An economist should know better, maybe ...but what about Anthony Watts?

Sou | 1:59 PM Go to the first of 10 comments. Add a comment


On WUWT today Anthony Watts seems to be trying to make up for his rampant promotion of disinformation - but is he?


An economist should know better, maybe...but what about Anthony Watts?


Anthony puts up an article about someone on a radio show who doesn't understand the greenhouse effect.  She said a car heats up in the sun because of greenhouse gases, which is woefully wrong.  Someone who works for the Natural Resources Defense Council should know better. A car with all the windows and doors closed will heat up by incoming radiation from the sunlight.  As long as it's in the sun it will stay hot until you open the doors and windows to diffuse the heat (convection).



Ridicule is both powerful and satisfying...


Anthony needs to look in a mirror.  The following aren't rare occurences.  They are typical of the disinformation and ignorant ramblings he spews out daily to pollute cyberspace:




Pinocchio with long nose
Pinocchio by André Koehne
Lots more from Anthony Watts, who is so paranoid about "real science" that he enrolls his dog, Kenji, to spy on his behalf at the Union of Concerned Scientists. A man who can barely attract anyone but science deniers and bans people who have no tolerance for his anti-science nonsense. A 'free market' man who despises governments but wants to run squawking and squealing to the government when someone mocks his scientific ignorance.


PS Anthony's not doing a very good job of educating his readers about the greenhouse effect - this from Latitude who says:
May 23, 2013 at 12:04 pm  so tell me again how many people believe in global warming………I’m just curious to know how many total idiots we have

It's also nice to see Kurt in Switzerland vindicating my snark blog, writing:
May 23, 2013 at 11:38 am  ...Ridicule is both powerful and satisfying, especially when the target is begging to be shot.



"Charts are so confusing!"

Update: Anthony Watts Classic: those baffling temperature anomalies


I'd been looking for this article for a while - and thanks to Lars Karlsson in the comments below here it is.  Scroll down the page for this real gem in which different baselines get the better of Anthony:
I was surprised to learn that only 5% of the GISS data-set was on the cool side of zero, while a whopping 95% was on the warm side. Even with a rising temperature trend, this seems excessive.
When the distribution of data is so lopsided, it suggests that there may be problems with it, especially since there appears to be a 50% greater distribution on the cooler side in the HadCRUT data-set.



(Kenji whispers to Anthony: GISTemp uses a baseline of 1951-80 while HadCRUT uses a baseline of 1961-90, so of course the temperature anomaly will move above the baseline sooner with GISTemp than for HadCRUT.)



Kenji, the scientific dog, must be so embarrassed.

WUWT Gets Weirder by the Day - Now burning fossil fuels doesn't produce CO2?

Sou | 11:46 PM Go to the first of 7 comments. Add a comment

A new bout of craziness has broken out on WUWT, this time led by Girma Orssengo, PhD.  Girma posted an article entitled:  Claim: How the IPCC arrived at climate sensitivity of about 3 deg C instead of 1.2 deg C.

Girma's sixty year cycle based on sixty years of observations!

Nice headline.  But Girma proceeds to do something else entirely - as many commenters point out.  He reckons there's a sixty year cycle, based on his 'analysis' of temperatures over the sixty years between 1940 and 2000 or thereabouts.  I kid you not!  I won't try to delve more deeply - that should be enough to give you the picture.  If you want to know how the IPCC report deals with climate sensitivity - click here.

What's even more ridiculous is what happens in the comments.  Based on the comments, Girma Orssengo, PhD, in one of the most convoluted cases of circular reasoning one can imagine, believes:
  • Burning fossil fuels doesn't produce carbon dioxide
  • Carbon dioxide is being outgassed by the oceans (oceans in fact are absorbing CO2)
  • Temperature is rising by magic
  • Climate sensitivity is the doubling of temperature from a rise in CO2 that is being outgassed by the oceans as a result of the rising temperature (and that are in fact absorbing, not emitting CO2).

Burning fossil fuels doesn't release CO2 - what?

