Debunking a Climate-Change Skeptic 807
DJRumpy writes "The Danish political scientist Bjørn Lomborg won fame and fans by arguing that many of the alarms sounded by environmental activists and scientists — that species are going extinct at a dangerous rate, that forests are disappearing, that climate change could be catastrophic — are bogus. A big reason Lomborg was taken seriously is that both of his books, The Skeptical Environmentalist (in 2001) and Cool It (in 2007), have extensive references, giving a seemingly authoritative source for every one of his controversial assertions. So in a display of altruistic masochism that we should all be grateful for (just as we're grateful that some people are willing to be dairy farmers), author Howard Friel has checked every single citation in Cool It. The result is The Lomborg Deception, which is being published by Yale University Press next month. It reveals that Lomborg's work is 'a mirage,' writes biologist Thomas Lovejoy in the foreword. '[I]t is a house of cards. Friel has used real scholarship to reveal the flimsy nature' of Lomborg's work."

Hi Keith,
Okay, today. Promise! Now something to ask from you. Actually somewhat important too. I
got a paper to review (submitted to the Journal of Agricultural, Biological, and
Environmental Sciences), written by a Korean guy and someone from Berkeley, that claims
that the method of reconstruction that we use in dendroclimatology (reverse regression)
is wrong, biased, lousy, horrible, etc. They use your Tornetrask recon as the main
whipping boy. I have a file that you gave me in 1993 that comes from your 1992 paper.
Below is part of that file. Is this the right one? Also, is it possible to resurrect the
column headings? I would like to play with it in an effort to refute their claims.
If published as is, this paper could really do some damage. It is also an ugly paper to
review because it is rather mathematical, with a lot of Box-Jenkins stuff in it. It
won't be easy to dismiss out of hand as the math appears to be correct theoretically,
but it suffers from the classic problem of pointing out theoretical deficiencies,
without showing that their improved inverse regression method is actually better in a
practical sense. So they do lots of monte carlo stuff that shows the superiority of
their method and the deficiencies of our way of doing things, but NEVER actually show
how their method would change the Tornetrask reconstruction from what you produced.
Your assistance here is greatly appreciated. Otherwise, I will let Tornetrask sink into
the melting permafrost of northern Sweden (just kidding of course).

"Without reading both books, I can't take sides on the merits. But I will say some of the stuff in TFA sets off my alarms--like spending a footnote on a WHO report just to cite the population of Europe."
When doing math, statistical sources matter. But here we have something substantial to discuss. Is Lomborg dishonest in this case? Read along for the answer!
Friel: "But Lomborg's only source for these figures—a chart in the statistical annex of a 2004 World Health Organization report—contains
no data on human mortality due to excess heat or cold. In fact, the words "excess heat" and "excess cold" make no appearance in the WHO document; neither does the word "heat," and the word "cold" appears only once in a reference unrelated to death due to excess cold.
Lomborg's reference to the WHO document, which allegedly supports his claim that two hundred thousand people die each year in Europe from excess heat, reads in its entirety: "207,000, based on a simple average of the available cold and heat deaths per million, cautiously excluding London and using WHO’s estimate for Europe’s population of 878 million (WHO, 2004a:121).”
However, page 121 of the 2004 WHO report—The World Health Report 2004: Changing History— which is what this source references, lists no data on cold- and heatrelated deaths per million, or for cold- and heat-related deaths in any context.
Likewise, Lomborg's very next reference-to support his claim that 1.5 million Europeans die annually from excess cold - reads in its entirety: "1.48 million, estimated in the same way as total heat deaths."
Thus, Lomborg's references indicate that page 121 of the 2004 WHO report is the source of his estimates of annual heat- and cold-related deaths in Europe; however, this page in the WHO report lists no statistics for either cold- or heat-related deaths. Consequently, there is no apparent basis here or elsewhere in Cool It for Lomborg's claim that 1.5 million Europeans die annually from excess cold. [LD, p. 86, emphasis added]
Lomborg: "In fact, the text and first endnote in this section make it very clear where the figures are sourced from: “Based on the summary of the biggest European heat and cold study (Keatinge, et al., 2000, p. 672).” (p. 170).
In the UK edition of the book, there is even a figure with the numbers, with the further explanation: “estimated in the text, using Keatinge et al., 2000:672.” (p. 233, CIUK) Friel’s claim that I relied on a WHO document that does not support my case is astonishing and profoundly disingenuous.
I clearly used the WHO report solely to provide an estimate of Europe’s population (because WHO uses the standard geographical definition of Europe to the Ural Mountains).This is evident in the text that Friel himself quoted: “and using WHO’s estimate for Europe’s population of 878 million (WHO, 2004a:121).”
Finding this study on Google Scholar took me all of two seconds using the reference provided by Lomborg (in his book).

