The Limits To Skepticism 1093
jamie found a long and painstaking piece up at The Economist asking and provisionally answering the question: "Does the spirit of scientific scepticism really require that I remain forever open-minded to denialist humbug until it's shown to be wrong?" The author, who is not named, spent several hours picking apart the arguments of one Willis Eschenbach, AGW denialist, who on Dec. 8 published what he called the "smoking gun" — it was supposed to prove that the adjustments climate scientists make to historical temperature records are arbitrary to the point of intentional manipulation. The conclusion: "[H]ere's my solution to this problem: this is why we have peer review. Average guys with websites can do a lot of amazing things. One thing they cannot do is reveal statistical manipulation in climate-change studies that require a PhD in a related field to understand. So for the time being, my response to any and all further 'smoking gun' claims begins with: show me the peer-reviewed journal article demonstrating the error here. Otherwise, you're a crank and this is not a story. And then I'll probably go ahead and try to investigate the claim and write a blog post about it, because that's my job. Oh, and by the way: October was the hottest month on record in Darwin, Australia."

While labeled flamebait, this is something of a problem, even in less politicized fields of science. Most scientists are earnest truth-seekers, but a minority are not, and the peer-review system is not always robust to them. I work in an area of computer science that will never make Fox News, but even in this area things are sometimes suppressed for what's hard to describe as other than political reasons. At the very least, politically unpopular positions get all sorts of extra hoops to jump through that others don't--- e.g. if you're casting doubt on a position the journal editor or one of his friends staked his career on, better expect some random made-up requirements [scienceblogs.com]. If your paper scoops a large and well-funded group's work, there's a chance it'll be rejected by one of their friends, so they get to publication first--- and their publication might coincidentally borrow a few ideas or theorems from your rejected paper.
It's not all bad, and in fact most is probably good. But there are some very rotten parts of the scientific-publishing apparatus. It doesn't help that most journals are run by for-profit companies that are a bit shady themselves (Kluwer, Springer, etc.) who have no real interest in the quality of the science they publish or how to improve it. And it doubly doesn't help that the academic rat-race has gotten increasingly cut-throat, so people feel they need to resort to dirty tricks to get/keep a job, get tenure, get grants, etc.

THIS.
Having something published in a journal is not the be-all, end-all, it does not mean that a theory is now correct one and for all time. It means it is time to start wider discussion and testing. The way science works is by trying to prove things wrong. You see phenomena in nature, and you come up with what you think is an explanation for them. You refine said explanation to the point that it makes testable predictions, the sort of thing like "If X occurs, Y will also occur," or whatever. You then set out to try and prove your theory wrong. You test those predictions. You say "Ok, well then let's try making X and see what happens, if we don't get Y, we know that we are wrong." Each time you fail to falsify your theory, you are more sure it is true.
Others join in, they re-try your experiments, make sure you didn't fuck up. They find alternate explanations and test those (well maybe Z could also cause Y, not just X). The more times that everyone tries and fails to falsify your theory, the more sure you are it is the right one. Only by repeated testing by yourself and others, only by actively trying to figure out what is wrong with your theory can you reach one that you are certain (or at least as certain as we can be) is right.
So publishing an article is NOT the last step in that, it is the first. You do some work, your write it up, you publish it. Some reviewers look at it to make sure there is nothing obviously wrong, and it then goes out to the larger community. That's when things start.

