Arctic Sea Ice: Animation of Thirty Years

Among the general boredom of reading about the latest awfully hollow “demonstration” that humans are at fault by way of exclusion (and in the process, finding the fingerprint of human-induced rise in temperature in places such as Antarctica where temperature has not risen…unless it’s the Peninsula they are referring to), here some animations of how arctic sea ice has appeared between 1979 and 2008, around October 28, according to Cryosphere Today (note: some years are missing, and for other years I had to take the nearest available image)

One could be forgiven to think the following:

  • there isn’t much of a polar ice cover “shrinking trend”, but rather a lot of expansions and contractions, plus a freakish small configuration in 2007
  • the 2008 cover is very simiar to 2000’s, apart from an ice-free area East of Novaya Zemlja
  • one can almost sea the warm water flowing in through the Bering Strait, sometimes reaching East as far as Banks Island (1987, 1998)
  • the “losses” in sea ice in the Baltic and northwestern Siberia may or may not relate to a change in data processing between 2003 and 2005

Note how different the last 3 years look, as they include the snow cover exactly when, say, the ice in the White Sea suddenly goes.
