Global companies with long supply chains could do a much better job of managing climate disaster risk, according to a recently published study from Masahikio Haraguchi and Upmanu Lall, researchers at the Columbia Water Center. According to the study, published in the International Journal of Disaster Risk Reduction, even as the impact of natural hazards [...]

According to the World Water Management Institute, over one-third of the human population is affected by water scarcity. Advances in physical understanding, its applications, and the study of our environment and bio-mimicry help us develop more effective ways to fight freshwater scarcity around the world.

To protect a river, you must preserve its headwaters. Agricultural development is warming streams at the headwaters of the Xingu River, in Mato Grosso, Brazil. Rising temperatures have local impacts that could cascade into regional changes, highlighting the importance of responsible land use outside of protected areas.

This fall, the photographs of Sebastião Salgado provide the springboard for an ambitious program of panel discussions, lectures and film screenings addressing the urgent issue of climate change, at the International Center of Photography in New York City.

This experience taught us not only about climate modeling, quantitative research and analysis, but also about the dynamic process of working with a client and with a team. After months of hard work, our team presented our findings to fellow students and faculty at Columbia and to our clients at West Point. The project has blossomed into continued collaboration between Columbia and West Point—including additional capstone projects in the spring semester.

Climate scientist William D’Andrea of the Lamont-Doherty Earth Observatory asked young scientists attending a symposium last October, “What do you wish everyone knew about climate change?” He turned the responses into this video, which covers the topic pretty well.

Photo Essay: Studying Fracking’s Effects, Up Close and Personal

Geochemist Beizhan Yan of Columbia University’s Lamont-Doherty Earth Observatory is studying the environmental effects. His vest carries sensors to record air quality and noise levels as  he walks.

Ten years ago, hydraulic fracturing barely existed. Today 45,000 fracked wells produce natural gas, providing energy for millions of homes and businesses, and nearly a quarter of the nation’s electricity. But scientists are far behind in understanding how this boom affects people near wells. Geochemists Beizhan Yan and James Ross of Columbia University’s Lamont-Doherty Earth Observatory are trying to fill in this gap.

Five hundred utilities in the U.S. provide drinking water with unsafe levels of arsenic, the Environmental Protection Agency says. But how many people are getting too much arsenic in their water is much less clear, according to a study conducted in part by the Columbia Water Center.
