Dear Colleagues,
I would like to remind you that the deadline to submit abstracts to the
following session at AGU is Sept. 10, 2359 UT (7:59 pm EDT). Please get
yours in in plenty of time. We look forward to an interesting session.
Alan Robock
We would like to invite you to contribute to our Union session for the Fall AGU
Meeting, December 15-19, 2008:
U06: Geoengineering as a Solution to Global Warming?
Geoengineering schemes have been proposed to temporarily counteract
global warming, as nations work to implement preferred mitigation strategies -
namely, reductions in greenhouse gas emissions. While many general
geoengineering concepts have been put forward in recent years, no concrete
proposals that address the range of scientific and social issues related to
such activities have been submitted for consideration. This session focuses on
climate modification through the manipulation of solar energy input to Earth
via processes internal or external to the atmosphere. Several specific schemes
along these lines have been investigated in a preliminary way in terms of basic
processes. Examples include the injection of reflective aerosols into the lower
stratosphere, seeding of marine clouds to modify their albedo, and placement of
mirrors beyond the atmosphere to deflect incoming sunlight. However, it is now
desirable to ask more detailed questions regarding implementation and expected
outcomes. Accordingly, this session invites papers describing the most recent
scientific and engineering results on solar radiation control strategies.
Particularly sought are papers describing the feasibility, risks, costs, policy
implications, and ethical and political dimensions of global radiation
intervention, but only if the analyses are developed on the basis of sound
scientific findings. While proposed engineering projects may assume regional
or global scales, all of the local, regional and worldwide impacts are open to
consideration, including predictions of changes in climatological, biological,
and social parameters. Presentations of well-developed designs for laboratory
or field experiments relevant to the topics outlined above are also welcome.
We remind you that AGU allows only one contributed presentation at the
meeting, and one additional presentation if you have an invited talk. The
deadline for submission of presentations is Sept. 10. Please submit your
abstract at <http://submissions3.agu.org/submission/entrance.asp>
