To natural born critics AGW is the gift that keeps giving. It would be cruel to say these papers all exhibit unworldly qualities because that is inevitable if your purpose is to generate a virtual reality with computer modeling. But, as the old saying goes, you have to be cruel to be kind; so some of these papers are speculative and unrealistic; others are eristic and the rest egregious in intent or execution. A scientific theory such as AGW is, like all human endeavours, only as good as its best examples; the following papers, all peer reviewed, represent the best of AGW. The papers are in no particular order, or lack thereof, of merit.

… š® UPDATED with GLOBAL values! The questions get bigger. (See below) July 18th.
Frank Lansner has been a busy man, and he’s asking some very thought provoking questions.
The Northern Hemisphere has a ratio of 40% land to 60% oceans, and the Hadley Met Centre seems to use a similar ratio (NH HadCrut Series: 58% ocean, 42% land). But Frank Lansner wondered why, when he graphed the GISS land-data-set alongside the combined-sea-surface-temperatures (CSST), GISS comes up with an “averaged” line that runs much closer to the land data set and not the sea surface set. If it were weighted 60:40 (ocean:land) the combined Northern Hemisphere line ought to run slightly closer to the ocean based temperatures.
So Lansner mixed the land and sea temperatures in different ratios and graphed them and an odd thing occurred. Perhaps there is some good reason for it, but the GISS NH average line is currently running close to a mix that could be almost 70% land, and only 30% ocean. Back in 1985 the NH Average was closer to the sea temps as would be expected. In fact as late as 1995, the NH line still ran at around 40% land area. But […]
It’s taken 21 months, four professors, and three associate/assistant professors, and THIS is the best they could come up with? The printed version listed no author (the pdf has been updated with John Cooks name*) yet wears the logo of the University of Western Australia (UWA), which will embarrass that university as word spreads of the intellectual weakness of their “Guide“.
Did UWA commission this piece of rather inept, qualitative “feel-good” science and clumsy reasoning? Stephan Lewandowsky invited John Cook to speak at UWA and “offer assistance“.
The booklet uses a mislabeled graph with a deceptive scale, won’t show the damning graphs it supposedly debunks, assumes positive feedback occurs despite the weight of empirical evidence against it (Douglass, Spencer, Lindzen), and repeats irrelevant information even though The Skeptics Handbook describes why rising sea levels and glaciers and ice sheets can’t possibly tell us what causes the warming. It misleadingly discusses a different fingerprint — one that isn’t the key point and isn’t disputed by skeptics. Cause and effect are mixed up, and naturally there are strawmen arguments to unnecessarily destroy for the spectacle of being seen to do something. To top it off, Cook still thinks a measurement is […]

