Freeman Dyson on ‘heretical’ thoughts about global warmimg | Watts Up With That?

My first heresy says that all the fuss about global warming is grossly exaggerated. Here I am opposing the holy brotherhood of climate model experts and the crowd of deluded citizens who believe the numbers predicted by the computer models. Of course, they say, I have no degree in meteorology and I am therefore not qualified to speak.
But I have studied the climate models and I know what they can do. The models solve the equations of fluid dynamics, and they do a very good job of describing the fluid motions of the atmosphere and the oceans. They do a very poor job of describing the clouds, the dust, the chemistry and the biology of fields and farms and forests. They do not begin to describe the real world that we live in.
The real world is muddy and messy and full of things that we do not yet understand. It is much easier for a scientist to sit in an air-conditioned building and run computer models, than to put on winter clothes and measure what is really happening outside in the swamps and the clouds. That is why the climate model experts end up believing their own models.

Bill Nye’s Embarrassing Face-off with Tucker Carlson on Climate Change

Since the premiere of his new nighttime show, Carlson has frequently confronted the dogma of man-made global warming, pushing “experts” to cite data and evidence to back up their claims rather than allowing them to repeat well-worn platitudes about a scientific consensus and the planet’s impending doom. In January, Tucker took on California State University professor Joseph Palermo, who wrote, “If President Trump and his cohort believe the science of global warming is bogus, then they shouldn’t be allowed to use the science of the Internet for their Twitter accounts” based on the commonly accepted factoid that “98 percent of all scientists” believe the climate is changing because of human activity. When Carlson repeatedly asked Palermo to give the source of that figure, which Carlson correctly said was unknowable, the professor couldn’t do it. Climate fail.

But it was Carlson’s takedown of Bill Nye the Science Guy, a television personality and celebrity climate promoter, that exposes the intellectual chicanery behind this crusade. During an interview on Carlson’s show on February 27, Nye goofily claimed that people who question claims about global warming suffer from cognitive dissonance: “We in the science community are looking for information why climate change deniers, or extreme skeptics, do not accept the overwhelming scientific evidence on climate change.” Nye went on to say that denial is denial, the evidence is overwhelming, and the question of whether humans are causing climate change is “not an open question, it’s a settled question.”

Now usually when these charges are made by someone who purports to possess expertise in climate science (Nye has a degree in mechanical engineering), the interviewer acquiesces, immediately surrendering the debate to the climate activist. But Carlson wouldn’t back down: “To what degree is climate change caused by human activity? . . . Is it 100 percent, is it 74.3 percent? If it’s settled science, please tell us to what degree human activity is responsible.”

Nye started to get uncomfortable, well aware he had no certain answer to this so-called settled question, since climate scientists cannot agree how much human activity contributes to climate change. (Even the Intergovernmental Panel on Climate Change is suitably vague on this issue; the IPCC’s 2013 report states that it is “extremely likely that more than half of the observed increase in global average surface temperature from 1951 to 2010 was caused by the anthropogenic increase in greenhouse gas concentrations and other anthropogenic forcings together. The best estimate of the human-induced contribution to warming is similar to the observed warming over this period.”)

This is when Nye went off the rails, refusing to specify the degree to which people cause climate change and instead blaming us for the speed that climate change is happening: “Instead of happening at time scales of millions of years or let’s say 15,000 years, it’s happening on a time scale of decades and now years.” Or, you know, whatever. He went on to tell Carlson humans are “100 percent” responsible for the rate of climate change and it’s happening catastrophically fast. This spun him into a really weird (and unscientific) spot where he started lamenting the fact that global warming has caused us to avoid another Ice Age — perhaps unaware that most people would consider freezing to death a horrible fate — and told Carlson another Ice Age “ain’t gonna happen because of you and me.” Yay CO2!

Sensing he was getting cornered by Carlson, Nye pivoted to the next tactic often used by uninformed and misleading climate activists: the personal attack. “Let me ask you this. Why aren’t you concerned about it? Don’t you have four children? Why aren’t you concerned about climate change?” Because if you don’t care about climate change, you don’t care about your children.

Then right before my eyes, Nye turned into my old college political-science professor, who — no matter what the subject was at the time — would end his lecture by ranting about the Vietnam War. Nye babbled about the weather back in 1750, grape growers in Europe, pesticides in the Midwest, and something about pine-bark beetles in Wyoming. (This is another common tactic of climate alarmists, they talk over you while throwing out unverifiable factoids that make them sound informed when they’re usually just making stuff up.)

While it’s easy to dismiss Nye’s interview as a kooky one-off appearance from an unprepared celebrity scientist, he sadly represents the lack of integrity by most climate-change pushers. They move goalposts, manufacture facts, resist honest debate, and resort to smear tactics when confronted with specific questions they cannot answer. As Carlson said to Nye, “You really don’t know, and you bully people who ask questions.” Good thing Carlson is there to bully back for once.

What did Mann win?

Popehat explains:

The DC Circuit adopted the standard that the vast majority of states use for their anti-SLAPP statutes — the plaintiff only has to produce admissible evidence which, if accepted, is legally sufficient to win. That's the same standard courts apply to motions for summary judgment — motions in which the defendant argues that there's not enough evidence for the case to go to a jury. Practically that means that if the complaint is bogus as a matter of law (for instance, if it targets speech that is clearly just hyperbole or opinion), or if the plaintiff has no evidence to support it, the defendant wins — but if the complaint is legally plausible, and the plaintiff has any evidence to support it, the plaintiff wins.

....

Steyn's and CEI's Articles: The DC Court of Appeal held that the trial court was correct to deny the anti-SLAPP motion by Steyn, CEI, and Simberg. Mann won, and Steyn, CEI, and Simberg lost, that part of the appeal. The result is notable and, for several reasons, concerning.

There are two key elements to this part of the decision: the distinction between opinion and fact, and the question of what constitutes proof of malice.

Once again, only false statements of provable fact may be defamatory. Opinions, arguments, and hyperbole may not unless they imply false provable facts. "Ken is a jerk" can't be defamatory because it's not objectively provable; "I hacked Ken's email and he's a crook" might conceivably be defamatory because it could imply false facts.

Here, both Steyn's and Simberg's articles were replete with hyperbole, rather strongly signalling opinion. Moreover, they both disclosed the facts that they were relying upon — the hockey stick that another scientist [edited to correct: not Mann] called a "trick" to "hide a decline." I think — like others — that the better and more reasonable interpretation of these writings is that Steyn and Simberg were offering overt argument and opinion based on disclosed facts. You might disagree with the fairness of their conclusions — for instance, you might accept Mann's explanation of what the other scientist [edited: not Mann]meant by "trick," or believe that it's unreasonable not to agree with academic institutions that exonerated Mann — but conclusions based on data aren't defamatory even if they are unfair or unreasonable. That's classic protected speech.

The DC Court of Appeals, however, focused on a lack of overt signals like "in my view" or "in my opinion" or "I think" — silly formalism, in my view, but a pointer to practitioners of how one can manage libel risks. The court also focused on the fact that calling something "fraudulent" or "data manipulation" could possibly be interpreted as a statement of provable fact. The problem with this argument, I think, is that it is very selective about what context it considers. Steyn and Simberg are overtly operating in the context of a scientific culture in which someone has talked about a "trick" in presenting data in support of an argument to "hide" an inconvenient fact. That is the underlying fact framing their opinion. The fact is undisputed even if the interpretation of it is not. Their use of vivid and argumentative language helps establish that they are drawing conclusions, not asserting new (and unspecified) facts.

