No, Arctic sea ice decline has been exponential. In addition, old ice has been replaced by much newer, thinner ice to the point that algae is now growing underneath the surface of the ice. Just this winter, a new record low was recorded.

Arctic temperature amplification from exponentially declining sea ice and spring snow cover are the strongest feedbacks in our climate system today. The average albedo (reflectivity) of the Arctic region has decreased from 52% to a present day value of 48% over 3 or 4 decades. The increased absorption of energy in the Arctic has increased the temperature at high latitudes at rates up to 6 to 8x the global average temperature change. The reduced temperature difference between the Arctic and equator has reduced the west to east speed of the jet streams causing them to slow and become wavier and more fractured, and directly causing a large change in the statistics of our global weather. - Link

...Critics have said that previous calculations of ice loss seemed too rapid, and questioned their value, the researchers said. But the new study shows the ice may be thinning at an even faster rate than the calculations showed, the researchers said.

“At least for the central Arctic basin, even our most drastic thinning estimate was slower than measured by these observations,” co-researcher Axel Schweiger, a polar scientist at the University of Washington Applied Physics Laboratory, said to to LiveScience. - Link

...An 'exponential decline' in sea ice - covered up by the IPCC

According to the WMO, Arctic sea-ice extent reached its annual minimum extent on 17 September 2014, at just a patch above 5 million sq.km - the sixth lowest on record, according to the National Snow and Ice Data Center.

"There is quite a lot of natural variation from year to year", he says. "But the downward trend is clear - an exponential decline. It is what you expect from positive feedback, and exponential decline is a better fit to the data than a linear decline."

And he insists that his conclusions are firmly founded on peer-reviewed science, specifically observations of sea ice thickness confirmed by Cryosat-2, together with satellite imagery. Worse, he alleges, the IPCC has tampered with the raw data in order to downplay the dangers the world faces... - Link
