"If you look across the survey, one big challenge for anyone who's proposing geoengineering methods is how to even begin to explain this to the general public, and then begin to make this credible," said Barry Rabe, a professor at the University of Michigan's Gerald Ford School of Public Policy.
Rabe, who conducted the survey with Christopher Borick, director of the Muhlenberg College Institute of Public Opinion, said public opinion research on geoengineering is limited.
That makes it hard to compare concerns about geoengineering to attitudes about other controversial technologies, like nanotechnology or genetically modified organisms.
But what is interesting about the new results, Rabe said, is that few respondents indicated they were neutral about geoengineering.
"One thing that surprised us a bit is the percentage of people who responded with an opinion," he said. "In every case, we gave them the option to say 'not sure.' I frankly expected more people to punt on this one."