After writing his article and making numerous follow up comments explaining how he works out climate sensitivity (to CO2 forcing), down in the comments Girma makes this statement - pretty funny for someone who stresses his PhD (my bold):
Girma says:
May 18, 2013 at 8:59 am
Don Easterbrook
I am not saying CO2 is causing the warming. I believe it is the warming that is causing the increase in CO2 concentration, as the vostok ice cores show. The CO2 concentration will drop when the temperature falls.
What I'm trying to figure out is how that works.  First of all one has to decide that the following chemical reaction doesn't happen:

hydrocarbon + oxygen ---> CO2 + H2O


How is the rise in temperature increasing CO2? (In Girma's reality - not yours and mine)

Then one has to figure out how the warming is causing the increase in CO2 concentration.  Girma explains:
As the temperature increases, more CO2 is released from the oceans (where it is about 50 times than in the atmosphere) increasing the CO2 concentration in the atmospheric.
As the temperature decreases, more CO2 is dissolved in the oceans decreasing the CO2 concentration in the atmosphere.
When temperatures change as a result of forcings other than CO2, carbon dioxide does outgas from the oceans as they warm.  Small perturbations in temperature from orbital changes can produce much larger shifts in temperature because of this CO2 feedback - ending an ice age or plunging into one.  Read more about the greenhouse effect in this booklet from the Bureau of Meteorology.

But that's not what's happening now.  The oceans aren't releasing CO2.  They are absorbing about half the CO2 we pour into the air each year at the same time as they are warming up.  That's evidenced by the fact they are getting more acidic.  However, Girma doesn't even seem to think that burning hydrocarbons produces carbon dioxide and he's ignoring that little detail of ocean acidification.

So how does Girma explain the rise in temperature?  Well, that's a puzzle.  He refers back to his oscillation - but as Russ R. saysShouldn’t the trend over a complete 60 year cycle be zero? Otherwise, it must be magic.

Just what does Girma mean by climate sensitivity?

Next one has to try to figure out what Girma's original article on climate sensitivity is all about.  Climate sensitivity is the rise in temperature from a doubling of CO2 (in this case).  Given Girma has said that it's the temperature increase that's causing more CO2, then his climate sensitivity can't be a measure of temperature rise from a doubling of CO2.  Maybe it's the doubling of CO2 from a given temperature rise?  Weird.

The Usual

More fun from the comments:

Slayer Graham is outed by Anthony Watts when he says:
May 18, 2013 at 5:57 am  All sensitivity figure are wrong, because there is no linkage between CO2 and temperature.
REPLY: John O’Sullivan, leader of the Principia cult, there’s no need to hide behind a fake email address. We always know who you are here....(inserts email rejection etc here)...Anthony.
Emeritus Professor Don Easterbrook is getting nuttier (and shoutier) by the day if that's possible.  Despite apparently also denying greenhouse gases (like the slayers do), he remains a favourite of Anthony - and says:
May 18, 2013 at 6:51 am  What ever happened to ’cause-and-effect’ in science? Just because temperature went up and CO2 also went up over the same period doesn’t make a basis for calculating how much temperature will go up as CO2 increases! This whole analysis is based on the false premise that temperature is a function of CO2. Why don’t we do the same analysis for the period 1945 to 1977 and calculate how much COOLING occurs with increase in CO2? And why don’t we calculate for the period 1880 to 1915 how much COOLING occurs with increase in CO2? And why don’t we calculate for the Maunder Minimum how much COOLING occurs with increase in CO2? You get the idea–the notion that temperature is a function of CO2 is invalided until you first show a cause-and-effect relationship between the two!
Richard M is in some degree of chaos and says:
May 18, 2013 at 8:14 am  Climate sensitivity is not a constant. It is variable and dependent upon other factors. That is due to the chaotic nature of climate. When near an attractor state it will be small. The further away it gets the higher it will be for any forcing.

