"Reuters/Ipsos: More Americans Believe World Is Warming"
"More Americans than last year believe the world is warming and the change is likely influenced by the Republican presidential debates, a Reuters/Ipsos poll said on Thursday.
The percentage of Americans who believe the Earth has been warming rose to 83 percent from 75 percent last year in the poll conducted Sept 8-12.
U.S. Republican presidential candidates, aside from Jon Huntsman, have mostly blasted the idea that emissions from burning fossil fuels and other human actions are warming the planet.
