A global survey reveals significant concern about climate change, particularly in Latin America and Sub-Saharan Africa, with Brazil showing the highest concern and China the least. While the majority of respondents support limiting greenhouse gas emissions, partisan divisions affect perceptions, especially in the U.S., where younger individuals demonstrate greater concern and willingness to act. Overall, many believe major lifestyle changes are necessary to address the issue, with strong support for affluent countries to take more action than developing nations.
