26 Common Climate Myths Debunked 998

holy_calamity writes to mention that New Scientist is revealing the truth behind the '26 most common climate myths' used to muddy the waters in this ongoing heated debate. "Our planet's climate is anything but simple. All kinds of factors influence it, from massive events on the Sun to the growth of microscopic creatures in the oceans, and there are subtle interactions between many of these factors. Yet despite all the complexities, a firm and ever-growing body of evidence points to a clear picture: the world is warming, this warming is due to human activity increasing levels of greenhouse gases in the atmosphere, and if emissions continue unabated the warming will too, with increasingly serious consequences."

    I'm a firm believer in verifying scientific claims, especially when they are used to drive policy on a global scale. I just think that a) the topic has been played out, and b) Climate change discussions on slashdot have moved from discussing the science behind it to silly flame wars (I know so, because I pretty much started one the last time around).

    I seriously would like to put a moratorium on these stories until there are some new and credible theories that come up. Relinking to the same old arguments (both ways) does nothing to advance the discussion, or the knowledge of the topic.

    You've said there that there's a known *localised* cycle, and that the ice is thicker because of it. What are you saying about global climate change, exactly? As far as I can see, all you're saying is that it's not as strong in that one location as the ice cycle.

    And not all change is bad. Yes, we should do something about pollution of all sorts. A clever observer will notice though that warmer climate equals more arable land at a time when there are more humans to feed than ever. Opportunities abound.

    I could not disagree more. I am thankful to New Scientist for compiling this handy reference list, because I can pull the debunkings from it out whenever someone says something stupid instead of having to write about it, track down references, etc.

    Until the danger is gone, there will still be work to be done.

    Education is the first step. Granted, some people paid so little attention in their high school physics class that they are completely unable to have any kind of rational, reasonable discussion on the subject, but my solution is to euthanize them and move on :D

    Yes, the earth has been much warmer in the past. When the dinosaurs roamed the earth, for example. However, they didn't have up to a billion people living within a meter of sea-level.
    It really doesn't take much melting of currently land-bourne ice to cause massive displacement problems for a lot of people. Look at a map of your country. See how many of the major cities are coastal ports.
    Were it not for the very expensive Thames Barrier, London would already have ended up like New Orleans at a couple of points. It may well still be over-run this century.

    Don't worry what may happen to most of the coastal cities. I'm sure you live well away from the sea. Shame so much trade, and thus the global economy runs through them.

    Having spent many hours arguing with people who will jump on any conspiracy theory they can find, and who will happily trust a 2 hour program on channel 4 instead of a plethora of peer reviewed scientific journals, I don't know if I should laugh or cry at the posts in this thread. Lets get this straight once and for all, you will not debunk anything with two sentences. Simply explaining what global average temperature is, or what is meant with a greenhouse gas, or what radiative forcing refers to, requires an entire article on its own. I don't know how many times I have seen some statement along the lines of "Solar radiation changes" completely ignoring matter of relative magnitude, time-scales, research on the topic, and whatnot. At the end of the day the issue is so complex that the only one-liner that has even the slightest legitimacy is "this is what the vast majority of experts on the topic believe" and even that one requires credible references ( as so many sceptics will contest it ). Anyway, the most useful bit of text that will appear in this entire thread follows: http://en.wikipedia.org/wiki/Global_warming [wikipedia.org] There you go, it isn't perfect but it is the best that will appear on slashdot.

    The scientific community isn't bickering about the basic things: that warming is occuring, and that human activity is contributing to it. The "the scientific community is divided so there's nothing we can do" line is just used to prevent action.

    and that is, There are many many variables to the causes of global warming and you cannot pin it on one variable.

    I hear so many times from folks, especially in the media, that the planet is warming because of 'X'. They always want to blame it on one thing. My favorite is that "the Sun is getting hotter! It's not the human race!" Or others love to blame the SUVs or coal fired power plants exclusively.

    What I'm getting at is the folks who reduce the argument to one variable, regardless of your point of view on the matter, are muddying matters even more and making is difficult to get folks on board to solve the problem. So by saying, "the Sun is getting hotter." tha just gives people the rational to throw their hands up and say "There's nothing I can do.

    My wife had a great answer to a neighbor who believes that global warming is myth. She said to him, "By taking the steps to reduce greenhouse gases that cause global warming, we will be cleaning up the air. And I don't know about you, but I like clean air."

    Here in Metro Atlanta, most of the Summer is "Smog Alert Day" and it's miserable. Everybody, pro or con, wants clean air - even the global warming naysayers.

    At risk of getting modded down for saying something unpopular:

    ALL data on climate change is anecdotal. There is only one earth! There is no sample set to compare to. The causal inseparability of the weather across the earth prevents you from testing lots of cases except over very long periods of time, which hasn't happened since forming the latest consensus model.

    Yes, that sucks. No, please don't mod me down for pointing this out.

    I agree that it is a handy reference list - just like about a million others there. It's nice though that it comes from a source whose main goal is not related to Global Climate Change. And yes, discussion and education about the basic principles influencing climates is important.

    However, in the context of slashdot, I haven't seen a new argument in about a year, with the lone exception being perhaps the impact of interstellar radiation on cloud formation. It seems the people left arguing against Global Climate Change simply refuse to even consider the possibility that they might be wrong. The old saw about leading a horse to water comes to mind.

