John Kerry: Fraudulent Letters Advocate Delay

Well, we are used to anonymous people showing up in random comment threads who clearly know nothing about science that they didn’t read in mass media who feel comfortable proclaiming themselves to be professors. It’s practically an epidemic. You have to wonder what they think they are achieving by misrepresenting themselves.

Oh, if I really *were* a scientist I *still* wouldn’t believe this stuff, so I might as well pretend to be one…“?

But this is a new one. According to Senator John Kerry, via the Charlottesville (VA) Daily Progress:

[a] congressman’s office received at least six letters from two Charlottesville-based minority organizations voicing opposition to the measure.

The letters, as it turns out, were forgeries.

“They stole our name. They stole our logo. They created a position title and made up the name of someone to fill it. They forged a letter and sent it to our congressman without our authorization,” said Tim Freilich, who sits on the executive committee of Creciendo Juntos, a nonprofit network that tackles issues related to Charlottesville’s Hispanic community. “It’s this type of activity that undermines Americans’ faith in democracy.”

The faked letter from Creciendo Juntos was signed by “Marisse K. Acevado, Asst Member Coordinator,” an identity and position at Creciendo Juntos that do not exist.

The person who sent the letter has not been identified, but he or she was employed by a Washington lobbying firm

OK, really? What’s the ethical argument here? “If I really *were* Hispanic I would still oppose Waxman, so it’s OK to steal organizational letterhead and write to a congressman claiming to represent them“???

This isn’t just a kid trolling the comment threads on the internet for earnest liberals to bother. This is a professional organization performing its duties to its client as they perceive them deliberately injecting noise into the governing process.

What do these people think they are achieving? How the hell do they sleep at night?

Is this for real? Here’s a climate story for the mainstream media. Rake some muck, please.

Denialist Backlash vs Rudy Baum

Much as I hate to link to Morano, and much as I hate participating in the “news cycle”, here’s another denialist tactic that demands a quick response.

Rudy Baum has published a perfectly sound editorial in Chemical and Engineering News. Most notably:

On June 11, the presidents of the G8+5 national academies of science released a joint statement, “Climate Change and the Transformation of Energy Technologies for a Low Carbon Future PDF icon,” which states: “Climate change and sustainable energy supply are crucial challenges for the future of humanity. It is essential that world leaders agree on emission reductions needed to combat negative consequences of anthropogenic climate change.” The G8+5 consists of Canada, Italy, the U.K., the U.S., Japan, France, Germany, and Russia (G8), and Brazil, India, South Africa, China, and Mexico (+5).

Leaving aside the tragic extent to which the press ignores these G8+5 national academy pronouncements, Baum proceeds to describe the tactics of the deniers (he calls them “CCDs” for “Climate Change Deniers”) about as effectively as a few paragraphs’ space allows:

We see here the same tactics used by other purveyors of nonsense rejected by the mainstream scientific community. Creationists, for example, only want to expose students to “both sides of the debate over origins,” ignoring the fact that there is no debate over evolution. And, of course, it’s always useful to attack the “mainstream media.”

Heartland and its ally are also flogging an 800-plus-page report, “Climate Change Reconsidered PDF icon,” from the Nongovernmental International Panel on Climate Change (NIPCC)—kind of an anti-IPCC, get it?—which, of course, proves conclusively that global warming probably isn’t happening; if it is happening, it’s not due to human activity; and, besides, a “warmer world will be a safer and healthier world for humans and wildlife alike.”

Sow doubt, make up statistics, call for an “open debate,” claim that you are being “silenced and ignored by the media and politicians,” claim that your opponents are just a “few bureaucrats and environmental activists,” not real scientists—those are the tactics that will be brought to bear in the coming months by the CCDs in their attempt to derail meaningful efforts to respond to global climate change.

Nothing here new, right? Well maybe not to the likes of us, but this is new stuff to C&E News, apparently, and a denialist drumbeat has been raised. If you can stand it, look at Morano’s article.

Then have a look at the current letters section.

We see the usual stuff. People who are not actually aware of the denialists tactics, who believe that the stuff of legitimate scientific discourse is in a very diferent place than it actually is, and even some very confused nonsense that probably shouldn’t have passed editorial muster for a science magazine like this:

I’m a geologist, not a chemist, but I must say that I expected better from this science magazine.

