NSIDC  ARCTIC SEA ICE AREA (5-day trailing average):  11,891,960 KM2 as at 03-May-2023

- Area loss on this day 38k, 15 k less than the average loss on this day (of the last 10 years) of 53k,
- Area loss from maximum on this date is 1,041 k, which is 394 k, 27.5% less than the 10 year average of 1,436 k.

- Area is at position #16 in the satellite record (#1=lowest),  of which 1 year(s) are before the year 2000

- Area is  94 k MORE than 2022,
- Area is  533 k MORE than 2020,
- Area is  818 k MORE than 2016
- Area is  157 k LESS than 2012
- Area is  209 k MORE than the 2010's Average
_____________________________________________
On average 14.4% of Area losses  from maximum to minimum done, and 130 days to minimum

Projections.

Average remaining Area loss (of the last 10 years) would produce a minimum in Sept 2023 of 3.39 million km2, 1.14 million km2 above the Sept 2012 record low maximum of 2.25 million km2, and 14th lowest in the 45 year satellite record.

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.

Sea ice extent loss stalls & even increases in the last 2 days while sea ice area losses continue even if a bit less than average. Winds & sea ice drift?

NSIDC  ARCTIC SEA ICE AREA (5-day trailing average):

Overall sea ice extent and area losses this melting season are proceeding slowly, but within that overall picture are quite high deviations, as noted in the following..

Canadian Archipelago sea ice area has dropped like a stone in the last 5 days, from 38th lowest (8th highest)  to lowest in the 45 year satellite record on this day.

Baffin Bay sea ice area loss has started to accelerate, but only modestly.

Fram export into the Greenland Sea and sea ice movement into the Barents Sea seems to have reduced or stopped, with sea ice area gains having stalled in both seas.

However, there is little sign of a major acceleration of melt on the horizon, and with area loss to date 24% below the average of the last 10 years, as every day passes the probability of a major event this year reduces (but does not disappear).

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.

NSIDC  ARCTIC SEA ICE AREA (5-day trailing average):  11,393,936 KM2 as at 14-May-2023

- Area loss on this day 81k, 18 k more than the average loss on this day (of the last 10 years) of 63k,
- Area loss from maximum on this date is 1,539 k, which is 426 k, 21.7% less than the 10 year average of 1,966 k.

- Area is at position #15 in the satellite record (#1=lowest),

- Area is  105 k MORE than 2022,
- Area is  486 k MORE than 2020,
- Area is  964 k MORE than 2016
- Area is  53 k LESS than 2012
- Area is  281 k MORE than the 2010's Average
_____________________________________________
On average 19.8% of Area losses  from maximum to minimum done, and 119 days to minimum

Projections.

Average remaining Area loss (of the last 10 years) would produce a minimum in Sept 2023 of 3.42 million km2, 1.18 million km2 above the Sept 2012 record low maximum of 2.25 million km2, and 14th lowest in the 45 year satellite record.

NSIDC  ARCTIC SEA ICE AREA (5-day trailing average) fell by 81k km2 on this day.

Meanwhile the one day loss was 203k km2 (from Nico Sun @ https://cryospherecomputing.com/).

From the anomaly map and the NSIDC images attached it seems that sea ice area loss is mostly happening in the SW third of Hudson Bay (where there have been ridiculously high record May temperatures) and the American side of the Chukchi.

Once again - a blip or to be sustained?

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.
