Vanishing Arctic Sea-Ice: Expect the Unexpected...

By 2020 or earlier (maybe this year) humanity will experience our first Blue-Ocean event. Next to NO sea-ice cover on the vast Arctic Ocean in September. 

Within a few years NO ice in Aug/Sept/Oct; extended to July & Nov within a few more years. NO ice year round within a decade.

As fast as sea-ice decline is (12%/decade), snow cover in spring is about twice as fast.
