The public debate is indeed clouded, mostly thanks to a deliberate effort from various special interests, but the scientific consensus is very clear.

As for my references/confidence, I spent 10 years of my life building dynamic computational models of stellar atmospheres with approximately the same level of complexity (I only used the small supercomputers ;-) ) and the exact same kinds of physics (obviously not in degree but in kind), so I'd say that my layman's opinion is rather informed. I could probably transition into the field of climate modelling and contribute after a year or so of acquiring specific and detailed domain knowledge as it's not all the different from what I already know. Kinda like switching from flying jets to passenger planes.

The basic physics of what and how the greenhouse effect is and works is, believe it or not, actually close to 200 years old! The experimental verification that CO2 causes the effect in Earth's atmosphere is between 120 and 150 years old depending on who you credit (the guy who suggested doing it or the guy who actually did it). That's older than evolution or electrodynamics. It's possible to calculate simple estimates (as presented in most textbooks) by pencil using basic thermodynamics. This is within the capability of science majors or very motivated AP Physics high schoolers insofar they actually learned something instead of just passing the class. Spherically symmetric computer models are at least 30 years old. My main scientific work was building an advanced version of one of those, pretty much the last generation of 1D models. Three-dimensional models appeared 15-20 years ago. I've been a "superuser" on one of those. They have been refined ever since. It's definitely not a case of this being an idea that some people came up with recently and then decided to throw a bunch of computers at it. No, the methodology and numerical modelling experience behind it is pretty damn solid.

Another way of gauging the maturity of a field and its methods is to see how many universities have a graduate program for it. It's a lot. New fields only tend to have a handful or at most a dozen in the world.
That sounds like cool stuff. Since you are relatively up on this stuff, and to save me the pain of trying to sort through 18 pages of squabbling, what would be the best online place an inquiring mind could go to see the unvarnished data that shows the prediction range across the various models out there overlaid with the most recent measured temperature data used to validate them? That is one thing I have never seen. All I've seen is the fast-slope proponents attacking isolated snippets of the modest-slope model, and vice-versa.

Apologies if it's been linked on here before.

How do you think those scientists came into agreement? I think you should read through the thread again with the comic in mind. Facts and logical reasoning have been provided. You continually refuse to acknowledge or accept them.
Are you serious ? Facts being scientists have formed a consensus. The sheep argument is not valid.
No, facts being the data and conclusions what underlies thousands of papers that have been published to form a coherent theory explaining multiple observations. The consensus stems from experts (scientists who are experts in their field---i.e. not hobby level people like me) having read these papers and 97% of them came to the same conclusion.

The cartoon is a general reference to your behavior in this thread. You can go back to page 9 of this thread to verify.

I now see you wish to discuss what science is!? Seriously?!? First, tell me whether your definition substantially differs from this? http://en.wikipedia.org/wiki/Science and in particular whether it differs from this
http://en.wikipedia.org/wiki/Science#Th ... fic_method ... because this is the method that has been used. If it wasn't there would be no way that tens of thousands of climate science papers would have gotten published in scientific journals unless you claim the existence of a massive conspiracy (see point 5 above).

I seem to recall we don't really disagree on what constitutes fact (e.g. satellite observations whose existence you deny) and what constitutes opinion (any fact you disagree with?) though, so if that still holds, I don't think we can agree on what constitutes science either.

Basically, I'll side with the conventional definition of what science is which is what climate science also follows. I'm not really interested in debating alternative definitions of science. I might have had fun with that kind of philosophical debate 20 years ago, but now I just find such rhetorical exercises rather tiresome.

Now, just so you know I am most definitely not going to spend time covering thousands of papers showing you how the conclusions you want came about. In particular, since you've even claimed that basic thermodynamical theory is just "my opinion", I'm most definitely not going to try to convince you about stuff that's textbook material in junior high.

I already tried that (check page 9). Didn't work.

That nobody else has bothered to do this or the fact that I learned my lesson doesn't mean the scientific papers don't exist. It just means that nobody here has the patience to deal with it. If you want to see how those conclusions are made, go read the papers yourself. In any case, one of the rules of science is that if you claim that "you can make up something in no time at all" well then do so and if it explains observations better, we'll use your model instead. Because we're reasonable like that.

