10/27/2010 - Views about the existence and causes of global warming have changed little over the past year. A new Pew Research Center poll finds that 59% of adults say there is solid evidence that the earth’s average temperature has been getting warmer over the past few decades. In October 2009, 57% said this.
Roughly a third (34%) say that global warming is occurring mostly because of human activity, such as the burning of fossil fuels, which also is little changed from last year (36%).
The latest national survey by the Pew Research Center for the People & the Press, conducted Oct. 13-18 among 2,251 adults reached on landlines and cell phones, finds that 32% say global warming is a very serious problem while 31% think it is somewhat serious. A year ago, 35% described global warming as a very serious problem and 30% said it was somewhat serious.