It's important to understand what the Court of Appeals found, though. It didn't find that Steyn's and Simberg's articles stated facts, let alone false ones. It simply found that Mann presented evidence that, if believed, could allow a jury to conclude that the articles stated facts rather than opinions. The court found he created an arguable issue, in other words. I don't agree, but that's much different than deciding that the articles were factual rather than opinion.

Next, the Court of Appeals found that Mann had presented evidence that was legally sufficient to show that Steyn and Simberg acted with malice. Malice, in this context, doesn't mean ill will — it means with knowledge that statements were false or recklessness about whether or not they were false. Mann has to meet that standard because he's a public figure — only false statements about him made with malice are defamatory. The court found that Mann had presented evidence of widely circulated studies and findings exonerating him, and that the existence of those studies could be accepted by a jury as adequate proof of knowledge that the factual allegations were false.

I think the Court's decision here was, at a minimum, badly framed. The entire point of Steyn's and Simberg's posts was quis custodiet ipsos custodes — that the scientific and academic community's policing of alleged wrongdoing by its own is incredible and unreliable when it is defending ideologically cherished consensus.

The Climate Science Challenge | Scott Adams' Blog

The Climate Science Challenge | Scott Adams' Blog

So today’s challenge is to find a working scientist or PhD in some climate-related field who will agree with the idea that the climate science models do a good job of predicting the future.

Notice I am avoiding the question of the measurements. That’s a separate question. For this challenge, don’t let your scientist conflate the measurements or the basic science of CO2 with the projections. Just ask the scientist to offer an opinion on the credibility of the models only.

Remind your scientist that as far as you know there has never been a multi-year, multi-variable, complicated model of any type that predicted anything with useful accuracy. Case in point: The experts and their models said Trump had no realistic chance of winning.

What I Learned about Climate Change: The Science is not Settled – Medium

What I Learned about Climate Change: The Science is not Settled – David Siegel on Medium

What is your position on the climate-change debate? What would it take to change your mind?

If the answer is It would take a ton of evidence to change my mind, because my understanding is that the science is settled, and we need to get going on this important issue, that’s what I thought, too. This is my story.

....

Recently, a friend challenged those assumptions. At first, I was annoyed, because I thought the science really was settled. As I started to look at the data and read about climate science, I was surprised, then shocked. As I learned more, I changed my mind. I now think there probably is no climate crisis and that the focus on CO2 takes funding and attention from critical environmental problems. I’ll start by making ten short statements that should challenge your assumptions and then back them up with an essay.

1 Weather is not climate. There are no studies showing a conclusive link between global warming and increased frequency or intensity of storms, droughts, floods, cold or heat waves. The increase in storms is simply a result of improved measurement methods. There has been no real increase.

2Natural variation in weather and climate is tremendous. Most of what people call “global warming” is natural, not man-made. The earth is warming, but not quickly, not much, and not lately.

3There is tremendous uncertainty as to how the climate really works. Climate models are not yet skillful; predictions are unresolved.

4New research shows fluctuations in energy from the sun correlate very strongly with changes in earth’s temperature, better than CO2 levels.

5CO2 has very little to do with it. All the decarbonization we can do isn’t going to change the climate much.

6There is no such thing as “carbon pollution.” Carbon dioxide is coming out of your nose right now; it is not a poisonous gas. CO2 concentrations in previous eras have been many times higher than they are today.

7Sea level will probably continue to rise — not quickly, and not much. Researchers have found no link between CO2 and sea level.

8The Arctic experiences natural variation as well, with some years warmer earlier than others. Polar bear numbers are up, not down. They have more to do with hunting permits than CO2*.

9No one has demonstrated any unnatural damage to reef or marine systems. Additional man-made CO2 will not likely harm oceans, reef systems, or marine life. Fish are mostly threatened by people, who eat them. Reefs are more threatened by sunscreen than by CO2.

10The Intergovernmental Panel on Climate Change and others are pursuing a political agenda and a PR campaign, not scientific inquiry. There’s a tremendous amount of trickery going on under the surface*. Could this possibly be right? Is it heresy, or critical thinking — or both? If I’ve upset or confused you, let me guide you through my journey.

Investigating global warming using a new graph style | Watts Up With That?

Investigating global warming using a new graph style | Watts Up With That?

Because there is so much detail in a contour map, it is best to look at a large image. I think that I am limited to a small image in this article, so I will put a link after the small image, which will take you to a large image that I put on the Photobucket website. I hope that this works, it is the first time that I have tried this. If you can’t get to the large image, then you could try magnifying the small image using your browser. I know that Chrome has a Zoom control, and I assume that other browsers will have something similar.

For a large image of this contour map, from the Photobucket website, click this link:
http://i1042.photobucket.com/albums/b424/mta-graphs/Contour%201880%20to%202015%20-%20big%20with%20copyright_zps6tvnym4k.pngThe legend for global warming contour maps is here:Now that you have looked at a contour map, and looked at the legend, we can discuss what is on the map.
Along the bottom of the contour map, there is a line of what appear to be small red flames. These are not real flames, but they do represent a source of heat. These are the natural warming events, like El Nino and the Blob. If you count them, then you will find that there are about 46 of them between 1880 and 2015. Some of them merge together, so an exact count is difficult. That is about one natural warming event every 3 years, and I believe that El Nino’s occur about once every 2 to 5 years, so the number seems about right.
There are often small black regions between the natural warming events. I use black to show cooling, so these small black regions are either the cooling phase of an El Nino, or possibly a La Nina.
Now look at the big black area near the middle of the graph, As I said before, I use black to show cooling, so this appears to be a large cooling event. When I first found this, I thought that it might be an error in the graph. I checked it carefully, and found that it was an approximately 40 year cooling trend, that started about 1935, and finished in about 1975. As soon as I saw the year 1975, I knew what this was. I remembered that in 1976 there was a scare about a possible ice age happening. Time magazine ran 2 cover stories, one about “The coming Ice Age”, and the other about “How to survive the coming Ice Age”. I don’t believe that Time magazine would invent these stories with no evidence. It would make sense if some scientist noticed the 40 year cooling trend, and said something to somebody.

A Fascinating Survey on Climate Change of Scientists (and Engineers) in Alberta, Canada | The Lukewarmer's Way

A Fascinating Survey on Climate Change of Scientists (and Engineers) in Alberta, Canada | The Lukewarmer's Way

From the abstract: “This paper examines the framings and identity work associated with professionals’ discursive construction of climate change science, their legitimation of themselves as experts on ‘the truth’, and their attitudes towards regulatory measures. Drawing from survey responses of 1077 professional engineers and geoscientists, we reconstruct their framings of the issue and knowledge claims to position themselves within their organizational and their professional institutions.”

From the paper: “A survey of scientists in Alberta Canada produced 5 broad groupings of opinion.

