Organizers of Session B07, "High-Latitude Climate Feedbacks and Their
Interactions," announce a call for abstracts. The session will be
convened at the American Geophysical Union (AGU) Fall Meeting, 14-18
December 2009, in San Francisco, California.

Climate feedbacks--the modification of climate by processes that
themselves change with climate forcing--is a central problem in global
change studies. Boreal and arctic ecosystems exhibit high carbon density
and are projected to experience large climate changes in the coming
century, making the identification and quantification of potential
feedbacks from these high-latitude ecosystems essential for future
climate projections. High-latitude feedbacks include changes in
permafrost thaw, wildfires, forest, and shrub-land productivity and
range expansion, albedo, soil responses to changing climate, and methane
clathrates. These processes are not only poorly modeled but frequently
interact; for example, increased forest fires change forest age
structure, albedo, atmospheric aerosol levels, and soil temperatures.

This session aims to present and compare the magnitude, climate forcing
potential, and interactions among high-latitude climate feedbacks.
Session organizers welcome submissions derived from field and modeling
studies, terrestrial and marine environments, and scales ranging from
the stand to the globe.

The abstract submission deadline for this and all other sessions is
Thursday, 3 September 2009, at 11:59 pm Eastern Daylight Time. To submit
an abstract, you must enter the first author's current AGU member ID and
password at: http://agu-fm09.abstractcentral.com/.
