And we drop below the 2004 minimum into 19th place.

Trivia: from tomorrow (Aug 19), until September 19, the lowest 15 years are the most recent 15 years
(going on 16 years, assuming 2022 stays below 2005)

[gerontocrat]

The plume of projections of the JAXA se ice extent minimum show that remaining sea ice loss give a range of the minimum from just over 4.5 million km2 to over 5 million km2.

This suggests it is unlikely that the minimum will be lower than 2021 and will be possibly above 5 million km2. It is hard to reconcile that with the extreme amounts of very low concentration ice at very high latitudes.

I will see what the PIOMAS data has to say.

And we drop below the 2004 minimum into 19th place.

Trivia: from tomorrow (Aug 19), until September 19, the lowest 15 years are the most recent 15 years
(going on 16 years, assuming 2022 stays below 2005)

Attached is the most recent NSIDC sea ice data.  I have attached estimated extents based on gerontocrat's past years averages.  Additionally, the minima of the 21st century are shown where they would appear roughly on the curve. We pasted 2001 over a week ago, and are zeroing in on the minima of 2000 and 2003.  As stated previously, 2022 will likely pass 2005, but after that it is a crap shoot.  While the past average takes us to around the same level as 2013 and 14, anything can happen over the next month.  If melt increases, this year could surpass 2021, which stands currently as 12th lowest.

less is more ..

[Phil.]

"Average remaining extent gain (of the last 10 years) would produce a maximum in March 2022 of 14.39 million km2, 0.52 million km2 above the March 2017 record low maximum of 13.88 million km2, which would be 10th lowest in the satellite record"

I think we're still in the loss phase?  Wrong template?  :-)

Just below the 2005 minimum and counting,at least 16th place in the bag!

Just below the 2005 minimum and counting,at least 16th place in the bag!

Below all the minima before 2007, yet (for now) above all the minima since

Oh, and at least one person was too high on the August JAXA poll. We're now into the 4.75 - 5.25 km² zone

JAXA ARCTIC SEA ICE EXTENT:  5,173,639 KM2 as at 25-Aug-2022

- Extent loss on this day 70k, 22 k more than the average loss on this day (of the last 10 years) of 48k,
- Extent loss from maximum on this date is 9,220 k, which is 269 k, 2.8% less than the 10 year average of 9,489 k.

- Extent is at position #11 in the 44 year satellite record

- Extent is  28 k LESS than 2021,

_____________________________________________
On average 94.8% of extent losses from maximum to minimum done, and on average 20 days to minimum

Projections. (Table JAXA-Arc1)

Average remaining extent loss (of the last 10 years) would produce a minimum in September 2022 of 4.65 million km2, 1.48 million km2 above the Sept 2012 record low minimum of 3.18 million km2, and 13th lowest in the satellite record

How much of this recent accelerated sea ice extent loss is real melt and how much increased concentration from sea ice drift?

from NSIDC (5-day trailing average) data

The area and extent graphs show losses stalled in the peripheral seas - entirely down to ice in the Greenalnd Sea NE of Greenland has not melted out this year. In 2021 ice in the Greenalnd sea was at a record low.

The High Arctic graphs show 2022 extent currently well below that in 2021, while the area graph shows the opposite.