The quote is confirmed by Google Books:

In short, from this example, picked by you - not me, it plainly evident that is Friels honesty or literacy that should be in question, not Lomborgs. This is likely to be representative of the "debunking" in its entirety, going from what I have read of the rebuttal so far.

He's more pragmatic than skeptic (Score:5, Insightful)
I haven't read his books, but I live in Denmark so Lomborg gets quite a bit of press here, especially under the climate change conference in December. In interviews he's always come across as a pragmatist more than a skeptic.
He has two main arguments:
1) Think about the return on investment.
Let's say we can cool the earth one degree by spending a trillion dollars. Is it worth the investment? What do we really get out of it? How many other problems could have been fixed with that money?
2) The current approach to fighting climate change is wrong.
UN treaties and money aren't going to stop the developing world from using fossil fuels. The only surefire way to get off of coal is to develop something that is cheaper. Instead of giving money to developing countries to bribe them not to pollute, we should invest the money in new technology, so that in 10, 20, 30 years we can say "here, this is cheaper than coal and doesn't pollute".
I think both of his points are important to consider, though I don't agree with him completely. There are risks to his solution - what if our investments don't bear fruit, and coal is still the cheapest energy source in 30 years? What if climate change causes political destabilization so we don't have enough time to get finished?
I don't think anybody has a perfect solution, but I do think that Lomborg contributes positively to the debate.

If it were a mere one trillion dollars for the whole world, it'd really be a drop in the bucket and well worth the investment. Aside from the issue of ROI, one has to consider the externalities of not spending the trillion dollars. Look at the mostly current financial/economic crisis. How much do you think that cost countries? How much do you think will be the cost of long-term shifting weather patterns? I'd imagine it might trivially be a lot more than most people would care to stomach compared to doing something now.
Funny, but that's the main reason cap and trade is such a good idea. It causes developed countries to start polluting significantly less, raises the current costs of coal/oil/etc (inherently making long-term investments in other energy sources possibly viable), allows for the collected taxes to be pushed into new energy technology, and hopefully the result will be energy that effectively is cheaper than the coal/oil/etc's original price. Even if the whole energy technology step doesn't work to produce something cheaper than coal/oil/etc, the system will both have proven that you can still be a developed country using massively less amounts of coal/oil/etc per capita (meaning developed countries, mimicking developed countries, need not believe they'll tank for what might others seem a reckless course of action) and almost certainly have higher efficiency technology to export to other countries so they'll inherently use less coal/oil/etc (since the efficiency technology will have been created in a [mostly] market based system and should be generally economical sound anywhere).
We're going to see that anyways. China has already taken some pretty bold steps about securing oil supplies for its developing economy. That's a major reason for the great increase in the price of oil; that is, if China hadn't been securing and using those oil wells, other western powers would have for their still increasing oil consumption. You can only pump so much oil out of the ground at one time, and so at some point Americans and Chinese will no longer be able to simply expand through more oil extraction. At that point, increasing the efficiency of technology will be necessary. In the interim, both China and America's economy will suffer rather badly (the US needs ~2.5% economic growth yearly just to maintain itself and China needs something close to ~10%) as oil prices will skyrocket.
We need to be developing alternative energies and efficiency technology now and not wait until "the market" takes care of things. "The market" doesn't take into consideration that while it might work hypothetically in a perfect world given enough time, in the real world a drastic short-term change in supply or demand can result in the sort of political instability that results in a lot of "force" upon a lot of people.

