This study identified factors that affect climate change risk perception in a community college class. The purpose of this research was to determine if students were more influenced by cultural cognition (political affiliation) or science comprehension. Students in an undergraduate level environmental science and biology class were evaluated, using an online survey, for science comprehension level, political affiliation and risk perception at the beginning and end of each course. Data were analyzed to determine improved scientific literacy and any variation in risk perception. The research found that science comprehension did not contribute significantly to increased risk perception and that political affiliation or political views had a more significant effect on risk perception.
