AGU Editor Picks for 2017 Fall Meeting, Part II

AGU’s journal editors give their recommendations for some of the most interesting paper, panel, and poster sessions coming up at this year’s meeting.


This year’s AGU Fall Meeting has a packed schedule with more than 20,000 oral and poster presentations, as well as many other events each day. It’s thrilling to be surrounded by so much cutting-edge science, but it can be difficult to navigate such a large program of events. We asked the editors of AGU’s journals for their top picks, particularly those which should be accessible to non-specialists. The AGU Publications staff also added a few of their highlights.

As many of the events comprise multiple sessions across different days, the recommendations are grouped by broad topic. This second post covers Climate, Paleoclimatology, Hydrology, Earth Surface and Biogeosciences, and Geohealth. The first post covers Interdisciplinary, Science Communication and Publishing, Space, Planets, Solid Earth, Atmosphere, and Oceans.

Each recommendation includes the session code (with a link to the details in the scientific program), the day, time and room. All rooms are located within the New Orleans Ernest N. Morial Convention Center. For more information see the full Fall Meeting schedule.


  • Climate Dynamics: Theory, Modeling, and Breakthroughs – This Union session uses the lens of Jule Charney’s career to look at how progress can be made on big scientific questions. (Meghan Cronin, Geophysical Research Letters) – Union Session (U13A), Monday, 13:40-15:40, Room E2
  • The Resilience and Vulnerability of Arctic and Boreal Ecosystems to Climate Change – I’m particularly interested in cross-cutting sessions where the talks and posters synthesize current thinking on how the Arctic may be responding to warming. (Rose Cory, Geophysical Research Letters) – Session I (B11J), Monday, 08:00-10:00, Session II (B12C), Monday, 10:20-12:20, Session III (B13J), Monday, 13:40-15:40, and Session IV (B14A), Monday, 16:00-18:00, all in Room 356-357; Posters (B21F), Tuesday, 08:00-12:20, Poster Hall D-F
  • Tropical Cyclones: Observations, Modeling, and Predictability – (Minghua Zhang, JGR: Atmospheres) – Session I (A11S), Monday, 08:00-10:00, Session II (A12H), Monday, 10:20-12:20, and Session III (A13N), Monday, 13:40-15:40, all in Room E3; Posters (A13H), Monday, 13:40-18:00, Poster Hall D-F
  • Earth’s Energy Imbalance and Energy Flows Through the Climate System – Given the scale and impact of climate change projections it’s easy to forget that the perturbation to the earth’s energy budget is really quite small. This session focuses on how to measure those imbalances precisely enough to detect the climate change signal, and how to observe the fate of that imbalance as it melts glaciers, warms and expands the ocean, warms the polls, and so on. (Robert Pincus, Journal of Advances in Modeling Earth Systems) – Session (GC24C), Tuesday, 16:00-18:00, Room 280-282; Posters (GC21D), Tuesday, 08:00-12:20, Poster Hall D-F
  • Climate Intervention: Is Geoengineering in Earth’s Future? – The goal of the ratified Paris Accord to limit global warming to 2°C is unlikely achieved by voluntary emission reductions. Beyond greenhouse gas actions, climate intervention, or geoengineering, is a means of limiting and even reducing the extent of global warming and ocean acidification. This approach builds on humanity’s tradition of devising practical solutions to human needs and challenges, but is controversial as it presents a host of complex scientific, technical, economic, policy and ethical challenges. (Ben van der Pluijm, Earth’s Future) – Posters (GC43H), Thursday, 13:40-18:00, Poster Hall D-F; Session (GC53H), Friday, 13:40-15:40, Room 260-262


  • Geoscience Approaches to Studying the Lineage of Human Evolution – Paleoclimate, paleoecology, biomarkers, hominins, stone tools, migration, and refugia: this session has it all. Start off your AGU experience with a truly interdisciplinary session that examines hominid evolution using geoscience tools and that includes a talk by Thur Cerling, recent laureate of the GSA President’s Medal. (Valerie Trouet, Geophysical Research Letters) Understanding the influence of environmental change on human evolution is an age-old scientific problem. There have been a number of recent large projects on this topic, and the session will feature a diverse set of talks from overviews of African paleoclimate to geochemical analyses of hominid diets. (Jim Russell, Paleoceanography) – Session (PP11F), Monday 08:00-10:00, Room 343; Posters (PP13B), Monday 13:40-18:00, Poster Hall D-F

  • Natural Wetlands, Inland Waters, and the Global Methane Cycle: Time to Reconcile Top-Down Atmospheric Estimates and Bottom-Up Biogeochemical Estimates of Methane Emissions – This session seeks to resolve a long standing mystery in the global methane budget. Why are wetland emissions estimates based on process level understanding generally much smaller than those inferred from atmospheric methane data?