This drives the global warming proponents totally mad. Most of them seem to be of the opinion that what they have to do is convince people that global warming is real, and caused by humans. Once that is done, people should be willing to accept whatever policies they say are necessary. No questioning of the costs or the utility, they've proven the problem and now whatever they say needs to happen should happen without further question.
So Lomborg has become one of their top enemies because he doesn't fundamentally disagree on the idea that the world is warming, just that it is worth while to try and solve when there are so many other problems to human life. For that, they hate him.
That is one of the things that makes me question motives in this whole thing.

That is to be expected. Normally, temperature starts to rise due to e.g. distance to the sun decreasing slightly, which leads to increased CO2 which enhances the effect of the warming, causing further CO2 to be released until a new balance is achieved (essentially that the energy absorbed from the sun equals the earths black-body radiation). CO2 increase with temperature because CO2 is less soluble in warm (sea)-water, and a number of other effects (Tundra melting is often mentioned as a big one, though I don't personally know.). Now, into this system we (the humans) release enough CO2 to increase the concentration by what, 30%? What do *you* think will happen?
That CO2 must warm the earth can also be concluded directly by looking at the absorbtion bands of CO2.

You deserve upmods. It seemingly cannot be stated enough, because the "skeptics" don't get it: of COURSE temperature leads CO2 levels. What would a sudden, pre-temperature rise of CO2 levels come from? There wasn't much coal burned in the ice ages.
When no CO2 is added to the system, it merely works as a feedback for temperature changes, magnifying them. Oceans get warmer, reducing their capacity to dissolve gases, releasing more CO2. Rotting vegetation trapped in ice melts, releases methane and CO2. Fortunately, the additional CO2 released from warming is not enough to cause more warming than what released it, so it doesn't run away, it stabilizes at a new, higher temperature.
But when CO2 is added to the system from outside (fossil fuels trapped in the earth for ages), it's not just a feedback. It's a forcing, something that drives temperature change.
So, that CO2 followed temperature rises during the end of the ice ages is not evidence against global warming. It's what you would expect to happen when there are no humans around to burn gigatons of coal, if current theories of carbon feedback are correct.

You have such a simple-minded view of the planetary climate...that is...unfortunately...wrong. Planetary temperatures are not correlated with (in the order you mention them) 1)short-term earth-solar distance, 2)CO2 increases, 3)solar absorbtion-black body radiation 'balance', 4)warming sea water CO2 solubility decrease (also bad chemistry as carbonate chemistry is far more complex than just 'CO2 solubility') or 5) tundra melting.
That CO2 must warm the earth can also be concluded directly by looking at the absorbtion bands of CO2. You could even calculate the approximate effect (though not the feedback loops) from this, the atmospheric and distribution of CO2 and from the distribution of the electromagnetic waves in the atmosphere.
Apparently you have never actually looked at the absorption bands for CO2. There is already more than sufficient CO2 in the atmosphere to absorb all of the IR radiation that is capable of being absorbed by CO2, within the first few hundred meters of the atmosphere above the surface. Once absorbed, the energy is not trapped but is immediately re-emitted. The wavelength of the reemitted thermal radiation is a probability distribution depending ONLY on temperature that can be predicted with Planck's law and it is NOT concentrated within the narrow CO2 absorption band so almost all of that re-emitted raditation is free to radiate out into space untouched any further by your nemesis CO2.
But of course, you knew all this. What pisses me off about all this that while the above is well-known science and has been for a long time, the economic aspects are far from clear to me.

