Pew Research reports:
Concern about global climate change is particularly prevalent in Latin America, Europe, sub-Saharan Africa, and the Asian/Pacific region, but majorities in Lebanon, Tunisia and Canada also say climate change is a major threat to their countries. In contrast, Americans are relatively unconcerned about global climate change. Four-in-ten say this poses a major threat to their nation, making Americans among the least concerned about this issue of the 39 publics surveyed, along with people in China, Czech Republic, Jordan, Israel, Egypt and Pakistan.