    Then again, I guess I could also just ignore the articles. :)

    I'm going to avoid the flame wars. I ask a simple question.

    To "debunk" a myth, one takes a superstitious opinion and replaces it with provable fact. When I clicked under "warmging might be great" link or whatever, this is what I got:

    As global temperature climbs to 3C above present levels - which is likely to happen before the end of this century if greenhouse emissions continue unabated - the consequences will become increasingly severe. More than a third of species face extinction. Agricultural yields will start to fall in many parts of the world. Millions of people will be at risk from coastal flooding. Heatwaves, droughts, floods and wildfires will take an ever greater toll.


    Now I'm obviously a moron for questioning such great scientists as the ones that put together this report, so I'll play AC. My question is where is the fact in the above paragraph? IPCC says liklihood of 1 degree rise in next century. We have some circumstantial measurements about what a 3-degree change _might_ do, but can scientists really predict this much catastrophe THIS FAR OUT IN THE FUTURE?

    I call bullshit. To address my call, please provide a demonstration that your theory can provide measurable, repeatable results. Make a prediction for 20 years from now. If you get it right, by golly, you have what is called in this neck of the woods science. If you start waving your hands around and claiming doom is nigh and we don't have time for such silliness, then I call double-bullshit. Matter of fact, looks like triple-dog-bullshit to be exact.

    Reading just one of them...

    Climate myths: They predicted global cooling in the 1970s
    "Indeed they did. At least, a handful of scientific papers discussed the possibility of a new ice age at some point in the future..."
    "This scenario was seen as plausible by many other scientists"
    "However, Schneider soon realised he had overestimated the cooling effect of aerosol pollution and underestimated the effect of CO2, meaning warming was more likely than cooling in the long run. In his review of a 1977 book "

    Ok... so remind me how this is a "myth" again? Scientists did predict global cooling in the early seventies, and the idea caught on. The fact that someone disagreed near the end of the seventies doesn't eliminate the fact that they did believe it would happen in the early seventies.

    There's a lot that can be said about climate change, but that article was not it. I was disappointed in that publication. The most eggregious error from a computer science perspective is that it requires no great talent to train a model that predicts your training data, and even your withheld data, and still have the model prove worthless when confronted with unknowns from the real world.

    I read articles every week about major new terms being proposed or incorporated into these models, I hold about as much faith in these models as chess computers from 1980 that regard castling through check as a legal move. Three decades later, the progress with chess programs is a wonder to behold. Our present climate models are perhaps good enough to suggest strong grounds for concern, but looking back 30 years from now, they'll seem like toys.

    I'm sure I'm not the only one who's sick of hearing the scientific community continually bicker amongst themselves.
    Hate to break it to you, but that's how science works. We propose ideas, we attack each other's ideas. We argue. We refine our ideas to take into account the weaknesses others have pointed out. This process is iterative, and eventually generates more robust conclusions... often robust enough to make predictions, or even to guide social policy in an intelligent way.

    I'm sorry if it sounds like bickering to you. You are most welcome to not listen if you don't like it (and to not read Slashdot stories on topics you are now bored by), but if you want science to continue progressing then accept that the scientific community will be in a constant state of debate. That's a good thing, by the way.

    And if you're waiting for "irrefutable proof" and "cure-all solutions" on *any* topic (much less climatology) then you may as well just give up on scientific inquiry entirely. There is no such thing as irrefutable proof, and no such thing as a cure-all solution without drawbacks.

    The problem with "peer review" is the "peers". If the individuals doing the review have a bias, the approved, reviewed information will reflect that bias.

    I don't aggree with Gore's "case closed" statment. I think human activity has an effect on the climate, anybody who thinks we have no effect is either ignorant or a fool. However, I don't know that we are the determining factor. We simply don't have enough information yet. There is a LOUD chorus of individuals who claim to be sure, and they drown our the scientists that say we need more study.

    I am WAY more worried about more serious pollutants. We are pumping materials many times more toxic than CO2 into the air and water. I think we will face problems like rising cancer rates, mutations and sterility that will effect us decades before this minor (yes, minor) climate change.

    But I also hate the frakking heat.

  • Shrug. Looking through this thread, there are a bunch of obviously over-emotional "there is no global warming people", and they all either make the argument that, "90% of the scientists in the world are wrong because of *insert anecdote here*" or that the whole thing is completely political and manufactured by the liberal media.

    You at least bothered to make some citations, but the citations you made are irrelevant...Drudge talking about the weather? Jim Inhofe's blog? That bastard is so conservative he doesn't believe in fire, and he sure as hell doesn't know the first thing about science.

    Now take the article that is the point of this thread...It's on New Scientist, which is at least scientific in nature (unlike either of your examples), and each point is made with citations to sites that also deal in science, some of which are quite reputable.

    Given those arguments, who would you believe if you didn't have an obvious bias?

    It's when talking points are either flat out wrong or just drastically miss the point that problems arise, and that's what we see with most global warming denialist ones.

