    Think Globally, Act Locally: Climate Adaptation in Action

    Across Indonesia, several effective climate adaptation actions on local levels are underway. These actions serve as a reminder of the important change that starts with a community of dedicated individuals.

  • Climate News Roundup – Week of 8/2

    Last Week: Todd Stern says the US bargaining position for Cancun remains unchanged, climate change prolongs interior Alaska growing seasons, China reports improved energy efficiency this quarter, diplomats ponder temporarily extending the Kyoto Protocol, and the biggest ice island for 48 years breaks off of a Greenland Glacier.

    Global Population Growth and Water Scarcity Q&A

    Russell Sticklor with the Wilson Center’s Environmental Change and Security Program in Washington, DC. recently contacted me requesting my thoughts on a number of issues for an article he is writing on global population growth and water scarcity for the magazine, Outdoor America. I thought some of the comments might be interesting to our blog…

  • Climate News Roundup — Week of 7/26

    In an effort to save fuel, money, and reduce carbon emissions, modern cargo ships are reducing their speeds from near 25 knots to as low as 12 or 13 knots, or about 14 mph. Super-slow steaming, as the practice is known, reduces the speed of cargo boats to less than that of 19th-century clipper ships.…

    Scary Water Study from the NRDC

    A fascinating and frightening recent study from the National Resources Defense Council unveiled serious threats to water sustainability in the United States over the coming decades. In an era of rapidly unfolding climate change, the Council’s research found that more than 1,100 counties, or one third of all counties in the lower 48 states, face…

    Amazonians Have Shot at Reducing Greenhouse Gases, Says Study

    The huge Brazilian Amazon state of Mato Grosso will cut its emissions of greenhouse gases by more than half if it sticks with current plans to reduce deforestation substantially by 2020, says a new study. The research, published this week in the Proceedings of the National Academy of Sciences, uses 105 years of historical data…

    A final note (for now) on the expedition to recover ice cores from the top of Puncak Jaya in Papua, Indonesia: the cores arrived safely on Thursday, July 22, at Ohio State University’s Byrd Polar Research Center, and are now in a special freezer. In coming months, the team hopes to extract and interpret climatic…

AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana. This year’s theme—Where Science Connects Us—puts in focus how science depends on connection, from the lab to the field to the ballot box. Once again, Lamont-Doherty Earth Observatory and Columbia Climate School scientists, experts, students, and educators are playing an active role, sharing our research and helping shape the future of our planet. #AGU25 Learn More
