I belive that the mole eats slugs because things are much better this year. I hope it will continue that way.

Arctic sea ice / Re: The 2019 melting season

I'm trying to reconcile some understanding here.

The high pressure seems to be a big concern because it's related to a lot of sunshine over the ice at a time when the sun is out nearly all day.

We also know that ice has generally high albedo which means it reflects sunlight without being absorbed.

I'm assuming that concern would be in the areas w/ much less than perfect albedo due to open water, melt pools and spaces between fractured ice.

Is that right?

Looking at the weather forecast, it looks like the predominant area of warmth (above freezing) are on the Russian side seas. The CAB area has a small positive anomaly, but average doesn't look much above freezing, if at all.

With dramatic loss of old thick sea ice since 2010, I would expect that PIOMAS Sept. minimum would show stronger downward trend for 2010-2019, but while the long term trend is obvious, the last 10 years have been fairly flat.  Why doesn't loss of old thick ice show up more in PIOMAS Sept. minimum volume?

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

May 26th, 2019:
     11,063,862 km2, a drop of -17,846 km2.
     2019 is 2nd lowest on record.
     (2012 highlighted).

What is most striking to me in looking at these images is not the comparison between 5/26/2019 and 5/26/2012. It is between 5/26/2019 and the final condition of the ice at the end of the 2012 melt season. Since the end of the 2012 melt season, the thickest ice has continued to disappear. We are only one severe melt season away from a BOE.

This post continues exploring how 2012 compares to our current melt season. Hopefully this will spur discussion or guidance on creating something more helpful.

I realize that insolation is now a much more important factor than DMI 80N-90N air temps. i'd rather substitute the DMI temps with an insolation graph for the Arctic, but i do not even know if such data exist? Also, a 65N to 90N 925mb temp breakdown, like Neven does, would better capture the heat that affects active melt regions south of 80N.

I can't help but notice an apparent huge discrepancy between what PIOMAS reports as average arctic sea ice thickness and what Navy HYCOM+CICE shows. It seems that these two products are on opposite ends of the spectrum. Perhaps reality is somewhere in the middle?

Edit: i now realize these two products are a bit of an apples to oranges comparison with 2012 average PIOMAS thickness being lower because there is more extent to average the thickness across and some of that added extent is thinner ice.

Is the issue about card payment the IT and network that is required ? Or is it the problem that it allows consumption at any time ? I don't get the point.
Mornin', no it's not technical issues, they are looking at offering both swish and cards but they need more customers before they can take the next step. Ekobanken is built by their customers and they don't have a large investor behind them. Large investors often lack the required ethics.
