AGU Fall Meeting 2020

Online meeting
Meeting Category

The 2020 AGU Fall Meeting will be held online from 1-17 December 2020.

The Fall Meeting will be concentrated from 7-11 December, but to minimize scheduling conflicts, events will be extended around the meeting from 1-17 December.

The theme is "Shaping the Future of Science".


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.

PAGES working group sessions

i. 2k Network*: Climate of the Common Era (Session ID: 104704)

Convener: Bethany Coulthard. Co-conveners: Sloan Coats, Tripti Bhattacharya and Sylvia Dee

This session highlights recent work on all aspects of the climate of the last 2000 years (the Common Era), using new proxy records, data syntheses, reconstruction methodologies, proxy system modeling, and paleoclimate model simulations. Contributions that combine several of the above areas or that utilize the latest generation of paleoclimate model simulations are particularly welcome. This year we hope to emphasize model-data comparisons, particularly those that leverage “isotope-enabled” model simulations, to characterize uncertainties in proxies and models, and how these uncertainties impact our knowledge of past and future climate variability and change. We are excited for invited talks from Sam Stevenson (University of California, Santa Barbara) and Sam Munoz (Northeastern).

*This is a continuation of the session previously run by PAGES 2k Network members for the past decade.

ii. 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.

iii. 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.

iv. CVAS: Advancing paleoclimatology by combining models and data (Session ID: 105004)

Convener: Dan Amrhein. Co-conveners: Sylvia Dee, Allison Lawman and Michael N Evans

Synthesizing constraints from paleoclimate proxy data and numerical models offers powerful tools to test hypotheses about past climates, quantify the limits of knowledge, and design the next generation of modeling and data retrieval efforts. This session will highlight developments in relating environmental variables to proxies of past conditions (including proxy system models) and techniques for combining numerical models and data (including data assimilation).

Topics will include new calibrations and tools for representing proxies in numerical models, reconstructions of past ecosystems and climates, uncertainty quantification, and analysis of results to address key paleoenvironmental questions. These questions may include but are not limited to assessing climate sensitivity and characterizing internal climate variability, large-scale dynamics, and extremes. Contributions can span the range of proxy systems, data assimilation techniques, and time scales. Work illustrating open source platforms that lower the bar to paleoclimate data assimilation is especially encouraged.

v. PALSEA and QUIGS: In and out of the ice age: Sea level, ice sheets, and climate during ice age transitions (See below for session links)

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.

Session times:

Posters Tuesday 8 December:

1st Oral session Tuesday 8 December 20:30 EST (Wednesday 9 December 01:30 UTC):

2nd Oral session Wednesday 9 December 7:00 EST (12:00 UTC):

PALSEA and QUIGS leaders invite you to the oral sessions and to look at some of the 19 posters that present exciting new research results. The times that poster presenters will be 'at their posters' is below. Also keep an eye on the poster session website (link above) as other presenters might still add their chat times later. Just like in a real poster session, you can stop by the posters to talk about science but also to just say hello.

The oral sessions will have 30 minutes of mini presentations and 30 minutes of discussion, so bring any questions you might have on Sea Level, Ice Sheets, and Climate During Ice Age Transitions.