Technically correct, they show a feedback from CO2, not a forcing, which is what you would expect.

As the earth warmed, CO2 was released from oceans and frozen vegetation, causing further warming.
Without the feedback from CO2, the Milankovitch cycles would only cause a very modest change in temperature - not nearly sufficient to cause the ice age/interglacial cycles we know.
Before humans, temperature was driving the change, and CO2 caused the feedback.

1) Let's imagine that you are working on the bleeding edge of science and you're investigating a question that no-one knows the answer to, like "why does Nt-acetylation of bulk proteins happen?". You do some clever research, and whaddya know, you come up with an interesting answer: "it's because acetylation can function as a degradation signal". That forces a need to revisit thinking on protein turnover, a larger topic, and may even mean that we need to think again about exactly how homeostasis works. So you write it all up and if you can get the paper past your clever colleagues who do peer review, you might get published in Science and you can be very proud of yourself. Look, it's happened here!
http://www.sciencemag.org/cgi/content/short/327/5968/966 [sciencemag.org]
2) Now, let's imagine that you investigate something a bit more fundamental to modern biological science. Say, the idea that DNA encodes genetic information about the shape of proteins. Let's say you invent a clever experiment and the findings are very striking -- they appear to show that DNA doesn't encode that information after all! Now for the thought experiment bit: do you think that the standards and scrutiny that will be applied to your claim will be higher or lower than in scenario 1, given that your results will require the setting aside / reinterpretation of an enormous mass of prior experimental results and accepted scientific theory. Why, that's right! Your results will be subjected to more careful scrutiny. They will have to be replicated, validated, tested etc etc every which way from Sunday, because the inherent balance of probabilities is that your results are wrong or artefactual or explicable within the current framework, and that the prior thinking was right. It's not *impossible* that the opposite holds true, but it *is* extremely unlikely.
People who seek to demonstrate that anthropogenic climate change is not happening are much closer to scenario 2 than scenario 1.

There you go again. Conflating "climate change" with whether man is the most likely cause. Its really rather rich. The prime highlight of the IPCCs AR3 was to "forget" the existence of climate change prior to the 19th century. Natural variation over the past thousand years was reduced to quiet gradual downtrend with an abrupt surge upward in the 1800s. In so doing they discarded thousands of studies and work of thousands who previously carefully documented periods of great warming and cooling throughout the history of man.
This can be seen clearly by comparing the IPCC-1990 report, which concisely shows the consensus of an old guard (now largely dead). A very warm, much warmer period during the middle ages (shown in read). The IPCC AR3 and AR4 replaced this with the blue curve. Shown a flat-changeless temperature history with a slight downtrend, suddenly accelerating upward. [wikipedia.org]
But their claim was bespectacled from the start by way of special pleading they had explained away each interruption in warming that occurred during the 20th century, but then after the report was published, yet another unexpected cooling period emerged.
Suddenly the meme switched from being about "Global Warming" to being "Climate Change". The focus shifted from temperatures to sea-levels and hurricanes. Yet this turned out to be an even more tenuous footing. Its already no longer considered reputable among intellectual circles to discuss such extravagances. Eventually the talking point was settled upon: weather is not climate. The recent cooling is just weather.
Indeed, weather is not climate. Climate is the expectation of weather--and so yes, it surely does matter when year after year goes by somewhat cooler than had been predicted by the IPCCs latest report.
Meanwhile, the very people who had steadfastly refused to deny climate-change are now labeled the climate change deniers. This stemmed from an Orwellian campaign to redefine terminology. Suddenly believing in climate-change meant believing in anthropogenic climate change. The language literally twisted to be an embodiment of the "one true belief"--no need for that pesky modifier anthropogenic, and all the better to co-opt what everyone knows: climate changes.
Several very cogent critiques of the AR3 temperature series have been published which eviscerated that graph as a product of flawed statistical methods and bad data. Yet a loud cadre continues to deny any problem exists, and banks on the lack of specialized knowledge among the public and other scientists to trade on their word alone.
And, no, we're saying that there is no contribution from Man. CO2 is a greenhouse gas, but its effect on temperature depends on poorly understood feedback effects. These effects are in part also responsible for the long history of natural temperature variation that the IPCC otherwise ignores. Ultimately, what it comes down to is this: The IPCC claims a temperature rise of 2C/century. To arrive at this number they assume almost all strong feedbacks are amplifying rather moderating the C02 driven warming. Why does this matter? Much of the impetus for "ACTION NOW!" stems from the notion of a climate tipping point, but if the feedback effects are more moderating than the IPCC claims, this is highly unlikely.

