    As Climate Stirs Arctic Sea Ice Faster, Pollution Tags Along

    A warming climate is not just melting the Arctic’s sea ice; it is stirring the remaining ice faster, increasing the odds that ice-rafted pollution will foul a neighboring country’s waters, says a new study.

    Christine McCarthy: A Cheerleader for the Physics of Ice

    Christine McCarthy, a geophysicist at the Lamont-Doherty Earth Observatory, scrunches blocks of ice between hunks of rock to study how ice behaves under pressure. Her work provides an important piece of the puzzle of how glaciers move, what makes them speed up, and how they are contributing to sea level rise as the climate warms.

    Iron Chemistry Matters for Ocean Carbon Uptake

    An interdisciplinary team of scientists has discovered that, contrary to general scientific belief, iron in nondissolved particle form can stimulate phytoplankton growth, and that the chemical form that particulate iron takes is critical to ocean photosynthesis.

    Adam Sobel: Preparing for the Next Big Storm

    Superstorm Sandy was a wake-up call for a lot of people in New York City, including Adam Sobel, who’s spent more than two decades studying the physics of weather and climate.

    Meltwater Lakes Existed Under Antarctic Ice in Ancient Times

    In recent years, scientists have discovered hundreds of lakes lying hidden deep beneath the Antarctic ice sheet. Now a team of researchers has found the remains of at least one sub-ice lake that existed when the ice was far more extensive, in sediments on the Antarctic continental shelf.

    In a Warmer World, Expect the Wet to Get Wetter, and the Dry, Drier

    As the world warms due to human-induced climate change, many scientists have been projecting that global rainfall patterns will shift. In the latest such study, two leading researchers map out how seasonal shifts may affect water resources across the planet.
