    With El Niño, Be Careful What You Wish for

    In Southern California, a strong El Niño usually signals rain. Given that California is now in the throes of a severe drought, it seems like that should be a good thing, even if it comes with risk of floods. But the reality of climate is more complex and counter-intuitive than it first appears.

    Making Agriculture Sustainable in One of India’s Poorest States

    Jharkhand, India is one of the nation’s poorest and most most food-insecure states, with over 45 percent of the population living below the poverty line. Can a research team devise sustainable ways to improve livelihoods, productivity and sustainable water use?

  • EPA Spilled, but Didn’t Dump, the Toxics That Ended up in Colorado’s River

    The short-term, expedient result of ignoring environmental impacts may be greater immediate profit for some, but the long-term impact is higher costs and lower profit, and many of those higher costs must be borne by all of us. Many of the companies that made the mess will be long gone before many of the bills…

    Learning from a River’s History to Prepare for the Future

    Researchers from eight universities, including Columbia University, are using tree ring and glacier analysis to reconstruct the climate history of the Missouri River Basin in order to give policymakers and water managers better decision-making tools to manage the river.

  • The Growing Groundwater Crisis

    The Growing Groundwater Crisis

    Groundwater is being depleted at alarming rates, not only in drought-stricken California, but around the world. When groundwater is depleted, it can take tens to hundreds of years to for it to reestablish its sustainable level, if at all. What can be done to avert a water crisis?

  • Revising the Toxic Substances Out-of-Control Act

    An unregulated chemical industry is an invitation for disaster. Fortunately, there is at least one place in America where regulation of toxic chemicals is taken seriously—California (of course).

    Subsurface Discovery Sprouts a New Branch on the Tree of Life

    Last week a study published in Nature pulled the veil on a branch of the bacterial tree of life that has evaded detection for nearly a century and a half. The study used cutting edge genome sequencing and savvy bioinformatics techniques to make this remarkable discovery.

    Viewing Melting Glaciers, Via Microscope and Moving Images

    Two women investigating climate change from different perspectives—Christine McCarthy, a geophysicist at Lamont-Doherty Earth Observatory, and Denise Iris, a multimedia artist from Brooklyn—had a chance to spend several days together recently. In the Rock Mechanics Lab at Lamont, where McCarthy works, and a nearby “cold room” chilled to the climate of an industrial freezer, they…

    From the Nile to the Sundarbans: the Undergraduate Capstones

    This spring, students in the Undergraduate Program in Sustainable Development presented innovative solutions to sustainability issues as part of their Capstone Workshop. Their clients ranged from the United States Military Academy at West Point to the Sabin Center for Climate Change Law.
