    Hurricane Histories and Carbon Mysteries

    The Bahamas might be a vacation destination for most people. But for us, they represent an excellent site to study several different questions about past, present and future climates.

    Behind the Expected Quiet 2015 Hurricane Season

    On May 27, 2015, NOAA officially announced a likely below-normal Atlantic Hurricane season is coming up. The range for the possible numbers of major hurricanes is 0-2. What are the reasons behind it? How precise are these numbers?

    Tapping into Earth’s Secret History

    In a study published last week, Lamont post-doctoral scholar Heather Ford and coauthors used 4 million-year-old fossils from the Pliocene to reconstruct the physical features of the Pacific Ocean that would have shaped the environment during a critical juncture in Earth history.

    H. James Simpson; Tracked Pollutants in the Hudson and Far Beyond

    H. James Simpson, a geochemist who pioneered important studies of water pollutants in the Hudson River and abroad, died May 10. He had been affiliated with Columbia University’s Lamont-Doherty Earth Observatory for 50 years. The cause was Parkinson’s disease, said his family; he was 72.

    World’s Oldest Unused Stone Tools Found (So They Say)

    Last week, it was announced that scientists had found the world’s oldest stone tools, in Kenya, dated at 3.3 million years. The precise dating of the tools was made possible by Chris Lepre and Dennis Kent of Lamont-Doherty Earth Observatory, who used periodic reversals in earth’s magnetic field to nail the timing. Now, in a…

    Was Hurricane Sandy the 100-Year Event?

    Recent research suggests that Sandy may have been much more likely than previously believed.

    Distilling Art from the Figures of Science

    Any researcher can attest to the fact that a scientific figure is worth more than a thousand words. Rarely do we take a step back to consider the inherent artistry in the figures created to convey the science.

    Study Reveals Microbes’ Hidden Role in Fertilizing Oceans

    Surprisingly little has been known about how phosphorous, an essential nutrient, cycles through the oceans. A new study has broken through some of this mystery, by showing the hidden role that the oceans’ tiniest creatures play.
