NASA has released an animated (daily) view of the 2013 Arctic melt season, which unofficially ended on September 13th.
The animation below shows daily ice coverage (total area of at least 15% coverage) in white.

The actual minimum extent was 5.10 million sq/km. Last year's record minimum was 3.41 million sq/km, according to the National Snow and Ice Data Center (NSIDC report).
The top five lowest extents in order were 2012, 2007, 2011, 2008 and 2010.
The average date (1981-2010) of the annual Arctic sea ice extent is September 15th.
Also, the Antarctic sea ice extent reached a record high on September 18th, which ties last year's record maximum.

For the third consecutive year, a new global annual temperature record has been set, according to NOAA and NASA.
In terms of global sea ice extent, 2016 will be noted for the number of monthly low record extents that were set in both the Arctic and Antarctic regions.
Alaska had their warmest year on record by a wide margin.
Climate models may be overestimating the stability of the Atlantic Meridional Overturning Circulation (AMOC), which is one of the world's largest ocean circulation systems.
A new independent study has confirmed an earlier paper's conclusion that there was no slowdown in ocean warming over the past 15 years.
