So there's 'only' a 10% ice loss since the 1980s, correct? That's way less than I would assume based on the alarming messages.I wish that Geron and Juan could report on ice areas and extents as large as they were in the 1970s.....

Thanks, pleun.At maximum sea ice extent /area change is of thin ice in peripheral seas. Thus a small variation in winds / temperatures can halt or increase sea ice extent enough for an early or late maximum date.
Should have looked closer.
Wow, the date is all the way from Feb 15 to 31 Mar. Why the wide variation, different air masses passing over the Pole? I don't recall, does the thaw have such a wide range of ending dates?

Note that for a month or so after extent/area maximum, the Arctic Ocean is damn cold, and ice thickness continues to increase at a greater pace than ice is lost in the periphery. Hence ice VOLUME maximum is in April.
I wonder if this is the time when more ASI implies that the ocean loses less heat. The worst September minimums seem to have more ice now. But I never know what is going to happen in September. So let's wait and see.[ADS NIPR VISHOP (JAXA)] Arctic Sea Ice Extent.

Wow, these extent gains are seriously impressive! I wonder if they'll translate to a less worrying spring and summer this year.Feels like 2012/2013 all over again. Increased bering sea ice can't be a bad thing though, will help protect the chukchi. On the other hand the continents will also heat up faster if there is reduced snowcover/lake ice.

For 2.2.2020, the NSIDC northern hemisphere sea ice extent value is 14.42 millions of square kilometers. This is an increase of 116,000 square kilometers from the previous day.
NSIDC sea ice extent is in 15th place for the date. 2020 has more sea ice extent than 2004, 2005, 2006, 2007, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, and 2019 for the date.
The next 4 closest years are 2009, 2008,...
In other words, the 17 years with lowest sea ice extent for the date are among the first 20 years of the 21st Century. A clear perspective of long-term trend of global warming, thanks weatherdude.

Take into account that this is all based on data from 1979 and on. There is no real data from before ( there are some very bad satellite pictures from 1975'ish). Before that there is reported anecdotal data from explorers and locals that in some cases point to low arctic ice.

And this is happening with a polar vortex on steroids and the Arctic Oscillation in an all-time, record-breaking maximum. What gives? Textbook says the Arctic should be very cold and the ice pack expanding.

Is this a kind of a bounce-back, i.e. a negative feedback loop, or just an expression of natural variability?
The freezing thread is where one hopes to find the whys and wherefores of what is happening. You might be lucky if you take a look.

The latter IMHO but there are others here who can offer more.

I think it should be possible to put your Excel files on an usb stick and take them whereever you want.
I have my whole backup + files+ plug-in running linux/GNU system on an usb stick. If I put it in another computer, it will start up with my system and my desktop with my important files. In effect I carry my whole system wth me. This usb stick is behind a zipper in my wallet.

Sea ice extent for February 2020 tracked below average, ranking as the thirteenth lowest monthly average in the satellite record. A brief pause in ice growth in the middle of February was related to the regional wind pattern. As has been the case for the past several months, the Arctic Oscillation was in a persistently positive phase. This manifested as unusually low sea level pressure over the Atlantic side of the Arctic Ocean and high pressure over Eastern Eurasia, extending eastward into Arctic Canada.

The last days saw a slight increase in extent, and massive losses in area. Will these curves follow different directions or is a convergence ahead?Convergence, once CAPIE drops sufficiently.

Thought I would find out what CAPIE is, and lo & behold, below is an extract from a post by Neven from August 2012 - https://neven1.typepad.com/blog/2012/08/new-capie-record.htmlThe last days saw a slight increase in extent, and massive losses in area. Will these curves follow different directions or is a convergence ahead?Convergence, once CAPIE drops sufficiently.
CAPIE stands for Cryosphere-today Area Per IJIS Extent, and it tells us something about the compactness (official scientific term) of the ice. It all revolves around the different definitions for sea ice area and sea ice extent, which are two ways of calculating the total ice cover. The NSIDC explains it well:
Area and extent are different measures and give scientists slightly different information. Some organizations, including Cryosphere Today, report ice area; NSIDC primarily reports ice extent. Extent is always a larger number than area, and there are pros and cons associated with each method.
A simplified way to think of extent versus area is to imagine a slice of swiss cheese. Extent would be a measure of the edges of the slice of cheese and all of the space inside it. Area would be the measure of where there is cheese only, not including the holes. That is why if you compare extent and area in the same time period, extent is always bigger. A more precise explanation of extent versus area gets more complicated.
Extent defines a region as “ice-covered” or “not ice-covered.” For each satellite data cell, the cell is said to either have ice or to have no ice, based on a threshold. The most common threshold (and the one NSIDC uses) is 15 percent, meaning that if the data cell has greater than 15 percent ice concentration, the cell is considered ice covered; less than that and it is said to be ice free. Example: Let’s say you have three 25 kilometer (km) x 25 km (16 miles x 16 miles) grid cells covered by 16% ice, 2% ice, and 90% ice. Two of the three cells would be considered “ice covered,” or 100% ice. Multiply the grid cell area by 100% sea ice and you would get a total extent of 1,250 square km (482 square miles).
Area takes the percentages of sea ice within data cells and adds them up to report how much of the Arctic is covered by ice; area typically uses a threshold of 15%. So in the same example, with three 25 km x 25 km (16 miles x 16 miles) grid cells of 16% ice, 2% ice, and 90% ice, multiply the grid cell areas that are over the 15% threshold by the percent of sea ice in those grid cells, and add it up. You would have a total area of 662 square km (255.8 square miles).
If we divide area by extent, we get an idea about how spread out the ice pack is or not (which is determined by wind patterns). When the ice pack is compact, for instance during winter, all the 'holes in the cheese' freeze over, and so the area and extent numbers come very close, and CAPIE oscillates around the 95% mark.
At the start of the melting season melt ponds fool satellite sensors into thinking that there is open water where there is none (which get calculated for area, but not for extent). This makes CAPIE go down. As the melting season progresses, melt ponds become less and less of an influence because they drain, or the ice floes they are on break up.