A History of "Cyclic" Girma

Let's finish with a bit of history from Girma on realclimate.org. I suspect Jim thought Girma was sending up deniers.  We now know Girma was being Very Serious :D


Girma says:
Global mean temperature pattern is cyclic as shown in the following graph!  http://bit.ly/cO94in
CO2 emission has nothing to do with global mean temperature as its patterns before and after mid 20th century, before and after wide spread use of fossil fuel, are nearly identical.
[Response: Brilliant in all regards.--Jim]

Here's his 'following graph' (click to enlarge, if you dare!)

Denier Don is Angry

Sou | 5:09 PM Go to the first of 2 comments. Add a comment

Don and his cooling fetish


Another gem from WUWT.  David Deming is sticking up for Don Easterbrook, who apparently gave a presentation to the Washington State Senate Energy, Environment and Telecommunications Committee.  In response, faculty members of the Western Washington University geology department wrote a letter to the Bellingham Herald (see below).  This isn't the first time.  Don's a repeat offender and has to know it.


Greenland is not the whole world

From reading the letter to the Bellingham Herald, it appears that the Emeritus Professor tried to convince the government committee that local temperature trends on a summit high in Central Greenland are the same as temperature trends for the entire world.  This is the WUWT chart Don trots out from time to time and probably the one referred to by the WWU Geology Faculty :


When Don refers to Central Greenland temperatures he writes stuff like this:
Keep in mind that these are temperatures in Greenland, not global temperatures. However, correlation of the ice core temperatures with world-wide glacial fluctuations and correlation of modern Greenland temperatures with global temperatures confirms that the ice core record does indeed follow global temperature trends and is an excellent proxy for global changes.
Umm, no, Don - not at all.  Arctic amplification operates in the Arctic and the temperature record on the summit of Greenland is an excellent proxy for the enormous ice sheet way up on the summit in Central Greenland!

Here is what Marcott et al wrote in their FAQ on Realclimate.org recently:
Just as it would not be reasonable to use the recent instrumental temperature history from Greenland (for example) as being representative of the planet as a whole...
Not only that, but after years and many, many people pointing out another persistent error Don makes, he still refuses to fix the incorrect label on his 'chart'.  The record is for 'Years before present' which in this case follows the convention of being 1950.  So the chart starts in 1855 not 1915.

How Don loses his cool (prediction)


Anyway, of all people Cliff Mass took Don to task and Don responded with a lot of bluster and shouting and waving of arms.  As Anthony Watts observed:
I’ve never seen him this angry. – Anthony
Here is one of the charts to which Cliff Mass referred when he criticised Don's liberality with facts and his delusion about global cooling:


SkepticalScience has done some analyses of Don and his 'cooling' predictions, for example, here.

(Don also has some strange notion that Cliff Mass has some 'models' that predict a rise in global surface temperature of one degree Fahrenheit per decade.  I don't know where Don got that idea from - probably the same place as his 'cooling' predictions.)

Here is a chart of actual warming from NASA's GISS Surface Temperature Analysis:




The Letter from the WWU Geology Faculty


Here is the letter to which David Deming objected.  I had to get this from google's webcache because the Bellingham Herald site seems to be down:

By WWU GEOLOGY FACULTY — COURTESY TO THE BELLINGHAM HERALD

On March 26, 2013, a long-retired faculty member of our department, Don Easterbrook, presented his opinions on human-caused global climate change to the Washington State Senate Energy, Environment and Telecommunications Committee at the invitation of the committee chair Sen. Doug Ericksen, R.-Ferndale. We, the active faculty of the Geology Department at Western Washington University, express our unanimous and significant concerns regarding the views espoused by Easterbrook, who holds a doctorate in geology; they are neither scientifically valid nor supported by the overwhelming preponderance of evidence on the topic. We also decry the injection of such poor quality science into the public discourse regarding important policy decisions for our state's future; the chair of the committee was presented with numerous options and opportunities to invite current experts to present the best-available science on this subject, and chose instead to, apparently, appeal to a narrow partisan element with his choice of speaker.

We concur with the vast consensus of the science community that recent global warming is very real, human greenhouse-gas emissions are the primary cause, and their environmental and economic impacts on our society will likely be severe if we don't make significant efforts to address the problem. Claims to the contrary fly in the face of an overwhelming body of rigorous scientific literature.

