Conveners of the following five sessions invite presentations from the
Arctic community:
Session 7605: Extratropical and High-latitude Storms,
Teleconnections, Extreme Weather, and the Changing Polar Climate
Conveners: Xiangdong Zhang, Kent Moore, Xiaojun Yuan, and Qinghua Ding
Synoptic storms and large-scale teleconnections are prominent features
characterizing daily-to-decadal climate variability in the extratropics
and high-latitudes. Storms often bring extreme weather, including
high-wind events, large ocean waves and surges, coastal flooding and
erosion, as well as rapid temperature changes. Teleconnection patterns
play modulating roles in storm activity, linking polar and midlatitude
climate. In addition, the tropics have been recognized as an important
source for triggering teleconnections, and may also be subject to
impacts of polar climate changes. Storms and teleconnections have
demonstrated systematic variations, leading to alterations of feedback
processes and, in turn, contributing to climate variability and change.
This session will provide a venue to present progress and new ideas on
extratropical and high-latitude storm activity, tropical or
extratropical teleconnections with the polar regions, and associated
physical feedback processes in the context of the changing polar
climate, as well as resulting extreme weather events, ecosystem-and
societal impacts.

Cycle; Modeling, Observations, and Challenges
Conveners: Elaine Matthews, Ruth K Varner, Changhui Peng,
and Paul J Hanson
Natural wetlands/open waters--the world's largest, climate-sensitive
methane source--are contributors to interannual and decadal fluctuations
in atmospheric CH4 concentrations. Uncertainties in CH4 dynamics in
wetlands derive from heterogeneity in vegetation, microtopography,
permafrost condition, hydrology, and processes governing CH4 production,
oxidation, and emission. Understanding and modeling CH4 dynamics and
distributions of wetlands/open waters is crucial to simulating methane
dynamics and feedbacks between wetlands and past, present and future
climates. We invite presentations addressing: global-to-regional
modeling CH4 dynamics in wetlands and open waters; inverse- and
climate-chemistry modeling of wetland-methane dynamics; process studies
of CH4 production, oxidation and emission; modeling of wetland
distributions; synthesis studies of CH4 fluxes and controlling
variables; remote sensing of hydrologic dynamics and vegetation
characterization of wetlands; role of wetlands and water bodies in the
global CH4 cycle through time. We welcome submissions identifying
challenges to quantifying the role of wetlands/open waters in the global
methane budget.

Conveners: Lauren M Everett, Julie Brigham-Grette, and Waleed Abdalati
The Earth's polar regions are undergoing rapid transformation--with
destabilization of the major ice sheets, loss of glaciers, and (in the
Arctic) loss of sea ice, snow cover, and permafrost. Because these
changes can have profound consequences for global society, some people
feel the scientific community must not only study current trends and
refine projections of future change, but also must consider how to
effectively communicate about and respond to such changes. Building on
the recent NRC reports on Climate Intervention, this session will
address questions such as: Will the polar regions simply "unravel" or
are there in fact any feasible interventions that could slow, stop, or
reverse any of the changes taking place? What would be needed in terms
of emissions reductions? Atmospheric carbon removal? Other response
strategies? If not, what recommendations might scientists communicate to
the public?
https://agu.confex.com/agu/fm15/preliminaryview.cgi/Session8473Session 8477: Global Eyes on the New Arctic: Impacts of Rapid Warming
on Ecosystems, Society, and Policy
Conveners: Lauren M Everett, Jennifer Ann Francis, Hajo Eicken,
and Henry P Huntington
Once considered a frozen and desolate region, irrelevant to all except
those who live and/or work there, the Arctic has recently become a
literal and figurative "hot spot" of interest to the world. Rapid
disintegration of sea- and land-ice is hampering indigenous ways of life
and disrupting natural systems while also creating new opportunities for
commerce and other human activities. This session will illuminate our
rapidly evolving understanding of the effects of system-wide Arctic
change on physical, ecological, societal, and political domains well
beyond traditional Arctic boundaries--and vice-versa.