The article cites a panel that says drastic cuts are in CO2 emissions are needed to prevent acidification of oceans by 2050. It further asserts that computer models suggest that coral reefs and polar ecosystems will be seriously harmed by 2050 if CO2 emissions are not seriously curtailed.

Are these the same or similar models that have not been able to correctly account for any well-documented historical variations in global temperature such as the Medieval Warm Period and the Little Ice Age? Isn’t it possible (or rather, likely based on scientific evidence) that CO2 is not the driver of global warming but the result of naturally occurring warming? Certainly chemists should know that as the oceans warm, they are able to hold less CO2 and will thus release increasing quantities of CO2 from solution into the atmosphere, rather than absorbing CO2 and becoming more acidic?

More at issue is the lead letter, that equates Mr. Baum’s quite precise description of the circumstances at hand with “left-wing opinions”.

To say this is unfortunate is an understatement. I call it the fallacy of the center: that the truth must lie somewhere between the arguments that you hear. This phenomenon can be easily gamed by a side with no respect for truth: to tell lies so extreme that by comparison the distance between the actual truth and the opposite extreme becomes relatively tiny. Then the reasonable if inattentive person will split the difference, and perceive any exposition of actual truth as biased, since it is relatively near one pole of the debate.

The careful reader should first refer to the opinions of the relevant scientific bodies, secondly to the alleged tactics of the deniers, and try to establish some ways to test the competing social hypotheses: 1) All 13 major scientific powers’ national science academies are unanimously lying, perhaps to protect their few dozen climatologists who are lying because they have sinister friends in the renewable power industry or 2) A few groups are lying perhaps because they have sinister friends in the fossil fuel industry (who may perhaps be a small fraction of that community) the value of whose reserves are threatened.

One (or both) of these, unfortunately, must be true.

If you don’t have the time or skill to evaluate the evidence directly you should ask which hypothetically lying group has potentially more at stake, which hypothetically lying group has the access to the resources and skills to construct a convincing fabric of lies, which hypothetically lying group has the least to lose from defections, and which hypothetically lying group has a more socially irresponsible history.

As someone sufficiently involved in the material to be able to distinguish cogent argument from incoherent blithering, I vouch for the scientific evidence lining up with the more plausible hypothesis.

In short, Rudy Baum has got it exactly right and it would be good to figure out what we can do as a community to help him.

Update: Eli predicted this kerfluffle and has a few more observations, as well as a mailing address for letters of support. It is fair to take note that the letters in C+EN were not unanimous, despite Morano’s portrayal of them.

Update: Morano oddly devotes a lot of attention to somebody (somebody he calls a scientist, but then again, he calls me a professor) who apparently wrote Baum this elegantly reasoned and finely honed argument: “When all is said and done, and you and your kind are proven wrong (again), you will have moved on to be an unthinking urn for another rat pleading catastrophe. You will be removed. I promise.” It’s mysterious to me why Morano decided to highlight this person and his peculiar rat-urn argument.

Update: Baum replies to the letter-writers, including rat-urn-dude here.

End Times Thinking and the Locavore Fallacy

I am not confident that the world will muster the foresight needed to thrive indefinitely. I do suspect that the economies of the west have peaked. I also think that the economy of the world will peak soon. This makes me a pessimist compared with the mass media, the government, the business community.

But compared with garden variety pessimists I am a wild-eyed optimist. I don’t think we are anywhere near running out of food.

In the comments to a very doom-laden article on the Oil Drum by Peter Goodchild, Euan Mearns comments:

I gather that we use about 5% of our energy in agriculture, and on that basis I don’t see that agricultural output will be immediately threatened by energy decline since I assume we will manage some how to prioritise. Furthermore, with conversion ratios of 7 to 10:1 for meat, we have a substantial buffer there where high meat prices may encourage us to eat more plant produce.

This seems right to me. The world is a long way from starvation.

If transportation becomes an order of magnitude more expensive, we will see no more of South American or New Zealand fruit, but continent-wide exchanges of food remain affordable. I think it costs about a penny to ship a tomato across the continent. If that goes up to a dime, we will still have out-of-state tomatoes.

What he learned from Katrina is that our customs make it impossible to abandon a city; we are tied to our “real estate” now as much as it freed us in the past two decades. New Orleans limps back to life whether people want it to or not. New Orleans has no choice. So as I look at the bizarre Texas drought and do what we all do nowadays when weather gets strange (wonder whether it is permanent) I contemplate the vision of a heavily populated Texas as dry as California, but perhaps lacking the power to appropriate water for far afield.