The largest group of APEGA respondents (36%) draws on a frame that the researchers label ‘comply with Kyoto’. In their diagnostic framing, they express the strong belief that climate change is happening, that it is not a normal cycle of nature, and humans are the main or central cause. They are the only group to see the scientific debate as mostly settled and the IPCC modeling to be accurate, e.g., ‘I believe that the consensus that climate change is occurring is settled.

The second largest group (24%) express a ‘nature is overwhelming’ frame. In their diagnostic framing, they believe that changes to the climate are natural, normal cycles of the Earth. Their focus is on the past: ‘If you think about it, global warming is what brought us out of the Ice Age.’ Humans are too insignificant to have an impact on nature.’

Ten percent of respondents draw on an ‘economic responsibility’ frame. They diagnose climate change as being natural or human caused. More than any other group, they underscore that the ‘real’ cause of climate change is unknown as nature is forever changing and uncontrollable. Similar to the ‘nature is overwhelming’ adherents, they disagree that climate change poses any significant public risk and see no impact on their personal life. They are also less likely to believe that the scientific debate is settled and that the IPCC modeling is accurate.

‘Fatalists’, a surprisingly large group (17%), diagnose climate change as both human- and naturally caused. ‘Fatalists’ consider climate change to be a smaller public risk with little impact on their personal life. They are sceptical that the scientific debate is settled regarding the IPCC modeling: ‘The number of variables and their interrelationships are almost unlimited – if anyone thinks they have all the answers, they have failed to ask all of the questions.’

The last group (5%) expresses a frame the researchers call ‘regulation activists’. This frame has the smallest number of adherents, expresses the most paradoxical framing, and yet is more agentic than ‘comply with Kyoto’. Advocates of this frame diagnose climate change as being both human- and naturally caused, posing a moderate public risk, with only slight impact on their personal life. They are also sceptical with regard to the scientific debate being settled and are the most indecisive whether IPCC modeling is accurate: ‘the largest challenge is to find out what the real truth is… I don’t know what the impact really is. I suspect it is not good.’

They believe that the Kyoto Protocol is doomed to failure (‘can’t do it, even though we should’), yet they motivate others most of all to create regulation: ‘Canada should implement aggressive policies to reduce GHG emissions in the spirit of the Kyoto Accord.’ They also recommend that we define and enact sustainability/stewardship, reduce GHGs, and create incentives.”

 Climate Change: Is it Real and Important

Earth Day: 22 Ways to Think about the Climate-Change Debate | Foundation for Economic Education

Earth Day: 22 Ways to Think about the Climate-Change Debate | Foundation for Economic Education

Reasonable people can disagree about the nature and extent of climate change. But no one should sally forth into this hostile territory without reason and reflection.

“Some scientists make ‘period, end of story’ claims,” writes biologist and naturalist Daniel Botkin in the Wall Street Journal, “that human-induced global warming definitely, absolutely either is or isn’t happening.”

These scientists, as well as the network of activists and cronies their science supports, I will refer to as the Climate Orthodoxy. These are the folks who urge, generally, that (a) global warming is occurring, (b) it is almost entirely man-made, and (c) it is occurring at a rate and severity that makes it an impending planetary emergency requiring political action. A Climate Agnostic questions at least one of those premises.

Trying to point out the problems of the Climate Orthodoxy to its adherents is like trying to talk the Archbishop of Canterbury into questioning the existence of God. In that green temple, many climatologists and climate activists have become one in the same: fueled both by government grants and zealous fervor.

Room for debate

But the debate must go on, even as the atmosphere for dialogue gets increasingly polluted. The sacralization of climate is being used as a great loophole in the rule of law, an apology for bad science (and even worse economics), and an excuse to do anything and everything to have and keep power.

Those with a reasoned agnosticism about the claims of the Climate Orthodoxy will find themselves in debate. It’s April 22nd — Earth Day. So I want to offer 22 ways to think about the climate-change debate. I hope these points will give those willing to question man-made climate change some aid and comfort.

1. Consider the whole enchilada

First, let’s zoom out a few orders of magnitude to look at the Climate Orthodoxy as a series of dots that must be connected, or better, a series of premises that must be accepted in their totality.

• The earth is warming.
• The earth is warming primarily due to the influence of human beings engaged in production and energy use.
• Scientists are able to limn most of the important phenomena associated with a warming climate, disentangling the human from the natural influence, extending backward well into the past.
• Scientists are able then to simulate most of the phenomena associated with a warming earth and make reasonable predictions, within the range of a degree or two, into the future about 100 years.
• Other kinds of scientists are able to repackage this information and make certain kinds of global predictions about the dangers a couple of degrees will make over that hundred years.
• Economists are able to repackage those predictions and make yet further predictions about the economic costs and benefits that accompany those global predictions.
• Other economists then make further predictions based on what the world might be like if the first set of economists is right in its predictions (which were based on the other scientists’ predictions, and so on) — and then they propose what the world might look like if certain policies were implemented.
• Policymakers are able to take those economists’ predictions and set policies that will ensure what is best for the people and the planet on net.
• Those policies are implemented in such a way that they work. They have global unanimity, no defections, no corruption, and a lessoning of carbon-dioxide output that has a real effect on the rate of climate change — enough to pull the world out of danger.
• Those policies are worth the costs they will impose on the peoples of the world, especially the poorest.

That is a lot to swallow. And yet, it appears that the Climate Orthodoxy requires we accept all of it. Otherwise, why would the Intergovernmental Panel on Climate Change (IPCC) publish a document called “Summary for Policymakers”?

2. Models are not evidence

The problem with models is that they are not reality. Whenever we try to model complex systems like the climate, we’re only getting a simulacrum of a system, designed to represent projected scenarios. So when a climatologist presents a model as evidence, he is playing a kind of game. He wants you to think, by dint of computer wizardry, that he has drawn for you a picture of the world as it is. But he hasn’t. And if observation of surface temperatures over the last 18 years has shown one thing, it’s that climate models have been inadequate tools for forecasting complex natural phenomena.

3. Forecast is not observation

In the first IPCC assessment of 1992, the authors wrote, “Scenarios are not predictions of the future and should not be used as such.” Whether one views the models as predictions or as scenarios, the evidence is barely within the most conservative of these in the most recent assessment, which is essentially designed to hide good news.

When one attempts to forecast — that is, to tell the future — one is not engaging in observation. That is not to claim that prediction isn’t a part of the scientific enterprise; it’s simply to say that when one’s predictions (or scenarios) are off, one’s theory is suspect, and it must be modified and tested again. Any theory, and any forecast scenarios on which it’s based, have to be tested in the crucible of observation. The Climate Orthodoxy has thus far failed that test.

4. Climate systems are complex

As I alluded to above, climate systems are complex systems. And complex systems are notoriously immune to certain types of prediction and forecast. As Edward Lorenz famously taught us when he coined the term “butterfly effect,” the slightest changes in initial conditions can give rise to wild, unpredictable outcomes in the system. It’s no different for a simulation. “I realized,” said Lorenz of his findings, “that any physical system that behaved non-periodically would be unpredictable.” Now, those concerned about climate change will try to use this perspective to suggest changes to the atmosphere could cause wild, unpredictable climatic catastrophes. And that might turn out to be true. (But it might not. We’ll discuss Pascal’s Climate Wager later.) What we should be concerned about for now is how easy it is for a single tiny error (or purposeful fudge) in a climate model to generate ranges that, though they can feed hysteria, are out of touch with reality.