We intend no disrespect to Easterbrook personally. We appreciate his previous service to our department and to Western. His present appointment as emeritus professor was made in light of his long-standing history at WWU. But people of the state of Washington need to understand that Easterbrook's ideas on anthropogenic global warming have not passed through rigorous peer review in the scientific literature. Additionally, Easterbrook's claims in this forum and elsewhere require the existence of a broad, decades-long conspiracy amongst literally thousands of scientists to falsify climate data and to prevent publication of opposing research. This opinion demonstrates a profound rejection of the scientific process and the fundamental value of rigorous peer review, and is also simply wrong.

Science thrives on controversies; it rewards innovative, unexpected findings, but only when they are backed by rigorous, painstaking evidence and reasoning. Without such standards, science would be ineffective as a tool to improve our society. It is worth acknowledging that nearly every technological advance in modern society is a direct result of that same scientific method (think the Internet, airplanes, antibiotics, and even your smartphone).

Easterbrook's views, as exemplified by his Senate presentation, are a stark contrast to that standard; they are filled with misrepresentations, misuse of data and repeated mixing of local vs. global records. Nearly every graphic in the hours-long presentation to the Senate was flawed, as was Easterbrook's discussion of them. For example, more than 100 years of research in physics, chemistry, atmospheric science and oceanography has, via experiments, numerous physical observations and theoretic calculations, clearly demonstrate - and have communicated via the scientific literature - that carbon dioxide is a powerful greenhouse gas; its presence and variations in Earth's atmosphere have significant and measureable impacts on the surface temperature of our planet. Alternatively, you can take Easterbrook's word - not supported by any published science - that the concentration and effects of carbon dioxide are so small as to not matter a bit.

In a specific example, Easterbrook referred to a graph of temperatures from an ice core of the Greenland ice sheet to claim that global temperatures were warmer than present over most of the last 10,000 years. First, this record is of temperature from a single spot on Earth, central Greenland (thus it is not a "global record"). Second, and perhaps more importantly, Easterbrook's definition of "present temperature" in the graph is based on the most recent data point in that record, which is actually 1855, more than 150 years ago when the world was still in the depths of the Little Ice Age, and well before any hint of human-caused climate change.

As the active faculty of the Western Washington University Geology Department that he lists as his affiliation, we conclude that Easterbrook's presentation clearly does not represent the best-available science on this subject, and urge the Senate, our state government, and the citizens of Washington State to rely on rigorous peer-reviewed science rather than conspiracy-based ideas to steer their decisions on matters concerning our environment and economic future.

Someone tell Don and WUWT crowd - correcting the content of what people say is not (necessarily) the same as a "personal attack".

Watts is Whopping Mad (Crazy) after Marcott et al - Must be the Heat!

MobyT | 8:39 AM Go to the first of 18 comments. Add a comment
NOTE: The Marcott et al (2013) paper and supplementary material is available at Science and an FAQ is now available on RealClimate.


Comment: 1 April 2013Marcott for Dummies is out.  However, Anthony Watts (in his seventeenth protest article) and the Auditor demonstrate that even after all this time and all their protests they still haven't even read the paper, claiming that Marcott et al "finally concede" something that was stated at the outset in the paper itself (page 1198).

The Auditor and his brigade are not at all grateful for the extra effort made by the researchers to explain their work to the layperson, and appear to be still trying to claim we are in the middle of the Little Ice Age and focusing on core tops instead of the core!

They obviously do not understand the connect between the modern record and the paleo record, even after years of nit-picking climate research.  And I wonder will the 8% Dismissives heed this part of the FAQ:
Just as it would not be reasonable to use the recent instrumental temperature history from Greenland (for example) as being representative of the planet as a whole...
The Auditor's cronies continue to make wild unfounded accusations. Conspiracy ideation most definitely (no wonder they don't like Lewandowsky and others showing them up in their true colours).

Click here for an expanded version of this comment.


