As highly religious people in the US become more science literate, they increasingly deny climate change.
...among highly religious individuals, as their ability to comprehend science increases, so does their denial of the risk posed by global warming...
The researcher went on to say that he isn't sure why greater religiosity predicts greater denial of climate change. But in his data—with a representative sample of over 2,000 Americans—it clearly does.
There are two major possibilities. And there is probably some truth to both of them.
There is the "the enemy of my enemy is my friend" theory. In other words, anti-evolutionists and climate deniers were both getting dumped on so much by the scientific community that they sort of naturally joined forces.
But there's also the "declining trust in science" theory, according to which political conservatives have, in general, become distrustful of the scientific community (we have data showing this is the case), and this has infected how they think about several different politicized scientific issues.
