26 Common Climate Myths Debunked
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."
Fact: Flamewars do, in fact, contribute to global warming. The increase in post count burdens servers and thus uses more electricity. Ad revenues increase allowing rich business men make more money to put gas in their hummers. Considering some 40% of the internet consists of flamewars of one type or another, the impact is rather significant.
Nobody was trying to support a population of six billion settled agriculturalists at the time, though.
Real Daleks don't climb stairs - they level the building.
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.
Those who can, do. Those who can't, sue.
How do you know previous climate fluctuations were without, as you put it, "zomg serious consequences" for the species living at the time?
Be wary of any facts that confirm your opinion.
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.
Anecdotal Evidence is just fantastic. Way to go. I think I will trust the peer reviewed journals for just a while longer though.

You didn't even mention the appreciable levels of hot air that emanate from those commenting.

If you read any articles about Global Warming you will see that some local areas will get colder, wetter, more snowfall, and more ice accumuluation because of shifting water currents and atmospheric wind patterns. The issue is GLOBAL WARMING, not is it warmer at my house.

As the publisher of J. Anec. Evid., I deplore the myth that anecdotal evidence is worse than your so-called "peer reviewed" evidence. We peer at each claim for quite a while, and only publish it if it meets our stringent two-pronged criteria:
1. It sounds good to us.
2. It makes some point that needs to be made.
Both Science and Nature have only ONE prong: repeatability. So citations from the Journal of Anecdotal Evidence are twice as sciency.
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. It's the same very effective tactic used by big tobacco for decades in the 60s to prevent recognition of the cancer causing properties of tobacco.
Lies about crimes
Well we'd ask them but they're all extinct. Oh... wait...
I'm trying to teach myself to set people on fire with my mind... Is it hot in here?
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.
I prefer Flambe as apposed flamebait.
Gentlemen! You can't fight in here, this is the war room!
Then we can decide for ourselves whether there's any link between smoking and cancer.
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 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.
Quite to the contrary of the GP's assertion, climate has caused catastrophically large extinction events in the past. Thankfully, climate doesn't swing wildly very often on it's own.
Also, notice that it's not, say, a high temperature or high CO2 levels that are bad. It's the *rapid change* that is bad, and as far as rate of change, this current one is only really bested by asteroid/comet impacts and supervolcanism. A disturbing example of this is the "Great Dying" (the Permian-Triassic event), largely brought about by Earth's largest known volcanic event (the eruption of the "Siberian Traps"), which doubled Earth's CO2 levels, created acid rain, and all sorts of other effects that mimic Man's impact on the modern world (the other major theory also involves global warming, but from methane unleashed by the traps instead of CO2; either way, the warming aspect is generally uncontested, as the evidence is so strong). Over a million or so years (most concentrated in a few hundred thousand), the vast majority of multicellular life died as ecosystems were thrown out of balance, and hundreds of millions of years of evolution were undone. For a while after this eruption, the dominant species on the planet were fungi -- decomposers. Slowly eating all of the dead.

Thank you xkcd.
Sounds like NS neglected to debunk the biggest myth of them all, namely that global warming means a uniform increase in temperature everywhere on the planet.
Sheesh, evil *and* a jerk. -- Jade
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.
So demonstrate the bias. Wild claims of "there could be bias" without actually pointing out the bias are worthless.
Why don't you think that human activity is a determining factor in the atmospheric CO2 levels?
Who are the scientists that say we need more study before taking action? How many of them are not getting paid by fossil fuel industries (e.g. coal, oil, and natural gas) or fossil fuel consuming industries (e.g. automobiles, electric power)?
Good one. It's funny to listen to a hundred scientists argue about this issue with so much more certainty and passion than scientists like me have. I'm not going to touch the issue, other than to lament the way that it has become politicized to the extent that random people buy ridiculous individual arguments and defend a position that has no scientific support.

What I really wanted to point out, though, was that "organic" products are actually a major problem to the "let's emit less CO2 and remove more" strategy. "Organic" crops take up more that twice as much land area per unit output, which has led to huge sections of rainforest cleared out to allow for more land-hungry organic food production. Organic food was never meant to be a pro-environmental movement. When the labeling was first conceived, the idea was to imply that the food was healthier because it contained bugs instead of poisons. The idea that pesticides would then be less prevalent in water supplies became tied to it, with good reason. But then from that pro-environmental argument, people got the idea that organic food must be good for the environment in every way. It's certainly not. Organic food is an important cause of deforestation in Central America, both directly (organic food grown there) and indirectly (increased organic production in the United States means lower overall agricultural output, which then increases the demand for agriculture in Central America). Organic food in some cases may be better for your health. In some ways, it's better for the environment. However, it's a big problem for the environment in other ways, so you'll have to make an educated choice.
Okay, one more thing. "Does 1 person make a real difference? Hell no" is one of the stupidest things I've ever seen posted on
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.
That moves you from merely correlation to causation. It's nice to see the goal posts moved yet again. Do they actually have to prove they are the sole cause, or can they demonstrate with 90-99% certainty that we are the primary cause?
