Sea level to accelerate more quickly prompts sea level rise denial at WUWT

Sou | 4:38 AM Go to the first of 18 comments. Add a comment
There's a new paper out that has been picked up by Anthony Watts. Of course he doesn't like it because it's about one of his pet peeves - rising seas. There are few things he is more afraid of, judging by the frantic attempts he's made over the years to deny that seas will rise as the ice melts.

I don't have time to do the paper justice, so I'll point you to the paper and an article by John Abraham at the Guardian. The paper is by John Fasullo, R. S. Nerem & B. Hamlington and is in Nature's open access journal Scientific Reports. The gist of it is that the volcano, Pinatubo, suppressed sea level rise, and it could be about to jump back up again in the next ten years.

The thing I noticed at WUWT is that Anthony Watts will go to great efforts to hide the data. He put up a wonky chart that Willis Eschenbach drew a few years ago. His chart stops some time in 2010 - right before that big dip in sea level when all the water was shifted from the oceans to Australia, South America and Asia.

ICYMI - there's no stopping the rise in surface temperature!

Sou | 8:40 PM Go to the first of 24 comments. Add a comment
In case you missed it (ICYMI), a couple of new papers have been published recently, demonstrating that there has not been any "pause" or "hiatus" in surface temperature in recent years. Yes, the rate of increase wasn't as high as it has been in some other periods. However these papers demonstrate that there was nothing different from what can be expected from a warming trend with interannual variability imposed on it.


Change points of global temperature: Cahill, Rahmstorf and Parnell


If you're a fan of realclimate.org (the benchmark of world best practice in climate blogs), then you might remember the change point analysis written up there last December, by Stefan Rahmstorf. The article was called "Recent global warming trends: significant or paused or what?" This new work looks to be on the same topic written as a peer-reviewed paper in IOP Science: "Change points of global temperature". It's open access so you can read it at your leisure.

Bob Tisdale's latest conspiracy theory about ocean heat

Sou | 3:30 AM Go to the first of 9 comments. Add a comment
Today Bob Tisdale has found a new conspiracy theory that he's promoting (archived here). It's much the same as all the others. From his ergonomic computer chair in his basement (is he that advanced?) Bob decided that another group of scientists must be fudging the data. Problem is, Bob doesn't understand the data or how to use it, let alone how the scientists analysed it.

A warning that this article is long. I enjoyed writing and researching it. The paper this article is based on is a great example of the sort of effort and thinking required to scope out and quantify the changes we're bringing about. Which is of critical importance IMO.


Progress in determining changes in ocean heat content


The paper Bob doesn't like this time is by Dr. Lijing Cheng  from the International Center for Climate and Environment Sciences in China, and co-authors Jiang Zhu and John Abraham. They have been looking to improve the record of heat content of the top 700 m of the ocean. The paper is called: "Global upper ocean heat content estimation: recent progress and the remaining challenges". As the title suggests, the paper describes recent progress in this regard, and the challenges that remain.

Update: Click here for the outcome



Everyone's talking about it and I don't want any of HotWhopper-ites to miss out on the fun.

You can read all about it here.  And if the party at Greg's place is too crowded you can join the party at the burrow.

I'll keep my eye out for updates and ask all of you to do the same.



It's all related to this.

Holey Moley Arctic

Sou | 3:57 PM Go to the first of 8 comments. Add a comment

Anthony Watts has another post up at WUWT protesting the declining ice in the Arctic by pretending that it's not unusual.  At least this time he left off the photo that was proven to be not of a submarine at the north pole in 1959.  He's jumped ahead nearly 30 years to 1987.

Holey Moley - From Neven:
Watts seems to have a renewed interest in the Arctic, now that we won't be seeing back-to-back records after last year's insane record smashing melting season. I prefer to ignore his sh*t, but his timing was so impeccable this time that I had to react: Hole.
If you've not been keeping up with Neven's excellent Arctic Sea Ice blog (eg on the grounds that this year may not be another record low), you're missing out.  As John Abraham wrote in the Guardian recently (my bold italics):
Neven, like many other armchair scientists has little formal training. But, he makes up for that with a doggedness that would impress anyone. While he describes his blog as basically weather reports, many publishing researchers turn to him for a comprehensive view of current conditions. Do you want to know what the short term ice conditions will likely be? Ask Neven. Interested in learning about impacts of current conditions on the atmosphere? Ask Neven.
Not only is he a great resource, but the commenters provide insightful thoughts as well. And very often, they are not in agreement with each other. It is refreshing to see people engage in polite yet candid discussions of various views of our Arctic.

