High Quality Content by WIKIPEDIA articles! Climate change opinion is the aggregate of public opinion held by the adult population. Cost constraints often restrict surveys to sample only one or two countries from each continent or focus on only one region. Because of differences among questions, wording, and methods-it is difficult to reliably compare results or to generalize them to opinions held world-wide. In 2007-2008, the Gallup Poll surveyed individuals from 128 countries in the first comprehensive study of global opinions. Gallup aggregated opinion from the adult population fifteen years of age and older, either through the telephone or personal interviews, and in both rural and urban areas except in areas where the safety of interviewer was threatened and in scarcely populated islands. Personal interviews were stratified by population size or geography and cluster sampling was achieved through one or more stages. Although error bounds vary, they are all below ±6% with 95%confidence.