Update 2+  So far there are now three four five six seven eight nine ten eleven twelve thirteen fourteen fifteen sixteen seventeen eighteen nineteen twenty twenty-one twenty-two twenty-three twenty-four twenty-five twenty-six twenty-seven twenty-eight WUWT protest articles not counting the sleazeball's (approaching this might even beat the number of protests against the Lewandowsky et al paper).  The first few are touched on in this article.

(Comment 20 March 2013: I have looked through the WUWT articles and a lot of the comments.  Anthony Watts, his guest posters and commenters provide an excellent illustration of warped mental models, ignorance, illogical thinking, dogmatism, conspiracy ideation, a preference for coloured pictures and avoidance of text, and the Dunning Kruger effect as well as the lynch mob mentality.  It is also apparent that he has successfully rid his blog of all but maybe one person who is willing to consider scientific research.  Watts' blog is aimed squarely at the bottom 8%.)

Of the rest, as with all the early protests, none of the protesters has indicated they understand the paper.  Neither are the protesters interested in the overall reconstruction.  It's the early part of the reconstruction that has filled in the gaps.  There are already several reconstructions of the last several centuries, some even going back 1500 to 2000 years.  In fact the protesters seem to be focusing not on the main substance of the paper but on the past 100 years or so.  Odd, don't you think?

Now they are focusing entirely on this century rather than the entirety of the Holocene.  If I understand Watts/McIntyre correctly, they are saying that there is an "error" in Marcott et al, which means earth hasn't been warming after all and we are actually still in the Little Ice Age.

  • Protest 6 is almost identical to Protest Number 4. 
  • In Protest Number 7, Willis Eschenbach wants the raw data in the published paper, not satisfied with it being provided as a supplement.  Steve McIntyre is, as usual, "baffled".  
  • In Protest Number 8, Fred Singer misquotes Marcott so he can shoot him down.  Singer 'suspects what they did was' without appearing to be in the least interested in looking at the paper to see if what he 'suspects' was fact. 
  • Watts returns with Protest Number 9. Watts cannot figure out how anyone could know that the world has got a lot hotter over the past few decades, forgetting about the thermometers that were giving him so much grief only a few weeks ago, the melting arctic and all the other signals of our warming world.  Neither can he understand how a paper jointly authored by four people and published in 2013 could differ in the slightest degree (sic) from the lead author's PhD thesis published two years earlier.
  • Watts' Protest Number 10 is based on The Auditor's obsessive 'speculation' despite his being 'unable to replicate some of the recent features of the Marcott zonal reconstructions', though he admits it 'may be a difference in methodology'.
  • In Watts' Protest Number 11, Anthony shows that The Auditor has been fiddling with numbers (ignoring the substance of the paper) and posits he has found a 'statistical processing error (selection bias)'.  Makes me think of the saying: "Fools rush in where angels fear to tread'!
  • In Watts' Protest Number 12, Anthony proclaims that The Auditor has found an 'error'.  In fact he seems to be saying we have not yet emerged from the Little Ice Age!!!  (Fools rush in!)  Prof Peter Clark, co-author of the Marcott et al paper, has said they will prepare and provide an FAQ (a Marcott et al for dummies) which may (or may not) help McIntyre's 'bafflement'.

Near enough is good enough if it fools enough! (see below)



A paper published in the current issue of Science is getting some publicity.  According to this recent research, in just a few decades we have managed to extricate ourselves from one of the coldest periods since civilisation began to begin the hottest period.  And who knows when it will stop getting hotter.

The authors, Shaun A. Marcott, Jeremy D. Shakun, Peter U. Clark and Alan C. Mix have done a reconstruction of Holocene temperatures in a paper titled "A Reconstruction of Regional and Global Temperature for the Past 11,300 Years".  You can get the paper and supplementary data here (subs required).

Here are two diagrams from the paper, showing one of their analyses.  A shows the past 2,000 years compared with Mann et al (2008). B shows the same but going back 11,500 years before present (1950). (Click on any of the images in this article to see a larger version.)



