(Oct. 29, 2010) Public opinion on global warming is cooling.

Fewer and fewer Americans accept the theory that humans are responsible for global warming, according to the latest Pew Poll. The number of believers across the U.S. population as a whole now stands at 34%.

Fewer than one in three Independents and one in six Republicans hew to the global warming line. A majority of Democrats, 53%, do accept the view that humans are responsible for global warming.

Many Democrats, however, are coming to realize that the science is not settled on global warming – just 59% now say that scientists agree that the earth is getting warming due to human activity.
