But I don't expect any of them to bother answering your email

As Rob has already pointed out, it didn't take long for your theory to be falsified!

For the record, I'm not a climate scientist but I have numerous email exchanges and even telephone conversations with people that are. Sometimes I even get to meet them in person:

Persuading them to "stick their head above the parapet" in public is generally a little trickier. Kevin Anderson needs no such persuading however! Re your final paragraph, get the popcorn ready:

A couple of papers from Pierre Rampal et al.:

neXtSIM: a new Lagrangian sea ice model

and currently under discussion:

Wave-ice interactions in the neXtSIM sea-ice model

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.

Does anyone know where to find HYCOM/CICE forecasts after March 21?

It seems to be up to March 24th now.

It would be an excellent topic if he had real experts instead of three bozos and an expert....

As a wag on Twitter pointed out, the Committee ought to be interrogating seeking the expert advice of another 96 climate scientists.

Smith comes to bury Mann, not to praise him.

At the risk of drifting off topic, may I take this opportunity to point out that whilst we debate how many angels can dance on the head of a pin the cryodenialospheric porky pie production line is cranking up to full speed once again?

Lamar Smith’s Show Trial for Climate Models

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“

An open access paper from the Norwegian young sea ICE (N-ICE2015) expedition:

"Turbulent heat and momentum fluxes in the upper ocean under Arctic sea ice"

Oceanic heat flux is weakly positive in winter over the Nansen Basin during quiescent conditions, increasing by an order of magnitude during storm events. An event of local upwelling and mixing in the winter-time Nansen basin highlights the importance of individual events. Spring-time drift is confined to the Yermak Plateau and its slopes, where vertical mixing is enhanced. Wind events cause an approximate doubling of oceanic heat fluxes compared to calm periods. In June, melting conditions near the ice edge lead to heat fluxes of O(100 W m−2). The combination of wind forcing with shallow Atlantic Water layer and proximity to open waters leads to maximum heat fluxes reaching 367 W m−2, concurrent with rapid melting.

Returning closer to topic, though still a bit offside,* there is a scheduled persecution by Rep. Lamar Smith's Space, Science and Technology Committee (House of Representatives)

Absolutely on topic Susan! What's more Alice and I are on the case even as we speak!!

I'd noticed that too Wipneus!

Meanwhile OSI-SAF tell me:

Concerning the ice type product, there is as you point out a systematic problem that gives multi-year ice in some young ice areas, and we are working on improving that.


Concerning the new AMSR2 product, we will provide a quicklook archive of product images as for SSMIS. This should be available in a couple of weeks.

Although there's nothing on the NPEO web site itself yet, apparently:

No web cams were deployed in 2016, due to funding constraints, however deployments are planned for Spring 2017.

Meanwhile according to yesterday's report on the Barneo Facebook page:

On March 15, a truck with landing equipment set off from Moscow to Murmansk and yesterday it arrived at the destination.

On March 17, another truck and a trailer with loaded platforms and tractors started out from Moscow to Tver (Migalovo airport). The landing party also arrived there. On March 18, the paratroopers with platforms and tractors flew to Murmansk by Il-76. They will be preparing the platforms for airdrop at the Zhalyuzi point.

On March 19, two helicopters of the AeroGeo a/c flew up in Krasnoyarsk and followed the route Krasnoyarsk – Podkamennaya Tunguska – Igarka - Khatanga.

Irina Orlova isn't too keen on the current weather situation:

Today's weather did not allow helicopters to fly from Khatanga.

It seems that the helicopters again tomorrow will not be able to fly out.

Only on 23 March, the weather may change.

For the Russian language experts amongst us, a TV report on the Barneo 2017 preparations is available here:

Vigilius doesn't seem to have taken the hint yet, so with thanks for the heads up, albeit in the wrong place:

The copters type Mi-8T on Sunday morning took off from Krasnoyarsk with course for the north. They will have pitstops in Igarka, Khatanga and on the island of Sredny, Severnaya Zemlya, before they make it all the way to the North Pole, aviation company Aerogeo informs.

