  • Switchyard 2012: Climate Change in the Arctic

    Arctic summer sea ice is declining rapidly: a trend with enormous implications for global weather and climate. Now in its eighth year, the multi-year Arctic Switchyard project is tracking the Arctic seascape to distinguish the effects of natural climate variability from human-induced climate change. The University of Washington is leading the project. A) The Canadian…

    Drill Down into Africa Soils Projects

    The Africa Soil Information Service has upgraded its website with a new layout, easier navigation and updates on project activities. A growing set of features provides information for managing soil and land in Africa, including an interactive map tool that allows you to choose layers and areas of interest that can be downloaded.

    Healthy Oceans: Charting A New Course

    Leading up to Rio+20, on April 25th the United Nations hosted “Healthy Oceans: Charting A New Course,” a panel discussion which brought together a range of experts to discuss the fate of the world’s oceans and what can be done to protect them.

    New Book Teaches How to Think like a Geologist

    Geologists really do see the world differently, whether it’s imagining the ancient processes that give rise to mountains or untangling the complexities that produce weather. A new book, co-edited by Lamont scientist Kim Kastens, explores the ways that geologists analyze and understand the earth system, and offers tips for those seeking to better understand it.

  • Fossil Teeth, Traces of Climate & Evolution

    Fossil Teeth, Traces of Climate & Evolution

    From fossil teeth to carbon traces of plants in the soil, scientists are studying how changes in climate may have influenced early human evolution in Africa. Researchers from around the world gathered for a symposium held recently at the Lamont-Doherty Earth Observatory. Watch the videos.

  • Dead Plants Strengthen Beliefs in Global Warming

    Dead Plants Strengthen Beliefs in Global Warming

    Subtle stimuli in the environment exert a strong influence on the way we think about global warming. The notion that surrounding objects unconsciously influence our thoughts and behavior is of interest to individuals who are interested in developing strategies to promote sustainable behavior.

    Plankton Fishing in the Bering Sea

    As Discovery Channel fans know, the Bering Sea supports one of the world’s most productive fisheries, accounting for more than 50 percent of U.S. fish and shellfish catches. The goal of our study is to understand how climate change is impacting phytoplankton, and ultimately the Bering Sea ecosystem.

    Did Climate Change Shape Human Evolution?

    “The use of stone to make stone that can cut flesh is important,” Richard Leakey said. “We’re not empirical things, we’re thinkers. … What was it that triggered that response?”

    Spring Sprang Early: Should We Worry?

    While studies do show that flowers and other plants are blooming earlier on average because of warming trends, this year’s early fireworks were “certainly well within the realm of experience for the species native to this area,” says Robert Naczi of the New York Botanical Garden.