    You say that, and ignore the summary that cites, "this warming is due to human activity increasing levels of greenhouse gases in the atmosphere" ... ? is due to

    That absolute tone - stating that there is no other contributing factor, and that only humans have anything to do with climate change - not only flies in the face of countless other observations (and just plain common sense), but it's the sort of smug, one-dimensional, fear-mongering assertion that tends to bring out the opposing talking points you're so annoyed by. If you don't like simplistic counter-fire, why aren't you combatting the real provocation for them, which is unadulterated crap like that gross and misleading simplification? Not long ago we were in an ice age. Things have changes a lot since then. Man did not do it. Man's activity could well be an important contributor to the nature of, or impact of ages old cycles and other influences. But "it's man, and that's that" is a deliberate bit of trolling and the foundation for political power grabbing.
  • Think of it like snopes. "They predicted global cooling" if by "they" you mean a handful of scientists, and by "predicted" you mean in an unspecified future. Usually, the people posting this want you to infer that "they" refers to a scientific consensus, and "predicted" means "soon". Yes, certain magazines totally got this wrong. So, in the sense that the poster usual means when they say "They predicted global cooling", it is not true.

    I don't know why you find it so hard to believe, except that you're clinging to your interpretation. Global CO2 levels are higher than they have ever been, as far as we can tell. We put out more CO2 than volcanoes do on average and we do it without releasing non-black particulates to mitigate the effects.

    But actually, if you just start reading through those articles, every point you have raised has been well-explained there. The only problem with their publishing this information is that it just won't do any good if you can't convince people to read it.

    New scientist publishes an article "debunking" global warming scepticism in which they say it's a "myth" that polar bear numbers are not declining. They claim polar bear numbers really are declining.

    A sceptic points to another article about reliable research that found polar bear numbers are rising in at least one specific (and very large) area.

    True believer claims "we can't know for certain either way", it's still possible numbers are declining in other areas.

    How do you know about what is happening now is almost as bad as a comet? Were you around at that time? Yes we have fossils, but fossils don't tell the complete story and I wish people would understand this. What fossils tell is a probability of something that maybe happened based on interpretation. Its like the Bible. Did it happen, probably, but did it happen how people recounted it? Probably not.

    The problem I have with many of these theories is that they attempt to extrapolate to situations that we experience everyday, which is a major mistake. Here is my reason why the dinosaurs died. The reason why the dinosaurs died is because the aliens that kept feeding them left the planet. Don't believe me, right? But am I wrong? You ask where is the proof that there were aliens?

    Proof is interesting because until recently we thought Columbus was the first European to reach North America, now we know it was the Vikings, and if you read Farley Mowat he even says it was earlier and not the vikings. There is even a theory that the first Europeans came to North American during the Ice Age and they think this due to the genetic imprints of the Native North Americans.

    My point is that we don't even know the exact truth 5000 years ago. History has this odd behavior to become lost and found again. Constructive mostly unbiased history started about 40 years ago. Everything before that was selective information. And now you are telling me, something that happened 65 million years ago is similar to today? Yeah right, maybe it did, maybe it didn't and unless you can say "I was there" everything any scientist says is a formal form of handwaving.

    I, for one, welcome our new scientist myth-debunking overlords.

    I enjoy my re-education and only wish to serve the greater good of mankind, as defined by those who know more than I do.

    I reject calls for understanding that science is about observation, theory, and reproducible results. Instead, I whole-heartedly accept that science is about consensus, caring for others, and saving the planet. As a computer expert, I give up my knowledge that computer models are almost pointless when dealing with ten-thousand variable systems and accept that scientists know what is important and what is not.I reject my selfish way of wanting to keep my rich lifestle. I understand that sacrifices must be made, mostly by me, in order for the poor to survive. I gladly give up my wealth to those central managers who will take my resources and apply them where they make the most scientific sense.

    Gosh. I feel so much better! This was a lot more fun than surrendering to the last overlords. Now that I've joined, do I get a brown uniform and a cool set of black leather boots? Is there a cool hand salute or anything?

    Apologies if I appear cynical in any fashion. I am sure some more re-education will fix me right up. We unwashed masses are in constant need of education.

    The problem is that "global warming skepticism" already has developed into a fully-fledged pseudoscience, in the same league as creationism, astrology, homeopathy, crystal healing, etc., etc., etc.

    The core characteristic of a pseudoscience is that is carefully constructed to weave its way around the facts, and that is highly adaptable: Like a nasty disease, it will rapidly develop resistance to any argument used against it. Also, it is inherently unfalsifiable, because a pseudoscience is not a theory that can be used to generate predictions that can be tested (as a science should be), but a collection of objections and statements of ignorance that does not make predictions. Science predicts. Pseudoscience only objects.

    It is important to understand that distinction. If a scientific theory predicts, say, a temperature of 23C, and the measurement is 12+/-3C, then that theory cannot be correct -- it has been falsified, as Karl Popper argued. But if a pseudoscience claims that something cannot be right because the temperature is 23C, and you react by showing data showing that it actually is 12+/-3C, then that fails to destroy the pseudoscience, because that was just one of the potentially infinite number of objections that constitute the body of the pseudoscience. You can, therefore, spent an infinite amount of time carrying on counter-arguments.

    So although I applaud New Scientist for making the effort, sadly, it is a complete illusion that this will convince anyone. You cannot convince people who have already made up their mind to ignore factual arguments, by using factual arguments. As tempting as it can be to enter such a debate, I have to warn that almost every possible way to spend your time and energy is more rewarding and more fun. Most science students make that error sooner or later. Most will learn that it is just a pointless waste of time. Much better to work on the real scientific case, and ignore the loonies.