That's a common myth. You see, there are many journals. All want to grow their subscribership, increase their impact factor (the scientific journal measurement of notoriety.) They do that by publishing the most interesting research they can.
Doing research that mirrors what's already been done isn't very popular; grad students and postdocs, for example, have to clear what they're doing with their PIs. That's not likely to happen unless they've got some angle. This isn't apparent to the layman- or even someone who has "PhD" in their title, but even a minor difference in premise can be a big deal.
Identical research also doesn't get published. New, fresh, interesting research is what journals want. So while Willis thinks there's a massive groupthink, there's actually little of the kind. It may LOOK like groupthink, because on the surface, yes, there's the gross layer of widely-accepted-fact. The devil is in the details, and that's where research is taking place.
It's a special kind of arrogance to think that you can just stroll in and understand, much less analyze, a field where people dedicate years, if not decades, to their research.
the author also doesn't understand peer review (Score:5, Insightful)
The author raises good points about the dangers of over-reliance on the peer review system. It's a good system but it is not doesn't always work - crap gets through and good articles aren't published.
And neither of you understand the peer review system. It's actually a very complex system, and one full of competition on many levels.
First, there are many scientists trying to get their work published. Second, there are many journals. Third, each journal has a journal impact factor. Fourth, papers mention other papers. Fifth, journals and papers are not the only means for how scientists communicate their work or collaborate. There are conferences, groups invite speakers, etc.
A journal impact factor is a simple calculation. On average, a paper published in Nature gets X number of mentions in other journal's papers. A paper published just about anywhere else gets much less. So people want to get published in Nature, obviously. But people are also realistic, and their PIs help them with finding the right places to get published. And if you don't, you can try again. Sound research is likely to be resubmitted, often times elsewhere.
When a paper is submitted, you don't just get a "we're publishing it!" or a "DENIED!". You get questions from the reviewers, sometimes requests for more data. If it's rejected, often times it's rejected with some helpful, useful suggestions on how the reviewers feel the paper could be improved, and sometimes it's said between the lines that if you resubmit after taking some of those suggestions, you'll get the thumbs up from that reviewer.
Yes, Nature and the like are the holy grail. But many, many people don't look only in Nature. They read the journals dedicated to their little niche, because they know that sometimes good, fresh thinking doesn't make it into Nature just because so many people submit. And guess what? So are all their true colleagues. So while you don't get your name in the newspaper or a mention on the nightly news, your research still sees the light of day, and often times, with more 'useful' eyeballs. And if it's good, you impress people, they collaborate with you, present your paper at their group's internal meetings, or hell, just toss the paper across the lunchtable and say to their colleages, "you should give this a glance." It's extremely common for labs/groups to have two weekly presentations- one presentation is the work of someone inside the group, and often someone in the same group presents research OUTSIDE the group. And often, it's presented regardless of how sound it is; it's meaningful to say "here is what so-and-so found" and then show why they were wrong, or what they did badly.
Now, I'm on the outside of all of this as an IT person, but I've made many scientist-friends and their lives revolve around this stuff. "Willis" clearly doesn't understand it. The peer-reviewed journal system is complex, but also remarkably free of collusion. After all, if someone presents solid research that something widely believed to be true is not, it helps the journal because controversy sells copies, generates debate and discussion, generates mentions in other papers in other journals (hellooooo impact factor!), etc. The primary concern of a journal is not looking stupid by publishing something that isn't sound and well supported, not suppressing controversial research.
Show me a scientist who bitches and moans publicly about his anti-global-warming research not being published, and I'll show you someone whose science wasn't sound enough to cut the mustard. Every day thousands of papers are submitted to journals and rejected partially or fully, and it's not a conspiracy. It's people doing research that isn't supported enough. There is certainly a dark side, namely, reviewers who don't recuse themselves or aren't qualified to evaluate a particular paper, but that's one reason multiple reviewers are involved, and you can always submit your work to another journal.

So most of the homes that are build are insanely inefficient. Office buildings tend to be more efficient, but still not at the level of efficiency that would be possible if the codes were biased in favor of efficiency, rather than against it. E.g., I'm building a house in Vermont. The guy at the local lumber company was *aghast* when I told him I wanted 14" thick walls and R40 insulation. Nobody does that! In *Vermont*! That's just lame - there's no excuse for building an energy-inefficient house. They're more comfortable, hugely cheaper to heat and cool, and don't cost much extra to build--yes, you spend more on insulation, but you can buy a cheaper heater or chiller.
Another problem is the tragedy of the commons: nobody's willing to conserve first. So everybody buys an SUV, because everybody else is buying an SUV, and so we all need SUVs to avoid being crushed by other SUVs, or whatever. To solve this sort of mexican standoff, government regulation is actually a really effective solution. CAFE standards work. Unfortunately the anti-regulation climate of the past 30 years has prevented them from doing much good as technology has advanced--ironically, CAFE standards could have prevented the extraordinarily painful market correction that came to a head in 2008 in the auto industry, but since the auto industry lobbied so hard against it for so long, they had to be bailed out.
So sure, maybe carbon taxes aren't the right idea. Maybe there are other things we should do first. But for some reason nobody seems to be doing them.
The theory with carbon taxes is to offset them against other taxes, so that they are revenue-neutral for people who are being reasonably conservative, revenue-positive for people who are being very conservative, and revenue-negative for people who are being outright wasteful. So if you modify your behavior, carbon taxes *should* save you money. But sure, for people who aren't willing to do that, they'll suck. And consequently, they'll probably never be enacted, because nobody likes to tighten their belts. And so later on we'll all get to tighten our belts a lot, suddenly, instead of a little, steadily.