"Scientific Guide" To The Skeptics Handbook
I’m elated. Last night outside the Watts Up lecture at UWA here in Perth there were people handing out a so-called “Scientific Guide” to the Skeptics Handbook. Let’s put this in perspective, I wrote the Handbook two years ago, and it’s taken this long for those-who-want-to-scare-us to put together a specific printed response. I’m an unbacked, solo pro bono writer, and they needed no less than 5 professors, 2 associate professors, and 21 months, and THIS is the best they can do?
I’m also chuffed. The infamous Professorial fellow Stephan Lewandowsky spoke the night before in the same room as we spoke in (about the dangers of consensus) but maybe he’s finally read my multiple responses to the stone age reasoning he was using and the light bulb has gone off. Maybe he’s realized that the masses of engineers, geologists, lawyers, medical experts and people with just plain common sense out there are never going to be fooled by his old witchdoctor routine about the Gods of Science at the IPCC. I was informed by people who saw the presentation that for the first time he spoke without resorting […]
John Cook might be skeptical about skeptics, but when it comes to government funded committee reports, not so much.
The author of āskeptical scienceā has finally decided to try to point out things he thinks are flaws in The Skeptics Handbook. Instead, he misquotes me, shies away from actually displaying the damning graphs I use, gets a bit confused about the difference between a law and a measurement, unwittingly disagrees with his own heroes, and misunderstands the climate models he bases his faith on. Not so āskepticalā eh John? Heās put together a page of half-truths and sloppy errors and only took 21 months to do it. Watch how I use direct quotes from him, the same references, and the same graphs, and trump each point he tries to make. His unskeptical faith in a theory means he accepts some bizarre caveats while trying to whitewash the empirical findings.
In the end, John Cook trusts the scientists who collect grants funded by the fear-of-a-crisis and who want more of his money, but he’s skeptical of unfunded scientists who ask him to look at the evidence and tell him to keep his own cash.
These two graphs are not the same […]
The debate with Paleoclimatologist Dr Andrew Glikson about the evidence for Climate change has reached a telling point. There is a gaping hole.
Through four rounds of to and fro, Iāve been asking for evidence that the predicted (critical) āhot spotā was there above the equator, and we were drilling down to this point. Itās the weak link in the chain of evidence, and if the climate models are wrong on this element, you can kiss goodbye to the catastrophe. Everything else might be right, but thereās no major warming if thereās no strong amplifying (positive) feedback, and and there is no amplifying feedback from water vapor if there is no hot spot. Indeed, I quoted evidence from three peer reviewed studies that show that weāre headed for a half a measly degree of warming rather than a baking 3 ā 6 degrees.
In Round 2 Glikson didnāt mention Lindzen, Spencer or Douglass (the three independent papers which suggest that predicted feedbacks are missing or negative). Instead he suggested āSherwood 2008ā found the hot-spot. I pointed out that Sherwood used wind-gauges instead of thermometers. To believe he is right we need to throw out thousands of thermometer readings and […]
UPDATED Part IV: Andrew Glikson replies below.
I am impressed that Glikson replied politely, rose above any ad hominem or authority based arguments, and focused on the science and the evidence. This kind of exchange is exceedingly rare, and it made it well worth continuing. Links to Part I and II are at the end. Round 4 was copied from comments up to the post.
Depending on flawed models
by Joanne Nova
May 11, 2010
For a sentence, I almost think Dr Glikson gets it. Yes, itās a quantitative question: Will we warm by half a measly degree or 3.5 degrees? Itās not about the direct CO2 effect (all of one paltry degree by itself), itās the feedbacksāthe humidity, clouds, lapse rates and other factors that amplify (or not) the initial minor effect of carbon.
Decades ago, the catastrophe-crowd made guesses about the feedbacksābut they were wrong. Instead of amplifying carbonās effect two-fold (or more!) the feedbacks dampen it.
Dr Glikson has no reply. He makes no comment at all about Lindzen [1], Spencer[2] or Douglass[3] and their three peer reviewed, independent, empirical papers showing that the climate models are exaggerating the warming by […]
Dr Andrew Glikson (an Earth and paleoclimate scientist, at the Australian National University) contacted Quadrant offering to write about the evidence for man-made global warming. Quadrant approached me asking for my response. Dr Glikson replied to my reply, and I replied again to him (copied below). No money exchanged hands, but Dr Glikson is, I presume, writing in an employed capacity, while I write pro bono. Why is it that the unpaid self taught commentator needs to point out the evidence he doesn’t seem to be aware of? Why does a PhD need to be reminded of basic scientific principles (like, don’t argue from authority). Such is the vacuum of funding for other theories that a debate that ought to happen inside the university obviously hasn’t occurred. Such is the decrepit, anaemic state of university science that even a doctorate doesn’t guarantee a scientist can reason. Where is the rigor in the training, and the discipline in the analysis?
Credibility lies on evidence