    My excuses for the 0.001% of climate change skeptics who are actually using a scientifically valid argumentation. I regret that they are getting the dog's fleas by involuntary association, but they still have their colleagues to find intelligent conversation and solace, even if they may not agree.

    And at the end of the day, it probably won't matter that much. I am confident that the majority of people is sane, and that democratic government will (slowly but with some inevitability) result in an acceptable policy. There may be some hold-outs, but in those cases there is always Sarkozy's suggestion of taxing the exports of countries that don't address global warming.

    But science doesn't come in leaps and bounds. Every tree ring or ice core that is analyzed either adds or detracts from the credibility of a theory. Every run of a computer model aims at matching it up a little bit better with the historical record. The science on climate change has ever-so-slowly morphed from the "global cooling" theories of the 1970's to the much more accurate computer models of today. We have much more data and a much better understanding of climate, and even a better understanding of what we don't know. To claim that we are still arguing the same science today as we were even 10 years ago is disingenuous... 10 years ago there were enough holes in the data to ask serious questions about the whole theory. Today, people still keep asking the same questions even though they've been answered pretty well.

    I'm sorry, but you are unlikely to get a "new and credible" theory, since the only 3 possibilities are that man-made CO2 increases global temperature, decreases global temperature, or has no effect on global temperature. All three have already been posited, and only the increasing temperature theory has a substantial amount of evidence to support it. Your comment is proof that we need to continue to talk about it.

    However, global warming fanatics scare the hell out of me.

    There is no CONCLUSIVE evidence for either side. However, if I have to choose between siding with scientists from MIT or Oxford - or "scientists" that got project grants or paid jobs because they mentioned "Global Warming" in their project name - guess what I'll choose...

    A lot of trading in the financial markets is already carried out by computers. Many base their decisions on fairly simple algorithms designed to exploit tiny profit margins, but others rely on more sophisticated long-term models.

    Major financial institutions are investing huge amounts in automated trading systems, the proportion of trading carried out by computers is growing rapidly and some individuals have made a fortune from them. The smart money is being bet on computer models.


    There's a huge distinction between using software to handle stock trades and using software to model the stock market. The author blurs this distinction.

    A very large hedge fund tried modeling the market in the 90's. Hired a bunch of analysts and some Nobel prize winning economists to create the models. Bottom line - the fund went belly up. Almost took the rest of the market with it. (See Cramer's "Confessions of A Street Addict" for details. Note: it was not Cramer's fund). The stock market is too large, complex, and chaotic a system to accurately forecast.

    The problem is the evidence for warming does seem to be selective. Everything "hotter" supposedly proves global warming (or anything colder, or anything unusual in any way), but any example to the contrary "doesn't disprove anything". Okay, if any one counter-example doesn't disprove it, then any one example doesn't prove it, either. It's just as foolish to ignore all of either type of example just because any single example doesn't carry much weight.

    Global warming is a hysteria similar to the Y2K hysteria, it is propaganda that is created for the same reason: money. How much money was made on the believe of the world that the civilization will be destroyed because in the 2000 due to the computer bugs?
    If your goal is to refute the concept of global warming you may have possibly picked the absolute worst possible example. The reason Y2K was a fizzle and not a bang is precisely because all of that money was spent on work to retrofit the world's computer systems.

    The professional community had been worrying about and working on fixes for Y2K for more than a decade prior. It was only as the deadline approached that the general public got a hold of the issue. Of course the companies that had procrastinated until the last minute were forced to pay outrageous sums of money to get their systems fixed - the engineering adage of "Fast, Good, Cheap - pick any two" was in full force and "fast" was a requirement.

    The only problem with their publishing this information is that it just won't do any good if you can't convince people to read it.

    And the REASON you can't get people to read it is that it tends to be introduced with summary notions that imply: "The weather would be perfectly stable, and very pleasant, and nothing would ever, ever change, and there would be unicorns bringing us nice books to read under the light of their sweet, sweet rainbows if it weren't for Americans and their cars, which also happen to be painted ugly colors." Climate has been, and always will be all over the place, in terms of trends and even huge ugly swings. We certainly are contributing some to the current state of affairs. If we were all living in loin cloths in villages of a hundred people, though, the climate would still be very different today that it was 25,000 years ago. And 100,000 years ago. The Sahara used to be bigger, and hotter than it is now... perhaps because there was a lull in paleolithic SUV driving or something, who knows.

    Even if global warming is just fear mongering there are still good things that can come from that. For the first time companies are getting enough pressure and consumer interest to build fuel efficient cars and explore new fuel sources. In the last few years there have been more advances in solar, wind energy then there have in a long time. As an added bonus if we find a renewable energy we can finally stop relying on the East for oil. Something that has been fueling wars for the last 20 years. We could finally find more economic independence. Which would be great. If Global Warming is the catalyst for this change than I welcome it with open arms.

    A lot of these "debunkings" aren't even that. For instance, the one trying to debunk the rising temperature of Mars just says the "evidence is sketchy." Well, yeah, the evidence for global warming here on Earth is sketchy too, which is why politicians use terms like "following the fingerprints" in describing the correlative, indirect conclusion that the rise of industry has risen the temperature. In fact, April's temperatures were cooler than average according to a report released today, and 2006 was the least active hurricane season in decades despite dire predictions to the contrary. Climate is unpredictable, folks. The rest of that particular debunking is just some sketchy explanations without any proof, like "it could be regional cooling."

