In this session, led by the Mountain Research Initiative, contributions are invited that explore diverse experiences with transdisciplinary research, education, and practice, as specifically applied in the mountain context. Taking mountains as complex social-ecological systems, they offer a concrete 'microcosm' context in which to explore how global change phenomena such as elevation dependent warming and climate change, land-use change, tourism, natural hazards, energy, and social demographic change manifest and interlink simultaneously in these unique spaces. Addressing societal concerns and solutions with regards to associated impacts and implications for sustainable mountain development in response to these processes of change requires an inter- and transdisciplinary approach to research and practice. This session seeks to convey and explore the mountain-specific challenges for this mode of research, education, and training for transdisciplinary research in mountains, as well as innovations to deal with these challenges. The MRI also hopes to foster an alliance and community of practice within its organization that offers a mountains perspective to transdisciplinary research and contributes to its theory, methodology, and practice.Submit an abstract.
CL4.30/AS4.47/CR1.13/HS11.22 | MOUNTAIN CLIMATES: PROCESSES, CHANGE AND RELATED IMPACTS
Convener: Sven Kotlarski, MeteoSwiss | Co-conveners: Carolina Adler, MRI - Andreas Gobiet, ZAMG - Elisa Palazzi, ISAC-CNR - Wolfgang Schöner, KFU Graz.
Mountain climate shows high spatial variability due to complexities in terrain, steep vertical gradients in climate elements, and inhomogeneities induced by transitions to the cryosphere and between vegetation zones. The resulting patterns of climate and climate change are often highly complex and very demanding in terms of monitoring, modeling, and analysis.
This session is devoted to a better understanding of climate processes and their modification induced by global environmental change in mountain and high elevation areas around the globe (including polar regions). By invitation of the Mountain Research Initiative, contributions that investigate climate processes and climate change in mountain areas, based on monitoring and/or modeling activities, are welcomed. Particularly welcome are contributions that merge various sources of information and reach across disciplinary borders (atmospheric, hydrological, cryospheric, and ecological sciences) to cover new ground in the understanding of mountain climate and mountain climate change. Further, presentations that focus on the impacts of climate change on water management, tourism, and further social and ecological implications in mountain and downstream areas are welcome.
A planned outcome objective for this session is a synthesis contribution based on the presentations at the session as input for the IPCC Sixth Assessment Report, more specifically its cross-chapter paper on 'Mountains', which is flagged for the Working Group II report.Submit an abstract.
CR3.05 | RISKS FROM A CHANGING CRYOSPHERE
Convener: Christian Huggel, University of Zurich, MRI Principle Investigator and SLC Member | Co-conveners: Michael Krautblatter, Technical University of Munich - Josefine Lenz, Alfred Wegener Institute.
All components of the cryosphere are strongly impacted by climate change and have been undergoing significant changes over the past decades. Most visibly, glaciers are shrinking and thinning. Snow cover and duration is reduced, and permafrost, in both Arctic and alpine environments, is thawing. Changes in sea ice cover and characteristics have attracted widespread attention, and changes in ice sheets are monitored with care and concern.
Risks associated with one or several of these cryosphere components have been present throughout history. However, as well-documented atmospheric warming continues, we expect changes in the magnitude and frequency of hazards with profound implications for risks. New or growing glacier lakes pose a threat to downstream communities through the potential for sudden drainage. Thawing permafrost can destabilize mountain flanks, and eventually result in destructive rock and ice avalanches. An accelerated rate of permafrost degradation in low-land areas poses a risk to existing and planned infrastructure and raises concerns about large-scale emission of greenhouse gases currently trapped in Arctic permafrost. Decreased summertime sea ice extent may produce both risks and opportunities in terms of large-scale climate feedbacks and alterations, coastal vulnerability, and new access to transport routes and natural resources. Eventually, rapid acceleration of outlet glacier ice discharge and collapse of ice sheets is of major concern for sea level change.
This session invites contributions across all cryosphere components that addresses risks associated with observed or projected physical processes. Contributions considering more than one cryosphere component (e.g., glaciers and permafrost) are particularly encouraged. Contributions can consider hazards and risks related to changes in the past, present, or future. Discussion of both new risks and opportunities are encouraged, as long as an evidence-based, critical analysis is provided.Submit an abstract.
A wide variety of other exciting mountain and cryosphere-related sessions will be taking place during EGU 2019. The full list of sessions can be browsed and searched via the session programme on the EGU website. ABSTRACT SUBMISSION
Only 2019 EGU
members will be able to submit abstracts as a first author to the 2019 meeting and, with a few exceptions, only one abstract as a first author will be permitted.
is committed to providing the best platform for networking and communicating research, and continues its efforts towards ensuring that all participants at its annual General Assembly are able to present their work in a comfortable manner in the years to come. One of the measures adopted to ensure all presentations (orals, posters, and PICO
s) find a place is the introduction of the one-abstract rule.
As a first author, the submission of either one regular abstract plus one abstract solicited by a convener, or two solicited abstracts, is permitted. A second regular abstract can be submitted to the Educational and Outreach Sessions (EOS
) programme group (maximum number of abstracts, including solicited abstracts, remains two). More information on this can be found on the EGU website.
Another change for the 2019 General Assembly is that only 2019 EGU
members will be able to submit an abstract as first authors (co-authors are not required to have membership). To become a member, go to www.egu.eu/membership/
, where you can also renew your EGU
membership. Students receive a 50 percent discount on EGU
membership rates, and all EGU
members benefit from substantially reduced meeting registration rates, among other benefits
. From 1 December 2018, only 2019 EGU
memberships will be sold. Until 30 November 2018, those registering for membership can choose between becoming a 2018 EGU
member or a 2019 EGU
member. To submit an abstract to the EGU
2019 General Assembly, 2019 EGU
membership is required for first authors, while 2018 membership is required to participate in the 2018 EGU
is committed to promoting the participation of both early-career scientists and established researchers from low and middle-income countries who wish to present their work at the EGU
General Assembly. To encourage the participation of scientists from both these groups, a limited amount of the overall budget of the EGU
General Assembly is reserved to provide financial support to those who wish to attend the meeting. Scientists who wish to apply for Roland Schlich travel support
must be the contact author, as well as the first and presenting author of their contribution. In addition, they must submit an abstract by 1 December 2018.
Scientists at all career stages – including undergraduate and graduate students – are encouraged to submit abstracts to present their research at the conference.
To submit an abstract, browse the EGU
2019 sessions online
. Clicking on ‘please select’ will allow you to search for sessions by Programme Group (e.g. NH: Natural Hazards) and submit your abstract to the relevant session either as plain text, LaTeX, or a MS Word document. Further guidelines on how to submit an abstract
are available on the EGU
An abstract processing charge of €40 is levied on all abstracts submitted by the 10 January 13:00 CET
deadline. Late abstracts (submitted by conveners until 18 January 2019) require final approval by the Programme Committee and will be charged at €80.The deadline for abstract submission is 10 January 2019, or, for those applying for Roland Schlich travel support, 1 December 2018.
Early registration for the conference is open until 28 February 2019. Scientists can register online
on the General Assembly website from November 2018.
