The great Global Warming Swindle

In summary: The climate scientists seem quite convinced, and that's good enough for me.The arguments in the film are mainly comprised of ad hominems directed at the environmental movement and of long-discredited notions.The biggest problem with the film is that all but one of the "scientists" presented in the field are not climatologists. To anyone who thinks that their arguments hold water, I issue a challenge: find one paper in a peer-reviewed journal in the last five years which disputes anthropogenic global warming. If there really is a debate in the climatology community, then it shouldn't be too hard, right?In summary, the film "The Great Global

Turbo I fully agree with you and probably everybody else here that pollution needs to be tackled urgently, I just don't think a policy of 'the end justifies the means', which seems to be the attitude of many environmentalists, is the right way to address it, especially if the 'end' is actually the wrong goal.
That is exactly how I feel. We need to use some common sense and stop the over reaction. Until people are capable of understanding historical climate changes and realistically look at the data, we will most likely cause more damage than good.

I've come to add unrecorded data. This is very raw data, I'm not analyzing it or making conclusions, but here goes:

I live in Alaska. Commercial fishing, I've witnessed 3 used-oil bonfires (probably about 10 5-gallon buckets. On land, I've witnessed probably 2 tire-burnings (piles were about five foot radius at bottom of pile) use SOC to find heighth. There's this place in my hometown that the high-schoolers always light whatever gets left out there on fire. Plastic tables, cars, and other random city installments don't ever last longer than a month.

Now, I only fished commercially for three or fours years.

Now imagine all the people doing this all over the world for the last ~70 years. Is that a significant amount of CO2 contribution? I don't know.

I think you might be underestimating the depth of a modern quantitative science. You're basically describing the level of a lower-division undergraduate. Except on very rare occaisions, graduate-level errors are culled out of papers long before even the review process begins. Just for fun, why not head over to arxiv, and pull a few modern papers at random. See if you think an undergraduate has any REAL hope of finding error, or making some kind of meaningful contribution.

Here are a few, which my mouse just clicked at random...

Yep.

The worst car polution I have ever encountered was in Bangkok. Driving around in a tuk-tuk, I really thought I was going to be asphyxiated before I got to my destination.
Hahaha. India is worse! Much worse. But in Guam I saw my cleanest air, and most polluted has the cleanest best air I've seen :smile: Except when we get those weird floating evil clouds of Chinese pollution, then you really notice. We also had a volcano eruption a few hundred miles south, then you REALLY notice. You could smell the sulfur and taste the ash in your mouth, visibility was greatly reduced and the air had kind of a slightly-brownish fog to it for a few days.

On one episode of Penn & Teller Bullsh!t, Patrick Moore (former president of Greenpeace) said that species reduction claims are nothing more than estimates and there's basically no evidence of dwindling biodiversity on this planet. The episode was about the ignorant hysteria behind the environmentalist movement.

It's possible that he too is just making stuff up, but the scientific method doesn't require you to prove innocence. If you make a claim that diversity is going down, you need to back it up with evidence. At least give a URL or something.
It seems to me species are constantly dying, and a biodiversity crisis seems like an abstract, future, false, crisis. I really don't know anything about it, but it just looks like that.

I think what you are failing to consider is that having a PHD does not mean that you cannot be DEAD WRONG or even crazy. Passing peer review does not make something correct. Having a consensus among a group of scientists does not make something correct.

The amount of "warming" that pollution by humans has added to the "natural" warming has not been proven to be causing any major climate changes, it is only a guess at this point.

Are you familiar with Atlantic Multidecadal Oscillation?

What is the AMO?

The AMO is an ongoing series of long-duration changes in the sea surface temperature of the North Atlantic Ocean, with cool and warm phases that may last for 20-40 years at a time and a difference of about 1°F between extremes. These changes are natural and have been occurring for at least the last 1,000 years.

"Is the AMO a natural phenomenon, or is it related to global warming?

Instruments have observed AMO cycles only for the last 150 years, not long enough to conclusively answer this question. However, studies of paleoclimate proxies, such as tree rings and ice cores, have shown that oscillations similar to those observed instrumentally have been occurring for at least the last millennium. This is clearly longer than modern man has been affecting climate, so the AMO is probably a natural climate oscillation. In the 20th century, the climate swings of the AMO have alternately camouflaged and exaggerated the effects of global warming, and made attribution of global warming more difficult to ascertain."

AMO neither proves nor disproves global warming. For that matter it is totally unrelated since it deals with the Atlantic Ocean only. It merely states that a one degree temperature variation of the the Atlantic ocean has been occurring for approximately one thousand years.

The frogs look to be the canary in the coal mine.