5. Garbage in equals garbage out

Complex systems also make modeling difficult to undertake because a model is a kind of simulation whose success turns on the accuracy of inputs. Computer scientists have an apt saying for such simulations: “Garbage in, garbage out.” If any of your variables are in error, your results are suspect. And the more variables you introduce, the more likely you are to introduce errors. But for the model to resemble reality, you have to be more granular by including more and more variables that represent causal relationships in the world. As more variables get introduced, the likelihood of introducing false inputs goes up proportionally. And those errors compound. In The Black Swan, Nicolas Nassim Taleb writes:

Simply, we are facing nonlinearities and magnifications of errors coming from the so-called butterfly effects ... actually discovered by Lorenz using weather forecasting models. Small changes in input, coming from measurement error, can lead to massively divergent projections — and that generously assumes we have the right equations.

In other words, the lower “res” the model, the less it conforms to reality’s details. The higher “res” the model, the more likely it is to be infected with errors. This is one of the great paradoxes of modeling.

6. Data can be detached

The problem with numbers is that they’re sometimes detached from the phenomena they’re meant to describe. If we see a record of a person’s body temperature from 1969 — at 99.1 degrees — we might assume he had a fever. But knowing the context of that measurement may lead us to tell a different story about what caused his temperature at that time: for example, that the man had been sitting in a hot tub. Climate data from the past can offer even less context, clarity, and accuracy.

But let’s suppose all the world’s thermometers — both satellite and land — have neither heat-island effects nor any other distortions, and that they offer an accurate description of the earth’s temperature. Let us also assume that the temperature readings over the last hundred years are completely accurate and represent the planet as a whole, and that the temperature data derived from inferential methods such as ice core samples and tree rings also paint an accurate picture of surface temperatures well into the past, which is doubtful.

We are still left with a problem: We cannot simply look at the outputs of the climate system (temperature), because they are linked to all-important inputs — that is, those factors that caused any changes in temperature. The inability for climate scientists to tell a more conclusive causal story about factors in past warming is another reason to remain agnostic about trends over longer timescales.

7. Decomposability is a virtual impossibility

Another serious problem with the theory of anthropogenic global warming (AGW) is that, if it is a theory at all, it seems to be a cluster of interconnected theories and interconnected models. Let that settle for a moment. Consider that the IPCC, the central climate-science organization whose job is to give the definitive word on climate change, has to assemble the work of hundreds, maybe thousands, of scientists and weave it into a comprehensive report. But as Norgaard and Baer write in Bioscience, “Models developed and heretofore interpreted within individual scientific communities are taken out of their hands, modified, and used with other models in ways over which the original scientific communities no longer have control.”

Now, in stitching together the various individual theories, studies, and models of such a diverse and inevitably error-prone community, the problem goes deeper. Never mind that the IPCC central committee has deep incentives to interpret the data in a way that creates the impression of a single, uniform theory. Suppose that every climate scientist that gets picked by the IPCC for its report claims 95 percent confidence. Even if each scientist were 95 percent certain of his particular prediction or set of parameters, we can’t be so certain about the agglomeration of 10 scientists’ opinions about disparate phenomena, much less 50. Nor can any given scientist be 95 percent confident about the work of any other scientist.

8. Stats stand in for certainty

People crave certainty, and politicians want to provide it. So when we hear that a scientist is 95 percent confident about his or her conclusions, we feel like that’s close enough, derived as it presumably is through some sort of statistical analysis. “Yet since things are ultimately uncertain,” writes theoretical mathematician William Byers:

We satisfy this need by creating artificial islands of certainty. We create models of reality and then insist that the models are reality. It is not that science, mathematics, and statistics do not provide useful information about the real world. The problem lies in making excessive claims for the validity of these methods and models and believing them to be absolutely certain.

Byers’s book The Blind Spot: Science and the Crisis of Uncertainty is a welcome antidote to this sort of scientific hubris.

Climatologist Judith Curry put matters a little differently. When a journalist asked her how the 95 percent number was determined, she replied, “The 95% is basically expert judgment, it is a negotiated figure among the authors. The increase from 90–95% means that they are more certain. How they can justify this is beyond me.”

The reporter then asked if it was really all so subjective. Curry’s reply: “As far as I know, this is what goes on. All this has never been documented.”

9. AGW might not be a theory at all

What makes a scientific theory a theory at all? This has been debated among philosophers of science, but most people generally agree that a certain set of minimum criteria should be in place. Among them, at least, are these:

1. Is the theory testable? Can we formulate hypotheses grounded in the theory, then figure out a way to test the hypotheses?
2. Is the theory falsifiable? Is there evidence that could call the theory into question? What evidence would exclude the theory?
3. Does the theory unify? Does the theory unify seemingly unrelated phenomena under a single explanatory framework?

AGW is not testable in any laboratory sense, of course, but many natural phenomena are not. And yet we’ve already discussed the problems of testing models against available evidence — considering the models’ hypotheses and seeing whether these track with what we can observe. One might argue that models stand for hypotheses, and suffice for a testability criterion. But this is unclear.

Perhaps the most damning of the three for AGW is the falsifiability criterion. That is, the Orthodoxy has created a situation in which models play a major role in the theoretical framework. But when the models fail to track with observation, the Orthodoxy claims the timescales are not sufficient to determine a climate trend — for example, that discussing the pause of the last 18 years is “cherry picking.” Fair enough. But then what sort of data would count to falsify the theory? And what, going forward, is a time scale sufficient to determine a climate trend? 100 years?

If we accept these longer timescales as sufficient to smooth out natural variability, we might reasonably ask the Orthodoxy to remain agnostic about AGW while another 70 years of data come in. (After all, they have had to rely on spurious proxies to “trick” temperature trends in the past.) But the Orthodoxy then changes tack and argues that’s too long to wait! After all, we might be going through an emergency that requires immediate action. So, despite the insufficient timescale, they expect everyone to accept the climate consensus as the basis for policymakers’ faith-based initiatives.

Finally, does AGW unify diverse phenomena under a single explanatory framework? AGW is meant to explain everything from ocean acidification to melting sea ice, to rising sea levels, to regional desertification. The trouble is with the explanatory part. When taken in isolation, each of these purported consequences of global warming either aren’t happening as predicted, or, if they are, they can be explained by factors outside AGW theory. So it’s not clear that AGW satisfies any unification criterion, either.

10. It’s matter of degree

What if the Climate Orthodoxy is wrong and the “lukewarmists” like Judith Curry turn out to be right? If we look at the empirical data over the last 30 years or so, they might be. As Rational Optimist author writes, “I found myself persuaded by the middle-of-the-road, ‘lukewarm’ argument — that CO2-induced warming is likely but it won’t be large, fast or damaging.” The Climate Orthodoxy might have been hyperventilating over a degree of warming over a century. (And, of course, policies driven by hysteria could mean the poorest people might be prevented from joining the middle class for the sake of an almost imperceptible change.)

