Arctic sea ice extent "recovering fast" (again!)

Perhaps Sue will cover this on the main blog, but if not, then it's worth mentioning that it's the time of year again when the Deniosaurs celebrate the latest 'recovery' of Arctic sea ice extent.  WUWT, aided and abetted by Paul Homewood, is leading the charge with the following tales of the great 2016 rebound:

"- The earliest minimum since 1997 – shows how cold it is there
- This year extent was 22% above 2012, despite two massive storms
- Thickness is way up on 2010 and 2011
- Already extent is above 2007, as well as 2012, for this date
- We are looking at one of the fastest ice growths in September on record"

Every point made here falls into the 'one side of the story' category.  They can all be countered with a single "but"...

- 'The earliest minimum extent since 2007' but the second lowest extent on record and well within the normal range of minimum extent dates.  Anyway, it's not unusually cold there.  Even AW links to the DMI chart showing the Arctic is currently (as of 15 Sept) anomalously warm.


- 'Extent 22% above 2012 despite two massive storms' but summer conditions that were generally unfavourable for ice melt go unmentioned.

- 'Thickness is way up on 2010 and 2011' but way down on 2014 and 2015.  According to Neven, "During August 2016 more sea ice volume was lost than during any other August in the past decade."



- 'Already extent is above 2007, as well as 2012, for this date' but it's only been 5 days since minimum extent was reached and in 2007 and 2012 ice extent minimum wasn't even reached until 14 September!

- 'We are looking at one of the fastest ice growths in September on record' but, as was mentioned above it's only been growing for 5 days!!  What we're looking at is a five day snapshot.

Ah, the fickle world of the deniosaurs.   They can simultaneously deny the validity of scientists extrapolating from a decades long downward trend in sea ice minimum extent values, whilst themselves happily extrapolating from a 5 day 'trend' in sea ice extent that - one that happens to be in the direction they like. 

(Hope the images and link were posted correctly.)
