The General Assembly 2021 of the European Geosciences Union (EGU) will be held entirely online from 19-30 April 2021.

The conference will be called vEGU21: Gather Online (#vEGU21).


The EGU General Assembly is a prominent annual event that brings together geoscientists from all over the world into 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.

EGU21: Gather Online, which will be accessible from around the globe, will feature the 2020 and 2021 awards ceremonies and lectures, mentoring, networking events, and many more non-technical activities in addition to nearly 700 scientific sessions.

With the return of so many in-person General Assembly traditions, the 2021 meeting will offer members an entirely different experience from last year's meeting, Sharing Geoscience Online.


The EGU is Europe’s premier geosciences union, dedicated to the pursuit of excellence in the Earth, planetary, and space sciences for the benefit of humanity, worldwide. It was established in September 2002 as a merger of the European Geophysical Society (EGS) and the European Union of Geosciences (EUG), and has headquarters in Munich, Germany.

The full program will be available in March 2021.

Abstract submission

Abstract submission closes 13 January 2021 at 13:00 CET.

The Abstract Processing Charge (APC) will remain the same as in previous years.

Access all information on submitting abstracts:


Since EGU will be offering a more complete experience in 2021, a registration fee will be charged, but the cost will be substantially lower than for an in-person annual meeting.

The final details regarding the registration fees will be released by 20 November.

Travel grants

The Roland Schlich travel support scheme will be replaced by a registration fee waiver for participants from lower- and lower-middle income countries.

PAGES working group proposed sessions

i. 2k Network: Studying the climate of the last two millennia
Conveners: Sarah Eggleston, Stella Alexandroff, Hugo Beltrami, Steven Phipps, Andrea Seim

This session aims to place recently observed climate change in a long-term perspective by highlighting the importance of paleoclimate research spanning the past 2000 years. We invite presentations that provide insights into past climate variability, over decadal to millennial timescales, from different paleoclimate archives (ice cores, marine sediments, terrestrial records, historical archives and more). In particular, we are focussing on quantitative temperature and hydroclimate reconstructions, and reconstructions of large-scale modes of climate variability from local to global scales.

This session also encourages presentations on the attribution of past climate variability to external drivers or internal climate processes, data syntheses, model-data comparison exercises, proxy system modelling, and novel approaches to producing multi-proxy climate field reconstructions.

ii. VICS: Understanding volcano-climate impacts and the stratospheric aerosol layer
Main Conveners: Graham Mann (lead), Matthew Toohey (co-lead). Co-conveners: Myriam Khodri, Claudia Timmreck, Davide Zanchettin

Volcanic aerosol clouds from major tropical eruptions cause periods of strong surface cooling in the historical climate record and are dominant influences within decadal surface temperature trends. Even the transition from the unusual 1998-2002 period of a “fully decayed to quiescence” stratospheric aerosol layer, into a more typical period of modest volcanic activity temporarily offset a substantial proportion of the subsequent decadal forcing from increased greenhouse gases.

Advancing our understanding of the influence of volcanoes on climate relies upon better knowledge of (i) the radiative forcings of past eruptions and the microphysical, chemical and dynamical processes which affect the evolution of stratospheric aerosol properties and (ii) the response mechanisms governing post-eruption climate variability and their dependency on the climate state at the time of the eruption. This can only be achieved by combining information from satellite and in-situ observations of recent eruptions, stratospheric aerosol and climate modelling activities, and reconstructions of past volcanic histories and post- eruption climate state from proxies. In recent years the smoke from intense wildfires in North America and Australia has also been an important component of the stratospheric aerosol layer, the presence of organic aerosol and meteoric particles in background conditions now also firmly established.

This session seeks presentations from research aimed at better understanding the stratospheric aerosol layer, its volcanic perturbations and the associated impacts on climate through the post-industrial period (1750-present) and also those further back in the historical record. We also welcome contributions to understand the societal impacts of volcanic eruptions and the human responses to them. Contributions addressing volcanic influences on atmospheric composition, such as changes in stratospheric water vapour, ozone and other trace gases are also encouraged. The session aims to bring together research contributing to several current international co- ordinated activities: SPARC-SSiRC, CMIP6-VolMIP, CMIP6-PMIP, and PAGES-VICS.
