This morning the Viscount Ridley and Julia Hartley-Brewer have been prattling on about the "hypocrisy" of XR. At ~50:00 minutes Matt exhorted Julia's loyal viewers to "stand up to the bullies", so I did:
Dear Jim Quixote,

Being bored with windmills & the WUWT, you decided to tilt your lance against "Twin-set & Pearls" Julia and "I Broke the Bank" Ridley? Ripley being an advisor to one of Voldemort's spin doctors (the GWPF), that would suggest the Fragrant Julia is of like mind.

Stick a stake through their hearts, and just like Dracula, they will be back in yet another "Hammer Horror" movie before the blood on the stake is dry.

Ridley was educated at Eton. Eton alumni - Cameron, Johnson, Rees-Mogg, Ridley. Is Eton an asset to the UK?
Ridley chaired the UK bank Northern Rock until 2007, during which time the bank experienced the country's first bank run in 140 years. Ridley resigned, and the UK Government bailed out the bank, leading to the nationalization of Northern Rock. Ridley was responsible, according to parliament's Treasury select committee, for a “high-risk, reckless business strategy” which the bank was able to pursue as the result of a “substantial failure of regulation” by the state.

The family's got form ..

Uncle Nick - yes, educated(?) at Eton
"More importantly, he was the Cabinet Minister responsible for the introduction of the 'Poll tax' (formally known as the Community Charge), a policy that brought a standing ovation at the Conservative Party conference at which it was announced, and riots across the country when it was implemented.

The grim news for US shale drillers continues.

U.S. oil production growth has slammed on the breaks, as low prices and the loss of access to capital markets has forced a slowdown in drilling.

Third quarter earnings reports will soon start to trickle in. Three months ago, the shale industry saw improvement in some of the headline cash flow figures, but the second quarter results also revealed some deeper concerns about drilling operations and raised questions about the longevity of an unprofitable oil boom.

The problem for the shale industry is that, if anything, the outlook has only become gloomier since. Oil prices have languished and investors have grown more skeptical.

The cutbacks have translated into slower output and have led to questions about the “end” of the shale boom.

“A marked slowdown in the US shale patch since the start of the year has led us to lower our expectations slightly for US crude production for 2019 and 2020,” the International Energy Agency (IEA) said in its October Oil Market Report. “Despite many new pipeline projects coming on-line during 2H19, operators continue to lay off rigs and instead prioritise investor returns.”

The Paris-based energy agency noted that U.S. oil production only grew by 140,000 between January and July, a notably modest increase, especially when compared to the 740,000 bpd U.S. drillers added in the same period last year.

The IEA said that cutbacks in spending were a big part of the slowdown. “Pure-play shale producers and independents had already flagged a 6% decline in upstream spending this year in their initial 2019 guidance,” the agency said. “Operators shed another 29 rigs during September so that by end-month, there were 172 fewer active rigs than at end-2018. The frac spread count has declined 23% since March, to a 2.5-year low.”

Here's a link to an interesting article about how renewables are being built to replace a coal power plant powering a large still mill in Colorado.

As I watched recently, the great arc furnace at one of the nation’s most storied steel mills was sucking in more electrical power than any other machine in Colorado, produced in part at a plant a few miles away that burns Wyoming coal by the ton.

But the electrical supply for the mill is changing.

A huge solar farm, one of the largest in the country, is to be built here on the grounds of the Evraz Rocky Mountain Steel mill. In addition to producing power for the giant mill, the farm, Bighorn Solar, will supply homes and businesses across Colorado. So far as I can tell, Evraz Rocky Mountain will be the first steel mill in the world that can claim to be powered largely by solar energy.

There is a caveat: The mill operates 24 hours a day and solar panels do not, of course. Over the course of a year the solar farm is expected to produce electricity roughly equal to 95 percent of the mill’s annual demand. On sunny days, excess power will be sold to the Colorado grid, but at night the mill will draw power from the grid, which still includes a good bit of fossil energy.

But that is getting fixed, too. Xcel Energy, the utility that supplies the Pueblo mill with electricity, has made one of the most ambitious commitments in the country to clean up its system. Luckily, about the time solar panels are going dark, strong winds whip up across the plains of eastern Colorado, where wind turbines will turn it into power.