Globally stacked temperature anomalies for the 5° × 5° area-weighted mean calculation (purple line) with its 1σ uncertainty (blue band) and Mann et al.'s global CRU-EIV composite mean temperature (dark gray line) with their uncertainty (light gray band).

The findings are not earth-shattering in that the research accords with what is already known.  It is a very valuable contribution because it adds to and greatly refines existing knowledge.  The beauty of the research is that it uses proxies from 73 sites around the globe, whereas previously much of what was known about temperatures in the early Holocene was based on ice cores or other more limited data.



What the Papers Say

Justin Gillis of the New York Times has a written short article on their findings.  Other articles can be found Dot Earth (NY Times), Mother Jones, New Scientist, CNN and the LA Times, among other places.

What Science says

From the Editor's Summary in Science:

Exceptional Now
The climate has been warming since the industrial revolution, but how warm is climate now compared with the rest of the Holocene? Marcott et al. (p. 1198) constructed a record of global mean surface temperature for more than the last 11,000 years, using a variety of land- and marine-based proxy data from all around the world. The pattern of temperatures shows a rise as the world emerged from the last deglaciation, warm conditions until the middle of the Holocene, and a cooling trend over the next 5000 years that culminated around 200 years ago in the Little Ice Age. Temperatures have risen steadily since then, leaving us now with a global temperature higher than those during 90% of the entire Holocene.

The paper's abstract:
Surface temperature reconstructions of the past 1500 years suggest that recent warming is unprecedented in that time. Here we provide a broader perspective by reconstructing regional and global temperature anomalies for the past 11,300 years from 73 globally distributed records. Early Holocene (10,000 to 5000 years ago) warmth is followed by ~0.7°C cooling through the middle to late Holocene (<5000 years ago), culminating in the coolest temperatures of the Holocene during the Little Ice Age, about 200 years ago. This cooling is largely associated with ~2°C change in the North Atlantic. Current global temperatures of the past decade have not yet exceeded peak interglacial values but are warmer than during ~75% of the Holocene temperature history. Intergovernmental Panel on Climate Change model projections for 2100 exceed the full distribution of Holocene temperature under all plausible greenhouse gas emission scenarios.

What Deniers Say

Deniers really don't like the Marcott et al paper.  Already Anthony Watts has posted five six seven eight nine ten eleven twelve thirteen fourteen fifteen sixteen seventeen eighteen nineteen twenty twenty-one twenty-two twenty-three twenty-four twenty-five twenty-six twenty-seven twenty-eight articles in protest. (See update below).

Article 1: Watts is Wrong, Wrong and Wrong again!

Watts Wrong !

In Anthony's first article he scoffed at the Mother Jones headline then demonstrated he hadn't read either Mother Jones or the paper itself, writing:
Yes, be afraid, very afraid, of that “unprecedented” (there’s that word again in the abstract) 0.7C temperature rise is the message I suppose.
No Anthony, you suppose wrong.  The take away message of most people is two-fold.

  1. The bigger message (for the general public) is the current rate of change is unprecedented in the Holocene (and probably in millions of years).  
  2. The second message is that if it isn't already, the world will soon be hotter than at any time since the beginning of civilisation.

Watts Wrong 2

Then Anthony adds to his errors, writing:

...One potential problem is that the pollen data median sampling of 120 years, which is 4x the 30 year climate normals periods used today. That’s pretty low resolution for a study that is focusing on 2000 years and leaves lots of opportunity to miss data.
Wrong again, Anthony.  The study does not just focus on 2000 years, it looks at the entire Holocene.  It looks at 11,500 years.  (And what is he on about 'missing data'?  The data is what the data is and is discussed at length in the paper and supplementary materials.)

Watts Wrong 3

Anthony compounds his errors by getting it wrong once again (all these quotes are from a single paragraph, incidentally.)
Further, when they say the last 100 years was the warmest (with higher resolution data) they really aren’t comparing similar data sets when the other data has a 120 year median sampling.
No Anthony.  "they" didn't say the last 100 years was the warmest.  Marcott et al's research suggests that we may only now be approaching the highest temperatures, which according to their research occurred during the Holocene Optimum (between about 9,000 and 5,000 years ago).