And just a reminder about why I use NSIDC Area data, not extent....which means to me that every single grid cell in all of the seas is covered by at least 15% of ice.

First analysis of the sea ice extent - relative area wise - of this melting season. Last 11 days Mar 15- Mar 25, 2020.The graphs show the same.
As gerontocrat correctly wrote, it all depended on three seas:
St Lawrence - 69%
Bering - 36%
Okhotsk - 16%
Small and negligible losses (-1 to -4%) in Baffin, Beaufort and Chukchi Seas
Small and negligible gains (+1 to +4%) in Kara, Laptev, Barents and Grønland Seas
The rest was more or less constant.

Is there any explanation why Baffin Sea Ice is so much thicker in average this year and 2019 in comparison with the 2000s or 2010s?In principle: Very thin ice gone away, so only normal ice remains. But in reality, I think there is some persistent problem with Baffin Bay volume numbers.

Anywhere there is a list of the lowest September minima? I would think that the 2012 minimum would be a good level for a Do Not Exceed point, similar to Paris 2˚C, since it may have exacerbated Hurricane Sandy. I am curious how close a "normal" year is getting toward that.Table attached (NSIDC Extent (5 day trailing average)). Not that sticking up a sign "Do Not Exceed" is going to be a lot of use.

In the graph are the today's 25 lowest years.
Highlighted the 4 years with September lowest min (2012, 2019, 2016, 2007) & 2020.
P.S. My guess is that this increase is not good. We will have to check NSIDC area data (posted later by Gerontocrat). I think that the ASI is losing concentration, that at the end will generate more contact between the ice and the ocean water.

Ktb,
thank you for that update - really appreciated that.
Has there ever been a green "TRUE" in your column "Are we on track?" since you started your evaluation?
NSIDC - PERIPHERAL ARCTIC SEAS Area Analysis in Jaxa Format as at 30th April 2020
Peripheral Arctic Sea Ice Area reached a its maximum in early March at well above the 2010's average, and from then has declined very quickly indeed to well below the 2010's average.
Area loss from maximum is 1.71 million km2, some 0.64 million km2, 60%, greater than the average of the last 10 years of 1.07 million km2.
At 30th April, 2020 sea ice area is 2ndd lowest, just 25k km2 more than 2016.
Average remaining melt from now would give a minimum value for the High Arctic sea ice area of ZERO km2,but it seems the long right tail of the Gompertz curve rules that a bit if ice will remain at minimum..

It is 1030 am. & still no JAXA data - patience is a virtue?
I have moved two good posts to the melting season thread where they fit better, but then realized a part was pertinent here:Quite right, Oren - it's just that they get so ratty on the melting thread. Meanwhile - NSIDC Area DataIt is 1030 am. & still no JAXA data - patience is a virtue?

152k extent loss fro the 14th May. Is this record for May or at least the first half of May?

Sorry, I was listening to Radio4 talking about what our Govt is doing about Covid-19.No offence meant I did read your post. Nevin's spreadsheet gave me a better read on what I was looking for.152k extent loss fro the 14th May. Is this record for May or at least the first half of May?Why do I post? Read it.

Another look at NSIDC Area data.Moreso than extent, this is the metric I will be watching most carefully over the coming months.
NSIDC Total Area Analysis in Jaxa Format as at 17-05-2020 :- 10,624,423 km2
Area loss from maximum this season 2.74 million Km2, 0.45 million (20%) less than the average of 2.29 million km2.
Average melt from now would give a minimum of 2.73 million km2, 0.48 million km2 greater than the record low 2016 minimum of 2.25 million km2.
Area loss from maximum this season 2.74 million Km2, 0.45 million (20%) less than the average of 2.29 million km2.