Science isn't about being fair, it isn't a case of "Well YOU explain it better than me, or accept I'm right." It is a processes for learning about the natural world, and for separating what works from what doesn't. Showing something doesn't work is an important part of science. Ideally you'd be able to present a theory that doesn't but that's not always the case.
Cold fusion was a good example. Group claimed to do cold fusion, other labs falsified their research, since their experiments were not repeatable. None of those labs provided a theory for working cold fusion, none had to. All they did was show that this particular theory was wrong.

It's the dramatic hysteria and propaganda that you hear outside of the peer reviewed journals that really gets to me. The idea that if we don't stop emitting CO2 the oceans will rise, flooding out ocean front cities. There is no peer reviewed article proving that, quite the opposite, actually.
When you read peer reviewed articles, scientists are careful to put in qualifications and caveats, as they should. What I object to is the propaganda that comes after that fact, ie: "CO2 is a positive radiative forcing component (verified fact)..........therefore if we keep adding CO2 to the atmosphere the results will be disastrous (wild conjecture)." Carefully watch what politicians say when they start talking. Very often they will start with something that is verified in a scientific way, then extrapolate in ways that no good scientist would dare to do. The fact is, global warming as presented in scientific journals is not nearly as disastrous as the event presented in the news.
In a way it reminds me of Y2K. At the time I would read articles in journals like Communications of the ACM, studying how much it would cost to fix various things, and estimating the number of computers that might have issues. Then I would look at the news and hear predictions of power plants exploding and airplanes crashing and wild unrest. At some point there was a disconnect between the science and the propaganda.

Most of the anti-AGW crowd is simply doing armchair, a-priori reasoning behind why AGW is false. "Humans are too puny to have an effect!" they say, or "The climate has changed drastically fast even without humanity being around!" Often there are political reasons for holding this position--certain arguments on how to deal with GW are certainly political in nature, and may come into conflict with one's own dogma, and thus psychologically one may be predisposed to oppose GW on that basis.
HOWEVER, that does not mean that some people that argue for AGW do not fit into the same shoes. Remember, just because you are "correct" does not mean your reasoning is. Naturally, someone that hates big business and "the man" may also psychologically have a reason to believe in AGW--another reason to rage on about the status quo.
If I was a betting man I'd bet for AGW, but really I know the science behind it is quite complicated and I know I'm nowhere near competent to make a good, solid argument on the matter, so I must approach the issue with a tempered agnosticism while leaning a bit towards the AGW side because that's the verdict by a vast majority of hard-working PhDs, and I highly doubt that climatologists consist of some dark, left-wing communist sect of economy-destroying conspirators. That is what true skepticism is, noncommitance (particularly emotionally) to a position particularly when you are not an expert on it. Many on both sides of the GW debate are not skeptics but reactionaries with their thought ruled by political underpinnings.

