The final drift map from Barneo 2017, including comparison with previous years:

Can you explain the attached graph? Is that air temperature, per hour, on the 12th of April?
New work by an international team led by Igor Polyakov of the University of Alaska Fairbanks provides strong evidence that Atlantic layer heat is now playing a prominent role in reducing winter ice formation in the Eurasian Basin, which is manifested as more summer ice loss. According to their analysis, the ice loss due to the influence of Atlantic layer heat is comparable in magnitude to the top down forcing by the atmosphere.
A closer look shows the openings in the Beaufort are freezing over fairly quickly, not really unexpected this time of year, in my humble opinion.
Two technical flights of the Antonov-74 from Longyearbyen have landed at Barneo airdrome. It is officially confirmed that the ice runway meets all the standards and Barneo starts 2017 season!
All the team is on the ice constructing the camp. Also two groups of skiers have already arrived at Barneo with the second technical flight. They are going to pass the distance of two degrees to the Pole.
Tomorrow Barneo airdrome will work according to the schedule. Today there is a delay - the skiers who were supposed to fly to Barneo this morning will be there tonight, after the 3rd technical flight.
Many thanks for all your interesting/burning/critical/constructive comments and questions on our paper and my thoughts.
It could be a meter thick!
Arctic Sea Ice Currently Taking a Hit From All Sides
Today is All Fools’ Day, but this is no joke.
What on Earth are Rep. Higgins and ex Prof. Curry on about with all this “RICO” business?
"Would you be able to at some future date provide to this committee evidence of your lack of association with the organisation Union of Concerned Scientists and lack of your association with the organisation called Climate Accountability Institute? Can you provide that documentation to this committee Sir?"
I am aware I am kind of resurrecting this thread
A crowd-funded, collaboratively developed, Open Source climate model is always a Good Idea (tm) imho.
The significant caveat here, according to my limited expertise in the subject, is that parallel climate simulation algorithms require high bandwidth and low latency interconnects between computing nodes. Hence most are run in batch mode on supercomputers, and do not lend themselves to a distributed environment.
Note that some (many?) climate models are Open Source and their source code is freely available for academic purposes. But honestly, downloading this kind of source code which would take months to run on a desktop PC doesn't seem very practical to me.
Steig had a very nasty experience many years ago when Iago McIntyre came after him
Yet now Eric Steig decided to take his opinion about me and the process of expressing scientific criticism on his paper in this fine blog public in a rather unprofessional rant of 9 twitter posts
Roberts has spent the last seven or eight years working as the project manager of the Galileo Movement — a climate science denial group launched in 2011.
Tony Heller is a proven purveyor of porky pies covered in lashings of cherry sauce:
Jim, I wouldn't even waste your breath with Malcom Roberts.
Jim, what's going on in the Arctic data scrubbing story?
The Russian president is touring Franz Josef Land, a desolate archipelago in the Arctic Ocean, to inspect the environmental cleanup effort conducted there. A day later he is to take part in an international conference on Arctic development hosted by Russia.
Vladimir Putin landed on Wednesday on Alexandra Land, the westernmost island of the archipelago, lying some 1,000km north of mainland Russia near the Barents Sea. He is touring the desolate part of the country to inspect the progress in cleaning up waste left behind by Soviet expeditions and military deployments in the past.
We should no longer be duped into playing along with this strategy.
Despite sending many skilled science communicators to testify at the hearings over the years and even when scoring tactical victories, the strategic effect of participating at these hearings has been to sustain the perception of false equivalence, a perception only exaggerated by the majority’s ability to select a grossly disproportionate number of witnesses far removed from mainstream science (it’s not coincidence that Judith Curry, professor emeritus, Georgia Institute of Technology, and John Christy, professor of atmospheric sciences, University of Alabama at Huntsville, are called upon so often by the Republicans).
A better response would be to simply boycott future hearings of this kind and to call out these hearings for what they are: a tactic to distract the public from a serious policy debate over how to manage both the short- and long-term risks of climate change.
...and am I correct in saying that in Beaufort, at least, the (few) on-the-ground thickness measurements (from the new 2017 IMBs) indicate that PIOMAS may itself be somewhat on the high side?
As usual your latest post on your blog is a must-read, and I just read it with particular interest, because it is in many ways related to this thread.
What is one to do, then, when Anthony Watts publishes these scurrilous allegations about one's character by the pseudonymous "Sunsettommy" under an article by David Middleton on a topic under much discussion here?
Barneo 2017 being established.
Curry, Pielke, Christy -- all three superstars of climate denial will appear before the US House Science Committee next week!

The amount of attenuation that waves in ice experience is the main factor in determining the amount of momentum transferred to the ice. However, definitive confirmation of any particular physical models for this is still lacking.
It would be an excellent topic if he had real experts instead of three bozos and an expert....
All in all there’s several “alternative facts” in just the headline and opening paragraph of the GWPF’s press release, which doesn’t augur well for the contents of the report itself.
We feel sure that Lamar Smith and the House Committee on Science, Space and Technology will nonetheless be pleased to see this report become public shortly before their planned hearing on March 29th entitled “Climate Science: Assumptions, Policy Implications, and the Scientific Method“:
We also feel sure they were pleased to view the contents of another recent “white paper” published under the GWPF banner. The author was ex Professor Judith Curry, and the title was “Climate Models for the Layman“
