American scientists and the general public hold vastly different views on key scientific issues including the role of people in causing climate change, the safety of genetically modified food, and evolution, a poll released on Thursday showed.
Eighty-seven percent of scientists questioned by the Pew Research Center said human activity was the main cause of global climate change, compared with 50 percent of the public.
Twenty-five percent of the public said there was no solid evidence the climate was warming, up from 11 percent in a similar 2009 survey.
