From my chair, it looks to me like there will be zero sea ice in the Arctic by September 30th of this year 2012.
The massive cyclone in the Arctic of unprecedented size has been chewing up the sea ice for the last week and it looks like over 1 million square km has been lost. A few more cyclones there will finish it off completely.
My presentation on the link below needs polishing, is quite technical in places and is mostly my compilation of blogs and data and comments from other scientists, engineers, and lay-people. It is mostly in chronological order as the storm has progressed.
