[FONT=&quot]Neven cautions newbies that predicting Arctic ice melt is notoriously difficult, and that things may not always be as bad as they seem: “I’ve been in contact with David Schroeder and he has confirmed (or rather his model [has confirmed]) that this year (again) there is lesser melt pond formation than in years with record low minimums,” he wrote on June 12.[/FONT]
[FONT=&quot]Fewer melt ponds early on, Schroeder says, might mean less extreme melt by September.[/FONT]
[h=3]Following the ice[/h][FONT=&quot]The Arctic melt season typically begins in May, and over the course of the summer months, builds in intensity toward a day — always, so far, during September — when the Arctic sea ice minimum is reached, marking the ice cap’s smallest extent for that year.[/FONT]
[FONT=&quot]Since 2007, Arctic sea ice minimums have been dropping precipitously, and the ice is now declining at a rate of 13.3 percent per decade, relative to the 1981 to 2010 average. According to Arctic Sea Ice News, last year’s sea ice minimum was a near statistical dead heat with the second lowest ice record minimum, set back in 2007, when the Arctic ice covered only 1.60 million square miles (4.155 million square kilometers) in September. The lowest sea ice extent recorded to date came in 2012 when extent (usually defined as the area of ocean where there is 15 percent or more floating sea ice), fell to 1.31 million square miles (3.387 square kilometers).

Yes but of course the blog you are relying on is totally unbiased! There is very little new under the Sun, literally!

NASA

"In 2016, NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) in Boulder, Colorado, reported that year’s maximum as the lowest in the satellite record, and 2015 as the second lowest. An update to NSIDC’s Sea Ice Index in summer 2016 changed the sea ice extent numbers slightly, making the 2015 Arctic maximum extent a bit smaller than the 2016 maximum extent. This change did not affect the overall trend toward ice loss: The Arctic’s sea ice maximum extent has dropped by an average of 2.8 percent per decade since 1979, the year satellites started continuously measuring sea ice."
 
On August 21, 2017, ice extent stood at 5.27 million square kilometers (2.03 million square miles). This was 1.82 million square kilometers (703,000 square miles) below the 1981 to 2010 median extent for the same day, and 804,000 square kilometers (310,000 square miles) and 221,000 square kilometers (85,000 square miles) above the 2012 and 2007 extents for the same day, respectively.

Ice retreat from August 1 to August 21 averaged 73,000 square kilometers (28,000 square miles) per day. This was faster than the 1981 to 2010 average rates of ice loss of 57,300 square kilometers (22,000 square miles) per day, but slower than in 2012, which exhibited the fastest rate of ice loss compared to any other August in the passive microwave satellite data record.

Here is the HADCRUT4 data plotted from Jan 1920 to Jan 2016. The Arctic is no warmer now than in the 1930-40s.
