In another spurt of denier weird at WUWT, Anthony Watts from the denier blog WUWT, copied and pasted a press release about a new paper in Nature Climate Change. The paper was about warming at high altitudes.
Anthony again added some words written all by himself (archived here). He seems to be taking a renewed interest in his blog. That must be about ten sentences he's written in two days. About the same number of words he's written on his blog in the past four months or so.
Elevation-dependent warming or how some altitudes are warming faster
|Transecto Cordillera Americana TCA Source: MRI|
This time the article Anthony copied is about investigations into whether or not some high altitude regions are warming faster than average.
Anthony's headline is wrong. He wrote: "Despite ‘extremely sparse’ data, Mann’s buddy Ray Bradley seems sure that ‘High mountains are warming faster than expected ‘
Notice how he just had to get in a snipe at Professor Michael Mann who had nothing to do with the paper. That is straight from the Disinformer 101 textbook. It was applied give his mob someone else to aim at, in case they were bored with the topic of the article. However that's not what I meant when I said the headline is wrong. In the material that Anthony copied, but didn't absorb, one of the authors said:
Lead author Nick Pepin of the University of Portsmouth, U.K., says, “There is growing evidence that high mountain regions are warming faster than lower elevations and such warming can accelerate many other environmental changes such as glacial melt and vegetation change, but scientists urgently need more and better data to confirm this. If we are right and mountains are warming more rapidly than other environments, the social and economic consequences could be serious, and we could see more dramatic changes much sooner than previously thought.”There is a difference between "seems sure" and needing "data to confirm this". The scientists have found evidence that some high mountain regions are warming faster than lower elevations, but this needs to be confirmed.
Okay, Anthony's headline was about Dr Bradley and that wasn't a quote from him, it was from the lead author, Nick Pepin. Here's a part of the press release about Dr Bradley:
UMass Amherst’s Bradley adds that without substantially better information, there is a risk of underestimating the severity of a number of problems, including water shortages and the possible extinction of some alpine flora and fauna.
Professor Bradley talks about the need for better information and the risk of not knowing. That is also some way from seeming "sure".
The research was part of an effort by the Mountain Research Initiative, which you can read about here. (As a bonus there are some beautiful photographs.) It is an international collaboration funded by the Swiss National Science Foundation and hosted by the Institute of Geography of the University of Bern. This paper was co-authored by twenty-one scientists from Austria, Canada, China, Ecuador, Italy, Kazakhstan, Pakistan, Switzerland, United Kingdom, and the United States.
Here is a bit more information about the research, from ScienceDaily.com:
Records of weather patterns at high altitudes are "extremely sparse," the researchers found. There are very few weather stations above 14,700 feet (4,500 m), and long-term data, crucial for detecting patterns, doesn't yet exist above 16,400 feet (5,000 m) anywhere in the world. The authors say the longest observations above this elevation are from the summit of Kilimanjaro, which have been maintained for more than a decade by Douglas Hardy of UMass Amherst.
For this study, Pepin, Bradley and colleagues reviewed elevation-dependent warming mechanisms such as loss of snow and ice, increased latent heat release at high altitudes, low-elevation aerosol pollutants that increase the difference in warming rates between low and high elevations, plus other factors that enhance warming with elevation in different regions, and in different seasons.
They discuss future needs to improve knowledge of mountain temperature trends and mechanisms via improved observations, satellite-based remote sensing and model simulations. Noting that "many factors make it extremely difficult to determine the rate of warming in mountainous regions," the team reports the most striking evidence that mountain regions are warming more rapidly than surrounding regions comes from the Tibetan plateau, where temperatures have risen steadily over the past 50 years and the rate of change is accelerating.The work builds on previous studies over the past couple of decades. The supplementary information gives an overview of the different research about the rate of temperature rise at different altitudes in different regions. The rate of temperature increase relative to lower elevations varies from place to place and from altitude to altitude and from season to season. There is a lot to digest. For example, here's a snippet from the table in the supplementary information, listing some of the research that's been done and the various data sources (surface, satellite, models etc). (I've left off the comments column to fit here):
If you think that table was hard to read, it's even harder to read in the pdf file :(
The paper and supplementary information discusses what can be done in the future to monitor what is happening. This includes the different ways of monitoring and the strengths and weaknesses of each:
- Monitoring by surface stations, preferably with cameras attached, will provide visual information as well as metrics on temperature, precipitation etc.
