“The twelve lowest sea ice extents of the satellite era [since 1979] have all occurred in the last twelve years.”

One year by itself tells you nothing. Just because we didn’t break the 2007 and 2012 records this year doesn’t mean the problem is over. Look at the overall trend.

See for yourself how this year’s average September ice extent compares to other years.
