AGU Fall Meeting 2020

07.12 - 11.12.2020  
San Francisco, USA

The 2020 AGU Fall Meeting will be held mainly online, and potentially also in San Francisco, California, USA, from 7-11 December 2020.

The theme is "Shaping the Future of Science".

*Update from the organizers*

AGU Fall Meeting will be mostly virtual and remain the global convening meeting for the Earth and space sciences community.

If science and health professionals tell us it is safe for groups to convene, AGU will host a regional gathering in San Francisco. Depending on where you're located (and if it's safe), you can create your own mini-#AGU20 watch party or hub. We'll offer guidance if that's of interest.

With more than 1,000 sessions as well as hours of networking and poster hall time, all of them will be scheduled to work for multiple time zones around the world. Content will also be live and on-demand so you can watch (or binge) at your convenience.

With all of this content, Fall Meeting will be concentrated 7-11 December. But we'll extend the time frame to earlier in December for programming around specific neighborhoods.

There will be a registration fee that is about 50% less than the in-person rate and lower rates for graduate student and other groups. We assure you that the value that you have always experienced at Fall Meeting in-person will remain in our virtual version.


Moscone Convention Center, San Francisco


Fall Meeting is the largest gathering of Earth and space scientists in the world. Back in San Francisco after celebrating the Centennial, Fall Meeting 2020 aims to bring a diverse and relevant set of topics to help move Earth and space science forward.

Session proposals

Due to COVID-19, AGU has extended the deadline to submit a Fall Meeting session, town hall, workshop and innovative session proposal until Thursday 23 April 2020.

Access the guidelines and submit a proposal:


Abstract submission opens 22 June and closes 29 July 23:59 (ET). Submit abstracts here:


Registration (and housing) opens in August.

PAGES working group sessions

i. C-PEAT: Peatlands dynamics, disturbance, and restoration (Session ID: 102676)
Convener: Estelle Chaussard. Co-conveners: Hinsby Cadillo-Quiroz, Julie Loisel and Alison Hoyt

Peatland degradation resulting from land-use change, drainage and burning is a major environmental problem. Environmental consequences include loss of biodiversity, increased CO2 emissions, fires and haze, land subsidence, and flooding. Improved quantitative theory is needed to relate the factors controlling peat degradation rates across the landscape to these environmental impacts.

This session aims to gather studies focusing on 1) the response of peatlands to anthropogenic and environmental disturbances (i.e. drainage or restoration), 2) quantitative understanding of peatland dynamics and biogeochemical cycles (i.e. fluxes of water, dissolved organic carbon, CO2 and/or methane), and 3) constraints on the role of peatlands in contributing to and responding to climate change. We welcome studies employing a range of methods, including but not limited to field measurements, laboratory experiments, remote sensing, and process-based or large-scale models. Of particular interest are spatially and/or temporally explicit datasets, and studies which integrate remote sensing and ground-based datasets.

ii. C-PEAT: Wetlands and global change: impacts on wetland function and ecosystem services from the paleo-record through the Anthropocene (Session ID: 104025)
Convener: Sarah A Finkelstein. Co-conveners: Miriam Jones, Debra A Willard and Sheel Bansal

Wetlands are a globally important resource, playing a key role in global biogeochemical cycling, hydrologic buffering to storms and floods, providing wildlife habitat, and serving as archives of past wetland history. This session focuses on wetland functional responses to environmental changes. Functional responses could include (but are not limited to) controls on rates of carbon accumulation or methane release; impacts of hydrological change or flooding on vertical accretion of wetland sediments; changes to biotic communities. We invite abstracts investigating any aspect of wetland functional response to environmental change over all time scales, including paleo-records, analyses of recent responses to human impacts, and forward modelling of future wetland dynamics in the Anthropocene. By integrating papers focusing on wetland functional responses in the past, present and future, this session aims to stimulate insights on the role of wetlands in the Earth system and provide evidence to guide wetland conservation and restoration.

iii. PALSEA and QUIGS: In and out of the ice age: Sea level, ice sheets, and climate during ice age transitions (Session ID: 103946)
Convener: Jacqueline Austermann. Co-conveners: Tamara Pico, Benjamin Keisling and Jerry McManus

Earth’s climate system has oscillated between warm interglacials and cold glacial maxima across the Pleistocene – what was once thought to be a simple and repeating saw tooth pattern is now recognized to be more complex. For example, glaciations might not be slow and glacials and deglaciations might vary significantly from one cycle to the next. Understanding these variations is important to identifying drivers of ice age change, and necessary to appropriately use past warm periods to inform Earth’s response to future warming.  
In this session, co-organized by the PALSEA and QUIGS working groups, we invite contributions that present observation- and/or modeling-based studies of glacial-interglacial changes associated with sea level, ice sheets, and climate. Time periods of interest include (but are not limited to) the last and penultimate deglaciation, the last interglacial and the Holocene, the last glacial inception, and the transition into the last glacial maximum.
