Arctic Sea Ice Extent Compared

leave a comment »

The fact that Arctic sea ice is decreasing in extent is hardly news. What exactly that decrease looks like, however, and how it has changed during the last thirty years, can be hard to fathom from numbers and texts alone.

At the University of Illinois’ website, The Cryosphere Today, it is possible to compare satellite imagery of the frozen Arctic ice cover from 1979 (the earliest satellite photos on record) and until today. Check it out by clicking the photo below. Specify year and month in the top boxes at the site and press submit to compare the changes.