    Another one claiming to debunk that we predicted global cooling in the 1970s doesn't actually debunk it at all. In fact, it admits that many scientific papers indeed predicted it. Then it goes on to explain why they were wrong. How does that debunk it? If anything, it bolsters the argument ("If they were wrong then..."). The best part is the way it ends, by claiming THIS time they're right because TODAY's scientists say different. Why are they different from the scientists of the 1970s?

    Look, whenever there's a claim of a consensus in science, run for the hills, because that is never true in science. There are plenty of top scientists who don't believe in the current Hysteria-O'-The-Year that's driving the current news cycle for ratings. When in doubt, follow the money, because there is money to be made in ineffective carbon credits, dangerous mercury light bulbs, and higher taxes. The current hysteria will be mocked in the same way "new Ice Age" fears of the 1970s are now mocked.

    In 15 years, absolutely nothing will have happened, and we will be completely fine, and the media (which is a business) will have its journalists (employees) reporting on whatever news cycle is driving revenues that year. In 2007, global warming is driving revenues. When it stops driving revenues, it will disappear from the front pages.

    What does that have to do with what I said?

    Let me see if I can say it another way.

    If I said, "Those anti-smoking Nazis think smoking kills you. But what about George Burns -- he smoked all the time, and lived to be 100."

    you would wisely reply, "That's just anecdotal. If you look at the set of all people who smoked as often as he did, you see, on average, very low life expectancies."

    Now, look at climate change. The GGGP said (adding comic flair) "[Those GW nuts think the planet's getting warmer. But look at Canada -- it's just the opposite.]" [1]

    you can't say, "That's just anecdotal. If you look at the set of ALL industrialized terran planets in which greedy capitalists mercilessly dump CO2 into the atmosphere, they're hot as hell.[2]"

    [1] Yes, I'm simplifying. Global climate change is what they really complain about, which could include a colder Canada. But as long as the earth's weather is tightly coupled and there exist possible situations that could contradict such predictions, the same principle applies.

    [2] I mean hell in the secular sense.

    However, I don't know that we are the determining factor. We simply don't have enough information yet. There is a LOUD chorus of individuals who claim to be sure, and they drown our the scientists that say we need more study.

    I agree completely; however I don't think that means it's ok to not do anything. There is a lot of evidence that we are an important factor. It's not obviously a closed case, and it does need more study, but we also need to avoid the trap of "paralysis through analysis." We can commission study after study and await results until it is either too late or the costs of fixing it have gone up. At this point, the evidence is strong enough that it should be clear we are better off starting to solve the problem *now*, while continuing to study it, than we are postponing a solution while the problem gets harder to solve in hopes that we've been wrong.

    Put another way, "needs more study" vs "fix the problem" is a false dichotomy -- there is nothing to say we can't start solving the problem now, while it's still tractable, while *also* continuing to study it to make sure both that we're solving the problem in the best manner and that it actually exists / is solvable.

    For example, the 'myth' on chaotic systems - the whole definition of chaotic system is that if you have two very similar sets of input data, you can get two very different sets of dissimilar outputs - so using the kind of prediction that the global trend in a chaotic system will remain the same is bullshit.

    This should probably be Myth #0.

    Thermal noise is the symptom of molecular movement being a chaotic system. That hasn't stopped people from developing statistical mechanics and thermodynamics which, ask any mechanical engineer, are still highly deterministic and useful with sufficiently large sample sets. While weather is a chaotic system, and localized climate is relatively unpredictable, the average behaviour of the Earth's system as a whole is much more predictable.

    How, exactly, is an article that goes into the science behind a given issue over the course of several pages a "talking point"?
    More accurately, it is a "reference" that sums up the current state of peer-reviewed literature.
  • The point is, that climate change is happening at a much faster rate than it has in the past. You're right, it will get warmer or cooler - eventually. The point that you're missing is that it actually matters how quickly that happens. If it happens slowly enough, people and animals can adapt.

    So you're saying that less than a 1% increase in production of CO2 is enough to change the climate this much? Even with the fact that tropospheric water vapor has an order of magnitude greater effect on thermal regulation? Sorry, but knowing how effects like this pile up suggests strongly to me that the people producing these articles are pushing a pet theory. All the people screaming about warming seem to be the same ones that hate any big industry. These arguments come off as alarmist, when most of these folks agree that we'll all be dead by the time anything significant happens (if it happens at all, as a trend I've noticed is a constant downward revision of the expected impact, starting from the mid 1980s).

    Sorry, it's just not enough. Furthermore, you're suggesting that a reduction of less than 1% of CO2 emissions will cool the planet? Ugh. Hey, you do know that the Earth is physically too far from Sol to maintain it's temperature without an atmosphere? It'd be really easy for us all to freeze to death. In fact, IIRC one of the worst ice ages actually got so cold at the poles that the researchers who discovered it feared that the temperature could actually drop low enough to allow CO2 to precipitate out of the air. At which point, the planet would probably freeze solid, at least at the surface, irreversibly.