However, so far, I have not seen anything from you but rhetoric. Basically, you're not following the principles of a debate the way I stated them above. You refuse to look at any evidence claiming it's just "viewpoints" and "opinions" or when pressed you say that "you'll have to research this" and then you never do it. I'd be really dumb to spend even 30 minutes explaining how the greenhouse effect works using basic principles knowing that your likely answer will be that that's just my "opinion".

@IlliniDave - Sure thing, the best place to start is the IPCC reports which is likely one of the most peer-reviewed publications in the world summarizing basically everything that's currently known. They come out once every 4 years and the latest one will be out in 2014.

A quick search reveals this

http://www.ipcc.ch/pdf/assessment-repor ... _FINAL.pdf

Go to Box 11.1 fig 1. (around page 7 depending on your pdf viewer). You'll be comparing the red line (theory---how well can theory model observations), the black line (observations), and the green line (forecast---how well can theory predict observations). In case you're unfamiliar with the IPCC reports, you'll note that they often put things like (likely), (very likely), (high confidence), etc. after each statements. This is actually short-hand for actual statistical tests of the statistical confidence level and translates into specific p-values (for the stat nerds out there). The key is usually found in the intro of the reports. Note that unpredictable volcanoes may change the forecast (but not the hindcast). Note that this stuff tends to come out somewhat delayed because collating predictions and writing review articles is a thoroughly thankless (albeit highly useful) job.

For more detail, read the entire pdf.

There's an older paper describing how the Hansen model from the early 1990s fared twenty years later. Not bad.

That was the quickest I could find. I'll be reading the entire report once everything is out which will happen soon if not already(?) I suggest everybody who is interested in what the science says do the same. Those who don't care about the details can just read the executive version. It's much shorter and uses bullet points for the pointyheads. For the cynical people among us, there are investment opportunities here as is always the case when anyone consistently refuse to acknowledge a better understanding (just like with the housing bubble). E.g. skeptics provide increased demand (above what they're actually worth) for beach properties that are likely to drop to zero or e.g. central valley properties that will become unproductive. Heh, it's not just some intellectual exercise. There's real money to be made ;-P ... Sorry to say, that's kinda how I see it now. I've lost any hope that humanity might come to its senses in time to make a difference, so why not just profit instead :P

The kicker with this approach though is that the GW models aren't working. If they were working then you might have a point. They aren't.

Just to clear up your little point here. This is not factual or scientific. I explained clearly previously why this is not scientific or factual. Scientists agreeing is not factual or scientific. This is not a valid argument. A valid argument would be we have analyzed this and the results conform to our understanding. This is not what is occurring at all. Consensus does not equal science. Science is factually based and there is a requirement to prove it. Currently there is no proof for GW. That is where it ends. Plenty of scientists and rational thinkers disagree with the GW hypothesis and can see the massive holes in the load of crap that is being hoisted on the ignorant public.

Lastly if some solid proof becomes available I would more than happily change my opinion. I get the impression that you guys cannot and will not. Its become something that you can't drop no matter what proof is presented to you. Imagine a scientist seeing his model wasn't working and stating well I'm not going to reassess my hypothesis. That in my opinion is poor science.
Ok, then:

(1) What is your definition of "working"? One data point conforms? 100% of data conforms to model? Something in between? Maybe 80% accurate? 95%?

(2) What is your definition of "science"? Do you have an understanding of the meaning of "peer reviewed", and if so, how would you define it? And is the concept of "peer reviewed" meaningful to your definition of "science" or not?

(3) What is your definition of "proof" in the scientific sense and how is it established? How would you deal with conflicting data points? Which ones would you pick?

Please note, I'm not interested in your bald thoughts as to what these things mean. I am interested in the sources for your understanding as to these terms -- as in "what is the bases for your thought processes?". As in standard textbooks and the like that people studying science would typically rely upon. Boring, dry stuff. Not anything the "ignorant public" would ordinarily grasp at (namely, news and political websites). Please cite them.

@jacob--Thanks, The IPCC gets a lot of criticism from the naysayers, but it still seems to be the main source of information out there. Much of that is beyond my statistics background, but the illustrations of the measured temperatures versus the model bands seems to fit the story I've been hearing from the the more sober-minded around here--that the data has been tracking the low side of the prediction continuum. It will be interesting to see what it looks like when the most recent handful of years is added.