- Satellite data allows monitoring of inaccessible regions, but has limitations such as not being able to "see" through clouds, which occur a lot over mountainous regions. They are also subject to orbital drift, which makes comparisons over time particularly challenging.
- The third method discussed is by modeling. Although grid size of models can mask what is happening, using downscaling, scientists can explore changes in particular regions.
All three approaches will help work out what is happening and what is likely to happen as climates change with greenhouse warming. The main hurdle is getting the data, which is one of the purposes of this paper as I understand it - discussing what data is needed and how best to obtain it.
Anthony Watts' big "rebuttal"
Anthony Watts is a science disinformer by "profession". If there is new paper on anything vaguely climate-related, he disputes it as a default position. Only rarely does he show any sign of understanding what he disputes. Anthony doesn't seem to care that he comes across as ignorant and dimwitted. His readers don't know the difference and care even less. That's all that matters in terms of blog hits.
Here is a summary of Anthony's "rebuttal":
- He claims "they seem to be focused on the Tibetan Plateau". On this first point - Anthony didn't read the paper. All he saw was Figure 1: Elevation-dependent warming over and around the Tibetan Plateau. He failed to notice the list of 86 references covering mountainous regions around the world - from China, Korea, India, Nepal, Canada, the USA, Switzerland, Austria and everything in between.
- He "wonders" if this isn’t just another hyped up claim like Himalya-gate" (sic). This is also from Disinformation 101. Anthony, the disinformer, is trying to link this paper in his readers' minds with a mistake buried deep in the WG2 report (not the physical sciences report) of IPCC AR4. Not only does this paper have nothing to do with that error, the error itself wasn't a "hyped up claim", it was a mistake that was corrected once discovered. (And it was discovered by a scientist, not by a fake sceptic.)
- Anthony claims that Banff temperature " looks to be a bit cooler". At least in the broken record that Anthony came up with. Anthony decided not to show the BEST data for Banff, because it shows that temperatures there are going up.
- Al Gore! Yep, drawing on the classic denierism of the "Al Gore is fat" type, Anthony claims that because Al Gore was wrong when he said that "Within the decade there will be no more snows of Kilimanjaro" it means that the mountains aren't warming! Anthony also claimed that "the snow is coming back to Kilimanjaro". He didn't mention that there have been massive declines in glaciers there. The impact of land use change is likely to be very limited, according to this paper in Nature.
Chasing the squirrels in Banff
The first squirrels I ever saw were in eastern British Columbia in Canada. What surprised me was how tiny they were. I was expecting them to be the size of our brushtailed possums :)
Chasing Anthony's squirrel - he wrote: "From what I can tell, they are using GHCN data for high elevation stations, such as the one from the Sulphur Mountain Weather Observatory, in Banf, Alberta." But he hasn't even read the paper let alone the references, so how can he claim to "tell" anything. If he'd bothered to open the Supplementary Information file, he'd have got a bit of a clue about where his "data" came from. Not only that, but does Anthony think that his Sulphur Mountain Weather Observatory, in Banf, Alberta is on the Tibetan Plateau? Remember, he claimed just two sentences prior, that the study was "focused on the Tibetan Plateau".
Chasing that particular squirrel a bit further, Environment Canada isn't the friendliest website for trying to get weather data or figure out what's happened at a particular location. Could be that I just haven't learnt how to navigate it. In any case, it looks to me that there were changes to the weather stations in Banff - especially during the 1990s. Berkeley Earth agrees. Here are plots from Berkeley Earth, showing raw and adjusted records.
|Data source: Berkeley Earth|
And this is what the data in Anthony's chart looks like. I've plotted it from the data in the GISTemp station selector website:
|Data source: GISS/NASA|
I've just noticed that in the WUWT comments, Dave in Canmore tells Anthony that he's wrong, too. Would you agree that Anthony went looking for a station somewhere that he could claim falsified the research? Even if the temperature in Banff wasn't going up (which I doubt), would a single location mean that no temperature anywhere else could be rising?
Perhaps he can tell the ski resorts in Switzerland and Austria that the melting snow (and lack of snow) isn't because it's getting hotter.