The only arguments I've heard from the (usually conservative) anti-global-warming crowd are absurd. They fall into two main points as far as I can tell -- one is "It's anti-capitalist" and the other is "Government has no business telling private companies what to do."
In fact this is perfectly illustrated by the above post, who says
How is that "natural"? How does that even remotely follow?
"It's anti-capitalist" is just ridiculous. As an example, say we want to reduce emissions and stop using coal, so let's use nuclear. Where do they think the nuclear plants are going to come from? Someone is going to have to build, staff, and maintain those, and sell the resulting energy at profit. There are thousands of potential jobs just from the construction alone.
Someone has to design, manufacture, install, and maintain the smokestack scrubbers. Someone has to design, manufacture, and upkeep new and more efficient engines. Or solar panels, or hydroelectric power stations, or whatever. All creating jobs, all being done at profit.
There's a whole green industry waiting in the wings to do these things. How on earth is it anti-capitalist, anti-business, or anti-"The Man" to see a need for better and more efficient service, and provide that need at profit?!
"Government has no business telling private companies what to do." I don't get this one either. Private industry would never regulate itself in consideration of anything but its bottom line. There's a reason we're not all still working 14 hour days and dealing with child labor -- and it's not because corporations voluntarily relaxed those standards. Why does anyone think it's a good idea for companies to crap all over everything, dump any pollutants they want anywhere they like? But the second someone suggests that maybe that's not good, out comes Fox News and their ilk to blame government for ruining everyone's fun.
Finally, I don't see how anyone can argue that we can continue to take billions of tons of carbon-based fuel, set it on fire, release whatever combustion byproducts into the atmosphere.. and absolutely nothing bad will happen. So, again, even if it's not having any actual effect on the global temperature, wouldn't we all be better off not breathing that crap?
Can we please stop with the "denialist" crap? (Score:5, Insightful)
It really does weaken the position of those who support the AGW theory. Why? Because it is name calling and over simplification. Pretending that everyone who doesn't agree with you is simply in denial of what is happening and then making up a cute little label is not the sort of thing that speaks to a rational debate. It is the kind of thing a con man would do, and thus makes people wonder, why would you use those tactics?
So as a start, you have to understand that there are some major differences in terms of what people believe who are skeptical of the AGW thing. These are just some examples:
1) There are people who believe the whole thing is a crock, there is no warming, it is all made up, etc, etc. These are the only people who could be called in denial, by any stretch of the imagination.
2) There are people who believe that there has been a warming trend recently, however the trend is entirely natural. It is right in line with the kind of trends seen historically, and thus there is no cause to believe this is anything but a natural occurrence. They are skeptical that humans are contributing in any significant fashion.
3) There are people who believe that there is warming, and indeed man is contributing to it, but that the result will not be problematic, and perhaps beneficial. They do not accept the conclusion that the warming will lead to catastrophe, even though they do accept that humans are at least partly causing it. They are skeptical that a warmer Earth will be bad for humans.
4) There are people who believe that people are causing the warming, and that it will lead to worse conditions, but that it would be even worse to attempt to stop it. They believe that the money spent on trying to stop such a thing could be better spent on other things to improve human life. The sort of thing that while warming might cause X additional deaths per year, spending money on that instead of other things would lead to 5X additional deaths per year. They are skeptical that the proposed solutions are the best.
5) There are people who believe that people are causing the arming and that it needs to be stopped, but that reducing output won't do that. We need a different solution like geoengineering or something. Reducing CO2 output wouldn't help, at least not enough to matter, so we've got to find another solution. They are skeptical that the proposed solutions would do anything.
6) There are people who believe that people are causing the warming, and that it will be bad, but there is fuck-all we can do about it. We are too far along, shit is going to happen anyhow, so we might as well apply our energies and money to surviving the change, not to trying to prevent it, since that it impossible. They are skeptical anything can be done at all, other than to try and survive the change.
So a big part of the problem with trying to frame everyone as a "denialist" is the simplification of the argument, to try and say "Oh they all just ignore everything that is said." No, in fact, many don't. They simply come to a different conclusion. Also they may well find enough evidence to sustain part of the argument, but not all of it. You find people who say "Sure, I'll buy the world is getting warmer. We've got pretty good instrumental data on that. However I'm not so sure about CO2 being the cause. The data on that is more shaky. Either way I'm really skeptical that a warmer Earth will be a bad thing, there's essentially no data to support that." They aren't just saying "La la la, I can't hear you!" They are just not convinced by all the arguments.
Well, when you simply dismiss them as a "denialist" and act as though they are a moron, that does nothing to convert them. In fact, it may do the opposite. They say "Hmmm, this is the kind of thing con men do. When someone questions them, they just attack and shout down their questioner. They are afraid of scrutiny. They want you to accept what they say, unquestioningly. Why are AGW proponents acting like this? Could they be con men?"
So seriously, knock it off with the label. You are doing nothing to help.

