According to a Gallup survey conducted in 2010 and released April 22, 2011, residents of the world are more likely to attribute global warming to human activity, rather than nature. When asked specifically about rising temperatures, 35% of adults in 111 countries said warmer temperatures were a result of human activity, while 14% blame nature. Those who faulted both represented 13% of those surveyed. In the United States, where 4% of those surveyed were unaware of global warming, 34% blame human activity, 47% blame nature, and 14% blame both. According to this poll, the percentage of Americans who blame nature is the highest in the world.
Bottom line: Most residents of the world blame human activity for global warming, based on a Gallup poll conducted in 2010 and released April 22, 2011. In the U.S., 47% blame nature — the highest percentage from all countries surveyed in the world
