PIOMAS 2023 ASI Volume September Average: June poll
« on: June 01, 2023, 10:27:07 PM »
Values from the PIOMAS Monthly Ice Volume Data:
http://psc.apl.uw.edu/research/projects/arctic-sea-ice-volume-anomaly/data/

I add a comparison against the 1979-2000 September Average. It is worrying to see that there are several years where we have less than half the ice, by volume.

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.

For volume, I went a little lower than the previous 2 years because of all the Fram export we had this year. So I picked between 4.25 and 4.75.

WTF happened?

The possible outcomes are really all over the place in this one. I went for a conservative 4.50-5.00.

3.75-4.25 it is.

Before I came here I was confused about this subject. Having listened to your lecture I am still confused. But on a higher level.

I think it will end in the 4.25-4.75 kkm³ bin.

This looks the most likely to me too. Not nailed on yet, but in the chasing pack rather than seriously challenging the lowest years.

I vote on this bin too.

P.S. Around 16 hours to vote or change your vote.

The final Sep avg was 4787 km3, as calculated by Gero. 7 out of 30 voters got the right bins. Most expected a lower result, but this season was a late bloomer.
