Reconciling sea ice models with reality
The Arctic has been losing summer sea ice fast. At the end of the melt season in September 2008 the ice extent was barely above its record low of 2007, even after a much cooler summer. Most climate models did not anticipate the pace of this ice disappearance and still can’t replicate it. And as shown in the figure above, the futures projected by models are all over the map.