Nothing, ever, is entirely certain in science. Even "laws" are constantly tested and retested.
"Sea level rise under warming is inevitable. Thermal expansion would continue for many centuries after GHG concentrations have stabilised, for any of the stabilisation levels assessed, causing an eventual sea level rise much larger than projected for the 21st century (Table 5.1). If GHG and aerosol concentrations had been stabilised at year 2000 levels, thermal expansion alone would be expected to lead to further sea level rise of 0.3 to 0.8m. The eventual contributions from Greenland ice sheet loss could be several metres, and larger than from thermal expansion, should warming in excess of 1.9 to 4.6C above pre-industrial be sustained over many centuries" (p. 67).

Many natural systems, on all continents and in some oceans, are being affected by regional climate changes. Observed changes in many physical and biological systems are consistent with warming. As a result of the uptake of anthropogenic CO2 since 1750, the acidity of the surface ocean has increased. {WGI 5.4, WGII 1.3}
Global total annual anthropogenic GHG emissions, weighted by their 100-year GWPs, have grown by 70% between 1970 and 2004.

I'll make the reasonable assumption that you are pretty intelligent, and evidently you are of skeptical disposition. Have you ever read any papers on climate science? How about earth science? If not, as would be the case for most intelligent non-climate-scientists (not just not just non-scientists), I can say without insulting your intelligence that you have no direct basis for determining what the general thrust of the literature is, much less what the camps are, who populates them and how strong the relative arguments are within those camps.
Unless you've read the literature, this statement, too is presumptive. What it really means is that one or more intermediaries has told you this, and you believe that intermediary more than you believe another intermediary who thinks that most climate scientists are in agreement. So in this case, this entire argument comes down to trust in intermediaries. You don't know who the camps are and who really subscribes to what camp.
I did a "terminal masters" in ocean physics, so I have some direct familiarity with the literature, though certainly not as deep as if I were practicing in this field. My experience is that the camps lean much more towards accepting general consensus about the nature of climate change (largely anthropogenic) and the magnitude of the expected effects than the perception you describe. From what I know directly and from the intermediaries I use when I don't know directly, just about everyone in the climate science community now believes that the arguments around concentrations of carbon and warming are solid. So when people say how much warming will happen in a hundred years, that considered very hard to dispute. Where people have more critiques is how we will get there, and the closer in you get the less agreement there is. However, it's also true that for most of the really wide open questions about climate change, people have been equally wrong guessing towards faster and slower warming. The rapid melting of the Greenland ice sheet is a great example of this - nobody from the global climate modelers (like a friend of mine who's doing his postdoc in this now) to the ice physicists understood until a few years back that when the ice sheets began to melt that the meltwater would lubricate the rock upon which the sheets are sitting and cause them to slide more quickly into the ocean. So there's an example where change was called slower. On the other hand, if I understand correctly, there has been a greater uptake of heat by the oceans that was initially expected, which will delay warming on a scale of years to decades, but could result in acceleration once the oceans warm up and provide less capacity to capture heat. So that's a delay in warming.
This statement is also full of presumption. Look at the sales of vitamins, herbal supplements and other non-FDA-approved quasi-drugs. Those sales speak to a large body of people who do feel comfortable taking remedies that are not scientifically tested. Again I challenge you to show me your basis for concluding that they're "green nuts" - sure sounds like your impression more than any data to me.

If a funded project disproved existing theory, it is up to peer reviewed journals to publish or not.
A common criticism of the system is that it encourages a sort of orthodoxy in research. So if the NSF things "dark matter" is a great explanation, then projects which try to find alternative explanations may receive less funding because it is viewed as a waste.

