Climate change, morals, values and policies

The climate challenge is no longer only about understanding the Earth system, it is also about understanding ourselves as humans. As a global society, response to climate change information and climate action policies is shaped not only by scientific evidence, but also by moral values, cultural identities, religious beliefs, fears, and psychological dynamics. Attitudes that may appear irrational often reflect deeper questions of meaning, trust, and social belonging. How can scientists and governments communicate climate science in ways that resonate with diverse societies without resorting to manipulative tactics? How can decision-makers design ethical and inclusive policies that inspire meaningful action at individual, community, and societal levels? This Union Symposium will bring together experts from multiple disciplines to explore these questions through both scientific research and practical experience, examining the moral, psychological, cultural, and social dimensions that shape public engagement with climate change.

Integrated Stratigraphy: Best Practices in Age-Depth Modelling & First Outcomes of the TIMES Initiative

Earth history is marked by significant disruptions in global climate, changes in geochemical cycling, and faunal turnover events. The investigation of these events across Earth history is based on accurate and integrated stratigraphy, utilizing a broad range of geological and geophysical techniques, unique stratigraphic features, and established and novel paleoclimate and paleoenvironmental proxies. This session will bring together specialists in all branches of stratigraphy, geochronology, paleoclimatology, and paleontology, spanning from the Archean to the Holocene, to introduce new techniques and methods that help improve the stratigraphic and paleoenvironmental toolbox.

Have we broken the Earth’s water cycle? Pathways from Planetary Boundaries to local Safe Operating Spaces

The planetary boundaries framework defines a safe operating space for humanity, measuring with indicators and thresholds how pressures on the environment have destabilized the Earth system with profound consequences for environmental health, economic development and social equity. The freshwater boundary, initially defined as consumption of no more than 4000 cubic kilometres of freshwater per year, has now been considered transgressed. Yet this global figure conceals essential details: how are pressures spread across regions and sectors, and how do surface and groundwater each contribute? If these combined pressures are indeed disrupting the Earth’s water cycle, what actions can we take to bring it back onto a sustainable path? This Union-wide Symposium brings together diverse perspectives on how water, land use and ecological systems, respond across levels to climate change and changing human activities, from the global dimension to national policies and local river basin management. The discussion will highlight both research advances and operational strategies that the geoscience community can mobilize to confront these challenges, empower stakeholders, and identify pathways to more sustainable management within the planet’s freshwater boundaries.

The costs of Natural Hazards: direct, indirect, tangible and intangible aspects

Natural hazards pose serious threats to human health, settlements and the environment. The nature of impacts can be monetizable or hard to measure through economic metrics. Impacts can occur immediately due to the effects of a physical forcing or might persist, evolve and aggravate or resolve in time. This session will gather researchers interested in the scientific advances related to the multiple facets of natural hazard impacts, i.e., direct, indirect, tangible and intangible losses, in both theoretical and practical aspects of impact assessment, with a view to fostering interdisciplinary dialogue and advancing the field.

From research to operations: advanced hydrometeorological forecasting and early warning at various scales and horizons

Hydrometeorlogy exists at the critical intersection between the land surface and the lower atmosphere, examining the way that water and energy moved between them. Particularly relevant in rainfall-induced hazards, flash floods and other hydro-geophorphic hazards, this session aims to advance probabilistic hydro-meteorological forecasting from research to operations (and operations to research) across spatial scales and time horizons. New studies presented will illustrate current progress in monitoring, modeling, and forecasting of rainfall-induced hazards (including their impacts) and discuss how advanced hydrometeorological ensemble approaches are to be scientifically robust while also being user-centric, impactful, and effectively communicating uncertainty to support decisions.

Paleomagnetic Variations and Geomagnetic Field Modelling: Data, Simulations, and Future Challenges

This session explores palaeomagnetic records, palaeosecular variation and geomagnetic field modeling through the integration of directional, absolute, and relative palaeointensity data from palaeomagnetic, archeomagnetic, and historical observatory records. By combining experimental data with numerical simulations and statistical approaches, we aim to advance understanding of geomagnetic field behavior across a wide range of spatial and temporal scales. The session will include presentations of new palaeomagnetic data, directional and intensity datasets, methodological developments, regional to global reconstructions, and innovative perspectives that enhance our ability to model and interpret the evolution of the Earth’s magnetic field through time and space.

Land use, land management, and land cover change (LULCC) and their effects on the Earth system

Human activities on land, also called 'Land use, land management, and land cover change', shape the climate by altering land-atmosphere fluxes of carbon, water, energy, and momentum. An increasing focus on land-based climate mitigation and adaptation strategies to meet more stringent targets has expanded the range of land management practices considered specifically for their potential to alter terrestrial carbon cycling or mediate favorable environmental conditions. This focus has also called attention to potential tradeoffs between climate-centric aspects of land use, land management, and land cover change, and its influences on biodiversity, hydrology and other environmental factors. This session will explore how advancements in modelling and measurement techniques are opening new possibilities to better describe land use, land management, and land cover change and its effects on the Earth system at multiple temporal and spatial scales.

Climate Change and Global Health Risks from Interdisciplinary Perspectives

Climate change is reshaping the conditions that sustain human health. Rising temperatures, shifting precipitation patterns, and intensifying extremes are linked to diverse risks, from heat-related illness, kidney disease, and suicide to mortality from wildfires, tropical cyclones, and infectious diseases. These impacts extend beyond health to affect labor capacity, energy demand, and economic productivity, underscoring the interconnectedness of climate and society. This session will share new studies that investigate the different pathways linking climate extremes to human health and well-being worldwide, especially highlighting those that leverage diverse data sources, including observations, health and socio-economic data, reanalyses, climate models, large ensembles, and AI-based models, to deepen our understanding and improve prediction and projection across various time scales.