Squirrels on Kilimanjaro
I don't think there are any squirrels on Kilimanjaro. It's only at WUWT you'd be urged to chase one there. If you're curious about the glaciers on Kilimanjaro and are wise enough not to accept anything you read at WUWT without double and triple checking, read on. Some glaciers have shown a dramatic decline since the beginning of last century. Here's a chart from Cullen13, showing how much smaller they've got since 1912:
|Fig. 1. Glacier extent on Kilimanjaro in 1912 and 2011. Glacier names with an asterisk do not appear in Klute (1920) and are described in the text. The interpretation of the glacier extent for 1912 as defined by Hastenrath and Greischar (1997) is shown as a dashed line (blue) for comparative purposes. The nomenclature for each glacier used by Klute (1920) is given, while the names of four glaciers introduced after this time are indicated using *. Source: Cullen13|
Tourists are warming the Tibetan Plateau!
Anthony isn't shy about looking stupid, is he. He wrote: "…one wonders if similar weather observatories in Tibet aren’t simply seeing the effects of increased tourism, resulting in land use modification."
Does Anthony know how big the Tibetan Plateau is? It's about 2.5 million square kilometers, which is more than five times bigger than Anthony's home state of California - or about 1/4 the size of the USA or Canada, or more than twice the size of South Africa and more than ten times larger than the United Kingdom. Anthony claims "it's tourists" changing the climate in that remote and largely unpopulated region, yet you'll see his deniers at WUWT claiming people can't influence climate! (A 1990 estimate of population put it at less than 5 million people, one tenth that of South Africa which has only half the area.)
It reminds me of Anthony's UHI classic, when he claimed that a couple of people doing research in a remote part of eastern Antarctica, who shared an unheated tent - caused an "urban heat island" effect more than 3,000 km away on the other side of the Antarctic continent.
Why does Anthony Watts post such utter rubbish?
The main purposes of Anthony Watts blog, WUWT, is to disinform and mock science and scientists. From a poll of WUWT readers - 98.4% are declared fake sceptics. They are the wilfully ignorant when it comes to climate science. They are the people who don't want to know about science. (If they wanted to learn about climate science they'd not be reading WUWT.)
Anthony's typical readers wouldn't shift their thinking even if Anthony did an about-face and became pro-science. They'd just rant for a bit and then go elsewhere. Not to Judith Curry's blog because there are too many words there. WUWT-ers find reading words a bit hard going and would probably regard Judith's blog as denial that's a bit too "inti-leckshull". More likely they'd settle for some other conspiracy theory website. One that has lots of pictures, where they can post whatever random "thought" happens to be in their head at the time, and where it's unlikely that their random "thought" will be mocked by anyone else (or noticed).
All of which leads me to the WUWT comments - many of which are mind-numbing.
From the WUWT comments
Have you got your head-vice in place? Here you go. The WUWT-ers are eager to take part in the competition for the dumbest comment.
wickedwenchfan says that the scientists are stupid. Don't they know that it's cold in the mountains? And how can CO2 have an effect when the air is so thin?
April 23, 2015 at 5:02 am
Stupidity in the extreme. Mean temperature drops with altitude (hint, atmospheric pressure not GHG’s is responsible for raised surface temperature) I would be surprised if any mountain above 5000m has mean temperatures above freezing or ever will. Let’s face it, even if you believe in back radiation you would have to be wondering just how many extra CO2 molecules are accumulating above that elevation to be having an impact.
Patrick is another one who reckons that mountains can't get warmer. Any fool knows that mountains are cold!
April 23, 2015 at 5:38 am
Oh dear lord! More models. For every 1000ft increase in altitude/elevation, there is a ~1C DROP in [temperature]! If anything they are COOL and will always be so.
Charlie tries out sarcasm to let everyone know that he just knows that it's colder up in the mountains, those silly scientists don't know nuffin'.
April 23, 2015 at 10:56 am
It’s amazing in Vermont generally its colder on the top of the mountains than down in the valleys. It also snows more there. I don’t know if this strange phenomenon happens on other mountains. I’ll do some research and let you know.
philincalifornia talks about stratospheric mountains
April 23, 2015 at 9:23 am
Don’t the radiative cooling effects of CO2 increase with altitude ?
EternalOptimist is a confused little WUWT-er.
April 23, 2015 at 10:48 am
Let me get this right.