I see this argument frequently, but it ignores the simple reality that unlike in Europe and Asia, the American economy is based on a highly mobile workforce able to commute great distances by automobile. The middle class, in particular, is enabled by and enriched by the automobile and cheap gasoline--the wealthier can live in expensive neighborhoods close to work, and the poor live wherever they can while commuting as little as possible; but, the middle class often work in areas where they could either not afford nearby housing which caters to the more affluent, or where nearby housing caters to the poor.
That's not always the case, of course, but it often is and the middle class has thrived on the ability to live in cheaper yet comfortable neighborhoods further from job centers--i.e., living in the suburbs while commuting to the city, or living in the country and commuting to the burbs. There's also a greater mobility and variety of jobs available to the middle class thanks to cheap gas: where I live, many commute to Washington, D.C., many others to Richmond, and a few to Charlottesville--meaning the job markets of 2.5 major cities are effectively local. Tax gas at a high rate, and people will have less employment mobility, fewer competitive opportunities, and lower overall wages due to the lowered competition among employers in formerly-neighboring employment centers. Additionally, with permanently expensive gas making long commutes cost-prohibitive for the middle class, there would be a huge migration out of the burbs and into more urban areas--where are all the urban poor going to move when whole cities are gentrified almost overnight? Into deserted suburbs with few native local job opportunities?
Tax gas at a high rate, and the mobile workforce and all the competitive advantages it bestows evaporates; the middle class would be eviscerated, and the poor would be displaced. Like it or not, there is no viable public and/or mass transit in most of the U.S.--we haven't needed it thanks to cheap gas, nor has it been as practical as in Europe thanks to our sprawling landmass.
So, do we heavily invest in public/mass transit now in a crash program, to the tune of trillions of dollars almost all at once, so we can end our reliance on cheap gas? No, that's impractical, too expensive, and no one has either the political will or political capital. Do we just levy those high gas taxes, and see if the dire predictions are false? No, because even if it wouldn't destroy the middle class, it would destroy so many political careers that no one is dumb enough to try it--remember that when oil stayed above $100/barrel for a record number of weeks not long ago and U.S. gas prices stayed at record levels, populist anger boiled so hot that Congress was subpoenaing oil executives and threatening to tax their profits and repeal gas taxes and doing ANYTHING to keep a lid on popular sentiments that threatened to derail every incumbent in their wake.
So no, there will not be high gas taxes in this country, nor should there be. What there should be is a plan to phase out gasoline, not through punitive taxes aimed at the working classes but through taxes and legislative pressures on automakers to phase in certain percentages of electric or hybrid vehicles by target dates. We mandate automakers to include lots of once-expensive tech which has since come down in manufacturing cost; why not, in the name of national security as well as the environment, mandate targeted percentages of electric offerings? If prices of new cars do rise in the short term while early adopters bear the brunt, so be it--the more financially challenged can stick with their old cars for a few years more until costs come down.

