California Lawmaker Seeks Climate Change as part of Public Education
Andrew Feinberg writes "A California State Senator is seeking to mandate climate change as part of the standard science curriculum. Other members of the legislative body seek to teach an opposing view. 'Simitian noted that his bill wouldn't dictate what to teach or in what grades, but rather would require the state Board of Education and state Department of Education to decide both. Although global warming is mentioned in high school classes about weather, it is currently not required to be covered in all textbooks, said the head of the California Science Teachers Association ... teachers would have plenty to discuss: rising levels of carbon dioxide, how temperatures are measured globally, and what is known and not known about global warming.'"
Well, climate change is an important contemporary issue in science, no matter what your opinion. I think injecting a bit more science into the whole thing would only be a good idea. Then again, judging from some of the comments regarding climate change, it seems to me that science education in general needs to be addressed.
/. written though it were gospel:
The thing that amazes me about this whole thing is that (otherwise intelligent) people seem to have been suckered by marketing. For example, companies that advertise about C02 being a harmless gas are simultaneously investing in arctic oil exploration (on the assumption that the arctic ice is melting). Maybe the biggest thing that needs to be taught in science is objective reasoning - something that seems fairly thin on the ground..
Here's something I often read on
"correlation != causation" - true, but I'd challenge anyone to name a single scientific "law" we _know_ to be caused, and don't "merely" observe correlation.
The other thing that amazes me are the number of people who believe really weird things about climate change research. For example, I've read comments alleging that climate scientists "tweak" their models to fit known weather patterns, but never verify those models on other data. This is such a patently ridiculous allegation that in any other field it would be laughed off the stage, but for some reason there is a group of people who are desperate to dis-believe in climate change no matter what the evidence.
I think this is a critical issue, but I'd rather not turn it into a situation where people are fighting over whether they get to teach the answer. Rather, I'd make it a mandate to produce students who are capable of intelligently discussing the questions.
Here's what I'd teach them:
Enough chemistry to understand what a compound is, and how atoms rearrange in order to make different molecules, and how energy is required and released in the process. One could teach this from a fairly young age, even without a full chemistry course. Just so they're conversant in the concepts and can know they want to learn more.
Enough math to know what exponents are and what the difference is between a straight line and non-linear curve is. Even if they blur the huge difference between squares and exponentials, the notion that one can't simply rely on knowing that if it took x years to do something, it will take x more years to do twice that, it would be good.
Also, again in the math front, enough math to understand simple optimization issues--nothing fancy. The ability to optimize the area of a rectangle is almost enough. They must be able to do simple things like know when it's good for a few people to do big things and when it's better for a lot of people to do little things and when neither of these will work and everyone has to do something big in order for anything to matter.
Enough math to be able to comprehend the sheer quantity of waste and pollution in the world.
Enough statistics and probabilities to be able to understand why something can happen one year, not happen another, and then happen again ... and yet still be a trend. That is, they must understand the
difference between a tendancy toward something and a promise that something
will occur.
Enough logic to understand what it takes to prove and disprove existential and universal quantifications.
Enough philosophy and morality to understand and discuss risk analysis and the general good.
Enough politics to understand how it's BOTH the case that an obviously good idea won't necessarily be adopted by the free market, and something that is forced by government won't necessarily fix a problem.
Enough economics to know how to calculate which investments are going to pay off and which are just boondoggles lining someone's pockets in the short term at the expense of the long-term good.
Enough history to revive the notion of sacrifice for the greater good and get people out of the "it's all about me" mode.
Enough biology to understand what an ecosystem is and how one thing affects another. There was a very good episode of the Wild Thornberrys where the ecosystem got upset by a small change and there was a big disaster. Required viewing of that would almost suffice in my eyes. Just enough to be able to understand the significance of the reefs going away or some plankton going away or polar bears going away in some sort of operational terms that didn't make it seems "distant and unrelated".
