Is there some formula for translating the thickness of a single chunk of ASI ice into a relative or absolute melt resistance value?

Not that I'm aware of. Melting is a much messier process than freezing.

A "Great Arctic Cyclone" in August seems to have a significant effect on Arctic sea ice melt for example!

Last year over on the Nares Strait thread, we were saying that the ice north of Greenland in the Lincoln Sea must be thin as it kept fragmenting and there was no arch in the strait. Yet the 2019 chart above appears to show thicker ice above Greenland than this year.

And what happened to the "thicker ice above Greenland" of which you speak after mid January 2019? According to the theory which is mine:

Over the winter of 2018/19 ASCAT revealed that there was a relentless movement of multi-year ice towards both the North Atlantic and the Beaufort Sea. Perhaps a significant amount of the multi-year ice that survived the winter of 2018/19 has now simply melted away in warm water, to be replaced by much less robust first year ice in the area between the North Pole and the Siberian coast?

I'll allow that some melted out in Baffin Bay as well.

However, the sea ice extent this year is greater than 8 of the past 10 years.

So sea ice thickness is irrelevant to your potential prognostications? Here's another sea ice motion video for you:

The extra volume this year is in the Barents (and the Kara)

I've done my due diligence this morning (UTC), and there's still a total absence of any ice >= 4m thick to be seen on the most recent CS2/SMOS reanalysis. Chapter and verse over at:

including this (hopefully?) explanatory video:

Not unexpectedly that meant that ice in the northern Barents Sea was slow to melt out in the summer of 2019, whilst after a fast start the melt in the Beaufort Sea suffered a “brief hiatus” in June before ultimately melting out almost completely.

Or am I missing/misinterpreting something?

Well, since I grabbed the 2019 data earlier today rather than a year ago that map is based on a "reanalysis", whereas the 2020 one is based on "operational" data. That may have something to do with it?

I'll have to do a lot more digging to confirm that, or otherwise. However that will have to wait for another day, since it's now well past my normal bedtime (UTC)!

A new PIG learned journal article, available behind the Nature paywall via Jonathan Bamber's Twitter feed:

We use high-resolution satellite observations of elevation change since 2010 to show that thinning rates are now highest along the slow-flow margins of the glacier and that the present-day amplitude and pattern of elevation change is inconsistent with fast grounding-line migration and the associated rapid increase in mass loss over the next few decades.

According to the Grauniad this evening (UTC):

Coronavirus: 100,000 may already be infected, experts warn

About 100,000 people could be infected with the new coronavirus around the world, experts have warned, as the UK government faced calls to reassure people that the NHS is ready to deal with any British cases within days.

Prof Neil Ferguson, a public health expert at Imperial College, said his “best guess” was that there were 100,000 affected by the virus even though there are only 2,000 confirmed cases so far, mostly in the city of Wuhan in China where the virus first appeared.

“Sooner or later we will get a case,” he said. “There are very large numbers of Chinese tourists across Europe right now. Unless the Chinese manage to control this, and I’m sceptical about whether that is possible, we will get cases here.”

Although no one has yet tested positive for coronavirus in the UK, Labour called on the government to reassure the public that the NHS could cope with an outbreak when it is already struggling with the winter flu season.

Jonathan Ashworth, the shadow health secretary, said: “The NHS is currently under immense strain this winter with staff already working flat out and hospitals overcrowded. We need urgent reassurance from ministers they have a plan to ensure we have capacity in place to deal with coronavirus should we need to.”

Priti Patel, the home secretary, insisted on Sunday that the government was taking “all precautions”, despite criticism it had been slow off the mark to find and give information to the thousands of people in Britain who had flown back from Wuhan in recent weeks.

Prof Martin Dove, a British academic, said no one from the UK government had tried to contact him regarding the coronavirus outbreak despite recently returning home from working in Wuhan.

Growth is faster and the temperature gradient quite different for a while.

The gradient change (especially when the air is cold!) reveals the boundary between snow and ice.

The overall motion of the icepack over the last three weeks is better described as a 'Siberian Slam' against the CAA than TransPolar Drift. Note the boundary between FYI and MYI remains quite distinct and easy to track.

An interesting new paper concerning the Arctic surface energy balance from the Department of Atmospheric Sciences at the University of Utah:

Midwinter Arctic leads form and dissipate low clouds

Also here's an introductory overview:

In the wintertime Arctic, cracks in the ice called "leads" expose the warm ocean directly to the cold air, with some leads only a few meters wide and some kilometers wide. They play a critical role in the Arctic surface energy balance. If we want to know how much the ice is going to grow in winter, we need to understand the impacts of leads.

The extreme contrast in temperature between the warm ocean and the cold air creates a flow of heat and moisture from the ocean to the atmosphere. This flow provides a lead with its own weather system which creates low-level clouds. The prevailing view has been that more leads are associated with more low-level clouds during winter. But University of Utah atmospheric scientists noticed something strange in their study of these leads: when lead occurrence was greater, there were fewer, not more clouds.

Christopher Booker is dead. Long live Sarah Knapton?

A Climate Feedback takedown of an article by The Daily Telegraph's alleged "Science Editor", Sarah Knapton:

This article in The Telegraph attempts to discuss the science of observed global warming and the factors responsible. However, mixed in with some accurate factual statements are claims that give readers the impression that the answers are unknown, and climate science is “up for debate”.

So not quite there yet.

Matt Ridley was on Julia Hartley-Brewer's "chat show" earlier. Apart from accusing Extinction Rebellion of "hypocrisy" Matt was rather economical with the truth about Arctic temperatures and sea ice. At the end of the video he exhorted Julia's loyal viewers to "stand up to the bullies". I think he was referring to XR, but I took him at his word and stood up to the purveyors of porkie pies at Watts Up With That in no uncertain terms:

guessed possible as far as @Jim is concerned.

You are very kind Philopek.

As far as I can ascertain the only possible motivation for Mr. Watts actions is to prevent his loyal readership from being exposed to the data (perhaps "facts" is too strong a word?) emanating from the Arctic.

The CryoSat-2 image is from the laser thingy?

IceSat-2 is "the laser thingy". CryoSat-2 is the "interferometric radar range-finder thingy":

It's a "measurement" of sorts, but still has to make assumptions about snow thickness to turn freeboard measurements into sea ice thickness numbers.
