Welcome to the EGU General Assembly! The Programme Committee is proud to present a stimulating and unique programme that covers the full range of subjects in the Earth, planetary and space sciences. This year we are also thrilled to be able to offer a General Assembly that is more hybrid than any we have managed before. Not only are all three standard presenting formats (posters, orals and PICOs) back on-site in Vienna, but also each offers a virtual component. This new set-up gives all our attendees full flexibility of choice in how they want to present their research and participate in EGU23.
This year’s programme includes 925 scientific sessions, 51 short courses, 11 union-wide Union Symposia and Great Debates, 39 Medal and Award lectures, as well as the Job Centre, Artists in Residence, Science-Policy events and much, much more. It is also a festive year as EGU turned 20 last September and, for a member-led organisation, there is no better way to celebrate our anniversary than by getting together.
We hope this week will give you the chance to really take the time to discuss your science in depth and detail, to build new connections and reinforce established ones, to cultivate new ideas and enjoy the company of other researchers. As we have seen in the last few years the EGU community is a strong, welcoming and curious one, dedicated to sharing ideas and knowledge in order to better serve humanity and the planet, and we want to thank all our attendees for joining us, whether on-site in Vienna or virtually, online.
We hope you enjoy the week and taking some time for science!

Despite a large reported interest, significant barriers prevent academics from contributing to decision-making processes, including a lack of knowledge about how to engage, insufficient time to participate, and a lack of acknowledgement of individual contributions beyond citations. For example, engaging with policy decision-making processes is not necessarily rewarded in the same way as other activities, such as publishing in journals or generating press coverage. This acts as a significant barrier to participation for many academics, but particularly early career researchers. This Union Symposium will explore various solutions to these barriers, including the role of funding agencies and academic institutions and the policy institutions themselves. Whatever the solutions are, they require the foundation of new incentive structures, better recognition of engagement, and cultural change that will require establishing a dialogue between academics, funding bodies, and policy institutions.

Voting has opened today for the thirteenth annual EGU Photo Competition! Ten creative and curious images were selected from 100’s of entrants for this year’s contest on the imaggeo website, in the hopes of being voted one of the top three photos of the year, awarding the winner with free registration to next year’s meeting. The winners are selected by you and voting is open until 18.00 (CEST) on Thursday 27 April. Winners are announced on Friday on the EGU blog, geolog.egu.eu, and at the EGU Booth in Hall X2.
Vote for your favourite.
So far, the interannual-interdecadal variability and the long-term trend of extreme climate events have not been well understood. An important reason is that the mechanisms of extreme climate events are often complex. This session will examine the variability, mechanisms, and prediction of various extreme climate events, in relevant contexts.

Is social media a worthwhile vector for communicating science and reaching non-expert audiences? Proponents of social media highlight its ability for bringing otherwise inaccessible research to a global network, spreading research to new audiences and providing a voice to often under-represented or margianlised communities, but communicating via social media can result in a loss of nuance and accuracy required by the extremely short time-frames of the format. Critics also say that it requires a considerable investment in time and money, which can distract from core research activities. In this Great Debate, the panellists will discuss if effective communication on social media is possible or whether scientists are better investing their efforts elsewhere.
GDB5: 14:00–15:45 (CEST) Room E1
This session (UMI3) is the annual meeting held during every General Assembly to recognise and thank the outgoing volunteer Division Presidents and other Union officers and to introduce and welcome the new ones!
Join us in Room E1 (yellow level) from 12:45 (CEST) today. This session is only available to on-site attendees.
Palaeoclimate modelling is a challenging endeavour, not just due to the vast time scales that are often involved, but also the range of climate conditions that need to be incorporated. This session includes studies on model development, simulations and model-data comparisons, in an attempt to better simulate the past and facilitate future climate projections.
PS5.4: Orals: 16:15–18:00 (CEST) Room 1.34; Posters: 16:15–18:00 (CEST); on-site: Hall X4, virtual: vHall ST/PS
Plastic pollution in freshwater systems is a widely recognized global problem with potential environmental risks to water and sediment quality. Furthermore, freshwater plastic pollution is also considered the dominant source of plastic input to the oceans. Despite this, research on plastic pollution in freshwater environments and data and knowledge from field studies are still limited. This session will explore the current state of knowledge and activities on macro-, micro- and nanoplastics in freshwater systems.
HS2.3.4: Orals: 14:00–15:35 (CEST) Room B; Posters: 16:15–18:00 (CEST); on-site: Hall A, virtual: vHall HS
The increasing availability of remotely sensed observations and computational capacity, drive modelling and observational glacier studies towards increasingly large spatial scales. These large scales are of particular relevance, as they impact policy decisions and public discourse. At a global scale, glaciers are among the most important contributors to present-day sea level change. This session will focus on advances in observing and modelling mountain glaciers and ice caps, at regional to global scales.
CR1.1: PICO: 16:15–18:00 (CEST) PICO spot 3a
Glacial Isostatic Adjustment (GIA) describes the dynamic response of the solid Earth to ice sheet glaciation/deglaciation, which affects the spatial and temporal sea level changes, and induces surface deformation, gravitational field variation and stress changes in the subsurface. This session draws on observational data in order to better investigate the interactions between the ice sheets, solid Earth and sea levels.
ITS1.5/GI1.5: Orals: 10:45–12:20 (CEST) Room 0.94/95; Posters: 14:00–15:45 (CEST); on-site: Hall X4, virtual: vHall ESSI/GI/NP
Despite widespread media coverage of the dramatic increase in frequency and ferocity of extreme weather events in recent years, it often seems that policy and public opinion still lag a long way behind what is required to address the climate crisis effectively and rapidly. This Great Debate asks why this might be the case, and critically examines the role of the Earth sciences community in driving public opinion and policy making. It will examine the messaging, the tone and the science that shapes how climate change is presented to the public and policymakers, and look at how our community can help to drive climate action before it is too late.

Don’t miss out the EGU Exhibition where you will get a chance to talk with industry representatives and members of other academic, scientific and publishing organisations. Several of the Exhibitors are running special events throughout the week, check the Exhibition events portal for events from lunch time talks (such as the ones organised by ENVRI) to the daily Open Science & Data Help Desk drop in sessions, to ‘Meet the Editors’ events (such as those being held by Cell Press, Elsevier and Nature).
List of Exhibitors.
This open session includes presentations on a wide range of ocean processes and oceanographic techniques, as well as advances due to new instruments and techniques such as gliders and autonomous vehicles. The session includes studies relating to all marine disciplines as well as interaction of the ocean with the atmosphere and/or the cryosphere.