That is very well said. The bottom line is that if I became King of the World and had to make decisions affecting the environment, I really only have three choices:
1. Become an expert myself. This is totally impractical because it takes too long and I have a huge range of other responsibilities.
2. Listen to lots of random people and make decisions based on which things I hear sound right. The upside is that I will hear an extremely diverse set of opinions and that the best option will likely be submitted to me. The downside is that many of the opinions are baseless claims by crackpots or people with selfish interests.
3. Listen to the opinions of experts whose sole job is to study and test these issues. Baseless ideas will not pass this filter and so I will be presented with a narrower range of views, but the best options should still be present. The major issue here is making sure the experts are really experts and that they have no other axe to grind.
Of these options, it seems like 3 is the most reasonable option and that is what our current peer review process is. It is always reasonable to question the expertise of the experts, but that same questioning should be targetted at random bloggers, too.

I think there is actually a very easy way to solve this problem...show us the code. Give out ALL the raw data, every little scrap, along with the source code for the programs they are using to manipulate it.
While that may sound great, it's not always possible, or even legal. There are WMO rules, for example, that prohibit the sharing of certain data. That's why, for example, there are some major hurricane models whose results are publicly available but whose data is not available. I think it's stupid, but it is the case.
Beyond such barriers, there's also the issue that many of the scientists who have been resisting FOI requests had initially been abiding by them. There seems to be a perception in the scientific community that certain people are filing FOI requests deliberately to waste their time in order to stifle research. Or worse. You need to keep in mind that most of the people filing the FOI requests are ideological foes of the scientists they're submitting requests for, since almost all climate scientists accept AGW. So, for example, one denier (a financial trader named Douglas Keenan who considers himself an amateur climate scientist) submitted a FOI request for the data on a paper authored by Phil Jones and Wei-Chyung Wang, which Jones complied with. Keenan "discovered fakery" in the paper and tried to get Wang arrested. The university invested and cleared Wang of any wrongdoing, but the damage was already done. Is it any surprise that Jones started trying to find excuses to duck FOI requests in the future?

WTF The Economist's editorial staff doesn't understand math?
Having looked at that paper and the text surrounding the formula, I wouldn't say that I understand it and I almost certainly have a better math background than the editors at The Economist. It isn't that the formula is incomprehensible; it isn't. The formula is pretty straightforward, but that doesn't mean it is easy to understand. There are not many people on the planet qualified to judge the suitability of the formula for calculating temperature trends. The Economist is making the claim that the climate-change sceptic Willis Eschenbach is not one of those people and that seems like a reasonable claim. Eschenbach is claiming, with no basis, that the formula is an arbitrary adjustment to force a desired trend. The Economist article is stating that until a peer-reviewed journal publishes a paper that backs Eschenbach's claim, it just isn't worth the time fighting over this.

NONE of the data has been erased. Here's a quote [eenews.net]:
The research unit has deleted less than 5 percent of its original station data from its database because the stations had several discontinuities or were affected by urbanization trends, Jones said.
"When you're looking at climate data, you don't want stations that are showing urban warming trends," Jones said, "so we've taken them out." Most of the stations for which data was removed are located in areas where there were already dense monitoring networks, he added. "We rarely removed a station in a data-sparse region of the world."
Refuting CEI's claims of data-destruction, Jones said, "We haven't destroyed anything. The data is still there -- you can still get these stations from the [NOAA] National Climatic Data Center."
In other words, the guys at CRU deleted the junk which they didn't think was worth keeping. But since their data came from external sources, all of the original data is STILL AVAILABLE. Of course, you won't hear about that at the usual denier blogs, since it's just so much easier to keep your flock bleeting in ignorance when you can say "OMFG, DEY DELETED DA DAT0RZ!!!!".

Yes, CO2 is a greenhouse gas. However, its effects decrease logarithmically - the change from 0 to 20ppm make a huge difference. From 20 to 80ppm a lot happens as well. From 280 to 380 ... not so much.

Regarding "sky rocketing" levels of CO2, quite the opposite. We're in a very CO2-starved environment compared to the majority of the time plants and animals have existed on the earth.