My more apocalyptic local friends are all talking about local gardens, because it will be too expensive to ship food. Maybe it will come to that someday, but not for a long time. Meanwhile, which is more expensive (more energy intensive) to ship to Texas: a tomato, or enough water to grow a tomato?

Fruits and vegetables are high value cargo. Water and fertilizer (and coal and timber and rocks and cement and steel) are not. If transportation becomes expensive, it is the low value industrial processes that relocalize. In wetter areas, bulk foods like grains may relocalize as well, though many grains ship well by sea, where shipment costs are negligible.

But the more I think about it, the more I think the locavore movement, whatever its social benefits, is fighting an uphill battle. Increasing shipment costs actually pull for efficiency of production, especially good soil and sustainable water. What little farming there is in Texas will decline sharply if this summer is a taste of the future. The huge population will decline only slowly. Food will be imported, and we will find a way to pay for it somehow.

On the other hand, increasing energy costs (and further increases in population, along with continuing decline in fish stocks) argue for less meat in the diet, as does direct greenhouse forcing via ruminant belching. And the terrifying message of the movie Food Inc. that I saw recently has me convinced that corporate meat sources are unethical. Local high value-add production of meat and of processed foods, on the model of traditional food production in Europe, is a good way to make use of human efforts and natural resources while respecting animal life. And in general, fresh, of course, is better.

But this romantic idea of making reliance on local resources on an overcrowded planet into an intrinsic goal is a fetish and a wrongheaded idea except in very remote places.

(On the other hand, I am glad I am not a citizen or landowner in Australia. I don’t see how they cope given present trends of energy and climate.)

Hope for Texas: Moderate to Large El Nino

Speaking of El Nino, the forecast is definitely for a moderate event at least this winter. Some groups are calling for a large event.

This is great news for us here in south-central Texas, and where drought conditions are currently extreme. It’s been six weeks of remarkably hot and dry weather even by local standards. It amazes me that so many plants are still looking healthy. Soil moisture is so close to zero as not to make a difference.

Fortunately, El Nino (negative SOI) correlates positively with precipitation. Unfortunately, there’s several months ahead before we collect on this promise.

I wonder, though, what a strong El Nino event might do for public perceptions of climate change. We might be due for some strange episodes. I have some pretty clear memories of the great Montreal ice storm in the 1998 El Nino.

We’ve been trained to say that “no individual event can be attributed directly to climate change”, and talk about loaded dice, etc. The next really big El Nino we will put us in uncharted territory, though. I wonder if the campaign to get El Nino language into the climate debate territory isn’t partly just an effort to deflect the attention to climate change that whatever weirdness we see in the next year might bring.

Even so, speaking as a Texan, (and I may live to regret this) if you’ve got some El Nino handy, bring it on down to my place, honey! It can’t be much worse than what we’ve got already.

A Litmus Test for the Naysayers

The denial group is behaving in a very revealing way.

The denialists are now trumpeting a very silly argument that El Nino (a quasiperiodic oscillation with energy in the 2-10 year band) is dominating secular trends in global temperature by an argument that I summarized in seven steps recently.

I would like to start the day with a shorter summary:

1) El Nino dominates interannual variability.
2) Frantic armwaving, accompanied by sciencey-looking charts and graphs.
3) Therefore, warming is predominantly due to El Nino.
4) Therefore, very not the IPCC.

Of course conclusion 4 will resonate with the Not the IPCC crowd. It is the conclusion they want, er, I mean, the conclusion that their serious thought has led them to in the past, right?

The trouble is, their argument goes like this

1) The sun is the source of atmospheric energy
2) Frantic armwaving, accompanied by sciencey-looking charts and graphs.
3) Therefore, warming is predominantly due to solar changes.
4) Therefore, very not the IPCC.

Admittedly, there is some similarity in the discourse. But notice, notice carefully, the subtle difference. These are based on altogether different premises and reach (in step 3) contradictory conclusions. They cannot both be true!

Let’s stipulate for the sake of argument that either or both of these were scientific hypotheses and not political gamesmanship. Then, whoops, while they reach identical political conclusions, they are competing scientific hypotheses. Therefore the scientists, having two competing hypotheses, will immediately set out to find evidence in support of their view and in opposition to the other.

