Paul Richards Wins Seismological Society of America’s Reid Medal
In a research career spanning more than four decades, Paul Richards, a seismologist at Lamont-Doherty Earth Observatory, has helped uncover Earth’s inner structure and advanced techniques for detecting nuclear explosions to ensure that bans on nuclear testing can be enforced. Richards will receive the Seismological Society of America’s Harry Fielding Reid medal at its annual…

New Book Explores Link Between Climate and Ocean Currents
Wallace Broecker is a climate scientist at Lamont-Doherty Earth Observatory who has helped shape our understanding of how the ocean moves heat around the globe, and how this so-called “great ocean conveyor” can switch the climate to a radically different state. Many scientists used to think that only periodic changes in earth’s orbit—so-called Milankovitch cycles–…

Climate, Fires and Birds: How is the Tundra Changing?
Natalie Boelman is an ecologist at Lamont-Doherty Earth Observatory who studies the effects of climate change on organisms throughout the food chain. She first visited the Alaskan Arctic in 2001, and will return to the North Slope this spring and summer to continue a wildfire-mapping project and to set up a field study that will…

Tundra, Microbes and World Climate
O. Roger Anderson is a microbiologist at Lamont-Doherty Earth Observatory who studies bacteria, amoebas, fungi and other microorganisms. Lately he has been thinking about how tiny organisms that inhabit the vast northern tundra regions could contribute to changing climate, since, like humans, they breathe in oxygen and breathe out carbon dioxide. Recently, Anderson found a…

Almost No One Is Being Completely Unreasonable
Peter deMenocal is a marine geologist who studies sea-bottom sediments for clues to past climates. Among other things, he has found evidence that previous civilizations suffered and fell during sudden climate swings. He also teaches an undergraduate class in basic earth sciences at Columbia University. As the Copenhagen summit headed for its second week, journalist…

Farming in Future Climates
Agronomist Pedro Sanchez has helped many regions of the world boost food production through better use of nutrients, and now heads the Earth Institute’s Tropical Agriculture and Rural Environment Program. He is at the Copenhagen summit looking for support to build a global soil map that will help farmers work more efficiently in the future.…

You Can Ignore Polar Bears, But Not People
As the Copenhagen summit prepared to open, we asked geophysicist and social scientist John Mutter to talk about the prospects. While at sea, Mutter investigates the workings of deep ocean floors; on land, he directs the Earth Institute’s Ph.D. in Sustainable Development and works to focus science on humanitarian causes. Among other things, he pinpointed…

Polar Survival a Century Ago: Good Planning, or Just Good Weather?
Before airplanes and satellite phones, polar exploration was a more dangerous undertaking than it is now. Many who set out for the frozen ends of the earth did not come back. Norwegian explorer Fridtjof Nansen and British explorer Ernest Shackleton were some of the few who brought their entire crews home safely. Nansen began his…
