A new poll of 15 nations, most of them in the developing world, finds that majorities of the people canvassed want their governments to take steps to fight climate change, even if that entails costs. People signaled they would support public measures to limit greenhouse gas emissions and step up adaptation measures. For example, respondents would support higher fuel efficiency standards for cars, preserving or expanding forests, and extending funding to vulnerable countries so they can develop hardier crops suited to more severe climates.