On the other hand, if both groups are simply seeking ways to reach conclusion 4, they will consider themselves compatible and issue mutual congratulations. So have a look at the usual “skeptic” sources and see whether this new information is

A) dismissed as nonsense
B) thoughtfully treated as a significant challenge to their world view
C) celebrated without much regard for intellectual coherence

Only responses A or B are consistent with scientific thought. For instance, as I write I haven’t looked at Watts Up yet, but I am guessing C.

Hmm, my prognostic abilities are validated!

The Not the IPCC crowd is making a mistake by lining up behind this McLean nonsense. In doing so they demonstrate that they have no scientific hypothesis.

People on record with a solar-centric view who immediately celebrate this result demonstrate that whatever thought they have put into this problem has no scientific component. They simply have a political view that the IPCC must be wrong and will promote anything that sheds doubt on the consensus view.
That’s politics, not science. Which is what we’ve been saying about them all along.

If She Weighs the Same as a Duck, She’s Made of Wood

Update 7/28/09: This rather long exposition was written on my first exposure to the paper. One doesn’t know what to expect, and of course tries to keep an open mind to new ideas especially after they have passed peer review. I have gotten a fair amount of attention from this but in retrospect I find it a bit balky, and wished I had made the point more succinctly.

Both my point (focusing on the tortured logic) and Tamino’s (focusing on an obvious and demonstrable weakness of the tortured logic) are made very effectively in a brief comment on the RealClimate article by Ron Taylor which I quote here in its entirety. For most purposes this is all you really need to know about the new paper, Influence of the Southern Oscillation on tropospheric temperature, (McLean, de Freitas and Carter).

I have been reading and rereading this post and the comments, but still find the whole thing strangely puzzling. It seems to me that any good first year calculus student should be able to quickly find the fatal flaw in the methodology as a way of explaining temperature change (as opposed to temperature variability, since it discards any secular component). So I thought they were being really clever by making a valid correlation of SOI with temperature variability, then subtly changing the language to temperature variation. Many people, including journalists, would conflate temperature variation and temperature change, with no further effort required on the part of the authors. It looked like an example of: “If you can’t convince them with facts, then dazzle them with footwork.”

But then they claim in the press release that it actually explains temperature change, and they do so with no apparent embarrassment. Unless I am really missing something it seems incomprehensible that anyone in the scientific community would take this paper seriously.

Original posting begins:

The denialists are making a big deal about the new paper, Influence of the Southern Oscillation on tropospheric temperature, (McLean, de Freitas and Carter).

It’s a data analysis paper, and pretty much a no-brainer. It shows that global mean temperature variance is dominated by the El Nino/Southern Oscillation index (which most climatologists would have said was obvious) and that the lag is about 7 months, with ENSO leading the temperature (a modestly useful result).

The odd bit is toward the end:

[33] Chapter 3 of the Working Group I contribution to the Fourth Assessment Report by the Intergovernmental Panel on Climate Change (IPCC) [2007] notes the strong relationship between the ENSO and various climate phenomena, including surface temperature. Chapter 8 reports “considerable model skill out to 12 months for ENSO prediction.” Chapter 9 raises the question of ENSO response to continued anthropogenic warming, although causal connections are not clear. However, nowhere does IPCC [2007] mention the delay between a change in ENSO and a corresponding change in GTTA, which we have shown here to be 7 months. Climate modelers acknowledge that their models do not adequately hindcast average global temperatures from 1950 to 1990 and apply a human influence factor to make up the deficit. The strength of the time lagged relationship between ENSO and GTTA, as demonstrated here, suggests that variation in the poorly modeled ENSO may account for the deficit and may be the cause of a large part of the observed warming since the midtwentieth century. The sequence of the lagged relationship indicates that ENSO is driving temperature rather than the reverse. Reliable ENSO prediction is possible only to about 12 months [IPCC, 2007], which implies that accurate temperature forecasting beyond that period will only be possible after improvements in ENSO prediction.

[36] Since the mid-1990s, little volcanic activity has been observed in the tropics and global average temperatures have risen and fallen in close accord with the SOI of 7 months earlier. Finally, this study has shown that natural climate forcing associated with ENSO is a major contributor to variability and perhaps recent trends in global temperature, a relationship that is not included in current global climate models.

