Where did you get the 580,000 number? According to NSIDC website the August 2013 ice extent was 2.38 million square kilometers (919,000 square miles) above the record low August extent in 2012.<quoted text>
The Mail, Brain_Dead? This is where you get your science?
They say almost a million square miles more which they can say because they rounded off 580,000 to "almost a million square miles".
Note that even they admit to 2012 being a record low.
And still, you do not get it, that ice extent is a different thing from ice mass, particularly in relation to the remaining "old ice", that which is thicker than one or two years will give you.
But we know, that for you, it's any port in a storm....
