How the Alliance formed
The USAA-IPCC, hosted by the American Geophysical Union (AGU), was established in March 2025 by a network of universities and colleges that are registered observers of the IPCC.
It formed in response to federal decisions to end support for US participation in IPCC activities and to withdraw the US from the IPCC — just as the panel began preparing for its 7th Assessment Report (AR7). Limited US participation risked keeping recent US climate research out of AR7 and weakening the reports’ value for policymaking. The Alliance remains active — funding participants’ travel, nominating experts for special reports and expert meetings, facilitating reviews of draft reports, and supporting a community of practice.

What is the IPCC?
The Intergovernmental Panel on Climate Change is a United Nations body that assesses the science of climate change, its risks for people and the planet, and options for managing them. Its reports inform climate policy at every level of government and international negotiations under the UNFCCC.
Reports are written by international teams of hundreds of volunteer experts, nominated by governments and observer organizations and selected by the IPCC Bureau. Each goes through multiple rounds of open, transparent review before member nations accept it.
