You may care to read NASA's view, not some climate sceptic's appraisal of the study.

I did read that article from start to finish an it made for interesting reading but I don't understand the point you are trying to make.....What has happened is quite normal and there will be increases and decreases over time.
My youngest son spent 6 months in Antarctica 5 years ago....He went to Davis on the Aura Australis in October when normally this vessel can dock at that time of the year but due to the late summer ice melt the ship could not get in to port due to some 6 feet of sheet ice, so he and his team had to walk 4 nautical miles to Davis...The Aura Australis finally docked some 2 weeks later.
My point is the sheet ice can vary from year to year......It is really no big deal.