11. Pascal’s Climate Wager

Suppose we all agreed that 100 years of accurate temperature data would be sufficient to determine a climate trend. The Climate Orthodoxy argues that we must act now to prevent climate change, in case they are right. People familiar with theology will recall this is the analogous to Pascal’s Wager, in which 17th-century Christian philosopher Blaise Pascal tells us we’d better believe in God, Heaven, and Hell. If we believe and we’re wrong, we haven’t lost anything, according to Pascal. But if we disbelieve and we’re wrong, we have eternity to suffer. Similarly, we must believe, suffer, and sacrifice now to stave off climate change.

There are a number of problems with this rationale, but the biggest one is rather ironic. There is no viable political climate solution currently on the table that is capable of mitigating any predicted warming. Taking the IPCC’s own assumptions, Patrick Michaels and Paul “Chip” Knappenberger found that there is no winning “wager” here:

Assuming the IPCC’s value for climate sensitivity (i.e., disregarding the recent scientific literature) and completely stopping all carbon dioxide emissions in the US between now and the year 2050 and keeping them at zero, will only reduce the amount of global warming by just over a tenth of a degree (out of a total projected rise of 2.619°C between 2010 and 2100).

If you think that a rise of 2.482°C is vastly preferable to a rise of 2.619°C then all you have to do is set the carbon tax large enough to drive U.S. emissions to zero by mid-century — oh yeah, and sell that tax to the American people.

So even if all the models turn out to be true, there is little we can do with policy at this point. So unlike Pascal’s Wager, there is no amount of repenting and belief that could save us. We’re either all going to climate hell, anyway, or something ain’t right. The whole conversation about “climate action” appears to be moot at this point. Don’t believe it?

12. The debate is not over, and the science is not settled

Freeman Dyson, a brilliant theoretical physicist, is no man of the right. But he is intellectually honest enough to wear the mantel of “heretic.” Here’s why:

I am especially unimpressed by the claim that a prediction of rapid and dangerous warming is “settled science,” as firm as evolution or gravity. How could it be? It is a prediction! No prediction, let alone in a multi-causal, chaotic and poorly understood system like the global climate, should ever be treated as gospel. With the exception of eclipses, there is virtually nothing scientists can say with certainty about the future. It is absurd to argue that one cannot disagree with a forecast. Is the Bank of England’s inflation forecast infallible?

Indeed. And to say that the debate is over is not to say that those willing to debate have nothing to say. It is rather to say that you have turned off your curiosity, your humility, and your willingness to engage in discourse so that you can get what you want.

And what should we say about all this “consensus” talk? Science writer Ronald Bailey (no agnostic about climate change) wisely says:

One should always keep in mind that a scientific consensus crucially determines and limits the questions researchers ask. And one should always worry about to what degree supporters of any given scientific consensus risk succumbing to confirmation bias. In any case, the credibility of scientific research is not ultimately determined by how many researchers agree with it or how often it is cited by like-minded colleagues, but whether or not it conforms to reality.

13. Climate science isn’t climate policy

One of the biggest problems with the Climate Orthodoxy is that one set of experts that is cocksure about the science really has no expertise in the economics of climate change or in climate-change policy. How in the world is an expert in albedo effects going to have anything meaningful to say about whether climate change is good or bad for the world today — much less 50 years into the future? This profound disconnect has never stopped scientists like James Hansen from advocating for certain types of policies.

Seeing this disconnect, however, the Orthodoxy has begun training up so-called specialists in the economics of climate change, led by such “experts” as Sir Nicholas Stern, whose models and predictions are the stuff of both speculation and spectacle. More tempered in his prognostications is Yale’s William Nordhaus, but economists such as Robert Murphy offer very good reasons to question Nordhaus’s almanac, as well.

If you think modeling the climate is hard, try modeling an economy. As economist Arnold Kling writes,

I think that if the press were aware of the intellectual history and lack of scientific standing of the models, it would cease rounding up these usual suspects. Macroeconometrics stands discredited among mainstream academic economists. Applying macroeconometric models to questions of fiscal policy is the equivalent of using pre-Copernican astronomy to launch a satellite or using bleeding to treat an infection.

Whatever the pedigree of the economist, his laurels, or his letters, mixing macrometeorology with macroeconomics is like trying to read tea leaves.

14. The climate orthodoxy is inherently corruptive

Here’s the heretic Dyson again:

The politicians and the public expect science to provide answers to the problems. Scientific experts are paid and encouraged to provide answers. The public does not have much use for a scientist who says, “Sorry, but we don’t know.”

He’s right. It is nearly impossible to inoculate science from the influence of those who pay the bills. As I wrote in “The Climate Complex Strikes Back” (Freeman, February 2015), “That government money shouldn’t corrupt is just another application of the unicorn fallacy so common among well-meaning greens.” And it’s even tougher not to develop blind spots and biases when those who fund you claim to be on the side of the angels. That is why we must put our faith not in centralized hierarchies of experts but in the Republic of Science itself.

15. Reasoned agnosticism is not “denial”

Godwin’s law surfaces quickly in the debates about global warming. Here’s Botkin again:

For me, the extreme limit of this attitude was expressed by economist Paul Krugman, also a Nobel laureate, who wrote in his New York Times column in June, “Betraying the Planet” that “as I watched the deniers make their arguments, I couldn’t help thinking that I was watching a form of treason — treason against the planet.” What had begun as a true scientific question with possibly major practical implications had become accepted as an infallible belief (or if you’re on the other side, an infallible disbelief), and any further questions were met, Joe-McCarthy style, “with me or agin me.”

Of course, the term “denier” is meant to evoke Holocaust denial.

16. AGW might be beneficial on net

If Stern and Nordhaus (see #11) can engage in economic speculation, then we can, too. In fact, when we look back at warmer periods in the history of civilization, we see relative flourishing.

According to Matt Ridley, writing in the UK Spectator, Professor Richard Tol of Sussex University aggregated 14 major academic papers about the future effects of climate change. Tol determined that things look rosier than the Orthodoxy would have us believe:

Professor Tol calculated that climate change would be beneficial up to 2.2°C of warming from 2009 (when he wrote his paper). This means approximately 3°C from pre-industrial levels, since about 0.8°C of warming has happened in the last 150 years.

And in a more recent paper, Tol looks back over the last 100 years. He concludes that climate change raised human and environmental welfare during the 20th century:

By how much? He calculates by 1.4 per cent of global economic output, rising to 1.5 per cent by 2025. For some people, this means the difference between survival and starvation.

Sure, it’s speculative, even looking back. But isn’t it just as likely that there will be benefits as costs? It might turn out that if the planet does warm a couple of degrees, there will be new forms of flourishing.

17. One hundred years of certitude

One wonders what people in 1915 would have thought about our lives today. The pace of technological change has been staggering. And though a few people tried to make predictions, they were not cut out for the task. Likewise, we cannot readily say what forms of energy we’ll use, and what technologies they will power. As Troy University economist Daniel Sutter reminds us,

A dynamic market economy will feature too much creative destruction to allow detailed planning for the distant future. Nothing is sure in a market economy ten years from now, much less 100 years, and discounting in cost-benefit analysis simply reflects this reality. The economic future becomes more predictable when government controls economic activity, but then stagnation results. Discounting in climate change economics tells us to create wealth to protect future generations. Economic freedom and the institutions of the market economy, not central planning of energy use, is the prudent policy approach to a changing climate.

Inherent in our inability adequately to plan and predict is a recommendation that we adapt instead.

