    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.

    Vegetation Can Strongly Alter Climate and Weather, Study Finds

    A new analysis of global satellite observations shows that vegetation can powerfully alter atmospheric patterns that influence climate and weather.

    Richard Seager Sees Hand of Climate Change in Drought

    California’s wet and snowy winter brings welcome relief from a years-long drought that has challenged the state’s water supply and agricultural system. But climate scientist Richard Seager of Lamont Doherty Earth Observatory offers words of caution: Remember what happened, because it will happen again.

    This past winter, reporters from the New York Times went along for the ride with scientists from the Lamont-Doherty Earth Observatory as they flew their mission of discovery over Antarctica.

  • Researchers Model Differences in East Coast Sea Level Rise

    Researchers Model Differences in East Coast Sea Level Rise

    For years, scientists have been warning of a so-called “hot spot” of accelerated sea-level rise along the northeastern U.S. coast. But accurately modeling this acceleration as well as variations in sea-level rise from one region to another has proven challenging. Now new research offers the first comprehensive model for understanding differences in sea level rise…

    Testing Links Between Extreme Weather and Climate Change

    A new four-step “framework” aims to test the contribution of climate change to record-setting extreme weather events.

    Water Is Streaming Across Antarctica

    In the first such continent-wide survey, scientists have found extensive drainages of meltwater flowing over parts of Antarctica’s ice during the brief summer. Many of the newly mapped drainages are not new, but the fact they exist at all is significant; they appear to proliferate with small upswings in temperature, so warming projected for this…

    Pratigya Polissar Sees Landscapes Changing Through a Microscope

    The word fossils typically conjures images of T-Rexes and trilobites. Pratigya Polissar thinks micro: A paleoclimatologist, he digs into old sediments and studies molecular fossils—the microscopic remains of plants and animals that can tell us a lot about what was living in a particular time period.