Article 2: JustNotTheFactsWUWT

In his second article, guest poster (?) "justthefactswuwt" complains about something in the CNN report of the paper.  I was not able to work out the passage that justthefactswuwt was complaining about.  He said that CNN attributed warming pre-1950 to human causes, but didn't post any passage that actually said that. (In any case, there was undoubtedly some human influence on the temperature rise before 1950, given that CO2 rose from 280 prior to industrialisation to 316 in 1959.)

Article 3: Watts third strike - and he's out (with the fairies)!

Watts reverts to form in his third article.  Do you recall the comment he made in his first article?
...they really aren’t comparing similar data sets...
Not heeding his own "advice", Watts proceeds to tack Marcott's chart onto a denialist's clumsy (and faulty) drawing of past temperatures on Central Greenland's ice sheet:


Too wrong for words

  • Is Watts really that ignorant, even after blogging on climate for several years? Does he really think that global temperatures fluctuated by more than 3 degrees Celsius in the past 9,000 years?  Does he really not know that he was trying to compare temperature trends on Central Greenland's ice sheet with a global reconstruction?
  • How does he justify chopping off 9,500 years of the Marcott et al reconstruction of global surface temperature and superimposing what's left of it onto some denier's drawing of temperatures in Central Greenland?
Not only that, but he claims his drawing is from Alley (2000), which it most certainly is not.  The chart may be derived from GISP2 data, but is incorrectly labelled (before present = before 1950 not before 2000).  The data used is based on this - the temperature in Central Greenland - not global temperature.  

Here is a chart of the Central Greenland (GISP2) temperature for the full period covered by Watts' denialist drawing, based on this data accessed from this site, with the rectangle showing Watt's cutout period above:



For comparison, here is a chart of the full data set of Central Greenland temperatures from the same source as referred to by Alley (2000), with a rectangle showing the above time period:



Neither of the above can be used to indicate global temperatures.  They represent temperatures on the ice sheet in Central Greenland.

It must be the heat

Anthony Watts seems to be getting more and more erratic and silly as time goes by.  Must be the heat.


Update: Two more protest articles on WUWT

You could hear fake skeptic screeches zooming around cyberspace when Marcott et al compared their global reconstruction to the Mann et al global reconstruction.  So what do the fake skeptics do in "protest"?  At WUWT they turn around and say "we'll show you!" and proceed to:

  • tack a single site arctic temperature series onto a global reconstruction and
  • tack a single site modern land based record onto sea surface temperatures of a 15,000+ year paleo proxy series (single site).
Here are the gory details:
1. Don Easterbrook has effectively repeated Watts' third post, comparing a global reconstruction with a single location in the Arctic (using the same flawed drawing of the latter). (Update) Don is persisting with this silliness in yet another post, apparently arguing the average global surface temperature of earth is around minus 30 degrees Celsius /s.
2. David Middleton has selected a single proxy set, Marcott No.2 from Barron et al. 2003 N. Coastal California High Res. Holocene/Pleistocene Oceanographic Data - 41.682 N, 124.930 W, 980 m water depth.
David plots the published sea surface temperature (SST) for Marcott No. 2 (which starts about 210 years ago and goes back 15,000 years or so) and tacks on a temperature series from a land-based location, Grants Pass (42.4 N,123.3 W) which goes back to around 1890 (approx 120 years).  
Then David reduces the nearby land surface temperature record to a single data point for some reason (how/why he selected that temperature data point he didn't say - maybe he took the mid-point of the fast rising series). 

Near enough is good enough if it fools enough! 


David Middleton hasn't clarified why he did what he did, tacking on a single modern land-based surface temperature series to a single paleo series of sea surface temperatures. It could be the same reason that Don Easterbrook and Anthony Watts tacked the Marcott et al global reconstruction onto a reconstruction of temperatures in Central Greenland. A "near enough is good enough if it fools enough" philosophy not uncommon with fake skeptics.

The commenters seem to be concluding that Don and David have discovered 'flaws', but no-one has identified just what those supposed 'flaws' are.
