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."

      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?

    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.
