The climate science debate has two important components to it. This issue focuses on one component, and that is the anti-science attack on climate science. This has the same source of ignorance and zealotry that has challenged teaching evolution in the classroom. This is a stand of religious based ignorance against science. I have not met anyone who understands the scientific process who challenges the theory of evolution. I am using the scientific definition of theory, which is an operating model, and not the "theory is not a fact" arguement that my religious friends pick up.
The second component to climate science is that there are some great issues of modern science and society that can be taught here. To not teach this in the classroom is missing out on a real opportunity to teach critical thinking that children can get passionate about.
You can teach about data collection, and how this can be a source for controversy.
You can teach about computer modeling and statistical analysis. What these tools are great for, and where they fall short.
Plenty to teach about weather vs. climate, and what the climate means for other systems on the planet.
Lab experiements on basic components of the atmosphere, and why they don't always translate to the actual model of the world.
You can teach the ethics of how to prioritze science against society and economic concerns.
Lots more stuff that I am not getting in to.
My point being, this is another area where zealotry is screwing up a great opportunity to train the next generation of scientists.
