One-in-five respondents in Canada (20%) and the United States (21%) believe that global warming is a fact, and is mostly caused by natural changes—a view shared by 27 per cent of Britons. Finally, whereas 21 per cent of both Americans and Britons think that global warming is a theory that has not yet been proven, only 14 per cent of Canadians agree with this notion.
In Canada, respondents in the Atlantic Provinces (75%) and Quebec (71%) are more likely to say that global warming is a fact and is caused by emissions, along with Americans in the West (48%), and Britons in London (48%) and Scotland (47%).

Analysis
The proportion of Canadians who think global warming is a theory that has not yet been proven has not reached 20 per cent in any survey conducted by Angus Reid Public Opinion since 2009. In the United States and Britain, climate change skepticism has either reached or surpassed the 20 per cent mark in 10 of the past 12 measurements.
Domestic economic conditions continue to play a role in perceptions about environmental protection. In Canada, the group that calls for the protection of the environment outranks the group that seeks to foster economic growth by 38 points. The difference is much smaller in the United States (18 points) and Britain (13 points).
