    Climate News Roundup: Week of 6/12

    California re-embraces carbon market, Reuters, June 13 After a court ordered California to consider alternatives to cap and trade, the Air Resources Board published a 120-page policy analysis on Monday, examining five approaches to cut emissions, including a carbon tax, direct regulation of power plants and big factories, and a cap-and-trade system. The report concludes…

    To the tip of the Andes

    In the semi-arid Andes, glaciers store water and control the runoff of mountain rivers. They feed water to big cities such as Lima and Arequipa and irrigate the surrounding lowlands. But as the planet warms, mountain glaciers in the tropics are receding steadily. Despite their paramount importance, we don’t know the scale and the rate…

  • SEDAC Data Featured via New Discovery Tool

    Gridded Population of the World (GPW), the Environmental Performance Index (EPI), and the Last of the Wild/Human Footprint collection are just a few of the many SEDAC data holdings that can now be found via the improved search interface Reverb—NASA’s Next Generation Earth Science Discovery Tool.

    New Water-Smart Communities Prepare For a Water Scarce Future

    A recent study by the Stockholm Environment Institute warns that the American Southwest is exhausting its water resources, and if water use isn’t reduced, “The cumulative water shortfall for the Southwest for the next century, without adaptation, will be 1,815 million acre feet” due to population and economic growth. Climate change will, of course, make…

    Toxic Waters in the Gilded State

    To those who have never been, the Golden State is known for luxurious palm tree-lined avenues, sun-drenched beaches, and picturesque mountains. But not all parts of California were created equal. The state’s San Joaquin Valley hosts a scene entirely different from the images of Malibu beaches depicted in travel brochures. It is the non-glittering core…

    Hands-on Earth Science Book Wins Education Award

    A new book of puzzles on earthquakes, weather, climate and hydrothermal vents has been recognized for distinguished achievement by the Association of Educational Publishers. Using real-world scientific data, Earth Science Puzzles lets students practice key earth science skills and concepts such as locating an earthquake or figuring out what controls the amount of water flowing…

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