Enough common sense to understand that not all things labeled bio-degradable, green, or earth-friendly are actually saving people money. We don't have to teach which ones are, just that the question has to be asked and that the answers might be deliberately obscured.
And, just maybe, enough religion to understand that Noah didn't survive the Flood by sitting back and assuming it was God's will or that God would just take care of him.
And enough to know that the true meaning of Faith is that you have enough confidence in what you believe that you are not threatened by truth and science.
Bravo to the United Church of Christ for its recent "not mutually exclusive" stance on science and technology. (I'm not a member of that church, by the way. I just saw notice of this and thought it was cool.)

Firstly, the level of many of the posts here, the reflexive and snide referral to the principles of atmospheric science as religion indicate to me that an increasingly large group in society are hostile to science. Here is a New York Times article that argues just that, that there is a rising tide of anti-intellectualism building in America today.
As for the accusations of indoctrination, I believe that climate science should be taught in schools. However, it should be taught at a far more advanced level than they typical caricatures that appear in popular culture. Students should first be taught about the physics of electromagnetic radiation, about absorption, reflection, and emission. They should be given an understanding of how some wavelengths transparently pass through some materials, while others wavelengths are absorbed by the same materials. In my experience, students today typically have a terrible understanding of these concepts.
They should also be taught some basic atmospheric science. For example, they should know why the air becomes cooler as altitude increases (up to the thermosphere at least) because the reduced pressure causes the air molecules to move more slowly. This means that they should be familiar with gas laws, and with the concept of adiabiabatically raising a parcel of air. They should be taught about the latent heat in water vapor and also about relative humidity and the capacity of air to hold water vapor. They should understand that raising a parcel of air causes it to cool, thus reducing the amount of water vapor it can hold. When the water vapor condenses to form clouds, heat is released, causing the parcel of air to rise even faster...this is the main mechanism of storms.
Finally, they should be taught the mechanisms of the greenhouse effect. They should especially be taught that the typical pop culture caricature of the greenhouse effect is wrong. The greenhouse effect is typically portrayed as a sheet of gas reflecting infrared radiation back to Earth. This is not the way it works. Instead, increased carbon dioxide, especially at high altitudes (where it is dry) makes it more difficult for infrared radiation to escape to space. The high altitude carbon dioxide causes the Earth's infrared radiation to be emitted to space at a higher altitude. However, since the air is cooler at higher altitude, the infrared radiation is emitted to space less effectively, thus causing an increase in temperature of the entire system. Here is a nice summary.
If the material is taught in a logical scientific way, then I believe that it cannot be called indoctrination. If the students are familiar with the detailed science underlying the field of climate science, then they will be more able to judge between authentic and fallacious arguments. Mandating that this material be taught is really not that different than mandating that chemistry be taught.

Your argument is disingenuous. The importance of a greenhouse gas is more than simply the strength of its absorbtion lines, but also its sources/sinks and residence time in the atmosphere. Water is a strong absorber, but its distribution is highly time dependent and its residence time in the atmosphere is exceedingly short. Water acts as a strong feedback mechanism rather than a direct cause. The simple fact is that if there were no CO2 all of the water would freeze out of the atmosphere and its contribution to warming would be lost. See for example the Snowball Earth.
Water is highly unstable in Earth's atmosphere and has a very strong tendency at positive-feedback processes in both directions. If it gets colder and more ice starts forming, more water freezes to ice and makes it get even colder. Methane is a minor effect for a different reason. Without a constant source there would be no more methane in a very short time (it breaks down quite quickly in the atmosphere). CO2 however has a very long lifetime in the atmosphere and as such has a much stronger influence on long-term processes.
As much as I detest the idiots out there trying to hush-hush climate change significance, I also detest this idea that we must mandate "global warming" be taught in school. What about we just teach a well-rounded science curriculum? Why not mandate nano-science as part of the curriculum while we're at it?
The fundamental problem I have with this whole thing is that it would seem to be teaching an element of valid science for a political cause rather than for educational merit alone.
