Polar ice decline.

After the disastrous decline in the Polar sea ice in 2012 all eyes are on this seasons minimum.
With a historical average minimum of around 15 million square kilometres, last year dipped to 3.5 million. This year we are starting with very thin ice and some areas are deeply fractured so it is not a good start. PIOMAS  http://neven1.typepad.com/blog/2013/05/piomas-may-2013.html#more  is forecasting a level of 3 million square kilometres which could almost be considered ice free. 
If the lack of ice really is having a serious affect on the weather in the Northern hemisphere as has been reported by Jennifer Francis and others then Europe, Russia, China and the USA are going to have a very difficult time. The UK has hardly reached 15C and the USA has deep snow in the centre and hot, dry and windy weather with wild fires in California. 
Climate change is not linear and predictable and apparently its not in the distant future either.

An interesting palaeoclimatology history from Penn State Uni, the interest being that the Climate of the Southern hemisphere was greatly affected by the North in the past. Is this what is happening now ? First the Arctic - then rapid catch up in the Antarctic: It is an interesting discussion.