Where I live (Southeast US) this past year the winter was easily the coldest over the last 16 years, including the longest continuous period below freezing (mayhem with frozen pipes, as houses here are not built to withstand multiple days of sub-freezing weather); and the summer the coolest (had several visits from the jet stream which usually doesn't happen at all between April and October). I don't recall a single day over 100F, which may be a first since I've been here. Not far from me they are predicting over a foot of snow this weekend. I pay a certain amount of attention to what goes on in N. Minnesota and N. Ontario. Ice has been staying on the lakes past mid-May the last couple years. But I also heard on the news recently that 2014 will go down as the hottest year on record. It's easy to see how people can get fooled into believing what their eyes see (or skin feels) while missing the larger trends across the globe.

As I mentioned above, I've got my toehold in N. Minnesota, just in case the data leaps to the high side of the predictions or worse. There's a lot of water up there, which is one of my bigger concerns about the future. The soil is shallow, but wood, fish and water are plentiful.

Climate change beliefs more influenced by long-term temperature fluctuations

"A paper by Tatyana Deryugina, a professor of finance in the College of Business, finds that longer-run local temperature fluctuations – abnormally warm or cold temperatures that last from one month up to a year – are significant predictors of beliefs about the occurrence of global warming. On the other hand, short-run temperature fluctuations – from a day up to two weeks – have no effect on those beliefs.

The finding is significant because it might help to explain how people form and update beliefs about climate change, Deryugina said."


Her study ... http://deryugina.com/Deryugina_GW_beliefs_weather.pdf


@IlliniDave--Not a comment on you in particular. I had just finished reading the article when I saw your post, so I thought you might find it interesting.

@IlliniDave - All the IPCC does is to provide a highly convenient summary. Basically, it's like the biggest review-paper in the world. Unfortunately, they only come out every several years. If I had a lot of time I would be reading through the published papers they cite instead, then the papers those papers cite, etc. Unfortunately, I no longer have university access and university publishers want $20/article these days...

I found this
http://web.archive.org/web/201003221949 ... /models-2/

This compares AR4 (that's the 2009 report) to GISS global temperatures. Now we just need someone to do this for AR5...

In any case, don't ignore the other indicators like precipitation amount/patterns, drought duration/patterns, polar ice amount/spread/breakout, ocean acidity, ...

The EPA tracks around 30 of them.
http://www.epa.gov/climatechange/science/indicators/

Here's NOAA
http://www.ncdc.noaa.gov/climate-monitoring/

The safest/least impacted areas in the US is the upper midwest (IL and up, near the lakes) and the PNW. There's a post further up this thread as far as I remember.

I just finished a piece on the role the economy played in the election. The main points in the article reminded me of this thread.

The first was the oft-stated point that the economy is recovering on paper, but people aren’t “feeling” it. They might see glimpses of a recovery, but not regular evidence of it in their day-to-day lives. The second complaint about the economy was the government’s role in the recovery. The government’s programs have helped Wall St. more than Main St, and people know it. Third, the government’s assertions that inflation is extremely low don’t always ring true when a person just paid $1 more per pound for butter or ground beef than they did a year ago. That doesn’t mean the economy isn’t improving or that the government’s numbers are incorrect. It’s just hard for the average person not to harbor a little doubt when faced with seemingly contradictory evidence in their own lives.

Those comments seem remarkably similar to comments I hear about climate change. A person isn’t automatically a “denier” just because they haven’t jumped onboard the Climate Change band wagon yet. The average, reasonable person might believe what they read about the science, but still get that niggling in the back of their mind when first-hand evidence doesn’t match their understanding of the science (like when they have to shovel snow in October). That uncertainty then mixes with a percolating distrust of the government’s role and purpose, which causes some people to wonder if proposed climate change policies are meant to help the average citizen or just feed the Big Gov’t/Wall St juggernaut. I don’t think that makes the average person dumb, or ignorant, or a candidate for the flat earth society.

I was hesitant to poke this thread with a stick again, but I feel like there’s a large group of not-quite-there-yet or as-yet-undecided people who get trod on and lumped in with the woo crowd unfairly.