There is a debate over whether the Medieval Warm Period (MWP) was global or not. If it were to be conclusively shown that it was a global phenomenon, would you accept that this would undermine the premise that mean surface atmospheric temperatures during the latter part of the 20th Century were unprecedented?
There is much debate over whether the Medieval Warm Period was global in extent or not. The MWP is most clearly expressed in parts of North America, the North Atlantic and Europe and parts of Asia. For it to be global in extent the MWP would need to be seen clearly in more records from the tropical regions and the Southern Hemisphere. There are very few palaeoclimatic records for these latter two regions.
Of course, if the MWP was shown to be global in extent and as warm or warmer than today (based on an equivalent coverage over the NH and SH) then obviously the late-20th century warmth would not be unprecedented. On the other hand, if the MWP was global, but was less warm that today, then current warmth would be unprecedented.
We know from the instrumental temperature record that the two hemispheres do not always follow one another. We cannot, therefore, make the assumption that temperatures in the global average will be similar to those in the northern hemisphere.
So Phil Jones is unsure if the MWP was global in extent and Edward Cook thinks we have very little idea at all. Perhaps the certainty in wikipedia is overstated.

It's not the hard core nutjobs that need to be convinced, an impossible task. It's the moderate but disinterested observer who has been befudled by clever marketing. As with educating people about tabacoo and evolution, it's a slow process but a necassary one.

Also, whenever someone announces that they've discovered that global warming is a big hoax it gets covered in the media and talked about for weeks. But when someone points out that that "discovery" is itself a hoax, the masses never hear about it.

Part of the reason one should be very skeptical of AGW alarmists is their rabies-like demeanor and aggression against all that they perceive as even the slightest heresy against their little modern day apocalypse cult.

Try labelling them "the unconvinced" and go from there.
That would be inaccurate. When have you ever seen one of these "unconvinced" actually get convinced. When they have their questions answered with science they either disappear or counter with more completely unrelated arguments as if that is some sort of rebuttal. That is why the science community gets so frustrated. They cannot win merely by giving a rational response.
I have NEVER seen someone make a decision based on these debates. A real skeptic or unconvinced person would be willing to accept the evidence once enough has been presented. That is why I think they are definitely denialists.

By that I mean there will be people that believe what they want no matter what the evidence. To be clear I mean there's zero solid evidence of Bigfoot yet some will always believe in it.
I think you got your analogies screwed up. Or do you compare AGW to Bigfoot?
I find it bizarre that people refuse to accept we are having an impact on the environment. The evidence is everywhere. I'm not talking global warming both sides of that argument are bordering on religion I'm talking how much the world has changed. Look at common resources. Ever watch any of the logging shows? What they are cutting now are so small no one would have bothered with them 20 or 30 years ago but in many areas it's all that's left and it's so bad that when they do find old growth trees the lumber mills aren't even set up for them. They are simply too rare to bother with.
Deforestation and overlogging are problems that do not depend on the AGW hypothesis. You're making the green fallacy of equating any and all negative changes in the environment to CO2.
Look at swordfish. They said 200 years ago you could all but walk across the Grand Banks because of all the fish. Now the swordfish they take are virtually all immature fish that have yet to reproduce. Most fisheries have collapsed, a fact. When was the last time you saw a butterfly? How many and how often? When I was growing up you'd see them by the hundreds virtually any summer day. Now I see a few a year. Same with frogs.
Speak for yourself. There might be variations in local spiecies populations due to human actions. That has nothing to do with whether CO2 is causing global changes.
Most great apes are down to a few percent of their original populations. It'd take a good sneeze to wipe them out and they are our closest relatives.
Again, caused by deforestation and expanding human land use, not CO2.
People say the snow storms proved global warming was a hoax. Well guess what I live in central Maine and we have already lost most of our snow and it's getting up into the 50s. This is supposed to be the worst time of year for snow and cold. Don't believe anyone or any study if you want.

