    How Did Africa’s Grasslands Get Started?

    Millions of years ago, vegetation across much of the world underwent a transformation as grasses with a new way of doing photosynthesis displaced previously dominant plants, shrubs and trees. A new study examines what got these plants started, and why they spread so far and wide.

    A new study has uncovered when and why the native vegetation that today dominates much of Australia first expanded across the continent.

    Study Finds Genetic Clues to How Plants Adapt to Climate

    Using supercomputers to analyze hundreds of thousands of genetic markers, scientists say they have found how a common weed uses its genetic code to adapt to changes in its environment such as cold and drought. The findings could help develop crops that are more adaptable to climate change.

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
