    Looking at this graph, you notice step intervals of about five years, each step being downward. The first step establishes a new low, then the next go up and down in the general area of that new low. Now look at yesterdays figure for ice area;

    And the curve and direction of this graph;

    Northern Hemisphere Sea Ice Area

    How far down will this step go? And will it pause there for the next four years as it has in the past, or will it just keep going down now that it has reached this point? The old ice is almost gone, and the new ice goes so fast in the sun, that the Arctic Ocean is just getting warmer every year.

    The lowest figure of 2.91 was achieved on day 250 of 2007, day 226 of 2012, and we are at 2.98. What will the low point be this year? 2.7? Possibly 2.5? Twenty four more days to find out. And the ice is ever so thin and spread out.

    Day 248, and we are at 2.35 million square kilometers. Will the curve turn at day 250, or will it continue to go a bit further down for another week or so? It has already exceeded my worst case estimate.

    NICE ARK man.. Plenty of room for gungjah and beer.. I think I could get all the critters on board..

    Ice melts at 0degC.. When you pass that threshold in the Arctic summer -- sea ice melts.
    Can we move on? Or should I get those Ark plans from Frank??

    No, Flatulance, when the temperature hits 0 C, ice does not melt.
