Satellite observations show that Arctic sea ice extent has declined over the past three decades [e.g., NOAA magazine, 2006]. Global climate model experiments, such as those conducted at NOAA’s Geophysical Fluid Dynamics Laboratory (GFDL), project this downward trend to continue and perhaps accelerate during the 21st century.
