    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.

    How to reduce weather risk (and make a little green)

    People understand that weather can affect certain markets — especially energy prices and other commodities — but its impact on portfolios more broadly might surprise. Just last week, a new study was released that estimated $485 billion of annual weather-related economic impact in the United States alone.

    Can Big Earthquakes Disrupt World Weather?

    The recent earthquake in Japan shifted the earth’s axis by half a foot. You may be wondering if that’s enough to change earth’s weather. No, not really, says Jerry McManus, a climate scientist at Columbia’s Lamont-Doherty Earth Observatory. Earthquakes unleash a tremendous amount of energy, but not enough to upset the energy balance of earth’s…