The eleven people on board are not only pilots and aircraft technicians, but also experienced polar experts. They will first identify an ice floe suitable for the Barneo-2017, and then help facilitate the delivery on site of people and goods.

Plus some "Shock News!"

It has been speculated about a possible visit to site of President Vladimir Putin. According to SeverPost, the President might go to Barneo ahead of his attendance at the Arctic Forum in Arkhangelsk late this week.

Perhaps the Norwegian powers that be will have second thoughts again this year?

Before we get too deep into melting season, would some of the more seasoned posters mind giving a handful of things they will be keeping an eye on over the next few months to judge how 'good' or 'bad' the melt is going?

5 fingers worth to start with? Not necessarily in order of time or importance!

1. How soon melt ponds and/or open water hang around in the Beaufort Sea this year. Things started very early last year:

2. Ditto the Bering Strait and Chukchi Sea

3. Ditto the Laptev and East Siberian Seas

4. How many (and how deep, warm, wet) spring cyclones spin around the Arctic Ocean

5. How the snow melt progresses across Canada, Alaska and Siberia

Next please!

No wonder I tend to ignore you when you say anything other than pure direct data.  You are asking me to waste my time before giving me a reason to waste it.

Don't you understand economics at all???????

Jim - I've recently spent many happy hours in the company of the deplorable denizens:

Your tactics are identical to theirs.

Please stop being so patronising. Stop the ad homs. State your case, if you have one.

In response to a number of posts discussing the issue of communication with a general audience and whether scientists in general or the authors here should be criticized for their language/format/style; here is an example of the climate denialist reaction; “Natural Variability’s Role in Arctic Sea Ice Decline Strengthens Case for Lukewarming”

Thanks for the heads up. However in response to your posts discussing climate denialist communications perhaps I might take this opportunity to criticize your style? Please do not give the likes of Messrs Michaels and Knappenburger the oxygen of publicity by linking to their hogwash. Instead link to archived versions like this one:

If you have panoply installed you can plot from the .nc file.

I do have Panoply installed, so sure. I've even been beta testing some improvements. Nonetheless it does still seem as though the OSI-SAF web site is somewhat broken in the AMSR2 department.

An article on the self same alleged “correction”:

"Don’t Panic! It’s Just Another Climategate 2 Correction!!"

Last night the Mail Online web site... published an excuse for a “correction” to the egregious inaccuracy published on February 19th 2017 as part of David Rose’s self christened “Climategate 2” campaign in the Mail on Sunday.

One of the numerous problems with the Mail and the GWPF’s version of these recent events is that none of the UK Met Office insiders I have contacted have any idea what the Mail might be blathering on about.

Jim W - This is probably of no interest to you, but I recently had a long discussion at the UK Met Office about their "unified" model that handles both their "weather" and "climate" forecasting. Here you go:,256.msg106820.html#msg106820

Now what exactly is the point that you are endeavouring, but failing, to make? You've presumably heard the old adage attributed to George Box that "all models are wrong, but some of them are useful"?

Here’s a long video of the first ever public event at the Met Office’s new High Performance Computing Complex near Exeter:

The broad theme was the Exeter City Futures project, which aims "to make the region congestion free and energy independent by 2025". I was in attendance, and if you skip to the “Questions” section at the end you can even see me asking the UKMO's Vicky Pope a tricky question! I asked another question later too.

After that I had a long chat with David Underwood, since nobody else seemed terribly interested in what 16 petaFLOPS and counting might ultimately be capable of. Arctic sea ice inevitably entered the conversation. David said he was proud of the UKMO’s “unified” model’s performance in that regard. In ~3 yrs the ocean and atmospheric components of their model are due to become “close coupled”, at which point their sea ice predictions should improve as well.

The proof of that pudding will be in the eating of course!

P.S. My old trick for embedding a YouTube video doesn't seem to work anymore. Does anybody know the secret, if there still is one?
