Fewer than half of Americans polled by the Pew Research Center believe humans are causing global warming, and a declining number even believe the Earth is experiencing a warming trend.
The survey, conducted by the Pew Research Center for the People and the Press, finds "roughly half, or 47 percent, of Americans say the Earth is warming because of human activity, such as the burning of fossil fuels."
Nearly as many, 45 percent of respondents, contend the higher Earth temperatures are due to "natural environment patterns," that no global warming exists, or that causes cannot be scientifically determined.
And it's people like this that are setting the record straight:
