    Sewage Still Plagues Hudson River

    People are swimming in the Hudson again, and while clumps of sewage rarely float by anymore, the water is not reliably clean, says a report released this week from the environmental group Riverkeeper. Four years of testing by Riverkeeper and Columbia’s Lamont-Doherty Earth Observatory, show recurring hot spots, especially after rain, when overwhelmed sewers divert…

    The Role of Drought in the Horn of Africa Famine

    Let’s get this out of the way. The current famine in the Horn of Africa isn’t caused by drought. Rather, a complex mix of societal and political factors created a dangerous situation.

    Maintaining the Superiority of NYC’s Drinking Water

    The Year of Drought and Flood

    It seems that this year the world is experiencing a crisis of both too little water and too much. And while these crises often occur simultaneously in different regions, they also happen in the same places as short, fierce bursts of rain punctuate long dry spells.

    Somali Drought; Harbinger of Hard Times

    For all its problems, Southern California has been a wonderful home for a lot of people over the past 100 or so years. It has nice beaches, good roads, plenty of places to eat, and, for now, a reliable supply of drinking water. Now imagine the L.A. riots had spread across the entire region, plunging…