18. Adaptation as policy prescription

If the climate is warming some, and it might be, then what is the best policy? One can make a powerful case for adaptation. Adaptation is not about doing nothing. It means liberalizing the world on a number of dimensions of economic freedom to ensure that countries are rich enough to be resilient. A wealthy and adaptive people like the Dutch can figure out how to live with rising waters. A rich and resilient people like the Hong Kong Chinese can figure out how to build a city-state on a rock in 50 years. A rich and resilient citizenry of the world should be able to handle what a degree or two of change in average global temperature has in store for us — especially as we will undergo untold technological transformations over the next decade or two.

19. Climate policy has a defector problem

The problem with climate-change policies like carbon taxes is that they require near-global unanimity to work. That is, if the United States adopts a carbon tax, energy becomes more expensive for Americans. But if energy becomes more expensive here, it might be less expensive in other parts of the world. And, indeed, businesses and the energy industry will engage in energy arbitrage. Developing countries like India, China, Brazil, and Russia will welcome these energy arbitrageurs with open arms. They might develop even as we stagnate. And they should: they are lifting billions of people out of poverty. But there’s a problem here for climate policy. Every signatory to a climate treaty has strong incentives to defect. And as defectors do their thing, carbon continues to pour into the atmosphere. Nothing changes to mitigate climate change; industry simply shifts around.

20. Climate policy has an efficacy problem

Suppose we don’t accept Pascal’s Climate Wager and we conclude that no climate policy under consideration will do much to mitigate warming. Those who claim that action is vital respond to this claim by saying, “We have to start somewhere!” But if you’re conceding that no policy under consideration does very much, why would you start with a failed policy? It appears to be more empty rhetoric used to justify an unprecedented level of taxation designed to feed some of the most insatiable and predatory governments in the world.

21. Climate policy has a corruption problem

Earlier, I suggested that the Climate Orthodoxy has a corruptive influence on science. We shouldn’t stop there. The “climate industrial complex“ is large and growing. Scores of green energy companies are on the take, donating campaign contributions to politicians who control the purse strings at the Department of Energy. Legacy energy utilities lick their chops, seeing opportunities to game the system in a carbon-tax environment that is unfavorable to their competitors. Traders get in on energy credit schemes. Green NGOs play “Baptists” to all the corporate “bootleggers,” and when you scrutinize it all — including the billions of dollars the federal government pours into the “science” — the whole things starts to smell like one festering pile of corruption.

22. The confidence game

If you’re feeling uncertain, consider that the Climate Orthodoxy has to do everything it can to pull members of the public like you into assent. Here’s one final nod to Dyson:

The public prefers to listen to scientists who give confident answers to questions and make confident predictions of what will happen as a result of human activities. So it happens that the experts who talk publicly about politically contentious questions tend to speak more clearly than they think. They make confident predictions about the future, and end up believing their own predictions. Their predictions become dogmas, which they do not question. The public is led to believe that the fashionable scientific dogmas are true, and it may sometimes happen that they are wrong. That is why heretics who question the dogmas are needed.

If you are a Climate Agnostic, that’s okay. (You won’t burn at the stake; you’ll merely burn in the heat of a baking planet.)

Postscript: We are creative conservationists

As the world changes for this reason or that, we are growing richer, stronger, smarter, and more resilient. We are becoming more conscious about the environment and its natural treasures. On almost every environmental dimension — including air quality, water quality, the extent of forestland, and the return of wildlife — things are getting better. Whether you think most of these gains are a consequence of environmental regulations or improvements in market efficiencies, one thing is clear: wealthier is healthier. We should continue to cherish the beauty of the planet and continue to grow economically so we can afford to protect its wonders. Being agnostic about climate change does not require that we stop loving Planet Earth, it only means keeping a cool head and an open mind, even when the discourse overheats.

Rendezvous with RAMA

Viscount Monckton Takes The RAMA Challenge | The Lukewarmer's Way

Yesterday I offered a set of basic statements. They are aimed at finding out where agreement stops and starts with skeptics. (My secondary motivation is to help deligitimize use of the term ‘denier’, which I despise.) The statements are:

• Global surface temperatures have warmed about 0.8C over the course of the past century or so.
• Humans have the capacity to change the climate through our actions.
• Scientists have identified ways in which human activity can change the climate: Deforestation, pollution, changes in land use / land cover and emissions of greenhouse gases.
• Conventional physics accurately describes how greenhouse gas concentrations can contribute to warming.
• Emissions of greenhouse gases have grown dramatically over the past two centuries, as have concentrations of CO2 in the atmosphere

I asked if skeptics would tell me if they agreed with these statements. So far, they do, if my comments are any indication. I’ll repeat my invitation here. Skeptics, what is your level of agreement with these statements?

I emailed them to Viscount Monckton, the UK nobleman who has been one of the leading figures of climate skepticism.

He has responded. And boy, did he respond, sending me a Word document 10 pages in length. I’ll publish his entire response in a separate post. First, though, here are his responses, his level of agreement, with the base statements above.

1. Global surface temperatures have warmed by about 0.8 K over the past century or so.

(Viscount Monckton, or VM) “Since 1900, global mean surface temperature as measured by the three longest data series – GISS, HadCRUT4, NCDC – has risen by approximately 0.9 K, a rate equivalent to 0.8 K century.” (He offers serious reservations which I show below.)

2. Humans have the capacity to change the climate through our actions.

(VM) “This statement is trivially true. Every living thing on Earth has the capacity to change the climate. Nearly every plant takes CO2 out of the atmosphere; every volcano and fire and nearly every animal adds CO2 to the atmosphere every time it breathes out. The ocean takes CO2 out of the atmosphere when it cools and adds it to the atmosphere when it warms. The greenhouse effect has been posited hypothetically, demonstrated empirically and explained theoretically. Its existence is no more in doubt than the theorem of Pythagoras. The question is whether but how much our emissions influence the climate.” (Again, more below.)

3. Scientists have identified ways in which human activity can change the climate: Deforestation, pollution, changes in land use / land cover and emissions of greenhouse gases.

(VM) “Again, the statement is trivially true, and accordingly skates neatly around the true topic of scientific debate, which is not whether the four listed activities can change the climate but to what extent they do change it.” And again, more below.

4. Conventional physics accurately describes how greenhouse gas concentrations can contribute to warming.

(VM) “Once again, the question is not expressed quantitatively and cannot, therefore, be answered definitively in scientific terms. It is trivially true that adding a greenhouse gas to an atmosphere such as ours will – all other things being equal – be expected to cause some warming. The results of Tyndall’s experiment are not up for repeal. The real scientific questions are whether all other things are equal, and how much warming a given greenhouse-gas enrichment will cause.”

5. Emissions of greenhouse gases have grown dramatically over the past two centuries, as have concentrations of CO2 in the atmosphere.

(VM) “Yet again, there is insufficient quantitative information in this statement. Yes, emissions of greenhouse gases have grown, but in what sense is the growth “dramatic”? Grown compared with when? Dramatic compared with what?”

Despite his caveats (some of which I agree with, some of which I do not), it is quite clear that Monckton is not a ‘denier’ of science. He may vigorously dispute the findings of some research and he may be right in some cases and wrong in others. I will try to add my comments to his so readers can see some of the differences between a lukewarm and a skeptic point of view.

