But an agroecologist? “Agroecologists always feel a little outcast when working on development issues,” says Fabrice De Clerck, an Earth Institute Fellow with the…
The Natural Disaster Hotspots report released earlier this year showed that the U.S. Gulf Coast is among the world’s most at-risk regions in terms of human mortality and economic loss due to storms like Katrina and Rita. The study, which was produced by researchers from the Center for Hazards and Risk Research, The International Research…
Scientists at Columbia University’s Lamont-Doherty Earth Observatory and the University of Illinois at Urbana-Champaign have ended a nine-year debate over whether the Earth’s inner core is undergoing changes that can be detected on a human timescale. Their work, which appears in the August 26 issue of the journal Science, measured differences in the time it…
New databases give researchers a look into processes inside the Earth’s mantle
New images suggest that the Earth’s lower oceanic crust is generated from multiple magma sources
There was little rest this summer for students in Columbia’s Master of Public Administration Program in Environmental Science and Policy, who spent the last few months sharpening their knowledge of management and policy issues through the Workshop in Applied Earth Systems Management. Fifty-eight Masters’ candidates gathered in five project teams to design a detailed operational…
Using a computer model she built herself, Debra Tillinger, an environmental science major, came up with a prediction as to how much better New York City’s sewage system would function if plant-covered roofs throughout the city slowed the flow of rainwater to the sewers. Tillinger’s research, which was part of her theses project for her…
