Ok, without resorting to insults or childishness, here's what I've noticed in regards to global warming, and really science in general with regards to political leanings.
There is a faction on each side that is anti-science. On the right that anti-science occurs as a result of 2 things, either science is in opposition to religion or is in opposition to big business. On the left that anti-science occurs when they believe science is in opposition to what is natural.
For the right this means that those who are anti-science believe in things like birth begins at conception or gay conversion therapy for the religious. And they are against things like global warming for the ones who are pro big business.
For the left this means you have those who are anti-vaccine and those who are anti-GMO foods for those who believe those things are "unnatural".
Neither the left nor the right has a monopoly on dumb anti-science beliefs.
It's just on the right you have more elected officials who talk up a couple of those anti science beliefs and on the left it's usually unelected dumb celebrities.
Edit: I will also mention an opposition to nuclear energy on the left despite it being a cleaner alternative to fossil fuels as an issue that is anti science. (yes there are real concerns, but it's still better than burning coal)
