Dear Colleagues, We invite abstract submissions for the following biogeoscience session of the Fall 2009 American Geophysical Union meeting:
B07: High-Latitude Climate Feedbacks and Their Interactions Please find a link and description of this session below. The abstract submission deadline is September 3. Information can be found at http://www.agu.org/meetings/fm09/index.php All the best, Ben Bond-Lamberty Phil Camill ___ http://www.agu.org/meetings/fm09/program/scientific_session_search.php?show=detail&sessid=164 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 shrubland 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. We welcome submissions derived from field and modeling studies, terrestrial and marine environments, and scales ranging from the stand to the globe.
