AGU Fall Meeting 2019

09.12 - 13.12.2019  
San Francisco, USA

The 2019 AGU Fall Meeting will be held in San Francisco, California, USA, from 9-13 December 2019.


The AGU 2019 Fall Meeting will mark another dynamic year of discovery in Earth and space science, and provide a special opportunity to share science with world leaders. As the largest Earth and space science gathering in the world, the Fall Meeting places you in the center of a global community of scientists drawn from myriad fields of study whose work protects the health and welfare of people worldwide, spurs innovation, and informs decisions that are critical to the sustainability of the Earth.

Call for abstracts

The abstract submission site is now open:

The deadline for all submissions is Wednesday 31 July at 23:59 EDT. Abstracts will not be accepted for review after this date.


Registration and housing will open in mid-August:

Planned PAGES sessions

i. 2k Network: PP008: Climate of the Common Era (Session ID: 78289)
Conveners: Kevin J Anchukaitis, Kim M Cobb, Edward R Cook, and Jason E Smerdon

This session marks the 10th anniversary of the Climate of the Common Era session and highlights the last decade of research on all aspects of the climate of the last 2000 years. Contributions that synthesize the last decade of advances in our understanding of past climate during the Common Era are particularly welcome and encouraged. This session will focus on the progress that has been made in improving our understanding of the climate system through the development and analysis of new proxies and reconstructions, progress and challenges in data syntheses, advances in methodologies and proxy system modeling, and the newest generation of paleoclimate model simulations.

ii. C-PEAT: B123 - Understanding past, present, and future peatland responses to natural and anthropogenic drivers of change (Session ID: 79617)
Convener: Julie Loisel, Texas A&M University College Station; Co-Conveners: Sarah A Finkelstein, University of Toronto; Zicheng Yu, Lehigh University

Peatlands have played a key role in the global carbon cycle during the Holocene and previous interglacials/interstadials, as net long-term atmospheric sinks for carbon dioxide and substantial sources of methane. Recently, an increasing amount of observational, experimental, and modeling work has been put towards assessing the sensitivity of peatlands to changing climates and the fate of their large carbon stocks under warmer temperature regimes. There has been an effort to expand current knowledge to the tropics, sub-tropics, and temperate zones, where peatlands are abundant, and where humans are major drivers of change.

For this PAGES' C-PEAT working group session, we invite the broad peatland community to present their work on past, present, and future peatland responses to natural and anthropogenic disturbance, including but not limited to: lab and field experiments, synthesis work, flux measurements, peat-based paleoclimatic records or new peat-based proxy development, and process-based or large-scale simulations.

iii. PALSEA: PP006 - Centennial Session: 100 Years of Ice Sheet and Sea-level Science (Session ID: 79110)
Conveners: Jacqueline Austermann, Lamont-Doherty Earth Observatory, Columbia University, Harvard University; Benjamin Peter Horton, Rutgers University New Brunswick; Tamara Pico, Harvard University; Alessio Rovere, Lamont Doherty Earth Observatory

Sea level and ice sheet science predates the foundation of the AGU. More than 2000 years ago, the Greek philosopher Strabo linked volcanic activity in the Mediterranean to land-level changes and periodic marine inundations. This community strives to determine the rates, mechanisms, and geographic variability of former sea levels, the sensitivity of ice sheets to climate change, the response of the solid Earth and gravity field to ice mass redistribution, and to constrain statistical and physical models used to project future sea-level rise, which hinges on an improved understanding of ice-sheet behavior in the geologic past.

We celebrate AGU’s centennial by highlighting the past 100 years of scientific achievement and to set our vision towards the next 100 years. As part of PALSEA (PALeo constraints on SEA level rise), a PAGES-INQUA working group, we seek abstracts that illustrate observations, analyses, and modeling of changes in sea level and ice volume.

iv. OC3: PP010 - Deep Ocean Circulation Changes and Their Impacts (Session ID: 83829)
Primary Convener: Andreas Schmittner, Oregon State University; Conveners: Ayako Abe-Ouchi, University of Tokyo; Lorraine E Lisiecki, University of California, Santa Barbara; Aixue Hu; NCAR

Fluctuations in the Atlantic Meridional Overturning Circulation (AMOC) have been implicated in past climate, ecosystem, and carbon cycle changes. The Southern Ocean and North Pacific may also have played important roles in past climate and carbon cycle variability. Yet quantitative reconstructions of deep ocean circulation remain challenging for both modern and past climates.

With recent community efforts focussing on estimating the modern and late Holocene AMOCs (UK RAPID/US AMOC) and reconstructing ocean circulation and carbon cycling (OC3) during the last deglaciation, here we invite modern oceanographers, paleoceanographers and modelers to assess the current understanding of deep ocean circulation changes and their impacts.

Planned side meetings

The OC3 working group will hold its final meeting after the AGU, on 14 December. All details here.

Future Earth-related session

GC080 - The Changing Face of Wildfires and Effects on Human Health (Session ID: 79397)
Primary Convener: Hannah Liddy, Columbia University of New York; Conveners: Benjamin Poulter, NASA Goddard Space Flight Center; Robert D Field, Columbia University of New York; Robert B Jackson, Stanford University

Wildfire behavior is changing as climate extremes combine with decades of fire suppression and forest management activities to alter fuel loads. In addition, urban development and rapid sub-urban sprawl have complicated the wildland-urban interface, bringing people and fire together in ways that risk property, infrastructure, and health. In this session, we bring together experts in fire behavior, fire modeling, atmospheric chemistry, and human health to explore how wildfires in natural and managed systems are changing in response to climate extremes. In particular, this session invites abstracts on 1) fire regime variability and climate-related drivers, 2) fire behavior and the suitability of existing fire spread models to represent changing conditions, 3) trace-gas emissions and their atmospheric chemistry and transport, and 4) public health impacts via direct and indirect fire and emission processes.

WCRP sessions

PAGES' scientific partner World Climate Research programme (WCRP) will celebrate its 40th Anniversary with the "WCRP Climate Science Week":