Neven is fact-full and normally doesn't say much about disinformation from deniers, preferring to explore what is happening to Arctic sea ice.  But he is not unaware of Anthony Watts and others like him who are in the climate science denial business.

Go read his latest article.  While Anthony Watts is posting unconvincing BS with his "the holes now are no different", it looks as if there are real holes in the ice opening up near the north pole.  The holes will be considerably bigger (kilometers wide) than the little cracks shown in Anthony's August 1987 photo, which look as if they aren't much more than about 100 m or so in diameter from the photo. (The length of the longest sub in the picture, USS Billfish is 95.02 metres).

Here is Anthony's "evidence":
Credit: Commander Submarine Force, U.S. Pacific Fleet
The above photo, taken in 1987, is described as:
USS BILLFISH (SSN 676), CDR F. Terry Jones (Jeffrey Gossett), USS SEA DEVIL (SSN 664), CDR Dennis A. Napior (Douglas Shaefer), and HMS SUPERB (S 109), CDR James Collins (Don Stephens), conducted the first multi-national 3-ship rendezvous at the North Pole

North Pole not so trivial trivia


Incidentally, 1987 was the year that Australian Dick Smith became the first person to fly a helicopter over the North Pole!

And some more interesting bits of non-trivial trivia that I came across while researching this.  Who was the first person to reach the North Pole and when?  More on that here.  And how easy was it to get to the North Pole back in 1988?  What about trying on a sailboard?  Does anyone know if Stéphane Peyron made it? He did cross the Atlantic on a wind-surfer. Back in 1988 (glasnost era) a joint Canadian-Russian group tried crossing the Arctic on skiis to promote international cooperation, and they made it!

This article gives a thumbnail sketch of the Arctic with some historical context.


From 1958 to to 1987 to 2010

As for Anthony's wrong then corrected then repeated but uncorrected claim relating to a photo he wrongly attributes to a submarine surfacing at the North Pole in 1959.  While the Skate did surface at the North Pole in March 1959, Anthony's photo was not of that event.  Nor does it signal that ice cover today is anything like what it was back then.

1958 - First sub go under the North Pole (reportedly)

And here's an article about the first ever submarine to travel under the North Pole - or perhaps to admit to it.  The Nautilus.  In August 1958. But it didn't surface there.  Here is a paragraph:
The submarine traveled at a depth of about 500 feet, and the ice cap above varied in thickness from 10 to 50 feet, with the midnight sun of the Arctic shining in varying degrees through the blue ice. At 11:15 p.m. EDT on August 3, 1958, Commander Anderson announced to his crew: "For the world, our country, and the Navy--the North Pole." The Nautilus passed under the geographic North Pole without pausing. The submarine next surfaced in the Greenland Sea between Spitzbergen and Greenland on August 5. Two days later, it ended its historic journey at Iceland. For the command during the historic journey, President Dwight D. Eisenhower decorated Anderson with the Legion of Merit.

Here is the New York Times reporting the same journey.  Some relevant extracts:
He recounted briefly how the Nautilus had cruised submerged on a northerly course past the Aleutian Islands and through the Bering Strait between Alaska and Siberia toward the brittle fringe of the ice pack and then beneath it.
Above the Nautilus the covering icecap was plainly visible over the vessel's closed-circuit television, the sixth months period of Arctic daylight making visibility no problem. Now and then great holes appeared in the icecap but the Nautilus sped on....
...Commander Anderson indicated a distinct lack of curiosity about the precise make up an penetration of the icecap below the surface of the sea. It ranged in thickness from ten to fifteen feet and loses about three feet of its winter depth in summer. But pressures caused by wind and tide, sent it to a depth of fifty feet in unchartered places and these were well above the submarine, he explained....
...A humorous note crept into the recitation as Commander Anderson gave the first public definition of what he called "longitudinal roulette," a passtime not to be indulged in while traversing the arctic sea for the first time in a submarine.
"A trip across the North Pole, where there is no opportunity to observe anything outside of the ship, no opportunity to observe stars or do any type of electronic navigation, presents a very formidable problem- or what has been up to now a very formidable problem," the skipper explained.
"For example, it would be possible for a ship equipped with conventional navigation equipment to become so confused at the North Pole that they might actually work themselves around in a slow circle, thinking that they were going in a straight line, and end up coming into perhaps the ice-locked coast off Greenland, or even more disappointing, back where they came from."

I doubt Commander Anderson would have imagined back then that not much more than sixty years later, the Arctic would not only be able to be traversed by submarines, there would be commercial shipping routes opening up - without ice-breakers or with only occasional help from them.

From the Wall Street Journal, ships transporting oil and gas through the Arctic, which is quite a worry, given the huge risks posed by commercial shipping in the Arctic, from Seatrade Global.