Medieval warm period wasnt necessarily a period of global warmth. It may have been a period of north-atlantic warmth. Other areas were cooler. This is one of the many areas where the situation is just flat out more complicated than any popular treatment would lead one to believe. Very often one area will be cooler and another hotter and it's bugger-all difficult to properly sort it out and demonstrate a *global* trend without going to a very long time-scale.
And it wasnt named that because it was actually green - it wasnt. It was named that because Ericsson had previously found it very difficult to attract settlers for his previous development, Iceland, because even though it was in fact quite green at the time, it just sounded cold and barren. So he chose a more attractive name for his second development in the interest of marketing.
Certainly true.
Whether or not this is true is far from a settled question. Mans actions influence the environment and vice versa and always have. How much is "significant?" There is some very interesting research that indicates even the tens of thousands of years of farming prior to the industrial revolution may have altered global climate significantly enough to be detected. However in the broader picture, of course, the natural forces that have driven climate change since long before humans evolved are still at work and dwarf anything we can do or likely will be able to do anytime soon.
I think there is a grain of truth in that, but you drastically oversimplify.

Greenland was colonized during a period of global warmth. That it is why it was named that way.
According to the Reverend J. Sephton in his book Eirik the Red's Saga [gutenberg.org], Greenland was named as a marketing ploy by Eirik: "Because," said he, "men will desire much the more to go there if the land has a good name."
Yes, it would have been warmer and greener than it was now, but if there was subterfuge in the naming of the country then I don't imagine that it was a tropical paradise. It also doesn't mean that it was as consistantly warmer across the globe as it is now.
But it is also a distraction. Do you deny that being shot by a gun could kill you, merely because other people have died without being shot. Just because it got warmer then doesn't mean that we are not causing it to get warmer now. It is getting hotter, faster and more globally than it did back then.
Man is not powerful enough to change the earth's climate to any "significant" degree. But that big thermonuclear ball in the sky is. A billion petrochemical fueled cars will not influence the sun.
Nobody has every claimed that we are making the sun hotter. This demonstrates that you really don't understand the problem. The problem is that the heat from the sun is being trapped here. As an analogy, my house stays pretty cool even on hot days without the need for air conditioning. As long as it gets cooler at night, it stays pleasant during the day. But if it stays hot at night, it doesn't get a chance to lose the build-up of heat from the previous day and it gets more unpleasant as after day. The days are not necessarily hotter, but the accumulated heat energy means that each successive day has a larger affect.
Scientists are men that can be influenced by propaganda just like any man can be. I think the climate change scare is just another way for politicians to steal our hard earned money.
The climate change "scare" as you call it was instigated by the scientists, not the politicions. They don't just watch the news and think "yeah, I had better parrot that line too". They just follow their data, and all get to the same place. It is either a giant conspiracy or the truth. Which seems the most likely.
However, if you can come up with ANY evidence to back up the claim that it is the politicians that are leading our scientists around then please present it. Oh, have a look at all those CRU emails that were released. They should be able to tell you the names of the politicians who are giving the orders (if there are any). Come back and let us know.

From your link:
The DCSD did not provide specific statements on actual errors. On this point the MSTI stated "the DCSD has not documented where [Dr. Lomborg] has allegedly been biased in his choice of data and in his argumentation, and ... the ruling is completely void of argumentation for why the DCSD find that the complainants are right in their criticisms of [his] working methods. It is not sufficient that the criticisms of a researcher's working methods exist; the DCSD must consider the criticisms and take a position on whether or not the criticisms are justified, and why.
A Dutch think tank, HAN, Heidelberg Appeal the Netherlands, published a report in which they claimed 25 out of 27 accusations against Lomborg to be unsubstantiated or not to the point.[13] A group of scientists with relation to this think tank also published an article in 2005 in the Journal of Information Ethics,[14] in which they concluded that most criticism against Lomborg was unjustified, and that the scientific community misused their authority to suppress Lomborg.
I assume you've read it and know that there are still plenty of other criticisms (like this new book) but as for peer-review and open dialogue I think it's hard to say that Lomborg hasn't had his work examined and even harder to say that he hasn't been forthcoming in responding to detractors in a far more transparent way than any journal I've ever read. I've never read TSE but I can't say that I understand where you get the "frothing" part of his response. Maybe you should imagine it being r
