Published climate science denial ignored by Christopher Monckton @wattsupwiththat

Sou | 1:45 AM Go to the first of 5 comments. Add a comment
Christopher Monckton has issued a call to defund all the weather bureaux. He wants us all to stop monitoring weather and climate. The headline of his latest article on Anthony Watts climate conspiracy blog (archived here, latest here) is: "Time to defund the weather-forecasting rent-seekers".

What upset Christopher this time was a climate statement issued by the Royal Meteorological Society and endorsed by 33 organisations around the world. He doesn't like to be reminded that global warming is real and happening. Christopher's answer to his cognitive dissonance is to stop funding weather agencies. He'd rather not know if the sun will shine or the rain will pour tomorrow, than have to read that global warming is real and dangerous and caused by us.

Icy climate fakery from Philip Lloyd in Cape Town, @wattsupwiththat

Sou | 2:08 AM Go to the first of 28 comments. Add a comment
This time I'm going to keep it short so you can get back to watching the nasty shenanigans of Donald Trump, who seems very keen to start another war. Some chap called Philip Lloyd has written an article for Anthony Watts about temperature trends in Cape Town (archived here). (Anthony must have written the headline because he changed Cape Town to Capetown.)

Never mind about that. The article is by Philip Lloyd, who's been denying science for a long time. He's another engineer. Not the decent sort of engineer. He's the type you'll see in droves at climate conspiracy blogs like WUWT and Judith Curry's place. I've written about his particular brand of denial, e.g. in 2013 and 2015.

Philip was wanting to distract deniers from the hottest year on record by claiming that the historical temperature of Cape Town was fraudulent or something. Temperature data expert, Nick Stokes disabused him of that notion e.g. here and here. (Yes, I'm joking. Nick Stokes disabused any reasonable reader of that notion. However, deniers are not reasonable, and there's no sign that Philip Lloyd was the slightest bit interested in researching the subject.)

Bob Tisdale is Perennially Puzzled about ENSO

Sou | 11:22 PM Go to the first of 3 comments. Add a comment

Bob Tisdale has another go at his favourite person, Dana, who wrote an article about ENSO, short term variation and long term trends - on Skeptical Science.  Every time Dana mentions ENSO, Bob trots out the same old line.  Each article looks the same as every other piece he writes.  You'd think he'd have cottoned on by now.  But no.  Bob asks a number of questions on WUWT.  I'll paraphrase because it seems to be just the one question:
Why doesn't the earth cool as much from La Niña as it heats from El Niño?  
I'll add another question.  After La Niña and El Niño, when ENSO returns to neutral, why does the earth still get hotter?

Seems simple to me (and to Tom on WUWT).  If there were no global warming, this is a simplified representation of what would happen in relation to ENSO:


If Earth's temperature were rising, like there is global warming, then this is what would happen (simplified):



Bob nearly answers his own question but doesn't seem to know it:
It is blatantly obvious to anyone ... that there would be little to no long-term warming of the lower troposphere temperature anomalies for mid-to-high latitudes of the Northern Hemisphere if lower troposphere temperature anomalies had cooled proportionally during the La Niña events of 1988/89 and 1998-01.
Let's look at this chart from this WMO report showing La Niña and El Niño years.


Yes, both La Niña and El Niño years are getting hotter as are the ENSO neutral years.  Sometimes the simplest answer is the right answer.

I wonder if Bob will ever manage to connect the pieces and have a 'light bulb' moment.



For a more detailed look at ENSO, see related article here, and more here. Not to forget this or this, given Bob's latest article and ensuing comments (archived here). (Sou - Jan 14)

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 - don't get angry, Don, just get your facts straight and then people will stop laughing at you.

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


Update:

Don Easterbrook has responded with a few more fibs and putting forward Donna Laframboise, 'Steven Goddard' and the fake Oregon Petition as support. Really and truly, I kid you not.

Bacci's "Delusional Dribble"

MobyT | 2:57 PM Feel free to comment!

Talking "dribble" on climate models and tea leaves

This is (probably not) for people who listen to fake skeptics science mockers like bacci, who writes:

Image of Bacci post saying climate models are bunkum
Source: HotCopper.com

Bacci starts off talking about modelling complex systems. He says the idea that 'we' can model the climate in 100 years is 'delusional'.  (I'd have to agree that any attempt by Bacci and mates to model complex systems would indicate delusion on their part, going by his posts.  Using his own imagery, bacci tends to dribble his drivel like a drip.)

He then shifts to weather forecasting, saying that in order to 'prove' a model of centennial trends in climate, one needs to model monthly weather.