WHAT CAUSES DEFORMITIES IN FROGS: In a given population, if 5 percent or fewer of frogs have malformations, that is natural, but there are populations where 70 percent show deformities. Researchers are trying to understand what outside source is causing the frogs to develop abnormally, resulting in diminishing populations around the world. Among the factors that have been studied are climate changes, such as global warming and the thinning of the ozone layer, which can result in overexposure to ultraviolet radiation. Habitat destruction is also a factor, as is pollution: frogs absorb water directly through their skin, so they are vulnerable to water pollutants like pesticides and acid rain.

Exactly my point since the SST of the Atlantic is one of the major examples touted by GW advocates as proof of Global Warming and catastrophic climate change. I'm glad to see you agree it's not related.

What GW advocates never mention is that since SST has risen in the western North Pacific, the frequency and severity of cyclones has decreased dramatically over the last 15 years.

Sorry, but cherry picking facts like this just makes GW's lose credibilty.

Evo, are you talking about politicians or scientists? And can you include a link to an example, so we can see for ourselves how they could be so wrong? I find it hard to believe that scientists in the field can either be ignorant of things that the lay person is aware of, or alternatively, can pull off a scam of the magnitude indicated.

The point is that GW advocates were claiming that a rise is SST would equate to a rise in storm activity. Turns out that's not what is actually happening over most of the world's oceans.

Also, the cherry picking was not addressed at you.

I understand what you mean, I was just kidding a bit with the cherry picking thing.

My overall view on all of this is that it is time to move on to new and cleaner energy sources. And hopefully do it sooner rather than later. Burning fossil fuels creates a lot more than just CO2.

My personal opinion on global warming is that with all of the billions of tons of CO2 man has added to the atmosphere in the last 100 years, it would be abnormal if we didn't see some warming.

Then again we can just blame it on the sun.:smile:

Peterson would agree that the raw meterological data is non-homogeneous. That was his purpose.

When Feynman wrote about CCS, he was referring to scientists within a discipline not questioning the work of previous scientists in that discipline, often whose work they were building upon.

It is the job of scientists to question and poke at the work of other researchers in their field. This is likely to be well beyond the ability of any layperson or non-specialist, in general.

The non-romantic fact is that it is the scientists job to convince other specialists, then tell the non-specialists how it is. I can't convince a lay-person about some data regarding J/Psi suppression in QGP, I can only really tell them. I can convince a peer, however. It's the job of the other peers to make sure I'm kept honest.

His purpose was to "homogenize" the data with an assortment of ex post facto corrections; i.e., that it is homogeneous. Meteorological temperature measurements are in fact uncharacterized combinations of air temperature, wind speed, and emissivities of assorted "tattle-tale" gray bodies, none of which are included in the collection of ad hoc corrections that are applied.

Again, to be fair his purpose was to attempt to more rigorously homogenize the data. Either way, the old UHI analysis was far worse, and we're all convinced that UHI's are a temperature gradient mess.

That is not RFP's point. Its not about the other guy; the other guy is not the one most responsible for insuring I'm doing good science, its me: "... the first principle is that you must not fool yourself -- and you are are easiest person to fool."

-Very High-Energy Collisions of Hadrons, 2nd para:

Then I ask you to consider, without malice, and as I dare say Feynman would, that you don't fundamentally understand the concept yourself.

BTW, for purposes of persuasion, I think you'll find the Feynman method ala "My findings are the following... but note these many possible areas where it does not explain ... is yet unconfirmed ... conflicts with previous results..." for more effective in convincing a 'lay-person' than "the consensus on this matter is..., the debate is over..", etc.

If you understand the subject well enough, it shouldn't be too hard to explain it in simplified terms.

I am one of a very small handfull of people in the world that have the expertise that I have in technology. I sit in board meetings with the CEOs & CFOs of huge companies and at the same table are the CIOs and CTOs and IT techs and I have to simultaneously give two presentations, one technical and one non-technical. I turn to the CEO and hand him pretty colored diagrams and graphs, while handing the tech people detailed white papers. If you can't explain something equally well to peers and laymen while entertaining both, then either you don't truly understand the topic or you have a problem communicating.

My belief is that if you are employed in whatever capacity to support a particular view, than one needs to recuse themselve from such debates. ZA conflict of interest, pure and simple. In my biz, I always get suspicious when one says things like "among a handful in the world". Unless you have a cv with 100 plus pubs, its all puffery.

From the 'real world', as you call it, there are many contempory examples of scientists excelling in areas outside their speciality. To mention but a few there is of course Crick (he of DNA fame) who was a physicist who 'dabbled' in microbiology and was awarded a nobel prize in medicine and Prof Gilbert who was appointed Assistant Professor at the Department of Physics in Cambridge Uni in 1959 who won a nobel prize in chemistry in 1980 or even more recently Sir Peter Mansfield

Only up to a point. I've also done several "science fair for the public" and honestly, I hate it because often you have to tell a silly story that, by a far stretch, has something to do with the real stuff, but of which you can only understand the link when you already know the real stuff. The thing I often did was "explain the standard model to the layman" ; you can't really. The website for the public at CERN is the kind of idiocy you tell then.