More importantly for the future of my RAMA initiative, we can see that we don’t have to start at zero level in establishing a base for negotiating recognition of climate change. We still have to make the case–Monckton (and others) are clear on this.

As commenter Hunter remarked in yesterday’s post, “The list is more or less agreeable. The question is: To what degree? The least agreeable point is that “Conventional physics accurately describes how greenhouse gas concentrations can contribute to warming.”
-Are we dealing with “change” not definable, a term of convenience for hypesters, or “warming”, which the hypesters have largely left behind?
If it is “change”, the question like all questions regarding “change” of any sort is this: how much, and what are the good and bad impacts?
So far a rational honest look at that question has not taken place in the larger public square.
The second question is regarding the 0.8oC: So what?
Grant that this change has actually happened, and let’s posit that 100% of it was caused by human generated CO2. Where is the harm?”

But that is infinitely easier that it would have been if the Konsensus alarmists had been right about skeptics. As the Konsensus has been wrong about everything else, I am not surprised to encounter firm evidence they are wrong about skeptics as well.

Ronald Bailey Refuted On Evidence for Man-Made Climate Change?

Energy Sense from an Unlikely Source | Power Line

Energy Sense from an Unlikely Source | Power Line

 It is in a series called “Getting to Zero” (as in zero carbon emissions), written by a self-described liberal convinced about climate change disaster, and described thusly:

In this series GETTING TO ZERO we will take a very hard-headed look at current energy policy and energy strategies. We will ask hard questions: does this really get us to zero? How much would it cost? How rapidly can it be deployed? We may find some answers along the way, but don’t expect them to be easy.

We’ve all read those rosy optimistic stories about renewable energy, and how in some given month 100% of new electrical capacity in the US was all renewable; or about how during some hour in the dead of night all of the electricity demand in Denmark was met by wind. You read those stories and you think, “Hey! We’re making progress in the climate fight!”

And that impression is dead wrong.

The second installment of this series looks at the economics of renewable energy and, citing a study in the journal Energy, concludes that it really blows (so to speak). The discussion gets a bit technical at this point, with an extended discussion about EROI (energy return on investment) and “buffering” (meaning essentially backup supply for sources like wind and solar that are intermittent) along with some very interesting charts, but the author ends up concluding that wide scale adoption of renewable energy “will reduce GDP. The economy becomes less efficient as we deploy less efficient energy sources to run it.”

The discussion of wind power is especially interesting:

Wind is a tricky case. If you ask most people, they will tell you that we don’t currently have energy storage for wind. In fact we do, but the buffering for wind comes from natural gas powerplants, which are typically built at the same time wind is deployed. When the wind dies, the backup gas plants are turned on, to keep the grid power reliable. Thus the energy storage for wind is embodied in the natural gas that isn’t burned when the wind turbine is producing peak output.

This means that wind, as it’s used now in the US, isn’t really zero-fossil. It’s a hybrid system that’s part wind, part natural gas. And considering the availability of wind (30% is typical for a wind turbine), most of the energy actually comes from the fossil side of the equation. We’re using the wind to offset some of the CO2 emissions from the gas plant (which is good), but instead of getting to zero, we’re just walking toward the cliff instead of running toward it.

Denmark currently is one of the most wind-energy-intensive countries in the world, which works because they buffer their wind energy against hydroelectric power from Norway and Sweden. When the wind is blowing in Denmark, they export electricity to Sweden, which then can turn down its hydro plants (thus keeping more water stored in the reservoirs behind the dam). When the wind dies, Sweden turns up the taps on the hydroelectric production, and exports that stored energy back to Denmark. It’s a great zero-fossil system, but it’s only possible because of the unique geography that places a flat windy country right next to a couple of wet mountainous countries.

The author concludes that we need a lot more hydropower and nuclear power—both forms of energy that environmentalists hate. (In fact, most state “renewable portfolio standards” specifically exclude hydropower as an option to satisfy the RPS mandate.)

The third segment in this series looks at energy efficiency, which many greens seem to think is the magical pathway to a carbon-free future. Here the author is even more scathing:

There’s just one problem. They [the efficiency/conservation advocates] are all completely and totally wrong. Increasing energy efficiency does not, has not, and will not ever reduce overall demand for energy. This is not just an opinion; it has been demonstrated with the cold hard equations of physics, based on the second law of thermodynamics.

Now don’t get me wrong. Energy efficiency has obvious economic benefits, and those benefits are often enough to make such improvements worthwhile. It’s not that we should stop being more efficient. It’s just that we should not expect those improvements to reduce energy demand or carbon emissions. Because they won’t do that.

So what Koch-supported, flat earth, denialist site hosted these sensible reflections?

The Daily Kos.

You read that right. Here are Part I, Part II, and Part III. I’ve never heard of the author, Keith Pickering, but if he keeps this up, he’s going to get “investigated” by House Democrats for departing from the script.

A Taxonomy of Science Blogs | Watts Up With That?

A Taxonomy of Science Blogs | Watts Up With That?

What would it look like if you asked 600+ science bloggers to list up to three science blogs, other than their own, that they read on a regular basis, and then visually mapped the resulting data?





Now, you can see WUWT in yellow over on the left, almost totally isolated from the other groups of blogs, in tiny type, with only a few links to it. This raises an interesting question, which is—how could Ms. Jarreau’s results be so far from reality? I say “far from reality” because by just about any measure, Watts Up With That is at the center of the climate blogosphere. Whether you look at total page views, “bounce rate”, page views per visitor, daily time on site, Alexa rating, you name the metric, WUWT comes out an order of magnitude ahead of any other climate blog. For example, Alexa rates WUWT as the 20,839th most popular blog worldwide … while RealClimate is an order of magnitude lower down, at 217,939th among all blogs.


I’d say three things contributed to the skewed results. First, people don’t always tell the truth. Ms. HotWhopper is the obvious poster child for this. From the topics of her posts it’s obvious that she spends a whole lot of time reading WUWT … but she didn’t list it. I suspect that for some people, it’s a guilty pleasure, but that if asked, they’d say the equivalent of “I only read Playboy for the articles” …


The second reason for the skewed results is the way that news of the survey was passed around. It doesn’t appear that there was sufficient effort given to ensuring that the questionnaire was widely distributed. A better method might have been to write up a description and invitation to participate in the study, and to ask the various blogs to use it as a guest post. In any case, more thought about how to select participants is definitely indicated. Third, and in my opinion most important, there appears to have been no definition of terms, particularly as to what constitutes a “science site”. A large number of people in Lucias thread said well, HotWhopper Sou didn’t list WUWT because it’s not a science site … and according to them, the evidence for their claim that WUWT is not a science site is that often WUWT publishes studies which later turn out to be incorrect in some way, and sometimes are totally mistaken and wrong. To me, this reflects a profound misunderstanding of what makes a science site. The problem is that there are different kinds of “science sites”.