OT ... I worked with a few reporters this week covering the election. It was a good education on how the journalistic process really functions in the current media environment. The stories were riddled with factual errors because the journalists were ill-informed and the process happened too fast to allow for time to correct those errors. I read/edited prepared stories from one journalist last weekend that were based on presumed outcomes. They were awful! I finally made him a cheat sheet with the 'facts' he needed to know to appropriately cover the election. He admitted he passed it around to colleagues, and has asked me to prepare another one for coverage of the upcoming amnesty announcement.

News media is not a reliable source anymore, not just on climate change but on anything. I can't say I trust government-sponsored groups any more than I trust the media though. Where does that leave me? Even with the internet, it seems like finding out factual information about any topic is harder than it should be.

This is what happens when news rooms are run for profit and nothing else. How hard is it to fact check most of this stuff? A 10 second Google query and you are basically done. Obviously, there are exceptions.

Yay, my favourite thread :-P

That "niggling in the back of their mind" because they can't match up global warming with the snow in their backyard is basically an "argument from personal incredulity" which is a fallacious kind of argument. Actually it is rarely an actual argument in their mind but more like a hunch or a feeling which is why this fallacy is so easy to fall into. Especially in these internet times when "tl;dr have opinion anyway" seems to be standard MO.

The unstated premise is:

1) I believe I'm a pretty educated/informed person(*)

And the stated premise is:

2) The scientific conclusions don't make sense to me.

Which leads to:

3) Therefore, I remain skeptical about the science.

However, this conclusion is false, if premise #1 is wrong, because just because something doesn't make sense to you personally, it doesn't mean that it doesn't make sense to people who are more informed.

E.g.

1) I have a PhD in accounting and 20 years of tax experience (subconsciously: so I must know how microbiology works too. Forsooth, I pretty much know how everything works.)
2) The theory of evolution makes no sense to me.
3) Therefore, evolution is false.

(*) Unfortunately, many if not most people believe this. Very few will readily admit their ignorance to themselves or to others. Thanks to Dunning-Kruger, the weaker the grounds for holding this premise of thinking oneself informed, the stronger it's being held.

I see this fallacy in the blog comments a lot, so it's not only in politics, but also in ERE complaints. For ERE, it's the cliche complainypants who spends 5 minutes reading a blog post and then proceed to tell me how I must have made the whole thing up because there's no way he can imagine spending so little. The complainypants will even rationalize this with consumerist examples that demonstrate his lack of imagination and understanding while remaining entirely oblivious to the fact that he just demonstrated this ignorance explicitly.

The wiki article on reason says the following:
"Reason is the capacity for consciously making sense of things, applying logic, establishing and verifying facts, and changing or justifying practices, institutions, and beliefs based on new or existing information."

This is a good and succinct definition of reason, so I'll go with that.

The only REASONABLE approach for a skeptic (who is committing the incredulity fallacy) would therefore be to educate themselves on the science OR put their trust in the scientists who have spent that time educating themselves.

That would be

1) I realize I know little about X.
2) I would like to have an informed opinion about X.
3) Therefore I should educate myself.

or

1) I realize I know little about X.
2) I would like to have an informed opinion about X.
3) Therefore I should ask someone whom I trust to be informed to give me their opinion.

However, the average person hates to educate themselves and so they're not going to do that every time they're confronted with something they don't understand.---Besides, average people think they have a pretty good understanding of most things. So this approach rarely works.

BTW: In my experience there's no such thing as an "average reasonable" person which seems to be an oxymoron at least on par with "common sense".

This leaves putting their trust in the scientists themselves. Knowing this, someone looking to make people believe that climate change is wrong can either

1) Show that it is wrong using reason.
2) Make people believe that experts can't be trusted to make an informed conclusion.

Doing (1) is pretty damn hard since X was arrived at by the scientific method which will converge on the most reasonable answer by construction. A few scientists still try to poke holes in the theory using _reason_ and that kind of skepticism, call it cientific-skepticism, is COMMENDABLE and provide a valuable scientific service.