Warmer temperatures cause ocean currents to change, which in turn affects global wind patterns, weather, temperatures (causing both warmer regions to be colder, and vice versa).

    Normally, yes. However, the presence of so many heat sources in one area that is created by high density cities means that the local microclimate changes fundamentally and so pre and post-civilised weather (not climate, note) records are essentally useless to compare. Note London's frequent 5 degree increase on the temp of the surrounding countryside, for instance. Hence me pointing out that local weather records would only really be useful as far back as the city goes. Note he did say city, not area.

    Not every scientist who says "no" to human-driven change is employed by the oil industry.

    Not every scientist who believes climate change is occuring, believes it is man-driven.

    Take a look a look at this list [senate.gov] of significant scientists that are now abandoning the "man-driven" idea. Some even say they felt pressured to lend their voice to the "man-driven" cause because that was the side their bread was buttered on.

    I'll add to this. Starting to fix the problem now is a decent idea. But we need more than just that - we need technology to fix the problem. Some of that technology is presently being developed, some of it is entering the mainstream, and some is still a long ways off.

    I've heard it said that changing the climate is like steering an aircraft carrier, only a whole lot slower. The main thing I would have people consider is that panicking about the state of the atmosphere is counterproductive, and that's the biggest thing I'd complain about as a "climate myth". We are not working against some sort of impending carbon countdown doomsday clock to doom and oblivion. We're just making the climate slowly, but measurably and somewhat predictably, worse, over the coming decades.

    Certainly we want to do something about this. But what we don't need are radical, crazy things to change the course of things: it's disruptive, and won't work. We need strong measures, but they need to be flexible, and they need to give people time to adapt. Real change takes time - much longer than anyone with a political stick to shake can hope for to boost their career. You probably can't change your driving habits overnight. You probably can't go out and buy a new super-fuel-efficient Prius at the drop of a hat. (If you can, you have too much money.) Industry needs time too. I have an acquaintance who is a power plant engineer. The new plant coming online in several years' time is basically some sort of gypsum factory, or something like that (probably not actually gypsum, but I've forgotten what it was) that also happens to produce electricity. It puts out very little carbon into the atmosphere. But a power plant takes a long time to build - decades.

    Of course, I think many people, and many good environmentalists, realize this. But the current state of affairs isn't a state of Good Environmentalism. It's a state of Moral Panic, of pseudoenvironmentalists chanting the "Bush-Republicans-and-Industry-are-Evil" mantra, and politicians giving handouts instead of promoting real change (*cough cough* I'm looking at you, Ethanol - and also some of the stupider handouts to industry for E85 engines that never actually see a drop of the corn squeezings). What we need isn't, as Tony Blair put it, "radical international measures" because you can't possibly hope to cut global emissions in half overnight, short of global thermonuclear war. What we need a good dose of Truth, and not just what Al Gore thinks of it. We need reasonable measures. I'm sick of the hackneyed, black-and-white, us-versus-them approach to The Environment we have today. The world needs real solutions, not career-boosting buzzwords and political propaganda.

    Then if it ever comes to that, they can move to an industrialized country (like mine), get a non-subsistence-farming job, and live a lot better.

    Ugh. I can't tell you how sick I am of this innummerate argument. I thought Slashdotters were supposed to understand math.

    So you're saying that less than a 1% increase in production of CO2 is enough to change the climate this much?

    Here are some made up numbers to illustrate the point:

    Every year, natural sources put 200 units of CO2 into the atmosphere, and natural sinks pull 200 units out of the atmosphere. The net change in atmospheric CO2 concentration is zero. (In reality, it's not zero, but it's a small and random fluctuation compared to the actual upward trend of ~35% since pre-industrial times.)

    Along come humans, who put 2 units of CO2 into the atmosphere every year. Natural sinks pull 1 units out of the air, leaving 1 to accumulate in the air and raise total CO2 concentrations. After a number of years, those units accumulate to something large.

    What is important is not the change in production, but the change in amount left in the air. The change in CO2 concentration is, as I said, about 35%, not 1%.

    Even with the fact that tropospheric water vapor has an order of magnitude greater effect on thermal regulation?

    Again, this is the wrong number. Water vapor and other greenhouse gases warm the planet by ~30 degrees C, explaining why the Earth is not a frozen iceball (as you yourself note). The increase in CO2 since pre-industrial times has added an extra ~0.5-1 degree of warming to that baseline. That warming is small compared to the 30 degrees provided naturally by other greenhouse gases, but it is responsible for most of the actual observed warming (about 1 degree) which has taken place.

    (Also, CO2-induced warming creates more water vapor which itself amplifies the warming trend in a positive feedback.)

    In fact, IIRC one of the worst ice ages actually got so cold at the poles that the researchers who discovered it feared that the temperature could actually drop low enough to allow CO2 to precipitate out of the air. At which point, the planet would probably freeze solid, at least at the surface, irreversibly.
    I don't know if that is right, but let's take that statement at face value.

    If a 100% decrease in CO2 concentration is enough to permanently freeze solid the entire planet, is it that hard to imagine that a 35% increase in CO2 (from 280 to 380 ppm) can cause a single degree of global warming?

    There is no "evil" from a earth point of view. From a human being point of view however that's another matter.

