The preeminent conference for the advancement of Earth and space sciences, the AGU (American Geophysical Union) Fall Meeting draws more than 25,000 attendees from over 100 countries each year to share research findings and identify innovative solutions to complex problems. Organized around the theme “Science Leads the Future,” this year’s AGU Fall Meeting will take place in Chicago and online on December 12 - 16.

Among those researchers will be 15 co-authors of oral and poster presentations, and conveners of conference sessions, who are core members or faculty affiliates of the MIT Joint Program on the Science and Policy of Global Change. Listed below—links to complete abstracts, names of Joint Program co-authors or conveners (in bold for lead authors or conveners)—their presentations and sessions span multiple Joint Program research focus areas, including Earth systems, managed resources, energy transition, and multi-sector dynamics.

Categorized by primary research focus area, these linked presentations and sessions highlight recent findings by Joint Program researchers and their co-authors on tools and pathways to assess and reduce regional and global risk.
