    Warmer Temperatures Drive Arctic Greening

    Using satellite images spanning decades, a new study has found that the northern tundra is becoming greener, as warmer air and soil temperatures lead to increased plant growth.

    Strange Bedfellows in the Climate Change Saga: Taiga to Tundra

    In the nine-hour drive on the great Dalton Highway to Toolik Field Station one starts out in the boreal forest, which is also called the “taiga,” but the forest eventually disappears. More accurately, trees disappear. Leaving Fairbanks, one drives through beautiful stands of spruce, birch, and aspen trees, but as one gets closer and closer…

    Strange Bedfellows in the Climate Change Saga: The Quest for the Arctic Wolf

    When you travel northbound on Alaska’s famous Dalton Highway heading toward the Arctic Sea, the northern edge of the world, you carry a radio to communicate with the enormous rigs that roar along the road, the giant trucks made famous by the History Channel’s Ice Road Truckers. Radio messages between truckers and non-truckers are simple…

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
