Wow you sure have me convinced that this isnt a totally normal fluctuation that happens every few hundred years or so.
There are no indications that such a claim is supported by the evidence.

Do you have observations to support your hypothesis?

Whats a matter did the data from 1960 to 1980 show a rapid climb ? and therefor have to be left out.

Average July through September Arctic sea ice extent 1870-2008 from the University of Illinois (Walsh & Chapman 2001 updated to 2008) and observational data from NSIDC for 2009-2011, (blue), with a fourth order polynomial fit (black solid line).