Doing (2) turns out to be fairly easy. In fact, it is very easy to make an uninformed person mistrust an expert. As Dragline informed us above, some of the methods are tools of the trade for the lawyer profession, but even lawyers have lines they won't or aren't allowed to cross. Propaganda meisters have no such lines, so they can use all the tools in the box including lying (which lawyers aren't allowed to do). I listed the ten or so most common methods of manipulation a few messages up. This kind of skepticism, call it propaganda-skepticism, is REPREHENSIBLE and deserves to be condemned.

Generally, there aren't many "not-quite-there-yet or as-yet-undecided people" who have pursued reason by picking up a textbook or read an actual scientific review. I understand that, because it takes a lot of time to understand something as complex as climate. Those who have done so tend to stop being skeptics. Because in this case the amount of evidence is overwhelming.

On the contrary, the much more popular approach is to google some politically slanted news article or repeat an argument from (2) without verification (e.g. checking whether the graph was manipulated to change the impression of the conclusion). Essentially people are buying into/falling for the manipulation being carried out in (2) focusing on the wrong data and for the wrong reasons and being led towards the wrong conclusions. This is anti-reason. It needs to be strongly discouraged and shown for what it is.

Repeating the conditions ...
"Reason is the capacity for consciously making sense of things, applying logic, establishing and verifying facts, and changing or justifying practices, institutions, and beliefs based on new or existing information."

The requirement is

1) Adhering to the principles of logic. (E.g. if a is true and a leads to be is true, then b is true... even if we don't like b)
2) Establishing and verifying facts. (E.g. no such thing as "that's not a fact, that's just your opinion" or "I'll look at that later")
3) Changing beliefs based on new information. (E.g. no such thing as "that may be true, but I still choose not to believe in that")

This would be the foundation of a reasoned debate.

Basically, I'm not too sympathetic towards repeat offences of logical fallacies.---which is why this thread gets me so riled up. Hence, I don't accept the "I'm uninformed so therefore I'm skeptical" argument. Basically, the only reasonable stance a uninformed person is either state that they are uninformed (and abstain from judgement) OR they can side with the experts (due to the overwhelming agreement between experts). However, they can not come down on the side against the experts while being uninformed themselves. Because that is unreasonable.

Modern physics teaches us that there is more to truth than meets the eye, or more than meets the all-too-limited human mind, evolved as it was to cope with medium-size objects moving at medium speeds through medium distances in Africa. In the face of these profound and sublime mysteries, the low-grade intellectual poodling of pseudophilosophical poseurs seems unworthy of adult attention.

The conclusion "3)" is not "false". There simply is no conclusion. Going back to the original point, it's a perfectly reasonable survival strategy to remain guarded about what someone else tells you when you have potentially conflicting evidence staring you in the face (or piled in your driveway to extend jennypenny's illustration) without either 100% affirming or 100% denying what you've been told. It's just the way people are wired. When global warming crushes civilization that pattern of defining the world based on what your senses tell you will again be quite useful (more so than it may be today).

In a way this thread takes the opposite stance as the thread on elite education. Here the people that deal with the simple problems/observations at hand are ridiculed in comparison to the more "informed" Illuminati. :D

Uh oh ...

Here's the fallacy again
1) I believe I'm a pretty educated/informed person. (for most people/topics, this premise is false)
2) The scientific conclusions don't make sense to me.
3) Therefore, I remain skeptical about the science.

Now, the argument from personal incredulity fallacy shows that this conclusion is wrong because just because something doesn't make sense to you (a specific person), it doesn't mean that it doesn't make sense to people who have actually studied something in detail. It's a logical fallacy to be skeptic because you can not logically conclude that you should be skeptic just because you personally don't understand something WHEN OTHERS DO.

It's the premise of falsely believing oneself informed (perhaps from googling a few blogs or reading a news article) that leads to committing the fallacy.

Logically, 3) is not false and maybe that's what you're saying.. You're definitely right in saying that there is no conclusion because 3 doesn't logically follow from 1 and 2. Yet, many skeptics make exactly that conclusion ... "I think I'm pretty well-informed and yet I can't make sense of the conflicting evidence (despite what experts say) so I remain skeptic". That's it! Right there! See?! 8-)

The fix is to realize that one is actually not informed.

Realizing this, people will either educate themselves or listen to people who are educated. If it isn't rare it is at least dumb to just make stuff up or still hold an opinion in lieu of that. For example, the elite education thread is a battle between experts and people who have experienced a lot of elite education often going through the entire system themselves. This level of informed dissent can hardly be said to characterize this thread where people make basic physics mistakes in their counter arguments.