Predicting monthly trends in weather

Actually, most people (Bacci excepted) don't need a model to broadly predict weather on the monthly scale.  Next month is the start of autumn down here and we know from experience that autumn brings milder temperatures (but it can still get a bit hot).  We can even predict with reasonable accuracy that in five months time (July) the average monthly temperature in southern Australia will be cooler than the average for this month (February) and there will likely be snow on the ranges, while in the northern hemisphere the ice in the Arctic will be melting.

Feel free to check back in July and tell me how wrong my prediction is!

One source for an indication of likely rainfall patterns in eastern and south-eastern Australia on a short term scale (weeks to months) is the Bureau of Meteorology's seasonal outlooks and also their ENSO wrap up.

Fake skeptic predictions

Fake skeptics have not done very well in their predictions. Some have even been so far off target with short term predictions that the 'delusional' descriptor may be appropriate.

John McLean's Delusional Drop

For example, bacci could have been talking about computer technician John McLean.  Back in March 2011, he 'predicted' that "2011 would be the coolest year since 1956, or even earlier".  He was forecasting a drop of 0.8 degrees Celsius in the average global surface temperature in a single year, from the record high of 2010. (The global average surface temperature has risen by about 0.8 degrees Celsius in the past century.  In 2010 it was 0.62 degrees above the twentieth century average.)

As it turned out, 2011 was the 11th warmest year on record and the warmest La Nina year on record.  So much for that fake skeptic's delusion.  2011 was 0.51 degrees Celsius above the twentieth century average, whereas the average temperature in 1956 was about 0.18 below the twentieth century average.  He was out by a whopping 0.69 degrees Celsius!

Other fake skeptics' tea leaves

Bacci says he might as well read tea leaves.  Maybe that's what fake skeptics do.  SkepticalScience.com has an animated gif comparing the predictions of 'skeptics' with IPCC temperature projections and actual observations.  Fake skeptics 'tea leaf' predictions don't stack up at all well, while the different years' IPCC projections have so far all been much closer to what was actually recorded.

Animated gif from skepticalscience comparing skeptic/IPCC/observed temperatures

The skepticalscience.com article goes into more detail and is worth a read.   It discusses some of the weaknesses of IPCC projections, such as the fact that sea levels may be rising faster and the fact that Arctic ice is definitely disappearing much faster than expected.

Realclimate.org does an annual comparison of models too, looking at global surface temperature, ocean heat content and summer Arctic sea ice cover as well as early projections from James Hansen.

To sum up, complex models based on physics and constructed by experts in climate science have been very good predictors of global trends and even of regional trends.  They are not perfect but as computing power increases along with knowledge of climate the models also improve.

Important factors that climate scientists have more difficulty in predicting in the medium to longer term are the amount of greenhouse gases and aerosols we choose to pour into the atmosphere.  (Also significant volcanic eruptions that might occur in the future.) That's why they use scenarios to model climate under different permutations of future pollution.

Isaac Held's blog is a really good place to peep under the hood of climate modelling.

HotCopper Dumbest Post Award

MobyT | 5:14 PM Go to the first of 4 comments. Add a comment
This week astrayalien receives the dumbest post award for a thread he started on HotCopper science and medicine S&M forum.

An alien view?

Astrayalien promotes beliefs alien to science.  He provides a link to John O'Sullivan (another denier crank) who believes that the atmosphere has a cooling effect and that without it, earth would be 121 degrees Celsius.  (Yes, that's actually on his website!)  O'Sullivan's ideas are so ridiculous that I doubt anyone has ever bothered to refute them. (I stopped reading once I got to the bit about the atmosphere having a 'cooling effect'.)

And if you were in any doubt about the collective IQ on HotCopper, six more HotCopper-ites agree with astrayalien than disagree.


Source: HotCopper.com S&M forum

Not only that, but astrayalien also links to the website of a software developer, Christian evangelist, wedding photographer called Douglas Cotton, who he believes has overturned more than two hundred years of scientific research by 'proving' there is no such thing as a greenhouse effect. Doug doesn't publish in peer reviewed journals but that doesn't deter astrayalien.

Younglogga gallantly tried to restore credibility to HotCopper and bring the thread back to some semblance of scientific decency by referring people to skepticalscience.com and its links to peer-reviewed science, but to no avail.  Astrayalien thinks such peer-reviewed science is "complete drivel".  He only accepts 'science' from evangelical wedding photographers/software developers.  Anyone who accepts peer-reviewed science suffers 'cognitive dissonance' according to astrayalien.  (Does he know what cognitive  dissonance is?)

Resident troll Hanrahan supports astrayalien, referring to skepticalbloodyscience.com.  (Young Han cannot abide the site because it uses science to refute the 'arguments' of his mate Bob Carter.)

Genericmicrobe can't understand skepticalscience.com and wants HotCopperites to explain it!

Denmor says science is 'alarmist claptrap'.

Denial from HotCopper seems to be keeping pace with Earth's temperature. Correlation does not necessarily mean causation, but ...