Reply to Andrew Glikson
Dr Andrew Glikson still misses the point, and backs his arguments with weak evidence and logical errors. Instead of empirical evidence, often […]
This is the copy of the file I sent the ABC Drum Unleashed. I’m grateful they are allowing both sides of the story to get some airtime (though Bob Carter’s , and Marc Hendrickx’s posts were both rejected. Hat-tip to Louis and Marc). Unfortunately the updated version I sent late yesterday which included some empirical references near the end was not posted until 4.30pm EST. (NB: The Australian spelling of skeptic is “sceptic”)
Somehow the tables have turned. For all the smears of big money funding the ādeniersā, the numbers reveal that the sceptics are actually the true grassroots campaigners, while Greenpeace defends Wall St. How times have changed. Sceptics are fighting a billion dollar industry aligned with a trillion dollar trading scheme. Big Oilās supposed evil influence has been vastly outdone by Big Government, and even those taxpayer billions are trumped by Big-Banking.
The big-money side of this debate has fostered a myth that sceptics write what they write because they are funded by oil profits. They say, follow the money? So I did and itās chilling. Greens and environmentalists need to be aware each time they […]
UPDATED (see below)
Richard Lindzen is unarguably one of the top meteorologists in the world, with over 200 publications to his name, as well as awards, medals, prizes and is a member of the NAS, AAAS, AGU, AMS. He is The Alfred P. Sloan Professor of Atmospheric Sciences, Massachusetts Institute of Technology and his work includes major contributions to our understanding of the Hadley Circulation, small scale gravity waves on the mesosphere, as well as atmospheric tides and oscillations in the tropical stratosphere. From the beginning, he has questioned the claims that there is a crisis due to carbon dioxide emissions, pointing out that even with the poor resolution of ice cores back in the 1980’s it was still evident that there was a lagāas temperatures declined, carbon stayed high for thousands of years, something which didn’t sit well with the idea that carbon had a strong and constant force on the climate.
What follows are his thoughts on the current state of the science. They must make it awkward for those who can’t help themselves but believe in authority. Here’s a man who knows more than most of us could ever hope […]
DeSmogBlog could’ve flattened The Skeptics Handbook in just one sentence.
All they had to do was point to empirical evidence that more CO2 forces temperatures up. They can’t and everything else is bluster and bluff.
The question of evidence is on the front page; the book is built around it, and billions of dollars hinges upon it, on this topic, “nothing else matters…”. Yet Jeremy Jacquot’s sole attempt at evidence only shows he doesn’t know what evidence is. Even a bright junior high spark could prove him wrong with a 20 year old encyclopedia. Jacquot uses 3000 words to NOT answer that question, he confuses himself, resorts to cut-n-pasting from the site that does his thinking for him, and makes at least 9 errors of logic and reason. Jacquot complains that I’ve rehashed and repeated old arguments, which only makes it all the more embarrassing that he still hasn’t got any good answers.
But the part I like best was the way he jumps through the hoops just as I predicted. The Skeptics Handbook says when you poke a believer they will bark ‘Santer’, ‘Sherwood’, and ‘amplification’ and he does, right on cue. Yap Yap Yap. DeSmogBlog […]
Big names like Santer, Sherwood, and Schmidt admit that the models predict more warming 10 km above the equator than what the weather balloons could find. Each time they announce that they’ve resolved the differences, they have to start by admitting there are differences to resolve. […]
This is vintage spinmeister-Tim. Overall he claims I’m deluded, confused, constantly repeating discredited arguments, “doesn’t even know what the hot-spot is”, and “doesn’t understand how the greenhouses gases warm the planet”. But when it comes to backing up the giant patronizing put-downs, it amounts to nit-picking phraseology; irrelevant points; straw men; his own false understanding of what a fingerprint is; and then an own goal when he drops in a graph that shows that the hot-spot is indeed missing.

The gap between real world data and thermometers is a make-or-break issue for the AGW theory. The models predict a hot-spot in the atmosphere above the tropics, but the weather balloons (called radiosondes) can’t find any sign of it. Most claims that the hot-spot has been found are not providing any new data, they are just massaging the same old numbers with a different statistical tool. Here are three variations (though the third is not a statistical-spin, it’s just nonsense).
1–Some AGW supporters claim that Santer et al has found the hot-spot. But his paper boils downs to a statistical reanalysis that suggests that due to noise and error, the hot-spot might be there. Santer hasn’t actually found the missing hot spot. He has a case, but it’s not a strong one. The statistical counterargument is at Climate Audit.

The ‘Hotspot’ is crucial to the climate debate.
If greenhouses gases are warming the planet that warming will happen first in the cold blob of air 8-12 km above the tropics. It’s freezing cold up there, but it ought to be slightly less freezing cold thanks to greenhouse gases. All 20-odd climate models predict warming there firstāit’s the fingerprint of greenhouse gas warming, as opposed to warming by some other cause, like solar magnetic effects, volcanic eruptions, solar irradiance, or ozone depletion etc etc.
Look at A above, the greenhouse gas fingerprint is markedly different from the rest and dominates the overall predicted pattern in graph F. The big problem for the believers of AGW is that years of radiosonde measurements can’t find any warming, as shown in part E of Figure 5.7 in section 5.5 on page 116 of the US CCSP 2006 report
