== Pew polls on this question every year == 

 For some reason, I have a better opinion of Pew's global research. It seems that every year they ask the same question of quite a lot of countries: "On another topic, in your view, is global warming a very serious problem, somewhat serious, not too serious, or not a problem?"  (http://pewresearch.org/pubs/1427/global-warming-major-problem-around-world-americans-less-concerned) 
 If I had time, I'd rewrite this article substantially.
