Risk factors for the decade-long war in Sierra Leone must be addressed before its abundant natural resources can be equitably exploited for economic growth.

Imagine if each of the 4.3 million daily commuters on the New York City subway took an international flight. Now think of each of those people on flights spewing jet fuel emissions, guzzling canned soda from plastic airline cups and water from plastic bottles, tossing hotel toiletries into non-recycling bins, blasting hotel air conditioners, and…

Once you, as an outsider, spend considerable time in Mongolia, especially during Naadam and especially in the open Gobi steppe with people who still live as their ancestors did centuries ago, you will also begin to chase Chinggis Khaan.

We are a scientific team of 20 scientists currently aboard the R/V Langseth, acquiring seismic images of the Cascadia subduction zone. Through our work we hope to provide new insights on the position and structure of the plate boundary between the downgoing Juan de Fuca plate and the overlying North American plate.

On Thursday, June 28, the students in the Master of Public Administration in Environmental Science and Policy (MPA-ESP) program took a field trip to the Gowanus Canal in Brooklyn, NY. The trip was organized and led by Lamont Associate Research Professor Juerg Matter and Adjunct Professor of Environmental Health Sciences at Columbia’s Mailman School of…

Our sensors record the same seismic signals as the ocean bottom seismometers the R/V Oceanus deployed, and we will combine the data later. They can detect R/V Langseth signals up to 100 miles inland! This is something extraordinary, and difficult to believe until seen.

Watch a slide show featuring ongoing research by scientists at Columbia University’s Lamont-Doherty Earth Observatory, whose work around the globe is key to understanding past changes in the oceans and what is going on today.

After a day of coring on Tuesday, we decided to give our arms and backs a rest and collect water and plant samples. We take these samples so that we can characterize the chemical signatures of each plant type, and water from different parts of the system. Then, we can recognize those same signatures in…

The latest 2012 Climate Change Policy Tracker report released by Deutsche Bank Climate Change Advisors in partnership with the Columbia Climate Center shows that while current policies lead to emissions reductions, there is significant distance to go to reach “safe” levels of atmospheric greenhouse gases by 2020.
