Sabbatical or not, records must be reported (like I did last year, here and here, albeit a month later).
According to NSIDC data, the Global sea ice area record for lowest minimum has just been broken, as shown on this Wipneus graph (world famous now because of what happened after September last year; see the dark red line on the right side of the graph which should be fairly easily to spot):
The extent version is about to break the record as well:
For those who still think that man-made global warming poses no risk whatsoever, that it is a hoax, I'm just going to repeat what I wrote last year:
This measure doesn't tell us all that much about the health of either Arctic or Antarctic regions, if only because the seasons move in opposite directions (nevertheless, the Global sea ice trend is down). It's just an interesting statistical factoid.
However, climate risk deniers often use the Global sea ice metric as an argument that nothing is wrong and AGW is a hoax. In other words, the recent growth in Antarctic sea ice offsets the loss of Arctic sea ice (it doesn't), even though the poles are literally worlds apart and are pretty much incomparable (except for the sea ice bit).
Using this logic, it would seem that this new record minimum means there is something wrong with sea ice and AGW isn't a hoax. I wonder how they will spin this one. If they report it to their loyal readers, that is.
Of course, they didn't report it to their readers. And they won't report this second record in a row either. They will remain quiet about this, as they always are, as if sea ice is not an integral part of this planet and its functioning.
Ask yourself why that is, what that means and whether you can trust anything they say. Be skeptical and do the right thing. Don't get swindled and then swindle others.
---
Addendum:
It looks like a big storm is about to hit the Arctic (ECMWF forecast for day 4-7, as provided by Tropical Tidbits):
959 hPa is very low, lower than the summer GACs we saw in 2012 and 2016. If this forecast comes about, the ice pack is going to get hit hard, with a lot of ice being pushed towards the Atlantic. For updates go to the 2016/2017 freezing season thread on the Arctic Sea Ice Forum.
We live in interesting times.

Looks bad with the numerical data, visually speaking even worse,(I will have something on this on the 19th). With extent hovering below 2012 many times near 1,000,000 km2. Wipneus was on the right course, September minima looked expansive for untrained eyes. There was a massive dispersion event as I reported, this new generation area calculation seems more accurate.

How low do we think it's possible for area to go? With maybe 2 million to lose in Antarctica, and not much to gain in the Arctic with the storm that's coming, I wouldn't be surprised if it went below 13 million myself.

Posted by: Neven | January 13, 2017 at 22:41
Could someone answer a question?
I understand how a loss of sea ice in summer, when the sun is in the sky for hours at a time, can cause an increase in the heat content of the ocean as sunlight is absorbed by the wine-dark sea, rather than being reflected back into space off the icecap.
On the other hand, in winter, the ice must help insulate the warm water below, preventing heat from escaping. I would expect low ice coverage in winter would cause the polar sea to lose heat energy to the atmosphere. These two effects must counteract each other throughout the year.
No doubt there are other factors at work, such as release of water vapor (a greenhouse gas) which may complicate things. Could someone please bring me up to date on how all these factors interact.
Does low ice cover have a different effect on the polar climate in winter than it would in summer?
Posted by: Elisee Reclus | January 13, 2017 at 23:24
I think part of the answer is clouds. Here's an interesting article someone mentioned at the ASIF recently:
Posted by: Neven | January 13, 2017 at 23:37
It will be coupled with a strong high in the Eurasian side and another one in Greenland. Very strong winds

Very strong winds; very weak ice. This isn't gonna turn out well IMO. The Belmont Lake Effect.

There is a very high level of attention being paid to this in the forums.
Consensus there agrees with consensus here. Weak ice, high winds, big trouble.
Now we wait and see how it plays out this weekend.
Posted by: jdallen_wa | January 14, 2017 at 05:40
-FishOutofWater here -
Open water on the Atlantic side of the Arctic allows warm water to get very close to the pole. There's a staggering thermal gradient right now between Greenland and the warm waters in the subarctic seas. This gradient helps make a storm track that moves heat and clouds into the Arctic in the dark winter months. Thus heat does not escape efficiently to space from the open water region on the Atlantic side.
Heat escaped efficiently in January through March 2013 when high pressure dominated over the pole and kept skies clear. A sudden stratosperhic warming in early January apparently increased the normal subsidence pattern over the Beaufort sea and north pole.
Thus after the open water summer of 2012 there was a strong recovery, but don't expect one this winter because of the ongoing storms.

