Summary
[edit]
| Description |
English: Arctic sea ice extent in million square kilometers. Blue shading indicates the pre-satellite era; data then is less reliable. In particular, the near-constant level extent in Autumn up to 1940 reflects lack of data rather than a real lack of variation. Extends File:Seaice-1870-2007.png to 2009 using data from ftp://sidads.colorado.edu/DATASETS/NOAA/G02135/ University of Colorado Boulder, lightly munged. |