Re:Proof by assertion (Score:5, Informative)
Perhaps it's time to once again point out that "scientific proof" is a red herring. As any number of science's theoreticians have carefully explained over the years, scientific methods rarely if ever actually "prove" anything. Rather, science works mostly with a double-negative approach: An accepted theory is one that we have failed to disprove. Scientific testing and data collection is mostly aimed at showing that a hypothesis is wrong. Results that agree with a hypothesis are generally called "support", not "proof", because usually the tests can't provide proof. But a single (correctly done;-) test or observation is often sufficient to disprove a theory.
This is why scientific theories are often called "tentative". Scientists are always trying to think of new ways to test a theory, and sometimes they succeed in finding situations where a theory fails. The poster child for this was the failure of Newton's mechanics to explain a number of anomalous observations about a century ago, which led to Einstein's theories explaining how the universe actually works. Of course, his theories have never been "proved", either. They have merely withstood hundreds of new experimental tests. Tomorrow some physicist (or high-school student) may produce a new test that demos an exception to Einstein's equations. But until then, they are accepted not because we've proved them, but rather because we have repeatedly failed to disprove them.
Of course, fundamental physics is "easier" that climate in an obvious way. Weather is much more complex than things like particle physics or orbital mechanics, which can be reduced to some fairly simple equations (though not quite as simple as we thought back in Newton's day). Anything dealing with weather has to be treated statistically, since the complexity is far beyond the capacity of our most powerful super-computers. (Our computers can't even model a butterfly's wings in detail, much less the effect the butterfly has on weather halfway around the world.;-) Since the public is generally totally ignorant of statistics, it's not surprising that people would fail to understand what the AGW theorists are telling us. It's fairly obvious that even most of the posters here in this "nerd" community don't understand the difference between weather and climate. You don't have much of a chance of understanding the issue without a good grounding in statistical methods, in addition to all the kinds of chemistry that you have to understand.
But the constant use of forms of the words "prove" and "proof" in regard to scientific theories should be treated with humor, since such words are an open statement that the author doesn't know much at all about scientific methods. Those are media and propaganda terms; they have very little use in scientific discussions. Proofs are what mathematicians do. Scientists do disproofs. (And it is interesting how well the radically different approaches of math and science complement each other. So far I haven't read much enlightening from either camp on this topic, just the observation that they play well together. But we all know that.)

Except, the burden of proof is not on the skeptics. It is on those who wish to prove the exception to the rule is, indeed, the rule. If you want people to believe in global warming's existence, you've got to prove it, irrefutably.
Considering the history of climate prediction (lies, 180 degree inaccuracy, etc.), anyone trying to do that has a hard job ahead of them. We've been hearing "we're 10 years from total annihilation due to our abuse of the planet" since my parents were in grade school, and I've got kids of grade school age now, myself. Climatic temperatures were supposed to be 20 degrees hotter now than they are and agriculture will shortly become unsustainable for the population's feeding, according to what I remember being 'taught' when I was in grade school.
That's a lot to fight against. Generations of people are tired of the propagandized rhetoric and general bullshit.
If you want people to believe you - intelligent, discerning, capable people - the first thing you have to do is not treat them like idiots. That's something the climate change community (if there is one) needs to get right. The second thing they should concentrate on is not appealing to emotion (alarmist dramatization and unqualified exaggeration) but to intellect. (Look how far it's gotten the theory of evolution.)
Another big issue which is getting in the way of people "believing" in climate change/global warming/global cooling/global atmospheric sequestering/whatever is that they're concerned about the political and economic implications of anything pushed down from governments, on account of the climate change fear mongering. Anyone who (here in the US) has had to deal extensively with the EPA knows what I'm talking about. The government doesn't tend to fix the problem at hand, they just make business-as-usual more expensive. Trade embargoes on Chinese tires? Great, tires just got more expensive. Tax fuel so people drive less? Great, you just made maintaining one's lifestyle more expensive. (And, in many, many cases, just ruined the livelihood of many others - never mind lifestyle.)
What I am personally concerned about is the reactionary uh anacrophytes - people who seem terrified of old things. They're trying to push new, (scientifically) untried, short-term, ecologically destructive, and largely infeasible technologies such as ethanol, battery-powered automobiles, wind turbines, et cetera. Yes, there is value in expanding these technologies, increasing their efficiency, and so on. But these anachrophytes are vicious in their pursuits, and want regulations, new laws, and the like which will drastically and destructively change the economic landscape. These are the kinds of people who blather on about the "smog" that diesel engines put out, how they maintain our energy dependence - why they aren't a viable alternative to gas - yet they push things like lithium based batteries as "green". Which planet are they on?
And now we've got this environmental summit which, optimistically, will push forth changes that will cut down on emissions/etc. Realistically, it will be another splint on the otherwise healthy leg of the US and Western countries, allowing for China and the rest of Greater India, and the third world to push closer to us - economically and militarily.
In the best of times, such "optimistic" regulations are mildly disruptive and inconvenient to a society - at best. But these aren't the best of times; these are pretty tough times for everyone, globally. So even in a best-case scenario, we're looking at what might be generally termed, a bad idea. Struggling economies aren't terribly good at ecological preservation: they'll burn waste oil for heat, dump shit in streams, and so on. Damaging an economy for the pursuit of reducing CO2 output is ass-backwards if one has any perspective on how economies work.
So yeah, prove me wrong. The ball is in your court, but you're a long way behind in the game due to decades of slacking/misbehavior.