If you don't understand something personally, you can only reasonably remain skeptic if others don't understand it either. Because in that case nobody knows and thus skepticism is a sound strategy.

However, being skeptical about unknown-knowns (things that others know but you don't) is just silly. Even when hunting squirrels in the jungle. It's certainly not normal, nor is it reasonable behaviour.

In most other fields such skepticism doesn't happen. Few people are skeptical about whether a experimental airplanes will fly, whether a dam will hold the water it's designed to, whether a drug that a doctor says works with 95% certainty actually will work. Public attitude on climate science is rather strange in that regard. Even stranger, climate change deniers/skeptics (I'm talking lay people) outside US/UK/AU are few and far between. This alone should indicate that something screwy is going on in these three countries.

It's not that people in English speaking countries are any dumber than people in other countries. What's unique about US/UK/AU is that they unlike most other countries have been subjected to a campaign of agnotology presenting potentially conflicting evidence. Using methods as detailed above. In other words they have been manipulated into a different behaviour than the one they normally have.

Who knows? In the end, we might turn out to be the smartest. ;)


To circle back to IliniDave's point ... Is 'belief' in the science a boolean value? It's either an unequivocal yes, or you get tossed into the denier heap? Is there no tolerance for a person who is 80% confident in the science/scientists?

I should have added that I don't think this is necessarily true. There is a lot of skepticism over everything--particularly if the government has anything to do with it. I'm thinking of things like vaccines and GMOs, but there are many others.

In this thread it does seem to be that way. I'm on the record saying I believe in global warming and I believe man made C02 is a factor, just that the doom and gloom scenarios are being over-stated. I even provided evidence from the IPCC reports themselves, and I was "shouted down" by walls of links.

I would say that tolerance is proportional to how informed the person actually is. That is, not how informed the person believes they are, because as stated above, most people mistakenly believe they are quite informed which is what leads to the incredulity fallacy.

Someone who actually is informed about all existing evidence can assign a quantitative (e.g. a probability) or at least a qualitative level of confidence to a statement. There are basic statistical means of doing this and the IPCC actually does this systematically. They will make statements and qualify them like this: (robust [amount of] evidence, medium confidence [in that evidence]) indicating the the amount of evidence that underlies their conclusions as well as how strong those conclusions are. For quantitative models (the physics) they will give ranges of p-values, e.g. (between 50 and 66% likely) or (higher than 99% likely).

Conversely, someone who is uninformed can not make any statements and they certainly cannot qualify them. Any statement they make is 50/50, that is, random indicating zero information content and their confidence in any statement that does not reflect this zero information position should be set at 0%. Another way of saying this is that their signal/noise ratio is zero. They should be making statements like this: (no evidence, zero confidence).

There's no such thing as (no [amount of] evidence, high confidence [in that nonexisting evidence]). It's like dividing by zero. This is how information theory works. While theoretically possible it's hardly reasonable to have a high confidence based on a limited and vague amount of evidence, e.g. "(Uncle Jack says he heard scientists made it all up)"... except on facebook, hmm..

I think this discussion is somewhat polluted by the fact that the word skeptic (which means to look, question, and investigate ... that is engage in reasoned debate) has been co-opted by deniers (who do pretty much the opposite of reasoned debate). Hence, we need to be very specific in what we're asking.

Traditionally (based on what the word skeptic actually means rather than how it's abused), if anyone says they are skeptic I would expect them to have their noses in the books learning about energy-balance models, radiative transport, cloud reflection, model validation, etc. in order to reach a level where they can make an informed opinion.

So to answer the other question: No, belief is not boolean in theory. It's just that, in practice, most skeptics actually turn out to be quite uninformed(*). Having basically no evidence or foundation to base one's conclusion on, it doesn't make sense to ascribe any level of confidence to such conclusions. Despite this if they still make claims that run counter to the informed position, they get tossed onto the denier heap.

(*) This is demonstrated by the observation that the arguments are almost always arguments that a brief study would reveal have been answered years or even decades ago. Also simple crackpot mistakes(**).

