    Warming Streams Have Cascading Impacts in the Amazon

    To protect a river, you must preserve its headwaters. Agricultural development is warming streams at the headwaters of the Xingu River, in Mato Grosso, Brazil. Rising temperatures have local impacts that could cascade into regional changes, highlighting the importance of responsible land use outside of protected areas.

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
