Which is the best answer to Sep-2012 ASI lost (compared to 1979-2000)?
50% [NSIDC Extent] or
73% [PIOMAS Volume]

Volume is harder to measure than extent, but 3-dimensional space is real, 2D's hide ~50% thickness gone.
-> IPCC/NSIDC trends [based on extent] underestimate the real speed of ASI lost.

JAXA ARCTIC SEA ICE EXTENT:  9,141,695 KM2 as at 01-Jul-2022

- Extent loss on this day 51k, 51 k less than the average loss on this day (of the last 10 years) of 102k,
- Extent loss from maximum on this date is 5,252 k, which is 74 k, 1.4% more than the 10 year average of 5,178 k.

- Extent is at position #10 in the 44 year satellite record

- Extent is  191 k MORE than 2021,
- Extent is  325 k MORE than 2020,
- Extent is  227 k MORE than  2019,
- Extent is  252 k MORE than 2016
- Extent is  200 k MORE than 2012
- Extent is  83 k MORE than the 2010's Average
_____________________________________________
On average 51.7% of extent losses from maximum to minimum done, and on average 75 days to minimum

Projections. (Table JAXA-Arc1)

Average remaining extent loss (of the last 10 years) would produce a minimum in September 2022 of 4.31 million km2, 1.13 million km2 above the Sept 2012 record low minimum of 3.18 million km2, and 8th lowest in the satellite record

Looks like that maybe high sea ice losses about to switch from Area to Extent


Apart from the Central Arctic & the CAA , High Arcrtic area losses slowed or in reverse. Some graphs attached.

A century break and a little bit above average sea ice loss for this day.
Perhaps a sign that all this stormy weather in the central Arctic and warmth in the CAA is translating into measurable sea ice loss?

from NSIDC data - some Area graphs

The CAA sea ice area graph is interesting. Every year there is a hiatus at bout this time of year.
It was explained to me that area loss in June is mostly surface melt - pomding, and when they drain the sensors detect sea ice gain. ( I think that's right)

I have been waiting for the year when melt is fierce enough to blast through this hiatus. Maybe this is the year?

The Kara region is managing to keep its distance below the 2010's average, as is the Greenland Sea

And the Barents sea has finished its melting season with a flourish below the 2010's average

Volume is harder to measure than extent, but 3-dimensional space is real, 2D's hide ~50% thickness gone.
-> IPCC/NSIDC trends [based on extent] underestimate the real speed of ASI lost.

On average 63.1% of Area losses  from maximum to minimum done, and 68 days to minimum

Projections.

Average remaining area loss (of the last 10 years) would produce a minimum in September 2021 of 3.22 million km2, 0.97 million km2 above the Sept 2012 record low minimum of 2.25 million km2.

As far as NSIDC 5-day trailing average area and extent data is concerned, there is but one word to say on the melting season so far - SLOW

[ADS NIPR VISHOP (JAXA)] Arctic Sea Ice Extent.

July 6th, 2022:
      8,775,668 km2, a drop of -60,209 km2.

For comments, see the first post in this thread.
Source: https://ads.nipr.ac.jp/vishop/#/extent.
Which is the best answer to Sep-2012 ASI lost (compared to 1979-2000)?
50% [NSIDC Extent] or
73% [PIOMAS Volume]

Volume is harder to measure than extent, but 3-dimensional space is real, 2D's hide ~50% thickness gone.
-> IPCC/NSIDC trends [based on extent] underestimate the real speed of ASI lost.

I added the monthly extent value for June 2022 into my long-term plot where I calculate the extent anomalies from 1979 up to now.
The average (1979-2022) June extent is now 11.52 M km². June 2022 had an average extent of 10.86 M km², which is 0.76 M km² less than that long-term average.
This month's value was again above the long-term linear trend line. The difference of the actual month from that trend line is +0.40 M km² (calculated from the linear trend line this June should have been at 10.46 M km²).
The slope of the long-term linear trend line became again flatter by two digits (-0.0538 → -0.0536).

from NSIDC Data - Area graphs of some interest

CAA - the hiatus rules again...

Chukchi - in a hurry to melt out

Greenland Sea - strongish melt continues

Which is the best answer to Sep-2012 ASI lost (compared to 1979-2000)?
50% [NSIDC Extent] or
73% [PIOMAS Volume]

Volume is harder to measure than extent, but 3-dimensional space is real, 2D's hide ~50% thickness gone.
-> IPCC/NSIDC trends [based on extent] underestimate the real speed of ASI lost.

The graphs attached show how slow the declime in sea ice area and extent has been this year, especially in the High Arctic.

Where are the "10% daily loss of ice area" seas?
What is going on here?