What's so depressing about this thread is that despite its massive length, I'm so far only aware of one actual skeptic who took the effort to look and investigate.

(**) A crackpot mistake is a basic mistake that anyone with a modicum of education can easily spot but which someone who pursued knowledge without any rigour would have missed and proceeded to build an elaborate theory that contradicts the basic fact. In climate science, the most common one I know is the argument that CO2 quickly absorbs all infrared radiation leading to the false conclusion that adding more CO2 doesn't alter the energy balance after that. The person making this argument is likely familiar with radiation physics but is completely unfamiliar with fluid dynamics.

Here's another example... funny or tragic?

and for those who don't trust the scientists, you can just study the science itself. Begin here,

Here's the fallacy again
1) I believe I'm a pretty educated/informed person. (for most people/topics, this premise is false)
2) The scientific conclusions don't make sense to me.
3) Therefore, I remain skeptical about the science.
That summary is a bit of a straw man.

What's been discussed in the last half-dozen or so posts is ...

1. Where a person stands on the planet she/he observes the climate
2. What that person observes does not agree with a ubiquitous, monotonic, out-of-control warming of the planet.
3. Therefore that person is hesitant to pledge absolute belief in the reported conclusions from some of the scientific predictions concerning the climate, especially those that are more sensationalist in their slant.

That person may very well be incorrect in their skepticism, but their skepticism is not fallacious.

The same reasoning process led me to say:

1. I observe that I am happy with fewer possessions and a frugal, uncluttered life.
2. That does not agree with the consensus of what is required for success and happiness.
3. Therefore I am skeptical of the conventional wisdom regarding success and happiness.

In my way of thinking this process is substantially different from saying I don't understand it therefore I don't believe it (your fallacy). If that was the case for me, I would not believe in this forum since I do not understand BBCode. However, I see ample evidence of its existence with no contradictory evidence.

Yeah, but the difference between the two is that in the second one, you're quite informed about your own life/happiness so you're making an informed statement that disagrees with conventional wisdom. This is similar to the elite education thread.

Whereas in the first one, the person is obviously not informed about the global climate and various other indicators for the entire planet but only the weather patterns in their backyard (from which one can not make general global climate conclusions). [BTW, the reported conclusions from the scientific predictions don't actually agree with the premise 2 either but that's a minor point for this argument. See http://www.ipcc.ch/report/ar5/wg2/ for what it actually says.]

The report actually makes for rather boring reading. Sensationalism is hardly the word I'd use to describe the phrasings.

In any case, consider this

1) I feel quite well and thus conclude that I am quite healthy.
2) After running multiple tests and scans with MRI machines and blood samples, several doctors come to the conclusion that I have early stage cancer and a 30% likelihood of not having more than 6 months to live.
3) Given how I currently feel, I am hesitant to pledge absolute belief in their reported conclusions about my health, especially those sensationalist ones about my potential impending death.

Isn't it more reasonable to go with:
3b) Realizing that my feelings of well being don't reveal everything about my health (premise 1 was wrong) so I should listen to the doctors.

I think most people would go with 3b but I think that's only because the medical field hasn't been hit by a systematic campaign of misinformation. One of the reasons Ebola went out of control in West Africa was the many did believe that Ebola was part of some government conspiracy to kill people and that the people in protective suits were death squads. It wasn't the case but it took a while to acknowledge that. Now consider that some climate science conclusions actually have higher confidence levels than what's generally considered "proof" in medicine. What does that say about our beliefs [here in the US/UK/AU]?

As far as backyard climates, that is what most people have to deal with, adapt to, and survive in the present. Again, it might not be a correct conclusion in the context of planet-wide climate trends. But we were discussing some of the reasons why some reasonable people have trouble with the notion that climate Armageddon is at hand.

With your medical example, if we had an equivalent data set in the GW world (the results of hundreds of thousands or millions of previous cases) where those predictions were tested/verified and based on the posterior findings, I think people would be more inclined to accept the scientific predictions. But we have early stage data for one planet with a habitable environment/climate. So it's going to be a much more difficult sell.

For the same reasons your average person on the street does not pour through medical journals, they are not going to pour through physics journals, or collections of research abstracts. Maybe there are lessons to be learned from how the medical researchers get their findings into mainstream acceptance that the GW researchers could leverage?