You do have it wrong here. To correct, replace "ice" by "snow". Snow is a mixture of much air and tiny little ice granulates, hence a rather good insulator, due to the incorporated air.
As an example, for the "ice hotels" (Canada, Finland, Sweden) on the river(s) there is a day-to-day and thorough snow scrape off, in order to obtain thick and very dense solid ice (= less of air present). Where the snow hasn't been scraped off, the ice has at least 1 meter less of thickness, end of February.
Now, this winter so far the Arctic almost everywhere has been struck by intense snow flurries. Thus together with the extremely high temperatures we are alas heading right to an Arctic catastrophe.
Posted by: Kris | January 15, 2017 at 11:32
Over on the ASIF, Wipneus reports that Global sea ice extent is now record low as well.
That's the lowest value on record since satellites have started monitoring sea ice.
And it's not over yet. It could go quite a bit lower.
Posted by: Neven | January 15, 2017 at 16:27
Along these same lines...
As the recent El Nino years developed, a pool of very warm ocean water dominated in the northeastern pacific. It was tied to the ridiculously resilient ridge. The question of which of these drove the other, or wether some other factor drove the creation of either or both remained unresolved. The general belief in the research community was that the RRR caused the warm ocean.
As the El Nino faded and near La Nina conditions developed, a long band of abnormally cool water developed from the central north pacific to the northeast pacific ocean. This cold water allowed and possibly encouraged storms to flow from the Pacific into the Pacific Northwestern US. This is the opposite of what happened with the El Nino conditions. Then the storms were shunted north into Alaska and Canada and far south to Baja California. The northern branch distorted (or was distorted by, or jointly ...) the polar and continental jet streams. This in turn led to serious incursions of cold from the arctic down through the eastern US and extreme drought in California.
As the El Nino is fading, the cooling of the northeastern pacific seems to be going with it.
My question for all of you is this - How is this or how has this impacted oceanic flows into or out of the Arctic on the western side? And, how is this impacting the arctic conditions and flows?
I suspect it has either had a large effect, or its large effect has been involved in driving events in the northern and northeastern pacific, with wide ranging ecosystem impacts in addition to the weather and climate impacts.
As an added note, I have watched this region since the early 1990s. In the early 1990s, when El Nino's developed, a band of cold water developed in this area and in its twin in the southern hemisphere. When that shifted to La Nina, the equatorial Pacific went cold, and these two bands went warm. The oscillated in opposition to the equatorial temperature oscillation.
In the mid to late 1990s, this all changed. The northern band shifted to match the equatorial band (warm and warm, cold and cold). The southern band stayed as it was. The northern part of this pattern seems to be intensifying in that seeming correlation of warm to warm and cold to cold.
I don't know that that has any meaning at all. These may be unlinked events and separate oscillations. It is still curious none the less.

I think the increasing PMM and AMM are the result of convection resulting from a warmer and moister Arctic atmosphere.

Posted by: Neven | January 16, 2017 at 21:39
So the storm intensity is as forecast (959 hPa atm).
JAXA is showing a lot less ice than ever recorded for the time of year, 0.75M sq km below the 2002-15 average, an anomaly much bigger than any seen before in winter. How far will this storm impact that figure?

Al - Here's how a couple of similar storms affected the Arctic:
http://GreatWhiteCon.info/2016/11/nasa-researches-storm-frank-in-the-arctic/
This one has spent less time over the North Atlantic than those two however, but looks set to generate quite a bit of Fram Strait export over the next few days. Whilst I don't see the strong winds doing the area numbers any good it's conceivable that extent will increase on the Atlantic side of the Arctic. See for example the latest ACNFS forecast:

Hi Jim,
The biggest story is not the storm (a stand alone great event) , but sea ice drift velocity beyond 26 km/day below top cyclone winds. And especially looking away from it, 13 km a day within the traditionally densest pack. A few years back, I would of thought these speeds unbelievable in mid January. 4 km a day was considered very fast.

