Too Hot for an A

Most Americans Lack Basic Knowledge of Climate Issues, Study Finds | Reuters: "According to the survey, 57 percent of respondents know that the greenhouse effect refers to heat-trapping gases in the atmosphere; 45 percent understand that carbon dioxide traps heat from the planet's surface; and only 25 percent are aware of coral bleaching or ocean acidification. And the majority of respondents had significant misconceptions about climate science, including the incorrect belief that the hole in the ozone layer, toxic waste, aerosol spray, and acid rain cause global warming. Based on these results, the authors say only 8 percent of respondents would have knowledge equivalent to a grade of an A or B, and more than 52 percent would receive an F grade."
