"If someone claims Arctic Sea Ice is in a death spiral, you can mention that right now 2013 is the 7th lowest and not the lowest.
And that 2013 has even more ice than 1989 at this point in the year.
Lowest 7 = 2006 2004 2011 2007 1989 2005 2013
And that Extent is within one standard deviation of the 1981 – 2010 mean. And only 340,000 sq km below the mean which is about 2.5%."
