あいかわらず支持政党により乖離する気候変動についての世論

PEW Researchによる気候変動についての世論調査結果が発表された。
Two-thirds of Americans (67%) say there is solid evidence that the earth has been getting warmer over the last few decades, a figure that has changed little in the past few years. While partisan differences over climate change remain substantial, Republicans face greater internal divisions over this issue than do Democrats.

やはり面白いのは支持政党別の数字。

気候変動の証拠はかたいかという質問でも大きく差が開いている。

特に、人類要因か否かの質問の開きは大きい。

なお、調査は以下もように、全米18歳以上の1504名に対して、2013年10月9-13日に、752名はついて固定電話、752名について携帯電話で行われた。
The analysis in this report is based on telephone interviews conducted October 9-13, 2013 among a national sample of 1,504 adults, 18 years of age or older, living in all 50 U.S. states and the District of Columbia (752 respondents were interviewed on a landline telephone, and 752 were interviewed on a cell phone, including 407 who had no landline telephone). The survey was conducted by Abt SRBI. A combination of landline and cell phone random digit dial samples were used; both samples were provided by Survey Sampling International. Interviews were conducted in English and Spanish. Respondents in the landline sample were selected by randomly asking for the youngest adult male or female who is now at home. Interviews in the cell sample were conducted with the person who answered the phone, if that person was an adult 18 years of age or older.

PEWの調査は2006年からと短期なので、政党支持による世論の乖離が進む過程は見えない。そのあたりは、Gallup Pollのデータを見るとわかりよい