On Plain Denial: Watts Dismisses His Own Evidence That is Counter to His Viewpoint

MobyT | 5:20 PM Go to the first of 2 comments. Add a comment
Blogger Anthony Watts is boasting that his denial shenanigans finally got some attention from normal people who aim to educate others about climate change. For some unknown reason he was interviewed by James Stafford for OilPrice.com.  There have been a number of articles commenting about that interview, so I'll just post some links rather than repeat the points:


Plain Denial: How Anthony Watts Smears Himself


What I'm writing about is how Anthony subsequently proves that what he regards as a 'smear' is spot on.

Anthony is particularly thrilled because not only did he (briefly) feature on RealityDrops for spreading disinformation, he managed to catch the attention of Professor John Abraham, who with  Professor Scott Mandia and Dr Ray Weymann set up the Climate Science Rapid Response Team.

In James Stafford's follow up interview for OilPrice.com, John Abraham mentioned Watts more than once - he mentioned him many times.

Anthony was incensed as well as thrilled to be noticed, and seems to think he is posting a rebuttal to Abraham's take-down.  He quotes this passage from the Abraham interview (my bold):
The fact is that Mr. Watts is not a pragmatic sceptic. Real scientists are sceptical by nature. We don’t believe what our colleagues tell us until we verify it for ourselves. Scientists honestly develop views of how the world works and they test those views by experimentation. As a result of approximately 150 years of climate science, the vast majority of scientists are convinced that humans are a major cause of climate change. Mr. Watts, on the other hand, dismisses evidence that is counter to his viewpoint. That is not scepticism–that is plain denial.
Anthony says the above statement is a smear.  Then proceeds to do exactly that - dismissing evidence that is counter to his viewpoint.



How Anthony Watts Dismisses Evidence that is Counter to His Viewpoint - Even His Own Evidence


Look at the part I've highlighted in bold, which is probably the bit that Anthony objected to the most.  Now consider what Anthony does next in his own article.

What he does next, in the very same blog article, is "dismiss evidence that is counter to his viewpoint" Not only that, the evidence he dismisses is from his very own research, a paper on which he is listed as co-author, Fall et al (2011).

 Fall et al (2011) looked at whether siting of weather stations in the USA introduces a bias in the temperature record.  The paper suggests there is a measurable difference in diurnal variation but that station siting has no impact on the trend of average temperatures.  Other published research, by Menne et al (2010) also found that station siting does not introduce any warming bias in the temperature record.  A different but somewhat related more recent study found that the effect of urban heat islands has been factored into the US temperature record and does not distort the trend.

Anthony then goes on to explain that he dismisses his own findings reported in Fall et al and is working on finding a way to get a different result - one presumably that will not be "counter to his viewpoint".  He writes:
We know why the first effort (Fall et al) didn’t see much of a siting signal, so the second effort used a different method endorsed by the WMO, and found a strong signal. We built on the flaws of the first work, and we are preparing a paper for submission that includes dealing with the useful criticisms we learned from the discussion of the preliminary release. 

(I couldn't see Anthony getting his next paper published if he really had identified flaws and is "building on the flaws of the first work"!)

Denial by Omission


In addition, Watts selectively quotes from the abstract of Fall et al, leaving out the fact that the research found no impact on average temperature trends in his effort to dismiss evidence (even his own) that is counter to his viewpoint:

Here is Watts excerpt from the abstract, which Anthony chose to feature in his blog article:
Comparison of observed temperatures with NARR shows that the most poorly sited stations are warmer compared to NARR than are other stations, and a major portion of this bias is associated with the siting classification rather than the geographical distribution of stations. According to the best‐sited stations, the diurnal temperature range in the lower 48 states has no century‐scale trend. 
What Watts omitted was this part of the abstract, that states quite clearly that station siting in the USA doesn't affect the average temperature trends, the pluses are balanced by the minuses (my bold):
The opposite‐signed differences of maximum and minimum temperature trends are similar in magnitude, so that the overall mean temperature trends are nearly identical across site classifications.

Rebutting Watts Rebutting Watts


Deniers are still waiting with bated breath for the Watts rebuttal of Watts after it's shock and awe announcement in July last year.  (Nine months is a long time in denierland, probably requiring nebulisers).

Among the blog rebuttals of the Watts rebuttal of Watts, one comes from disinformer Steve McIntyre, who seemed a tad surprised to be listed as co-author of the Watts rebutting Watts draft paper.  Other blog rebuttals can be found below:



(It's probably not a good idea to hold your breath waiting for the publication of Watts rebuts Watts.)
