters: Brook, Manny, Bronxy, Queeny and Stats.

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 factors driving the storm’s unusual ferocity, and how these played against human weaknesses. The book offers a primer on what drives storm systems, and what we know (and don’t) about their relation to warming climate. Sobel also looks into future weather, urban infrastructure and the politics of global climate change. He recently discussed some of his insights.

Sean Solomon, director of the Lamont-Doherty Earth Observatory and a geophysicist who has spent much of his career studying Earth’s neighboring planets as well as the Earth itself, will receive the National Medal of Science.

The Art and Science of Climate Change

At sea level, earlier flotation levels are clearly visible where the ice has been polished by the ocean’s constant movement.

This fall, the photographs of Sebastião Salgado provide the springboard for an ambitious program of panel discussions, lectures and film screenings addressing the urgent issue of climate change, at the International Center of Photography in New York City.

Max Cunningham, a graduate student at Lamont-Doherty, traveled to Costa Rica’s Mount Chirripó this past summer to test the idea that mountain glaciers carved the summit we see today. He and his colleagues hope to eventually pin down when Chirripó’s high-elevation valleys eroded into their current form. Check out a recap of their 2014 field season.
