What’s happening to atmospheric methane and how can we mitigate the rise?

The atmospheric methane burden has grown rapidly since 2007, with remarkable increases in the 2020s . The parallel sharp isotopic decline in the proportion of 13CH4 suggests growth is primarily driven by biological sources, including climate-warming feedbacks from natural wetlands and also human-driven agricultural sources. New radiocarbon monoxide results imply increasing atmospheric oxidizing capacity and thus higher methane emissions. There may be evidence a major climate transition is already in progress. The Union session will outline the scientific evidence for recent changes in the methane budget, and summarise progress in quantification and mitigation methods.

Responsible AI for natural hazards assessment and management

Artificial Intelligence (AI) is transforming the way natural hazards are assessed and managed, providing innovative tools for early warning systems, risk assessments, and response strategies. AI-based solutions accelerate and semi-automate the processing and interpretation of (big) data for the benefit of society and the environment. However, these advancements bring ethical challenges, including the need to ensure transparency, equity, and sensitivity to local contexts and vulnerable populations. In this session a panel will discuss the challenges and opportunities of responsible AI for natural hazards assessment and management.

EGU25 Award & Medal Celebration

In 2025 the European Geosciences Union (EGU) selected 49 recipients of our prestigious Union Medals and Awards, Division Medals, and Division Outstanding Early Career Scientist Awards. These individuals are honoured for their important contributions to the Earth, planetary and space sciences and during the week of EGU25 many of them have been giving an invited Medal or Award lecture sharing their work. The winners of this year’s Medals and Awards are also being celebrated this evening at a special Award Celebration.

How to translate fundamental research into societal and policy impact

Research funding enables Europe to drive innovation, address societal challenges, and maintain global competitiveness. While the value and benefit of applied research is relatively easy to understand for policymakers and the public, the link between fundamental research and societal value is less evident for them. As a consequence, it is increasingly clear that Europe lags behind other major powers in terms of investment in transformative frontier research and that this threatens its future. Involvement of researchers in policymaking and other societal actions appears to be limited, often not well recognised, and not easily accessible. In addition, the interest in specific projects usually fades away after their termination whereas the repercussion of obtained results may only arrive later. This Great Debate will explore the procedures to bring research results closer to policy, economy and society, and will debate: How can individual researchers contribute effectively in societal and policy actions? Which mechanisms should be created to facilitate the harnessing of research results? Should the use of research results be left in the hands of dedicated professionals, and where is research budget best invested?

Meet our Artists in Residence – Annabelle Foster

Annabelle Foster (@Volcannabelle) is an illustrator, science communicator and volcanology researcher, with a particular focus on silicic lava formation. At the General Assembly she will be creating a large-scale, fantasy-style world map that represents the experiences and research presented at the General Assembly. The map will be constructed live during the week of the meeting and will also be available online in an interactive format!

Head over to her booth in Foyer D and talk to her about your research and her artwork!

Bridging natural and social sciences to study societal responses to extreme weather events

Extreme weather events such as tropical cyclones, heatwaves and floods threaten populations around the world. There is growing literature at the intersection of the natural and social sciences studying the impacts of extreme weather events on populations as well as peoples’ behavioral, attitudinal, and emotional responses. These studies have been conducted in interdisciplinary settings, where social scientists closely collaborate with natural scientists to study populations that have been, or will be, impacted by extreme weather events, yet only few studies are currently harnessing the full potential of interdisciplinary collaborations. This session aims to provide a platform for this interdisciplinary work on extreme weather events.

Geodesy – From Invisible to Essential

Geodesy is a fundamental Earth sciences discipline that describes the Earth’s place in space (i.e., shape, size, orientation, gravity field) over time. Although often invisible, geodesy is widely used in various sectors where precise positioning, navigation, and timing are required, and is essential for socio-economic development. In the coming decade, the use of geospatial information is expected to grow substantially (e.g., for hazard risk assessment, natural resource monitoring, pandemic prevention), leading to increased demand for geodetic services. But where do we stand today? Are we fully aware of the critical role of geodesy for societal needs? And what challenges are we facing? This session will present the First Joint Development Plan for Global Geodesy, along with the concept of a global geodesy supply chain.

Open Session in Geomagnetism

This session platforms contributions that fall within the broad spectrum of Geomagnetism, but are not directly appropriate to any of the other proposed sessions. The session will feature contributions on theory and simulations, instrumentation, laboratory experiments and field measurements, data analysis and interpretation, as well as inversion and modelling techniques.

Collaborations, Tools and Services Towards an Integrated Research Data Infrastructure

Addressing global environmental and socio-technical challenges requires interdisciplinary, data-driven approaches. Today’s research produces unprecedented volumes and complexity of value-added research data and an increasing number of interactive data services, putting traditional information management systems to the test. Collaborative infrastructures are challenged by their dual role of advancing research and scientific assessments while facilitating transparent data and software sharing. This session will highlight innovative platforms, frameworks, datacube tools, services, systems, and initiatives designed to enhance access and usability of data for research on a range of topics, providing a realistic overview on the tools, service landscape and ongoing collaborations that enable researchers to address pressing problems.

Advancing the integration of citizen and stakeholders’ knowledge in disaster risk assessment, reduction and governance

The global interconnection of social systems often causes hazard impacts to exceed regional boundaries or socioeconomic sectors, propagating and amplifying their losses. In turn, successful disaster risk reduction and climate adaptation strategies engage citizens and stakeholders to attune to their conditions, capacities, and context. Urban areas are especially vulnerable to hazards, as they act as nodes in global networks, locate in exposed settings (e.g., in coastal areas or mountain slopes), and concentrate physical and social assets. This session will provide a forum for research that integrates citizens' and stakeholders’ knowledge in risk analysis and governance, by collecting recent scientific advances in the multifaceted societal contributions to climate vulnerability, exposure, and risk assessment and reduction.
