The observable fact that both Arctic and Antarctic sea ice extents are at or beyond long run seasonal averages would lead me to be sceptical of your claim.
"Arctic sea ice extent is at or beyond long run seasonal averages"?
Are you blind?
The last figure, as of posting (day 284) is 6.063 million km^2. The 1981-2010 average for the same day is 7.684 million km^2. What's 1.6 million km^2 between friends? It's just inside the 2sigma region, but only just.
The Antarctic is currently more or less at the 1979-2008 mean, 14.835 million km^2 vs a mean of 14.830 million km^2. That's likely to be around its high point, and is less than it was last year.