Hi all, long term lurker making one of my rare appearances in the comments!
Just some (hopefully interesting) observations on NSIDC Arctic sea ice extent (5 day average) numbers.
We've all been watching in horror during recent years as extent has been trending lower and lower.
I know that there are lots of graphs that show what's happening, but none-the-less, I just want to share my own observations with you (under the theory that there are never too many ways you can tell and important story!):
The following is a tally of number of days (inclusive) that the NSIDC Arctic sea ice extent (5 day average figure) has recorded a value of >2 standard deviations below the 1981-2010 average, by year. (year, total no. of days, then number of consecutive days are shown when a new record has been set for number of consecutive days under 2 std deviations).
1979 to 2003, 0 days
2004, 2 (new record, 2 consecutive days)
2005, 15 (new rec, 12 consecutive days, 37-48)
2006, 82 (new rec, 30 cons days, 74-103)
2007, 151 (new rec,122 cons days,188-309)
2008, 11
2009, 4
2010, 52
2011, 167
2012, 167 (new rec,164 cons days,163-326)
2013, 13
2014, 29
2015, 118
2016, 307
2017, 16 so far….
Also, here is a list of the top 5 periods of consecutive days under 2 standard deviations:
1. 164 days (2012, days 163-326)
2. 122 days (2007, days 188-309)
3. 101* days (2016-2017, days 281 – 16*)
4. 99 days (2011, days 163-261)
5. 94 days (2016, days 113-206)
*to date, as of day 16 2017.
It’s interesting to see that the current 101 day period is the first large period of consecutive days that has occurred in the northern winter. All the other big records were in the melting season.
Also, the last time extent (5 day average figure) was OVER the 1981-2010 AVERAGE was day 119, 2012!
Will 2017 get a 100% run under 2 standard deviations?
I know there are increasingly important other measures for the health of the ice pack, (like volume) however I still think these figures are interesting (and worrying).

A video that may be of interest... Jennifer Francis on how there is a new positive feedback in the Arctic, with Arctic amplification resulting in a wavier jet stream that brings more heat and moisture from the mid latitudes, increasing the melting, and with moisture leading to increased cloud cover in the Fall and Winter, resulting in a greater cloud greenhouse effect.

Actually, Elisee is perfectly correct. The thermal conductivity of sea ice is less than that of sea water, and therefore the formation of sea ice does provide insulation and consequently reduces the energy transfer from the ocean to the atmosphere.
Please see...
https://nsidc.org/cryosphere/seaice/processes/thermodynamic_growth.html
However, Kris is also correct in pointing out that snow is a much better insulator. Consequently, when snow falls on thin (i.e. new) ice, this serves to inhibit ice formation, as there is little scope for losing the necessary latent heat of fusion.

http://reason.com/blog/2017/01/18/2016-hottest-year-since-record-keeping-b
"2016 Hottest Year Since Good Record Keeping Began in 1880, Says NOAA and NASA"
Ok, the 2016 temperature information is finally here:
"During 2016, the globally-averaged land surface temperature was 2.57°F (1.43°C) above the 20th century average. This was the highest among all years in the 1880–2016 record, surpassing the previous record of 2015 by 0.18°F (0.10°C). ...
During 2016, the globally-averaged sea surface temperature was 1.35°F (0.75°C) above the 20th century average. This was the highest among all years in the 1880–2016 record, surpassing the previous record of last year by 0.02°F (0.01°C).
During 2016, the average temperature across global land and ocean surfaces was 1.69°F (0.94°C) above the 20th century average. This was the highest among all 137 years in the 1880–2016 record, surpassing the previous record set last year by 0.07°F (0.04°C). The first eight months of the year had record high temperatures for their respective months. Since the start of the 21st century, the annual global temperature record has been broken five times (2005, 2010, 2014, 2015, and 2016). The record warmth in 2016 was broadly spread around the world."
Ok, so separate temperatures for land & sea then they combine both. The bottom line is we have had 3 consecutive years of record breaking temperature rises above the 1880 baseline. Will we have 4 years in a row? If the arctic ice its the Gunnstaddar fifth year with a predicted new minima record, will that coincide with yet another new record high global temperature? Suppose the tale of the tape is what happens, but should be interesting with what is happening with arctic ice this winter.

Hans - See also today's Met Office press release:
http://www.metoffice.gov.uk/news/releases/2017/2016-record-breaking-year-for-global-temperature
The global temperature series shows that 2016 was 0.77±0.1 °C above the long-term (1961-1990) average, nominally a record since at least 1850. When compared with the 1850 to 1900 baseline – which is indicative of pre-industrial temperatures – the 2016 average global temperature anomaly was around 1.1 °C (see below). For comparison, 2015 was 0.76±0.1 °C above the long-term (1961-1990) average.

