On September 13, Arctic sea ice reached its likely minimum extent for 2013. The minimum ice extent was the sixth lowest* in the satellite record, and reinforces the long-term downward trend in Arctic ice extent

Saying a huge jump up 'reinforces' the downward trend is outrageous spin. 

 

It's the fact that it was the 6th lowest on record that reinforces the long term downward trend.

A small fall on the NSIDC extent of 18.3k. This takes us to 46k off the minimum, so while the official 5 day average minimum value (which NSIDC use) is safe, the daily minimum isn't quite out of the woods yet.

All we can say for this year looking at it in isolation is

 

In reality this  year doesn't reinforce the long term downward trend .

 

This years shows a increase on last year of 60% the best in the last 6 years but still runs well below the long term average extent/volume.

But when talking about the long term trend, you can't look at a single year in isolation!

Really think this year would of been even higher if it was not for well below average in the Atlantic side of the Arctic, just imagine if we had ice like in 2009 in the Atlantic side of the Arctic, we may of been approaching 2006 levels! Of course, for that there probably would of been more Northerly winds therefore less ice on the Pacific side of the Arctic but it shows that whilst 2013 has the most Northerly retreat of the ice on the Atlantic side on record, the ice in the central basin is probably the most since 2006? 

 

I find the thicknesses charts interesting as they were down during August and now look completely different(I'm sure the ice was thinner before it went down) but the very low ice thicknesses area does look valid though. 

 

If the Atlantic side of the Arctic starts to cool down rapidly into October and November, then I would not be surprised too see extent levels being pretty high compared to recent years, of course, if we have Southerlies then we could see a similar trend to 2009, be interesting too see what happens though.

An increase of 88k on the NSIDC extent yesterday.

 

I think we can call the melt season over now. Quite an interesting one it was too!
