ABSTRACT
According to surveys conducted since 2008, large majorities of Americans have believed that the earth’s temperature has been gradually increasing over the last 100 years, have believed that such warming is at least partly human-caused, have believed it is a threat, and supported government action to reduce future emissions of greenhouse gasses (what might be called a set of “green” opinions; see the first four rows of Table 10.1). Such majorities have also appeared among Independents (see rows 7 and 11 of Table 10.1) and might seem to suggest that political candidates could gain votes by staking out green positions on global warming and that taking not-green positions could cause candidates to lose votes.