Well before Watt's stared his website scientists had already explained how adjustments are made to compensate for the urban heat island effect [noaa.gov] but that didn't stop our pluckly little weatherman from building a website to show those ivory tower dwellers where they were sorely mistaken. As Watts fame (and income) grew, NOAA thought it might be a good idea to try and add some clarity so they took 70 weather stations that Watt's himself had rated as the best. They re-ran their analysis with just those stations and compared the result to the original analyisis using all 1200+ stations. Lo and behold the two curves were virtually identical as can be seen on the first graph in NOAA's response to Watts [noaa.gov]. Why? - Because the trend does not rely on the abolute temprature, it relies on the changes in temprature. Such systematic errors in measurement have long been known and handled by mathematicians and scientists alike.
Observant readers may note that a fully qualified political scientist by the name of McIntyre did manage to get a paper on the subject published in an obscure journal which was subsequently hyped so much that the US senate held an inqusition (err, inquiry) into Mann's 1997 hockey stick paper.
The inquisition called on the US National Acedemies of Science to proffer an opinion on McIntyre's claims. Their testimony [nationalacademies.org] came down heavily in favour of Mann's conclusions but also made some minor crticisims of his confidence levels. Mann being the leading scientists he is took those critcisims seriously and subsequently published an extended study in the journal Science, yes that's right, the world renowned journal published by the very same organisation who critcised his confidence levels.
McIntyre's paper failed to stand the test of time but rather than having another crack at science he went off to become yet another fully qualified blogger and created the popular front site "climate Audit", I say front site because both Watt's are McIntyre are stongly associated with the anti-science lobbyists at the CEI and the Heartland Institute (now there's a couple of targets for an email hack if I ever saw one).
McIntyre used his site to continue pushing the claim that Mann had hidden his data (where have we heard that before?). To put it politely, I am highly skeptical of that claim. If it was true then how did NAS come to it's conclusions in their testimony, and how is it that many others have also replicated Mann's work? Why is it that both Watts and McIntrye take selective quotes from the testimony to loudly declare that they "discredited Mann's hockey stick"? - You would think that if the testimony actually came to that conclusion then they would want you to read it. Yet nowhere on either site will you find an link to the testimony because...well...skeptical people might actually go and read it.
Considering the above farcical chain of events I don't blame Mann for expressing his desire to keep McIntyre's discredited paper out of the IPCC reports, I would have said the same thing. However this does not change the fact that the paper was subsequently included and discussed.
For those who don't like to read scientific papers and abhore pdf's there is an excellent summary on the youtube channel Climate crock of the week [youtube.com], unsurprisingly Watt's abused the DCMA in an attempt to have the video removed.
