Through most of June, ice extent tracked below the 1979 to 2000 average, and slightly above the levels recorded during June 2007. Warm temperatures and southerly winds led to quickly declining ice concentration in some regions, such as the Laptev Sea….

See, for instance, RealClimate’s “Sea ice minimum forecasts.”  But while the Arctic ice’s two-dimensional measurements are easier to make, the more important record is the three-dimensional one, which looks to have been set ...
