Washington post article "2C Beyond the Limit - Dangerous new hot zones are spreading around the world".   Some pretty nice graphics

A Washington Post analysis of multiple temperature data sets found numerous locations around the globe that have warmed by at least 2 degrees Celsius over the past century.

Arctic sea ice / Expedition to drift through arctic ocean

these scientists and several hundred others will launch the largest Arctic research expedition in history: a 12-month, $134 million, 17-nation effort to document climate change in the fastest-warming part of the globe.

I have been Looking at that large area of remaining ice in the Beaufort Sea.   This is not the first time we have seen such a separation or near separation of an area of ice from the main pack.
I think we will see more and more of these separate ice patches in the future.

I am no longer envisioning the ice would retain a large central pack with clear fronts on all sides.   Where long term the fronts would advance and the central pack would shrink,  until the remaining ice is piled up along Greenland and Canada.

Instead I would propose that over years, we will see this central pack slowly dissolve into an increasing number of separate areas or concentrations of ice.    Sort of like the breakup of a super continent into smaller, separate continents. 

Eventually we will be tracking individual patches, for their own extent, area and concentration.   Tracking the ups and downs of each, as we watch the sub-packs fade on their own schedules.

Thus the Blue Ocean Event will come when the few remaining scatterings of ice melt below the combined threashold.   On that day there could be 3 or so separate areas of remaining ice in an otherwise blue ocean.   And those remaining areas of ice could be anywhere in the Arctic Ocean.
