Here is an awesome summary of responses to the global warming deniers.
It floors me how so many people can be misled so easily into thinking that global warming is anything but established reality. I am sure that those who are responsible for the campaign against climate change science are well aware that global warming is real, but have a financial stake in fighting policies designed to reduce carbon output. What is most discouraging to me is that so many in this country have never been taught or encouraged to think critically, do not understand how to distinguish scientific evidence from myth, and are oblivious to the sources of the information that they accept as "fact".
This is the same situation that creates the all too familiar demands that creationism (or its proxy, "intelligent design") be taught alongside the "theory" of evolution in high school biology classrooms.
