Global warming or more accurately, global climate change is not a scare but a reality.
It is the cause of the climate change that has been politicized.
And also what best to do about it....
My opinion of the science is that there is strong confirming evidence that global warming is under way (for whatever reason). However non-attempts to deal with it like Kyoto, which seems solely to be a kind of developed world self-flagellation with no discernable benefit to anyone have rightly been rejected by the administration.
MOre than the cause, the suggested actions are politicized. The Kyoto treaty did nothing to alleviate any greenhouse effect. However, abandoning science doesn't give one arguments so show that.