Thanks for the link, Jim. Glad there are still temp. differences being compared to the pre-industrial, but wonder why the goalposts are being moved to compare to the 1961-1990 period. Sure hope in future years the pre-industrial doesn't get eliminated, substituted by the more recent time period to help make the changes seem less of a concern, more politically advantageous as they help the populace perceive temp. increases as minimally incremental.
In this case the perceived temperature increase declines dramatically from a 1.1C higher than pre-industrial vs. a .1C from the 1961-1990 time period.
We all know in science it's fine to compare to different time periods as statistical analysis goes, but in my opinion we should all be aware there may be an underlying attempt to shift perception, i.e. in future years we may see the pre-industrial temperature base called obsolete and no longer quoted in mainstream articles. I hope that isn't my own paranoia, but stranger things have happened to control people's perception. For example how many times has methodology to compute GDP or unemployment been redefined?
Posted by: Hans Gunnstaddar | January 19, 2017 at 09:16
Bill, thanks for posting those record setting stats. Remember when the conjecture by the denialsphere was the Earth was cooling because all years after 1998 had lower average global temperatures? Where are those people now? Probably waiting for a cooler year than 2016 to claim the world is once again cooling - lol!
Posted by: Hans Gunnstaddar | January 19, 2017 at 09:21
@ Hans
"Where are those people now?"
Well, some of them are now desperately waiting for Solar Cycle 25 - the same ones that were desperately waiting for the current Solar Cycle 24.
"Probably waiting for a cooler year than 2016 to claim the world is once again cooling - lol!"
Jim Hunt and I were at an event in Exeter University perhaps 8 months ago, and that's exactly what Jim said would happen as soon as the then extant El Nino fizzled out.
"... wonder why the goalposts are being moved to compare to the 1961-1990 period."
Until the fabricated controversy regarding AGW gained traction, it would have been quite normal to advance the 30-year base period in decadal steps. However, NASA, NOAA and the UK's Met Office (and the CRU at the University of East Anglia) have all "frozen" their base periods. The intention was to avoid any confusion about what the value of the anomaly meant before/after any transition from one baseline period to another.
Unfortunately, these organisations have all adopted different base periods. The UK global datasets (HadCRUT, CRUTemp, HadSST) are predicated on 1961-90, whereas NASA's Gistemp numbers are based upon 1951-80
NOAA does it differently again, with their global products being based upon a 20th Century average, whilst their continental US figures are based on 1910-2000.
UAH base their satellite derived figures on 1981-2010, but (I believe) RSS use a 20-year baseline 1979-1998.

The January numbers for both the Arctic and Antarctic will be depressing. There's nothing I can see to suggest February will be much better.

Fascinating info. on baseline time periods, Bill. "UAH base their satellite derived figures on 1981-2010, but (I believe) RSS use a 20-year baseline 1979-1998." The goalposts are definitely shifting away from the earliest kept records.
On a different metric, GDP; a couple of years ago the US began adding an estimated amount for illegal street drug sales. Italy added that plus estimated sales in the red light district. As we can see there are all sorts of ways to alter numbers and perception.

"Above the 80 degree North Latitude line, temperatures were fully 4.9 degrees Celsius above average for the period of an entire year."
After reading Scribbler's latest on world temperature rise via 2016, I was looking at the extent and false color graphs. If it wasn't for the Atlantic side it would look pretty normal for this time of year. Of course that being said...

Posted by: Wade Smith | April 27, 2017 at 17:38
@ Wade
It is not letting up either. Since my last post on this thread, the NSIDC monthly global sea ice extent and area records have been broken for January, February and March. (The April area and extent figures will be out round about May 2nd or 3rd, and they will both be new monthly records.)
The rolling 12-month average for extent has dropped from 22 million sq kms (Jan - Dec 2016) to 21.7 million sq kms (Apr 2016 - Mar 2017).
The rolling 12-month average for area has dropped from 16.47 million sq kms (Jan - Dec 2016) to 16.3 million sq kms (Apr 2016 - Mar 2017).
To put this in context, the average annual extent (1979-1999) was 24.18 million sq kms, and for area was 18.82 million sq kms.
That's a 10.3% reduction in extent, and, more worryingly, a 13.4% reduction in area.
However, there was some "low hanging fruit" - especially in the Antarctic - which made it easier to break records. Last year's Antarctic numbers from April through to August were nothing special, so global records over that period are on the cards - even without any spectacular losses in the Arctic.
