The General Assembly 2021 of the European Geosciences Union (EGU) will be held from 25-30 April 2021 in Vienna, Austria.

Venue

Austria Center Vienna (ACV)

Description

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.

The annual EGU General Assembly is Europe’s largest and most prominent geosciences event. It attracts more than 16,000 scientists, more than half of which are early career, from all over the world.

The meeting’s sessions cover all disciplines in the Earth, planetary and space sciences. Each annual General Assembly typically features more than 16,000 oral, poster and PICOs (interactive presentations that combine the advantages of orals and posters).

Aside from the disciplinary sessions, which cover topics selected by each scientific division (or programme group), the meeting also features many Union-wide sessions. These include Great Debates and Union Symposia, inter- and transdisciplinary sessions, medal lectures, short courses, and Education and Outreach Sessions (such as the Geosciences Information For Teachers workshop, GIFT).

The General Assembly also features a job centre, artists-in-residence, and a newsletter, EGU Today, which highlights sessions, events, and exhibitions each day of the meeting. These and other activities, as well as the scientific sessions, are often announced on GeoLog, the EGU blog, as well as EGU’s social media channels, which are very popular during the Assembly.

Other features of the Assembly include a daily newsletter, EGU Today, which highlights sessions and events each day of the meeting and exhibitions. These and other activities, as well as the scientific sessions, are often highlighted on GeoLog, the EGU blog, and EGU social media channels, which see keen presence during the Assembly.

The EGU also hosts journalists and organises press conferences in a dedicated Press Centre at the meeting.

Background

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.

PAGES' working group proposed sessions

i. VICS: Understanding volcano-climate impacts and the stratospheric aerosol layer
Main Convenors: Graham Mann (lead), Matthew Toohey (co-lead). Other session convenors: 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.