However, I think that climatology must be explainable to a physicist. After all, it's physics, and relatively simple physics (only, the system is complicated). You do not need any general relativity, quantum field theory or whatever sophisticated part of the arsenal of the modern theorist to do climatology. It's essentially a complex transport phenomenon, of the kind you meet in many branches of physics and engineering: thermal transport, radiation transport, matter transport. Absorption, re-emission etc...
All this is in principle understandable by any physicist worth his degree. There shouldn't be any *theoretical* difficulty for a physicist to follow any argumentation by a climatologist. Of course, some jargon would have to be explained, several known phenomena by climatologists would have to be repeated etc... but normally, a physicist should have all the theoretical knowledge to understand a detailed argument.
Unfortunately, I haven't yet seen such an argument, completely developed from A to Z, where I don't have to take anything on faith (which I shouldn't, given that I'm able in principle to follow every argument) and which leads to a conclusion that there is or that there isn't, any GW.

Thank you! It's quite frustrating to watch some otherwise potentially valuable threads fall into a cycle of dueling citations and appeals to authority.

I used to write and present safety courses to the crews and staff responsible for the operation of Kraft chemical recovery boilers. At any given presentation, there could be low-level utility operators (including new hires), boiler operators and their assistants, evaporator operators, foremen, superintendents, engineers, etc. These boilers represent huge safety risks because they burn evaporated black liquor, and any uptick in the water content of the feed liquor could result in a smelt-water explosion capable of cracking the boiler tubes. You just don't want that happening inside a water-tube boiler operating at 900 psi or so.

The training was mandated by the mills' insurance companies for the most part, and I could have just presented the materials to satisfy the training requirements (40 hours/year for each operator, typically), but I made a point of trying to convey to each person in the room how the proper performance of THEIR job could contribute to boiler safety. Conveying the material in a way that was understandable and usable to people with such a wide range of experience/ability/responsibility was a challenge, but it was do-able because I knew the mechanics, physics and chemistry of recovery boilers inside-out, and in my previous job as a process chemist, I had worked with engineers, operators, and their supervisors in a similar environment for years. Putting in a week's worth of classroom time was pretty foreign to some of these guys, so if I couldn't keep the material relevant and interesting, I would have lost them the first day.

If I ask someone a question about some aspect of their job and they can't explain it to me, I assume that they either have a problem formulating and communicating concepts OR they don't understand what they are doing. I ran into this a lot in older mills in which Jim trained Joe and Joe trained Frank and Frank trained Larry... This peer-level on-the-job-training is dangerous in potentially risky situations like boiler operation, because without skillful evaluation and re-training, you eventually get to the point where your operators can tell you "first you open valve A, then you throttle back on valve B until this gauge gets to this level..." without any real understanding of what's going on. Sorry for going OT, here, but it seems that too often statements are made to the effect that some aspect or another of this GW debate is too complex to explain properly to the masses. That is an unacceptable way to duck a question. It's one thing to say "you are wrong" or "you don't understand the problem" - it's another thing entirely to have the depth of knowledge and understanding that will enable you to explain in clear and simple language why the other person is mistaken.

What is "The Great Global Warming Swindle"?

"The Great Global Warming Swindle" is a controversial documentary film that argues against the existence and causes of global warming. It presents alternative theories and evidence that challenge the mainstream scientific consensus on climate change.

Who made "The Great Global Warming Swindle"?

The film was made by British television producer Martin Durkin and was first broadcasted on Channel 4 in the UK in 2007.

What are the main claims made in "The Great Global Warming Swindle"?

The film claims that the rise in global temperatures is not caused by human activities, such as the burning of fossil fuels, but rather by natural factors such as solar activity. It also argues that the consequences of global warming have been exaggerated and that policies to reduce carbon emissions are unnecessary and harmful.

Is "The Great Global Warming Swindle" scientifically accurate?

Many scientists and experts have criticized the film for being misleading and inaccurate. The film cherry-picks data and misrepresents the current state of scientific knowledge on climate change. The overwhelming majority of scientific evidence supports the existence of global warming and its link to human activities.

What is the impact of "The Great Global Warming Swindle" on public perception of climate change?

The film has been widely criticized for spreading misinformation and creating confusion about the reality of climate change. It has also been used by climate change deniers to discredit the scientific consensus and delay action on reducing carbon emissions. However, it has also sparked important debates and discussions about the role of media in shaping public perception of scientific issues.
