  • The Indiana Jones of Climate Modeling

    The Indiana Jones of Climate Modeling

    By JD Capuano Benjamin Cook is a climate modeler at Lamont-Doherty Earth Observatory, part of the Earth Institute at Columbia University. Cook completed his Ph.D. in environmental science at the University of Virginia in 2007. He was among a select group of scientists awarded a Climate and Global Change Postdoctoral Fellowship by the National Oceanic…

    Making Room for Rivers: A Different Approach to Flood Control

    Over time, the U.S. Army Corps of Engineers, the federal engineering and construction agency, has spent over $123 billion on flood control infrastructure that hasn’t always adequately protected us. Now, with the devastation of the spring floods in the Midwest, some are calling for a new approach to flood control that makes room for our…

  • Rhone Glacier Finely Tuned to Climate Changes

    Rhone Glacier Finely Tuned to Climate Changes

    By chiseling hunks of stone from recently exposed bedrock near the edge of the Rhone Glacier, scientists were able to decipher the comings and goings of the ice over the past 11,000 years. That should help predict what will happen to glaciers in the warming world to come.

    The Uncertainties of Groundwater and Climate in India: An Interview with Chandra Kiran Krishnamurthy

    Since he arrived at the Columbia Water Center at its founding in 2008, Chandra Kiran Krishnamurthy has been unswervingly focused on two questions. First, how will groundwater depletion and climate change affect agriculture in India? And given the dire nature of the crisis, what can we do to help people adapt?

  • Young Citizens Lawsuit Seeks to Compel US Action on Climate Change

    A lawsuit filed in April on behalf of citizens too young to vote takes a novel approach in seeking to force the United States government to mitigate the most serious impacts of human-induced climate change. The petitioners argue that, in failing to address climate change, the federal government has abandoned its fiduciary responsibility to affirmatively…

  • Tree Rings Open Door on 1,100 Years of El Niño

    Tree Rings Open Door on 1,100 Years of El Niño

    Scientists have used tree-ring data from the American Southwest to reconstruct a 1,100-year history of the El Niño cycle that shows that, when the earth warms, the climate acts up. The research may improve scientists’ ability to predict future climate and the effects of global warming.

    R.I.P. La Niña

    La Niña, we hardly knew ye. This year’s iteration of the climate phenomenon nearly set records for strength and riled up world weather for nine months. Now it’s dead. What’s next?

  • Rising Seas Pushing Island Nations to the Brink

    Rising sea levels caused by global warming could displace millions of people worldwide who are living on low-lying coastlines, and it may prove fatal to some small island nations. At a conference at Columbia Law School, legal experts explored the implications for the people whose homelands could become uninhabitable within a matter of decades.

  • Squeezing the Last Drops out of Sicily

    Squeezing the Last Drops out of Sicily

    If you were to drive south from Palermo, Sicily toward Monreale, you would be ringed in by green mountains, the sparkling white of ancient and modern buildings and the azure Mediterranean Sea receding behind you. Continuing south through the island’s mountainous interior, you would pass verdant agricultural fields on your way past Corleone, the namesake…
