Climate change opinion by country

For more about opinion in general, see Public opinion on climate change.

Proportion who report knowing "something" or a "great deal" about global warming. Darker areas indicate a greater proportion of individuals aware, yellow indicates no data.

Proportion responding yes when asked, "Temperature rise is part of global warming or climate change. Do you think rising temperatures are [...] a result of human activities?"

Proportion responding that global warming is a serious personal threat.

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. The Gallup Organization 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.

Weighting countries to a 2008 World Bank population estimate, sixty-one percent of individuals world-wide are aware of global warming, developed countries more aware than developing, with Africa the least aware. Latin America and developed countries in Asia lead the belief that climate change is a result of human activities while Africa, parts of Asia and the Middle East, and a few countries from the Former Soviet Union lead in the opposite. Awareness often translates to concern, although of those aware, individuals Europe and develop countries in Asia perceive global warming as a greater threat than others.

Caused by human activity 

Responding yes when asked, "Temperature rise is part of global warming or climate change. Do you think rising temperatures are [...] a result of human activities?"
