About
The EGU General Assembly 2025 brings together geoscientists from all over the world to one meeting covering all disciplines of the Earth, planetary, and space sciences. The EGU aims to provide a forum where scientists, especially early career researchers, can present their work and discuss their ideas with experts in all fields of geoscience.

MRI-Endorsed Sessions at the EGU
AS1.38 Mountain Weather and Climate
Co-organized by CL3.1/CR7
Convener: Sven Kotlarski | Co-conveners: Anna Napoli, Stefano Serafin, Maria Vittoria Guarino, Carolina Adler
Mountains cover approximately one-quarter of the total land surface on the planet, and a significant fraction of the world’s population lives within, in their vicinity, and downstream. Orography critically affects weather and climate processes at all scales and, in connection with factors such as land-cover heterogeneity, is responsible for high spatial variability in mountain weather and climate. This session is devoted to showcasing research that contributes to improving our understanding of weather and climate processes in mountain and high-elevation areas around the globe, as well as their modification induced by global environmental change. This includes the interaction of mountain weather and climate with the terrestrial cryosphere.
We welcome contributions describing the influence of mountains on the atmosphere on meteorological and climate time scales, including terrain-induced airflow, orographic gravity waves, orographic precipitation, land-atmosphere exchange over mountains, forecasting, and predictability of mountain weather. Contributions connected with the TEAMx research programme are encouraged.
We also encourage theoretical, modeling and observational studies on orographic gravity waves and their effects on the weather and the climate.
Furthermore, we invite studies that investigate climate processes and climate change in mountain areas based on monitoring and modeling activities. Particularly welcomed are contributions that connect with and address the interdisciplinary objectives of the Elevation-Dependent Climate Change (EDCC) working group of the Mountain Research Initiative.
CR1.7 Changing Cryosphere under a Changing Climate – from Observations to Environmental and Social Effects
Co-organized by HS13, co-sponsored by WMO
Convener: Wolfgang Schöner | Co-conveners: Marcelo Somos-Venezuela, Carolina Adler, Lijuan Ma, Elias J. Deeb
Climate change has a significant impact on the amount, spatial and temporal distribution of the cryosphere (snow, glaciers, permafrost), and associated water resources in different regions of the world. Several studies show that the response of the cryosphere to climate change is not only an effect of temperature change, but depends on several factors such as geographical location (climate zone), latitude and regional atmospheric forcing (e.g. interaction with synoptic-scale atmospheric currents), among others. However, observational capacity and process understanding of these interactions vary considerably within and between regions. For example, despite the importance of snow in mountainous regions, a comprehensive global inventory of mountain snow based on robust data is still lacking. Filling this research gap is one of the main motivations for the Joint Body “Status of Snow Cover in Mountain Regions”, a joint effort of IACS, WMO and the MRI.
The aim of the session is to bring together the knowledge and experience of researchers from and working in different regions of the world (e.g. mountains, and polar regions, such as theArctic) working on similar topics related to climate-induced changes in the cryosphere. An expected outcome of the session is therefore to take stock and present the current state of knowledge and to identify research gaps that may be useful for future work. Given the overall importance of the cryosphere for ecology, economy and human life in general, researchers from different and also interdisciplinary fields are invited to contribute, for all regions of the world and using a variety of data sources and analytical methods (including modelling experiments, in situ observations, satellite products or reanalysis data).
ITS3.8/NH13.16 Climate Impacts and Environmental Change in Mountain Social-Ecological Systems
Convener: Margreth KeilerECS | Co-conveners: Carolina Adler, Sven Fuchs
Mountains are complex social-ecological systems and natural laboratories in which to tangibly explore and understand how drivers and processes of global change manifest in specific places. In this session, we invite inter- and transdisciplinary contributions that examine past, present, and future environmental change, their associated impacts for ecosystems and people in mountain environments, and measures taken to address these impacts. This session is open to conceptual as well as empirical measurement and/or modelling or scenarios studies of mountain climate, cryosphere, ecology, hazards, and hydrology, which also incorporate studies on intersecting socio-economic dimensions and risks. Mountains as complex terrain can be difficult to adequately parameterize in (climate) models and many areas of the world lack high-elevation monitoring infrastructure that can record data at the relevant locations, densities, scales, frequencies, and resolutions needed. Likewise, there is a need to capture and account for socio-economic changes such as demographic and land-use change and their projections to improve our understanding of how hazards, vulnerability, and exposure interact in terms of impacts and risks.
We particularly welcome contributions that describe how steps are being taken to address such knowledge gaps, including high-elevation integrated monitoring efforts, observations along elevational gradients, climate downscaling strategies and remote sensing innovations, and integration methods that include societal data and information to characterise and represent a more comprehensive systems approach to global change. As 2025 marks the UN-declared International Year for Glaciers’ Preservation, and the kick-off to the UN Decade of Action for Cryosphere Sciences, this session especially invites contributions that take a multi-disciplinary perspective and approach to addressing the challenges and opportunities posed by a changing cryosphere in mountain regions, with particular attention to the human dimensions associated with adaptation and resilience.
This session is endorsed and supported by the Mountain Research Initiative and the Institute for Interdisciplinary Mountain Research of the Austrian Academy of Sciences.
