#1. Foreword by Simon Wallis, President of JpGU (2025-2026)
One of the summer events on the earth and planetary science calendar is the Asia Oceania Geosciences Society (AOGS) annual meeting. Like our own JpGU, attendance at AOGS has recovered strongly since the Covid era and the 3,900 attendance was a new high for the annual meeting held in its base country of Singapore. There was a vibrant feel to the meeting with many students attending. At our JpGU booth, we were pleased to greet many old friends and many new faces.
Academic meetings, such as our upcoming JpGU-AGU 2026, have multiple roles. These include offering platforms to promote research, providing international networking opportunities that are so important to kickstart a career, and celebrating the achievements and contributions of members of the Earth and planetary science community. These gatherings also offer an invaluable platform for the leaderships of geoscience societies around the world to share information on the latest trends in our science and assess future directions.
These discussions reveal an increasing concern about the challenges posed by a combination of budget pressures and the rise of political parties with isolationist policies as we look for ways to tackle global issues such as climate change. Of particular concern are proposed U.S. federal budget plans for fiscal year 2026 that allocate zero dollars to climate research and major cuts to the workforce of the National Oceanic and Atmospheric Administration (NOAA). Work with cooperative institutes that support long-term records such as Mauna Loa Observatory are also under threat. Eliminating these programs risks erasing some of the most vital data ever collected on atmospheric change.
Global challenges require global responses, and it is important to stand in solidarity with our colleagues from around the world and speak up against shortsighted defunding of science. The JpGU motto, ‘For a borderless world of geoscience’— is now more than ever an important guiding principle for global collaboration needed to tackle the major global challenges we all face.
