According to Klein, what did the Yale Cultural Cognition Project reveal about political leanings in the nonfiction book, This Changes Everything?

According to Klein, the Yale Cultural Cognition Project found that one’s political leanings had a large impact on whether he believed in climate change or not. An individual’s political leanings are a bigger indicator of their belief in climate change than age, ethnicity or education level. A much larger percentage of climate change deniers are conservative Republicans. Deniers do not like to believe that their actions may be harming the environment which gives them more fodder for not believing that climate change exists.
