Tree Rings, Ecology and Culture in Mongolia
“How do you know when you are in wilderness? When you have walked beyond where most people walk, when you have left the road … when the easiest route to walk is not a path tread by people but rather the path tread by wolves, moose and deer.”

Atmospheric Scientists Win Early Career Awards
Two scientists at Lamont-Doherty Earth Observatory have been recognized for early-career achievement in the atmospheric sciences by the American Geophysical Union (AGU), the world’s largest earth-sciences organization. Tiffany Shaw, 31, is a physicist who uses computer models and mathematical equations to study the basic dynamics of the atmosphere and climate, for instance, how the jet…

The Year of Drought and Flood
It seems that this year the world is experiencing a crisis of both too little water and too much. And while these crises often occur simultaneously in different regions, they also happen in the same places as short, fierce bursts of rain punctuate long dry spells.

Rhone Glacier Finely Tuned to Climate Changes
By chiseling hunks of stone from recently exposed bedrock near the edge of the Rhone Glacier, scientists were able to decipher the comings and goings of the ice over the past 11,000 years. That should help predict what will happen to glaciers in the warming world to come.

Tree Rings Open Door on 1,100 Years of El Niño
Scientists have used tree-ring data from the American Southwest to reconstruct a 1,100-year history of the El Niño cycle that shows that, when the earth warms, the climate acts up. The research may improve scientists’ ability to predict future climate and the effects of global warming.

Measuring Gravity From a Moving Aircraft Requires a ‘Gravi-God’!
From: Joël Dubé, Engineer/Geophysicist at Sander Geophysics, OIB P-3 Gravity Team One of the instruments used in Operation IceBridge (OIB) is an airborne gravimeter operated through a collaboration between Lamont Doherty Earth Observatory of Columbia University and Sander Geophysics of Ottawa, Canada. People from other instrument teams have been heard to call it a gravity…

Switchyard Project: Melting Ice, a Fresher Arctic
The freshwater content of the Arctic Ocean is increasing as the Earth’s climate warms. Chemical analysis indicates that the source is both melting ice and the Pacific Ocean.

Earth, Water and Sky –A Conversation with Pierre Gentine, a new Columbia Water Center Scientist
Columbia Water Center welcomes Pierre Gentine, Assistant Professor of Applied Mathematics at Columbia University’s School of Engineering and Applied Science, as an affiliate researcher. Pierre’s groundbreaking research on the way soil moisture interacts with the atmosphere has implications for many of CWCs initiatives—from developing more efficient irrigation systems, to water resource management, to understanding floods.…
