1: Climate change is occurring (74%)
2: Humans are causing the warming (75%)
3: The US Government should regulate greenhouse gas emissions (76%)
"... huge majorities of Americans still believe the earth has been gradually warming as the result of human activity and want the government to institute regulations to stop it.
In our survey, which was financed by a grant to Stanford from the National Science Foundation, 1,000 randomly selected American adults were interviewed by phone between June 1 and Monday. When respondents were asked if they thought that the earth's temperature probably had been heating up over the last 100 years, 74 percent answered affirmatively. And 75 percent of respondents said that human behavior was substantially responsible for any warming that has occurred.
For many issues, any such consensus about the existence of a problem quickly falls apart when the conversation turns to carrying out specific solutions that will be costly. But not so here.
Fully 86 percent of our respondents said they wanted the federal government to limit the amount of air pollution that businesses emit, and 76 percent favored government limiting business's emissions of greenhouse gases in particular. Not a majority of 55 or 60 percent — but 76 percent."
