    Unplanned Time in Dhaka

    Due to the speed at which the two Scotts were able to repair the compaction meter, I found myself with two extra days in Dhaka. Besides numerous quickly planned meetings, I got to see the celebration of the arrival of Bengali Spring and the growing protest movement against the light sentence for Islamists convicted of…

    Faculty Profile: Naresh Devineni

    Naresh Devineni will be teaching a course on the Management and Development of Water Systems as part of the new Certificate in Sustainable Water Management. In this interview, conducted by Nick Turchak, Naresh elaborates on his research topics in Hydro-climatic Data Analysis and Modeling, Water Resources Management and Risk Assessment.

  • Bogged Down in Alaska

    For thousands of years Arctic peat bogs have soaked up atmospheric carbon like a giant sponge. But as the poles warm, the arctic bogs will decay and expel billions of tons of carbon back into the air—or will they? A warmer climate might actually improve growing conditions in the bogs, allowing them to take up…

    Aquanauts Take on New York Water Issues

    Working with engineering PhD candidate Rob Elliott, we imagined a green roof and blue roof system that would serve as a space for environmental education and student wellness, the culmination of a semester spent examining and taking action on stormwater management issues in New York City.

    Smaller Colorado River Projected for Coming Decades, Study Says

    Some 40 million people depend on the Colorado River Basin for water but warmer weather from rising greenhouse gas levels and a growing population may signal water shortages ahead.

    Clues from Last Ice Age May Hint at Drying Ahead for Some Regions

    In the spectacular collapse of ice sheets as the last ice age ended about 18,000 years ago scientists hope to find clues for what regions may grow drier from human caused global warming. In a talk Thursday at the American Geophysical Union’s annual meeting, Aaron Putnam, a postdoctoral scholar at Lamont-Doherty Earth Observatory, painted a…