    - There could be change in habitable area, resulting in necessary population displacement and probably a lot of dead.
    - There could be change in local climate resulting in variation of vegetation and animal meaning there will be famine. That means there will also be migration of diseases and parasites. For example, tropical diseases in the UK.
    - Last time there was such a big warming there was also a massive extinction of animal(see TFA): the time evolution does its job and repopulate earth. Unfortunately human being will have to live in the meanwhile. ( For example in Europe, a lot of plant relies on the frost to clear the parasites. Without frost, that means the ecosystem will change a lot )

    That enough to say that in case of real climate change humanity will enter a chaotic period with a lot of death and misery. Even the US and Europe will be impacted since they rely a lot on the poorest nations - and chaos is not good for business anyway.

    That said, sure maybe a better humanity will emerge but I would rather live in the current one without a SUV.

    If someone could CONCLUSIVLY prove that humans are the sole cause of global warming, and that global warming is not natural, and that it is bad, I would listen.
    Actually, only that last clause needs to be proven. By your reasoning, an asteroid hitting the earth is nothing to be worried about because humans wouldn't be the cause and it is a natural process. If global warming is bad, then we should work to reverse it regardless of its cause. Some proposed solutions assume that CO2 increases are the cause and work to remove CO2 from the atmosphere, but other solutions involve reducing the about of solar radiation absorbed by the earth (via microsats or changes to planetary albedo).

    If you read the whole article and contemplate it as a whole, you will find that it says our emissions (e.g. what we put into the air via cars and other "emissions") are indeed lower than natural emissions, but that humans are also responsible for increasing natural emissions by, e.g., deforestation and other means.

    The real problem isn't the "is global warming happening" debate.

    The real debate should be, "ok, what can we do about it?" And, remember, one of the options should be "nothing."

    Once that's been discussed, we need to move on to, "ok, what do we do about it?" And, again, remember that "nothing" is an option.

    All I know is that a lot of the energy saving tips the media frequently puts out: http://news.bbc.co.uk/1/hi/magazine/6636521.stm [bbc.co.uk] are idiotic. Partly because many of them are unworkable (how much power does turning off your broadband connection really save? Seriously? I could run my home router for a year on the power my water heater uses in half an hour.) But mostly because they don't know how generating capacity works... we need enough generators online for peak load, regardless of whether your broadband router is turned off or not. As long as all those generators are running to meet peak load, you're burning the exact same amount of fuel and releasing the exact same amount of carbon.

    Figure out how to ACTUALLY slow down the release of carbon (hint: nuclear power does it) and I'll be happy to follow your stupid tips. But as long as you're asking me to unplug my router which won't make a whit of difference except to annoy me, then it's just not going to happen.

    (Oh, also, stop being pissy to people who already do more than most to reduce pollution. Every morning I ride a train to work; you tell some people this and they say "wow, those diesel locomotives put out a lot of pollution." Oh yeah, sorry, me and the other 400 people who ride it should all drive our cars instead, thank you Mr. Genius Environmentalist.)

    No! Despite the fact that we all heard about it on TV, the radio, newspapers, and magazines, and even though they taught it in every elementary school's earth science curriculum, it didn't really happen.

    That one statement alone - that global cooling was never really widely believed - is enough to make me write off anything else a source has to say. I was there and it happened, and I don't care how much some people wish that it hadn't.



    Its not that it was never widely believed, it was that it was never a scientific consensus the way global warming is, and thus is not a parallel.

    Saying we shouldn't pay attention to the broad scientific consensus on global warming because of a popular media craze in the 1970s around a prediction made by a handful of scientists which many others found merely plausible is, well, rather spurious.

    So, yes, "they predicted global cooling, but now they predict is global warming" is a myth. More precisely, it is equivocation. The "they" that predicted global cooling aren't the same "they" that predicts global warming.

    I have lived in a desert all my life. Normally, this time of year every day is full of sunshine with not a cloud in sight. But this year, more than any other, it is cloudy, cool and rainy (this is really really strange). Who is to say that global warming won't actually increase rainfall in some areas? There is more water because the water from the polar ice caps are melting. There is more surface area for the water to evaporate from since the tide is rising. On a global level, it is warmer, so there should be more evaporation. Thus it is possible for it to rain more in these areas saving lives.

    Obviously, I am no expert. But I am extremely skeptical of these "experts". I can see how they can trend global climate change...but rainfall predictions in certain areas? Give me a break, we can predict that two weeks out with very much accuracy.

    Quite frankly, the climate is always changing regardless of what we do. Should we try to do less to pollute...absolutely. Is global warming a huge deal. Not as much as people are trying to make it out. We have less effect than people want to believe. In fact, a few decades ago scientists were predicting global cooling. And if the climate was always stable...explain the ice age.

    People like you make me sick. If you are so worried about people dieing than give up your house, your car, your friends, your spouse, and move to those countries with the extremely poor and work to help them. Just because you right some self-righteous post on Slashdot doesn't mean you are any better than the people who like cool A/C and watch Fox News. What the heck does that mean anyways? Does CNN give off less greenhouse emissions.

