"NPS --- predicts an ice-free Arctic by 2016"
If there is less than one million square m----- by 2019 this is an accurate prediction,
( 2016 +/- 3 )
PIOMAS November 2013
Another month has passed and so here is the updated Arctic sea ice volume graph as calculated by the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS) at the Polar Science Center: Things are getting really interesting now, with volume levels back to those of 2007, slightly above t...

"I dropped in to go totally off topic, with apologies: typhoon Haiyan is bearing down on the Philippines"
Not OT - imo
We need to keep it in perspective there is more to the story than Atlantic Basin Hurricanes
Any chance you may have seen something that implies cyclones - typhoons in the Pacific may be sucking heat out the oceans and preventing - delaying - reducing El Nino's ?
Arctic sea ice and jet stream changes
It's the most interesting and actual of all potential risks tied to Arctic sea ice loss and could turn out to be one of the surest signs of changing weather patterns. Which explains the growth in interest and research. One of the latest scientific papers on this subject, Influence of Arctic sea...
@NJSF - in the the three years I've been following this blog, it's very seldom there is a poster certain about what's going on up there.
Would you comment about whether my "graph" of Arctic Sea Ice for prediction of 2014 Minimum will have a Red or Blue Line?

Pinpointing the minimum
UPDATE September 16th: Given another uptick and the current weather forecast, I'm ready to call the minimum for IJIS SIE V1 on September 12th at 5,000,313 km2. Apparently the high was too big and the pressure gradient too low to prolong things (see below). --- This blog post should perhaps ha...
Allen W. McDonnell | September 09, 2013 at 18:36 - "Because of this energy convection effect so long as Earth has surface water to evaporate and condense at high altitude there is a limit to how warm the surface can get."

2. Would you share some links - references.

A snippet from your reference - link:
'COMPLICATED PROCESSES'
"We're trying to understand why the ice is melting so fast," said Simon Boxall of the Catlin Arctic Survey. "It's not just down to simple warming. There are more complicated processes."
The speed at which sea ice is disappearing in the Arctic has far exceeded almost all predictions and alarmed climate scientists.
------------------------------------------
Yes, we have very good indicators of how the ice "is"
When they (Catlin) release more data and the cruise of the Swedish Icebreaker Oden tabulates and more data is available, perhaps we will gain some more understanding of why most of the 'MODELS' have under-estimated rate of melting.

Record dominoes 6: IJIS sea ice extent
There are several scientific organisations that keep an eye on the Arctic sea ice cover and put out graphs to inform us of the amount of ice that is left. You can see most, if not all, of them on the ASI Graphs webpage. I expect the record on most of these graphs to be broken in weeks to come. -...

If the volcanic action results in added heat to the water with upwelling, especially from along the Mid-Atlantic Ridge North of Iceland into the Arctic via the Barents, Kara Seas, and Northern Sea Route - it's getting attention from places other than me.

Found one of the articles about Siberian River flow toward the Beaufort Sea. It has a nice picture, in FLASH, so click on the numbers, especially # 3.
Probably should be in a separate post about Arctic Ocean Circulation - will check to see what we've posted & discussed before starting one.

I don't know where it is - can't find it now, but last year ( 2011) there was an article about the warm-fresh waters from the rivers of Russian Siberia flowing as a stream across the Arctic to the Beaufort Sea. May becoming more visible.

Lodger,
Transmorgified the e-mail addy's above. Needed to know how to EDIT a post, first time and it worked. Kind of been useless for the blog lately - used to try to do some animations, but now Neven is always a step ahead of me, maybe someday I will find something positive that's not a duplication.
Because the link(s) were not activated properly, it's doubtful any "spambots" picked the addy out, because 99% of them are coded to pick up on the mailto: scheme of the HTML Anchor Tag surrounding
mailto:[email protected]
Delete this most - no way - it's what a group or team is about - you're relevant, enjoyable, and useful for me read your comments.
Cheers,

I also voted the lowest on both polls.
Mainly because of the "Jet-Stream" effects-excursions of the "Hot is hotter" and the "Cold is colder" along with reasons expressed above by fred.

Polls 2012: daily and monthly minimum

"OTOH, there is a surprisingly rather big gain of sea ice in the Sea of Okhotsk."
- - - - - - - - ! - - - - - - - - - -
Kris, This is something that I find amazing, perhaps aggravating, we discuss Arctic Ice but seem to use Northern Hemisphere 'ice-extent-area' then because Okhotsk is outside the Arctic Circle AND NOT contiguous to the Arctic Ocean nor 'Bays' - 'Seas' which are contiguous.
No Doubt Okhotsk Ice (water temperature) contributes to weather.
But, in the early stages of the Arctic Melt Season and due to the lower latitude of Okhotsk, which NSIDC-MASIE now lists as 1,142,474 sqkm when this melts out does it contribute to a very fast decrease in Ice Extent causing a lot of "oohs-aahs" about the loss of over a million square kilometers??
Saving the month-by-month MASIE data for a comparison later in the melt season.

Neven, - Thanks for including the cool video for Russian rivers putting fresh water into the Beaufort Sea. H'mnn fresher water freezes at a higher temperature than saltier water. Reason and logic to some things.
Also, of related noteworthiness is "The ARM"
http://neven1.typepad.com/blog/2010/09/the-arm.html
extending into the East Siberian Sea. Virtually enclosed by the counter clockwise circulation on it's way to Beaufort Sea.
Some things we discussed - admired - wondered about - noted a couple of years ago were worthwhile - at least to me.

Neven,
Speaking for no one except myself.
My meager donation no longer belongs to me.
It is yours "unconditionally." PERIOD !!!
What is done is done.
You must decide about any reserves in the account.
I just hope your time and health permits you to continue this BLOG to 2016 +/- 3 years, or at least another 5 years.
As I said in the Tip Jar Post
http://neven1.typepad.com/blog/2011/03/tip-jar-chip-in-and-test-topicthread.html
" if an excess is available he spends it on comforting (entertaining) someone he may have not given full and proper attention to. I've received at least the price of a theater ticket or six-pack of enjoyment here, how about you? "
Looking forward to "contributing - donating" some meager funds again next year.
Keep It Alive.
R,
Jack Taylor