Urban Heat Island does not exist
but Upper Himalyan Heat Island does exist
Ray Boorman carefully explains why temperatures are reported as anomalies. It's so you won't notice how cold it is up in the mountains! Bet you didn't know that :D
April 23, 2015 at 4:13 pm
Yes Patrick, & that is why these studies rarely have figures showing the actual temperatures, just ones showing the anomalies. The authors are afraid that no-one would would take any notice if they said the average temperature at 4000m had risen from -x.yzC to -x.yaC. And personally, I don’t blame them for being afraid, because the differences are irrelevant in the real world. A below freezing climate is still very cold, no matter how much it has warmed relative to its prior average temperature.
There were some only slightly less stupid comments - from people who didn't bother reading the article or the paper. Despite the paper listing studies that used satellite data, and despite a very lengthy section on satellite data in the supplementary information, ferdberple goes on a rant, ignoring what the scientists have to say:
April 23, 2015 at 6:49 am
Don’t we already have satellites measuring temperatures at altitude globally? How come these are ignored and instead climate science relies on sparsely sited land-based thermometers, often contaminated by urban growth?
It doesn’t make any sense, scientifically. Why rely on the worst possible measurements to conduct your science, while ignoring the most exact measurements?
It seems to me that the “high mountains are warming faster than expected” says a lot more about the expectations of the researchers than it does about the high mountains.And a WUWT mod chimes in with a reply, demonstrating his or her anti-science stance - and ignorance - and conspiracy ideation that WUWT is known for:
It’s Colorado rocky mountain high
I’ve seen it raining fire in the sky
Friends around the campfire and everybody’s high
Rocky mountain high
[Climate science would use the satellite records – as soon as the satellite records show something climate science wants to show. .mod]Thing is, of course, that satellite data is being used, as described by the scientists. And those data are no more accurate than any other measurements and in many cases a lot more difficult to work out. And when there are clouds it gets even harder, unlike surface instruments. Anyway, Ferd's wrong comment about satellite data got a whole heap of echos from other silly WUWT-ers who didn't bother with what the paper was about, any more than Ferd or Anthony Watts.
Here's an example of more typical conspiracy theorising WUWT-style from Ray Boorman. He claims, contrary to what is written in the paper and the supplementary information and the press release - that the scientists want money not measurements. He's wrong:
April 23, 2015 at 3:47 pmIf only Ray had read the abstract. Or perhaps he did and is banking on the fact that no-one else from WUWT would do so. Nowhere is there mention of money - it's all about data. For example in the abstract:
Actually Fred, I would say a big reason they pick on the high mountains is that, just like the polar regions, there are so few actual weather stations up there. The lack of real data allows the “warmmunists”, to attempt to feather their own nests by demanding more taxpayers money be spent on research into the “problem”. A real scientist would ask for more weather stations, but this mob ask for research grants instead.
We discuss future needs to increase knowledge of mountain temperature trends and their controlling mechanisms through improved observations, satellite-based remote sensing and model simulations.
Paul Homewood tries to do "funny":
April 23, 2015 at 5:48 am
Perhaps the mountains are getting lower!
Failed weatherman, Joe Bastardi, verges on hysteria, writing some nonsense or other that I doubt anyone can make sense of. He talks about "this guy" but doesn't say which of the twenty one "guys" he's referring to:
April 23, 2015 at 5:18 am
Since the NCEP CFSR SHOWS NO WARMING
Someone must be cooling equally fast.
Does the guy even stop to think about that. Its like Dr. Mann with his lack of medieval warming. If there was no warming, and you are claiming the warming observed was “local” then why cant you tell us where the cooling was. The bigger question is why doesnt anyone in the scientific community actually ask these guys that question.
So mr Bradley, given the NCEP CFSR is one of the premier grids to measure temps out there, and showed the warming after the flip in the PDO to warm in the 80s and 90s, if what you are saying is right and the last 10-20 years there is no statistical warming, WHERE IS YOUR COMPENSATING COOLING to give credence to your worse than ever High ground disaster scenario.
Timed amazingly to capitalize on the warm ring and resulting western warmth. Will likely go the same way as post 2005 hurricane hysteria, or post 2011 tornado hysteria. But grabs headlines now, that no one bothers calling them on with intuitive questions, or later when the PDO goes back and its frigid in the west.. Then the warming faster than we thought will shift to where its warm
Its Despicable, Deceptive, Delusional, and a sheep like scientific community that wont ask basic questions is complicit
There's more of Joe "ice age cometh" Bastardi raving on about sunspots and plant food and the big cooling that he said was coming, over at Media Matters. Just for Joe, here is a chart I did the other day of CO2 and surface temperature - so you can go ahead and believe it!
