Below the fold I detail what the available poll data suggests about how framing shaped public preferences on Kyoto. The passage is taken from a journal article I have forthcoming (e-mail me for a copy).
Besides domestic policy measures to counter global warming, the public has been asked across surveys their views on the longstanding efforts to negotiate international agreements on greenhouse gas emissions. As early as 1990, eight out of ten Americans believed that the U.S. should take the lead internationally in preventing the greenhouse effect. However, more than ten years later, when asked specifically to evaluate George W. Bush's decision to forego participation in the Kyoto climate treaty, given earlier findings relative to low levels of attention and knowledge about the agreement, it is not surprising that several surveys show that many citizens did not hold an opinion on the matter. Other surveys provide evidence that the strategic framing of the Kyoto treaty and its possible impacts can shape public preferences.
For example, in surveys conducted by the Chicago Council on Foreign Relations (CCFR), PIPA, and Gallup between 2002 and 2005, the tentative nature of public opinion on Kyoto is revealed when considering response category effects. In each of the surveys, respondents were asked if they believed the U.S. should participate in the Kyoto agreement on global warming. In the CCFR survey from 2002, and the PIPA surveys from 2004 and 2005, 64%, 65%, and 73% support participation (Table 28). Yet consider two Gallup surveys that differ slightly in question wording, in both polls only 42% of Americans answer that the US should abide by the treaty, while 36% and 35% in the two surveys volunteered that they were "unsure" or had "no opinion" (Table 29).
Question wording effects are apparent across other surveys. In two Gallup questions from April and June 2001, Bush's interpretation that the Kyoto treaty would hurt the economy while demanding too little of developing countries was presented with no counter argument. In these polls, 41% and 40% said they approved of Bush's decision to withdraw, while 48% disapproved. In contrast, when Pew asked about the decision in April and August 2001; and when Gallup queried respondents in a separate survey conducted in July 2001, no reason for the decision to withdraw from Kyoto was given. In these cases, absent a specified justification, approval of Bush's decision rested at only 25%, 29%, and 32% respectively, with disapproval at 47%, 44%, and 51%. Gallup asked about the decision to withdraw from Kyoto again in 2005, yet this time they labeled the event a "United States' decision" rather than a Bush decision, and offered "unsure" as a response category. In reply to this alternative question wording, 59% answered "unsure" with only 20% approval and 21% disapproval (Table 30).