I’ll use mostly climate science sites as examples, as I’m familiar with them. One kind of science site is just a news aggregation site. The best example of this kind is Climate Depot. It just puts up links to stories about the climate with little commentary. Another kind of science site generally restricts itself to discussions of peer-reviewed science, but gives some commentary on each link. “It’s Not Rocket Science” or the Scientific American blog are examples of this category. Another kind of science site mostly deals with the original work of an individual author. Climate Audit and Isaac Held’s blog are examples of this kind of site. Then we have sites such as Lucia Liljegren’s site, or Judith Curry’s site, which reflect the individual interests of the author but which range widely over a number of subjects. Finally, we have Watts Up With That (WUWT). What makes WUWT unusual is that it is not a site that publicly discusses peer-reviewed science documents. Instead, it is a site for the public peer-review of science documents, including original work done by guest authors such as myself, and also studies which have been peer-reviewed by one of the journals.


This is a very different animal. To start with, just as happens with the secret peer review which is the usual format for the journals, not all of the papers that are reviewed will pass muster. Of course the journals don’t publish anything that doesn’t pass peer-review, they are hidden from view. But for public peer review such as goes on at WUWT, everything is visible, good, bad, and ugly. So when people complain that there are misguided or incorrect scientific claims posted at WUWT … well, doh. That’s an unavoidable part of the public peer-review game. Some of the pieces won’t make the cut. Not only that, but it is an extremely important part of the game. Knowing not only which scientific claims are wrong, but exactly why they are wrong, is perhaps more important than knowing which scientific claims are right. So yes, there is some very sketchy science that sometimes gets published and publicly peer-reviewed at WUWT … and almost invariably, it gets shot full of holes in short order. This makes WUWT more of a scientific site, not less of one. You don’t see that kind of thing happening at say RealClimate (RC) for a simple reason—such comments are invisibly and ruthlessly censored.


And that is why the Jarreau claim that RC is at the center of anything scientific is a joke. Science doesn’t censor scientific comments, and RC does censor scientific comments. You do the math. (Of course, all sites censor comments that violate blog policy, such as those that are vulgar or insulting, or wildly off-topic … but RC censors polite, on-topic, clearly scientific objections to their posts. No bueno.) As a frequent guest author, to me this pointing out of bad science is one of the most important aspects of WUWT—any mistake that I make will be identified in very short order. This has saved me immense amounts of wasted effort following blind trails … but some foolish folks think that my occasionally publishing claims that eventually turn out to be erroneous reduces the scientific value or nature of WUWT.


Nothing could be further from the truth.


Identifying errors and falsifying claims is central to science, and the only way to do so is to first publish the claims that later turn out to be wrong. As a result, Anthony has to undertake a continuous delicate balancing act. He doesn’t want to publish things that are obviously pseudo-science, but then he doesn’t want to exclude things that might be right … plus sometimes he wants to publish things that he knows are wrong simply so that their errors can be publicly identified. Does he make mistakes in the choices at times? Of course. It’s a tough job, and it is a job that no one individual could possibly be qualified to do, for a simple reason—nobody is as smart as the collective wisdom of the crowd. There’s no way to guess what errors a thousand readers might find in a piece that you or I might think is flawless. And there’s also no way to identify the odd and curious scientific claim that in a few years might be “settled science”.


So Anthony has to pick and choose, and not every choice is right … so what? Since the public falsification of bad science is essential to scientific progress, I find the idea that WUWT is not a science site because it sometimes posts shaky claims to be very parochial and short-sited. Private secret peer-review has obviously failed. In fact, many of the ridiculously bad “science” claims discussed at WUWT are peer-reviewed studies published in the most prestigious journals … but nobody can get that kind of nonsense past the kind of public peer review which is exemplified by WUWT. There are too many smart, insightful, capable people commenting on the posts for much to slip by …


So yes, WUWT does publish some obviously bad science, including obviously bad peer-reviewed science. But what some people fail to understand is, public falsification is the heart of science … and the only way to do that is to start by publishing and discussing that science, whether it is “good” or “bad”, and whether or not it’s already been peer-reviewed. In any case, those three reasons are why I think that the Jarreau results are so out of touch with reality.

10 Charts to Brighten Your Century : The Freeman : Foundation for Economic Education

Follow link to see charts.

1. There is a rape epidemic caused by rape culture.
...incidents of rape are lower than they have been in 40 years and have been reduced by more than half. It’s not clear what factors brought about such declines, but the declines should be acknowledged.
2. Police work is dangerous, so cops need military gear.
...it just isn't unusually deadly or dangerous — and it’s safer today than ever before. The data do not justify the kinds of armor, weapons, insecurity, and paranoia being displayed by police across the country.
3. Gun ownership increases violent crime.
The most remarkable statistic is that, since gun-related violence peaked in 1993, there has been an appreciable decline in gun violence ever since — all despite (or perhaps because of) significant national increases in gun ownership.
4. Concentrations of CO2 in the atmosphere will lead to catastrophic climate change.
...despite significant increases in carbon dioxide concentrations in the atmosphere, average global temperatures in the lower atmosphere have been virtually unchanged for more than 18 years.

What does this mean? At the very least, it means we should be dampening some of the climate-change hysteria, questioning the models that have predicted greater warming, and embracing a reasoned agnosticism about the issue until it’s better understood.

5. The rich are getting richer and the poor, poorer.

The truth is, the rich are getting richer and the poor are getting richer, too. In fact, globally, the poor are richer than they have ever been in human history.

But what about in the US? As columnist and professor Michael Shermer writes in Scientific American, “The top-fifth income earners in the U.S. increased their share of the national income from 43 percent in 1979 to 48 percent in 2010, and the top 1 percent increased their share of the pie from 8 percent in 1979 to 13 percent in 2010. But note what has not happened: the rest have not gotten poorer. They’ve gotten richer: the income of the other quintiles increased by 49, 37, 36 and 45 percent, respectively.”

6. The air is getting dirtier due to more cars on the road.

In the United States, there are more than twice the vehicles on the road today than in 1980. Yet, the air quality has never been better. Remember pictures of Los Angeles in the 1980s? Smog. L.A. hasn’t seen that kind of filthy pea soup since Magnum PI.

7. We’re nearing  "peak oil."

Ever heard of Julian Simon? He’s the doomslayer who suggested we take any neo-Malthusian predictions of resource depletion with a grain of salt. Indeed, he suggested that because the human mind is the “ultimate resource,” resources would never run out. As long as there is a system of prices, property, and a profit motive, people will have incentives to conserve, innovate, or substitute. So what happened to peak oil? TheShale Revolution happened, just as Simon would have predicted. (Sorry, Professor Krugman.)

8. Our infrastructure is crumbling.

During the worst of the 2008 recession, one popular meme was that the nation’s infrastructure was “crumbling.” We were all to fear falling bridges and the general pothole-ification of America. Governments used such fearmongering to justify Keynesian stimulus policies through more taxpayer-funded investment in roads and bridges. But transportation analyst David Hartgen countered that false narrative right here in the pages of The Freeman.

9. The US health system ranks low among developed countries for health outcomes.

Not so fast. When one factors out deaths due to homicide and auto fatalities, the United States shoots to number one in health outcomes along a number of dimensions. Yes, health care is expensive. Yes, it’s convoluted. Yes, it’s corrupt — and it’s all thanks to political meddling. But the US health care system is still probably among the best in the world.

10.The Public Schools Need More Funding

Each year, the schools get more resources. Another Taj Mahighschool goes up. Another football stadium gets built. Another administrator’s salary goes up. Another union boss enjoys champagne in a hot tub. And what happens to educational outcomes? Forty years on … no change.
