On every continent and ocean, Earth Institute field researchers are studying the dynamics of climate, geology, natural hazards and ecology, and their practical applications to modern problems. Below, a list of expeditions in rough chronological order. Work in and around New York City and the U.S. Northeast is listed separately toward bottom. Unless otherwise stated, projects originate with… read more
Using one of the most advanced atmospheric computer models available, scientists compared our expected future with a scenario in which ozone-depleting substances had never been regulated.
Excess carbon dioxide absorbed into the oceans is starting to have profound effects on marine life, from oysters to tiny snails at the base of the food chain. Our scientists explain the changes and what they are learning about ocean acidification in the past.
While national governments can set goals for combating climate change, many of the decisions that lead to action will come from business leaders. The new Columbia Center for Climate and Life helps them build from a foundation of science.
A new study uses sediment cores to track the expansion and retreat of glaciers through time, and finds that they are retreating quickly and are more sensitive to temperature change than previously realized.
Many experts at Columbia University’s Earth Institute are attending or closely watching the Paris climate summit. These include world authorities on climate science, politics, law, natural resources, national security, health and other fields, who can offer expert analysis to journalists. Here’s a guide to resources that journalists covering the summit can tap.
The United Nations Climate Change Conference, meeting in Paris from Nov. 30 to Dec. 11, brings together world leaders to craft a new international agreement to keep the average global temperature rise below 2°C by 2100. Here’s what you need to know about it.
A live-streamed international conference on El Niño takes place on Nov. 17 and 18 at the International Research Institute for Climate and Society.
We finished our work at the river transect. Now we had one more sample to collect. Alamgir had arranged for drillers at this new site, but they were delayed because of a knife fight between two villages over some property.
