The year 2007 was significant for scientists, policymakers, and citizens investigating climate change and its impact on our planet's future. That year marked the release of a major report produced through global cooperation, the free exchange of ideas, and thorough scientific investigation. This multimedia gallery supports discussion of the report and current climate research.
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.
A set of six microsatellites, launched in April 2006, is probing the atmosphere in ways that have been impossible with previous observing systems. COSMIC (Constellation Observing System for Meteorology, Ionosphere and Climate) can boost the accuracy of forecasts of hurricane behavior, significantly improve long-range weather forecasts, and monitor climate change with unprecedented accuracy.