Alice Jackson, who runs the Colorado division of Xcel, told me that at certain hours during the night, wind farms can supply as much as 70 percent of the power on the state grid, and that is likely to be true more and more often as the company signs contracts with new wind farms.

Why would a steel mill install a solar power plant next door? The company cares about going green, certainly, but this is also about money.

We do not know the exact price the company will pay for its solar power — that is a secret under Colorado law — but we do know that the cost of large-scale solar farms has plummeted. To improve its finances, Evraz seems to be locking in low-cost power for the long term.

Indeed. There is refreeze in Kane Basin but Lincoln seems stubborn.

Why can't we the funding public get access to terraSAR imagery?
It is being used quite a bit now at Neumayer Station in Antarctica. Provides great imagery ... though we are looking for ultra-high resolution at one spot in the Arctic Ocean; orbital coverage may have to be requested.

I found that image on the blog of R Moore, who is part of the @MOSAiCArctic field school. It did not enlarge on a click and but does  not represent the full quality available. It is 1024 x 795 and said copyrighted, though under non-commercial Fair Use Doctrine, it can be freely distributed especially if trivial changes like 180º inversion are made (new art).

The blog posting predated selection of the floe. She did not know/say that this was The Floe, that is my interpretation. As usual, no identification numbers were provided with the image so we wouldn't know what to ask for. It is better to embed ID numbers in the image or include them in the file name so they can't get separated (as in EXIF metadata).

Exif direct-to-url yielded:

Pixels Per Unit X: 2835
Pixels Per Unit Y: 2835
Pixel Units: Meters
Modify Date: 2019:10:15 01

Here that was ominously satImage_smallsize.png which could mean cropped or dumbed down in resolution or both. Sounds like it was resized down from an original 2835 x 2835 but by whom? The floe is about 100 pixels high as downloaded; in real life it is ~3500 m in this dimension. The exif meters/pxl then makes no sense.

I did not get anywhere walking back the directory to a folder that might contain a full size version, just 403's forbidden. Not sure why it is hosted at CIRES Colorado when Moore is a grad student in applied math at Utah, on the AF for six weeks. At any rate, I wrote away for the original file.


Interesting that the leads are largely east/west. Those leads look quite imposing.
That is a typical shearing pattern seen in brittle material failures. It extends some 20 multiples of the floe's width in the png posted above which is ~50 km. There is some hint that it has forked around the (thicker) selected floe. Today was a two-fer on S1B: the PS floe was caught at two times an hour and 38 minutes apart (below, green dot is Polarstern).

We need to map the opening and closing of leads over the last month, easy given a co-registered archive. Both Gimp and ImageJ are loaded with edge detectors, which is run on your image below.

Leads can open and close up overnight to the point of unrecognizability. Pressure ridges ... not sure they can be seen. Might be lighter lineations due to roughness on the scale of Sentinel-1AB which operate at 5.404 gigahertz, meaning surface roughness at the order of the 5.5 cm wavelength.

Incredibly close call with those big leads opening but they could have relieved a lot of regional ice stress. They also could have sent a lot of difficult-to-replace and mission-critical equipment down to a watery grave. (As happened on two occasions to the hovercraft party.) Or split the legs on the Met tower if 5 m to .the left. It is interesting how much ice noise they report even frozen on the floe.

Update: looks like those big leads arose as single CW torquing failure during an "attempted rotation". The wind shifted. I'll add the whole time series in a bit ... taking screenshots off saves trying to locate the Polarstern on a huge downloads.

I agree that the XR movement is getting out of control...

I could not disagree more strongly. Young people don't want to live in a world where hundreds of millions die (perhaps billions) due to climate change. Given the stark fate they are facing, I'm thinking they need to up the pressure.

look back a year and the temp anomaly outlook was very similar . However 10 days later the reality was a much colder Arctic . The refreeze had accelerated to @ 170k sqkm per day .. a rate that was maintained for @ 3 weeks and earlier long-range forecasts were proved meaningless . b.c.

Climate change is already harming Great Lakes region, Debbie Stabenow warns
A "climate crisis" is affecting Michigan’s economy, agriculture, public health and the Great Lakes, according to a new report.
This hits me where I live.

I really appreciate all your comments and links and, as you note, "this hits me where I live," too. I'm in eastern Lorain County. We seem to have similar perspectives and perhaps we could "chat." Reach me via golfwalker at hotmail dot com at your discretion.
