This movie is to show the complete 30 year history of the NSIDC satellite derived arctic sea ice extent in a single video. Brown is land, black is shoreline, blue is water except for the large blue dot in the center of the plot. The movie plays double speed at the beginning because the early satellite collected data every other day. Youll see the large blue circle change in size flashing back and forth between the older and newer sat data just as the video slows down.

After staring at the graphs above you think you understand what is happening as ice gradually shrinks away. Well the high speed video shows a much more turbulent world with changing weather patterns in 2007 and 2008 summer blasting away at the south west corner of the ice. Ive watched it 20 times at least, noticing cloud patterns (causing lower ice levels), winds, water currents and all kinds of different things. Im not so sure anymore that were seeing a consistent decline to polar bear doom, with this kind of variance it might just be everyday noise.

Note that despite some mainstream media reports, our Arctic Sea ice has not melted away, but comes back every year as it has done for millennia..This is the normal season cycle.
