Arctic Ice Retreating More Quickly than Computer Models Project - Multimedia Gallery
(animations, illustrations)
Arctic sea ice is melting at a significantly faster rate than projected by even the most advanced computer models, a new study concludes. The research, by scientists at NCAR and the University of Colorado's National Snow and Ice Data Center, shows that the Arctic's ice cover is retreating more rapidly than estimated by any of the 18 computer models used by the Intergovernmental Panel on Climate Change (IPCC) in preparing its 2007 assessments. | News Release

Apr. 17, 2007

Geo-Engineering Climate Change with Stratospheric Sulfate Aerosols
(49 minutes)
Rasch discusses the impact of injecting a precursor of sulfate aerosol into the middle atmosphere, where it would act to increase the planetary albedo and thus counter some of the effects of greenhouse gas forcing.