    This has nothing to do with politics for me. I can't stand the current administration and am a registered Democrat. I think Fox News is so horribly skewed to the right that it can only be viewed for entertainment purposes. My objection to the global warming hype is that it just doesn't make sense. They are only presenting one side of the picture and they are doing in a way that is wrong. Just like Bush uses the fear of terroists to win votes, it seems like these people are now trying to use the fear of global climate change to push their agenda. I suggest you try actually reading the counter-opinions instead of just reading the stuff that says the same thing. There are intelligent people who are unbiased that think this is overblown. At one time most scientists thought the sun revolved around the earth. Scientists are not always right...no many how big a herd of them there are.

    The problem by labeling "global warming skepticism" as a pseudoscience means that you have already shut off the ability to listen to any counter views (no matter how valid or scientifically sound). No one doubts you can provide evidience that there is a warming trend. But the climate is not something that is stable. It is always going to be doing something. So for a short peroid of time in the history of the world (and I mean really short) it has been getting warmer. Could this be due to human's? Absolutely. But there are 1000s of other factors as well. I used to be firmly in your camp...but after looking at the hysteria about this and reading some counter views...I am under the impression that you guys are overreacting. I believe that a lot of people are just going along with it to decrease our pollution rather than being scientifically honest. It takes a lot to get the public to care about something that will inconvienince them.

    And just for fun, try looking at this from the other side. Look at the enviromentalists as the ones presenting the pseudoscience. After all, they are biased as well. When the global temperature next year actually is a little cooler...will you be so ready to throw out the belief that we are headed for disaster (and that we are solely responsible for it)?

    Where a bunch of people who have only a vauge idea of what it even means to qualify as "science" or "proven" argue with research done by experts in the field because a letter to the editor they skimmed in Readers Digest while waiting for the Dentist said "Global warming is a bunch of hipe".

    Any dissenters please prepend your objection with:

    • Citations from respectable science journals (you can't find many, they simply don't exist...yeah, it's that much of a professional consensus)
    • Your qualifications, e.g. education and/or experience. You don't have to be a climatologist, but something better then a high school education or liberal arts degree would help. Other wise you most likely don't understand the above citations.

    Of course, this is where you say "well who the fuck are YOU?". Well, I'm just a lowly computer engineer who tends to side with the experts in the field and the volumunous amount of research indicating we are experiencing abnormal temperature increases caused by man and primarily his entry into the industrial age.

    Thing is, if you disagree with the experts but you a) are not an expert and b) do not have the proven skills to comprehend the experts, then c) you don't think you believe gobal warming isn't happening. Yes, I just called you ignorant if you don't meet the above qualifications. I can do that. I'm on slashdot.

    "The science on climate change has ever-so-slowly morphed from the "global cooling" theories of the 1970's to the much more accurate computer models of today."
    Yeah, that's right they changed because the science changed. They changed because the temperatures stopped falling. In the 1970's the recorded temperatures had been falling since the end of WWII. In the late 70's or early 80's that stopped and temperatures started to rise. Did this lead the alarmists who had been yelling that Man was bringing on a new Ice Age to re-evaluate their assumptions? No, they just changed from predicting an Ice Age to predicting disastrous increases in temperature and that as a result we needed the government to take over everything. The same prescription to solve a different problem.
    When I see that Al Gore (the prophet of Global Warming) using more electricity in a month in one of his multiple houses than the average American uses in a year, I become somewhat skeptical about whether he really believes what he is preaching. In addition, many of the other proponents of Global Warming exhibit similar inconsistency. if the spokespeople for Global Warming aren't concerned enough about it to sacrifice why should I be?

    "We know today how to stop increasing levels of CO2 in the atmosphere. If the situation was really as dire as articles like this seem to pretend it is, and if the outcomes were known to the level they would like us to believe, there would be no reason not to turn the switch off."

    Knowing how to top increasing levels is very different from actually being able to do it. The long term solution is conceptually easy but practically difficult. All we have to do is stop dumping greenhouse gases into out atmosphere. Easy right? All you would have to do is to convince the entire world to stop driving cars, flying planes, heating there houses will fossil fuels and generating electricity in ways the generate greenhouse gases.

    We currently DO NOT have the technology to continue to use fossil fuels without poisoning out planet. Even electric cars require a source of power to recharge them. It is questionable if you gain anything by not burning gas but rather charging your car via a coal burning plant.

    Then there is the added difficulty of corporate greed. There is perhaps 100 trillion dollars worth of oil remaining on our planet. Do you believe that Exxon is going to go along with losing its market?? Hell no! They want to sell every drop of oil and transition us into a new source of power that will be as lucrative as possible for them. In short if we leave our future energy needs to the corporations that are raping us today, they'll position themselves to continue to bleed us tomorrow.

    I am likely to be skeptical anytime someone...

    (1)...tells me that I should believe something because other people believe it
    (2)...isn't capable of discussing alternate theories
    (3)...is intolerant of other theories
    (4)...insults me for not accepting their theory

    Basically, the more it looks like a religious issue, the more likely I am to be
    skeptical of it.

    I do believe it's important to reduce our emissions and our consumption of "dirty" energy,
    and so one the one hand, I'm sympathetic to global warming since it would encourage people
    and governments to do things that I think they should be doing anyways. On the other hand,
    however, most proponents of the human-caused-global-warming theory fail at least 3 of the
    4 criterion above.

    If you want to convince me of something, the first thing that you need to do is demonstrate
    that you're capable of thinking critically about it. Only then can we actually discuss the
