About AGU Fall Meeting

The American Geophysical Union (AGU) 2025 Fall Meeting will be held in New Orleans, L.A.,  Dec. 15-19, 2025. The AGU Fall meeting is the largest gathering of Earth and space scientists; over 25,000 attendees from over 100 countries will convene.

The theme is: “What’s Next for Science: Science has always been about the new. The now. The next. It’s what propels us, feeding our questions and inspiring our work. The constant question and answer form a rhythm, a cadence, a story. Science is a story. A story of infinite possibilities. A story of continuous discoveries. A story of hopeful solutions."
