When, last year, we asked the NSIDC's Walt Meier why the center chose to present data showing only one of the two measures of Arctic ice cover that they collect (respectively known as «extent» and «area»), when the presentation of both would perhaps reflect more realistically the complexity involved in taking such measurements (let alone using them to make predictions,), he told us:

The long term decline in Arctic sea ice is continuing, with satellite data showing the third lowest February ice extent, in records which began in 1979.
