It's the last place you want thicker than normal ice in the Arctic if you want to see the ice retain volume during the summer melt season.
The melt season is half way over and this season has yet to gain ground in CAB volume vs. 2012 or 2019.
No one is arguing that ice is lost via export to the Atlantic side, but we can try to use math to quantify it.
Wipneus provides a chart in the PIOMAS thread which aims to measure the volume of CAB ice being lost to the Fram Strait which we can all agree is the primary channel of loss.
If the chart shows us losing ~ 100 km3 in June, what is the impact on the minimum?
First, we have to give a haircut to the volume by ~ 50%, because if the ice wasn't exported, then it would have melted in place like the rest of the CAB. So that leaves us with 50 km3 as the expected volume of that ice at the minimum if it weren't exported.
Then we have to apply another haircut because the ice is thicker in the CABlantic this year. If the ice is twice as thick, then 25km3 is the additional amount being lost due to their being thicker ice in that region.
Take the extra 25km3 in minimum impact being lost through the Fram each month and add some lesser amount for the Barents export. How does that stack up to the deficit that 2020 needs to overcome in order to set a record? A: Not very good.
Explain why the additional export volume loss in 2020 will be quantitatively material yet we haven't seen 2020 move up yet on the leading years halfway through the season.