This builds loosely on

[29] The Great Pacific Climate Shift of 1976 [Guilderson and Schrag, 1998] appears to have had an effect on the SOI and therefore on the GTTA. The abruptness of this change suggests a major physical event, but no definite cause has been established. McPhaden and Zhang [2002] report a significant decrease in the estimated cold-water upwelling since that time. This implies a warmer Pacific Ocean and a bias toward El Niño events, but it is unclear whether this is a cause or consequence of the shift. Figure 4 shows that the change in SOI, in February or March of 1976, was followed by a corresponding change in GTTA in the last few months of the year. The granularity of the RATPAC-A GTTA data prevents clear identification of the time of change but it appears to be consistent with the time lag reported here.

[30] For the 30 years prior to the 1976 shift (i.e., 1946–1975) the SOI averaged +1.93 but in the 30 years after 1976 (i.e., 1977–2006) the average was −3.06, which represents a shift from a La Niña inclination to an El Niño inclination. The standard deviations for the two periods were 9.48 and 10.40 on monthly SOI averages, and 6.56 and 6.35 on calendar year averages, which indicates consistent variation about a new average value. Only the RATPAC-A data are available for lower tropospheric temperatures both before and after this shift, and even then we are limited to 17-year periods for our analysis of RATPAC-A data because monitoring did not commence until mid-1958. From 1959 to 1975 the RATPAC LTT averaged −0.191°C and from 1977 to 1993 it averaged +0.122°C. The standard deviations on the seasonal data were 0.193° and 0.163 C°, and on monthly data 0.162°C and 0.146°C. We have already illustrated the close relationship between SOI and GTTA, but this description of the respective changes before and after the Great Pacific Climate Shift indicates a stepwise shift in the base values of each factor but otherwise relatively consistent ranges of variation.

[31] The findings presented here are consistent with the Southern Oscillation being a major driver of temperature anomalies, not only in the tropics but also on a global scale. In passing we also note that according to the relationship between SOI and GTTA, 1983–1984 would likely have been about as warm as 1998 if not for the cooling influence of El Chichón.

Now we see the authors making claims like this in informal venues:

“The surge in global temperatures since 1977 can be attributed to a 1976 climate shift in the Pacific Ocean that made warming El Niño conditions more likely than they were over the previous 30 years and cooling La Niña conditions less likely” says corresponding author de Freitas.

“We have shown that internal global climate-system variability accounts for at least 80% of the observed global climate variation over the past half-century. It may even be more if the period of influence of major volcanoes can be more clearly identified and the corresponding data excluded from the analysis.”

Bob Carter, one of four scientists who has recently questioned the justification for the proposed Australian emissions trading scheme, says that this paper has significant consequences for public climate policy.


“The close relationship between ENSO and global temperature, as described in the paper, leaves little room for any warming driven by human carbon dioxide emissions. The available data indicate that future global temperatures will continue to change primarily in response to ENSO cycling, volcanic activity and solar changes.”

“Our paper confirms what many scientists already know: which is that no scientific justification exists for emissions regulation, and that, irrespective of the severity of the cuts proposed, ETS (emission trading scheme) will exert no measurable effect on future climate.”


“When climate models failed to retrospectively produce the temperatures since 1950 the modellers added some estimated influences of carbon dioxide to make up the shortfall,” says McLean.

“The IPCC acknowledges in its 4th Assessment Report that ENSO conditions cannot be predicted more than about 12 months ahead, so the output of climate models that could not predict ENSO conditions were being compared to temperatures during a period that was dominated by those influences. It’s no wonder that model outputs have been so inaccurate, and it is clear that future modelling must incorporate the ENSO effect if it is to be meaningful.”

So was the purpose of the paper to extract a useful correlation (7 month lag)? Or was it to construct a polemic? Did the reviewers not catch the little propaganda digs at the end? Are those digs justified by the paper? What about the broad conclusions being quoted in the denyosphere?

Here’s how the argument goes as I see it:

  1. We identify the lag between ENSO index and temperature, and reassert the obvious fact that ENSO accounts for most of the variance in the global temperature record
  2. We point in the direction of an abrupt shift in Pacific temperatures in 1976, and assert that this correlates with a shift in the ENSO index, and that the causality is not well known.
  3. We acknowledge that IPCC has always said the obvious fact that ENSO dominates temperature variance, and make a few random apple pie statements about ENSO predictability
  4. Glommed onto the above paragraph we assert that CO2 sensitivity has been used as a fudge to account for unforced climate models failing to reproduce the temperature signal! (“Climate modelers acknowledge that their models do not adequately hindcast average global temperatures from 1950 to 1990 and apply a human influence factor to make up the deficit.”) ??
  5. ENSO leads global temperature on a seasonal time scale, therefore this “suggests that variation in the poorly modeled ENSO may account for the deficit and may be the cause of a large part of the observed warming”! ??
  6. Accurate temperature forecasting beyond ENSO predictability horizon is impossible (well, on ENSO time scales, obviously… or…?)
  7. If ENSO forces temperatures and GCMs can’t predict ENSO, therefore GCMs can’t predict temperature. “natural climate forcing associated with ENSO is a major contributor to variability and perhaps recent trends in global temperature, a relationship that is not included in current global climate models” ? “perhaps trends” ?

