    Extreme-Weather Winters Becoming More Common in U.S., Study Shows

    This past July was Earth’s hottest month since record keeping began, but warming isn’t the only danger climate change holds in store. Recent years have seen a dramatic increase in the simultaneous occurrence of extremely cold winter days in the Eastern United States and extremely warm winter days in the Western U.S., according to a…

    How Safe is the Hudson? Scientists Test the River, Adirondacks to Ocean

    A team of scientists conducted an unprecedented health check of the entire Hudson River system, from its source to New York Harbor. This is what they found.

    How Does the Ocean Drive Weather and Climate Extremes?

    Lamont-Doherty Earth Observatory scientists Ryan Abernathey and Richard Seager are investigating how processes in the ocean create extreme weather and climate conditions over land.

    Construction in the Swamp

    Despite the miserable weather and ongoing rain, we constructed a wooden structure to hold the GPS receivers, solar panels and other electronic equipment between the three wells. We worked out how and where to mount the antennas and had parts made to accomplish it. Although I had to leave before it was completed, the team…

    Visit to a Different Delta: the Mississippi

    This summer I am in the Mississippi Delta in southern Louisiana helping to install an updated version of the compaction meters that we have in Bangladesh. The environment is quite different and we have arrived in the midst of an historic storm. Luckily for us the brunt of the storm is NW of us. So…

    Project Maps the Chemistry of the World’s Oceans

    Until recently, too little data existed about the distribution of trace elements and nutrients in the oceans to provide a global picture. In 2002, a group of scientists connected with Columbia University’s Lamont-Doherty Earth Observatory set out to fill those gaps.
