AI Insight
The American Geophysical Union (AGU) has announced six new Editors-in-Chief who will begin their terms in 2027 across various AGU publications, including AGU Books, Community Science Exchange, JAMES, JGR: Biogeosciences, JGR: Oceans, and Water Resources Research. The new editors were selected through an open call process managed by dedicated search committees and will succeed outgoing editors who served terms primarily from 2020-2026. The appointments span institutions across the United States, India, Italy, and France, representing diverse geographic and scientific expertise.
Why it matters
These editorial appointments will shape the direction and quality of major Earth and space science publications that influence research priorities, disseminate scientific findings, and guide the global geoscience community. The diversity of the new editorial leadership may broaden perspectives and enhance the international reach of AGU's scientific publications.

AGU Publications’ Editor-in-Chief searches are conducted through an open call and managed by dedicated, journal-specific Search Committees. The composition of each committee follows a defined process and coordination between the Publications staff team and the Publications Committee. Search Committees make their recommendations to the Publications Committee, which ensures diversity and balance across all searches conducted during the year. The Publications Committee then forwards its final recommendations for a reputation review performed by leaders of the Board, Council, Leadership Development/Governance Committee, and staff partners. We extend our sincere thanks to all these colleagues for their invaluable contributions to this important process.