Note that 6 and maybe 7 are reasonable statements in the context of ENSO predictability but not in the context of policy time scales. These are at the ends of the paragraphs and might well pass the eye of the ENSO-centric reviewer.

Points 4 and 5 though are pretty much meaningless in the ENSO context, but are huge whoppers in the context of policy time scales. Points 4-7 can easily be read as if they were a coherent counter-theory of global warming, and in retrospect were obviously intended to be so read. But points 4 and 5 are sort of buried where the hassled ENSO expert might glaze right over them.

I suggest that points 4 and 5 should not have passed peer review. The reviewers, unfamiliar with the deniosphere or the pseudocontroversy can be forgiven for missing the double meanings of points 6 and 7. And who expects a little piece like this of ulterior motives?

But points 4,5,6,7 can be strung together to make a case that the modest evidence presented in the paper doesn’t remotely support. The actual result is really not involved at all save as camouflage for this “disproving” of “global warming”. Have I missed something?

(Update: yes, I missed something, but it wasn’t in the article’s favor! The data are bandpassed and the trend is totally erased in preprocessing! Tamino)
We are going to be stuck with this stinker for a while. This is new and different; it seems the authors were aiming to score propaganda points as much as to publish a modest result. If I read that right it’s very unfortunate. I hope this sticks to the reviewers, but of course it won’t. There are no consequences for bad reviewing. That’s a core principle of science journals. Otherwise the free labor would go away.

Update: Kiwi press coverage: “Climate Change Down to Nature

Update: See also this follow-up. I argue that the denialists are making a mistake by latching on to this publication.

Update: Drudge points to the Washington Examiner on the story. Still no major media coverage, which I think is appropriate.
Update: Thanks to RealClimate for linking here. Please don’t miss Tamino’s article pointing out that the McLean paper can’t possibly have anything to say about trends since the trends are removed in the processing.
Update: What is going on is a bit subtle, and this was written in haste, so it;s little wonder a lot of folks are missing the point.

The paper identifies the correlation lag between a bandpassed correlation of ENSO index and global mean tropospheric temperature. The methodology is dubious but that us secondary. The reason this is news is that they try to connect this result with a global warming trend.

Tamino offers a proof that the connection is meaningless.

My contribution was to attempy to explain how the design of the paper is cynical. I see that it is not going to be easy to explain this very well.

The ordinary result about El Nino is merely a vehicle. The payload is a bunch of unjustified conclusions toward the end, which are written in such a way as to resemble the usual bread and butter commentary of the El Nino community with a bit of modest speculation thrown in. The reviewers only let this pass because they did not notice the possibility of drawing on this to make controversial conclusions.

It’s science by double entendre.

The trick being undertaken here is subtle, and explicitly draws upon the gap between the scientific community and the rest of the world, and specifically on the obsessions of the El Nino prediction community.

It doesn’t look accidental to me. I see it as a successful attempt to slip something past the reviewers. Compare the modest claims of the abstract (which the reviewers would be thinking about) with the concluding paragraphs.

The abstract concludes:

“That mean global tropospheric temperature has for the last 50 years fallen and risen in close accord with the SOI of 5–7 months earlier shows the potential of natural forcing mechanisms to account for most of the temperature variation.”

which is what any physical climatologist would have expected with or without the present paper. In other words “this is normal science, nothing controversial here, these are not the droids you are looking for”.

The claim in the abstract has nothing whatsoever to do with the global warming trend, but only with the interannual variance.

Only a little bit of sloppy speculation in the paper even leans in the direction of talking about the trends. (Tamino’s analysis shows how unjustified that speculation is). What I’m trying to say is that the paper was presented in such a way as not to emphasize that sloppy speculation at all, until it got published, when it was suddenly all over the press.

This is not just a lousy paper. It’s something much worse. It’s cleverly manipulative.
