Indeed, tragically and paradoxically, among Republicans acceptance of the science decreases with their level of education as well as with their self-reported knowledge: Whereas Democrats who believe they understand global warming better also are more likely to believe that it poses a threat in their lifetimes, among Republicans increased belief in understanding global warming is associated with decreased perception of its severity.
