In September, on a stage with a panel of fellow climate experts, NASA atmospheric scientist Kate Marvel said “We are more surethat greenhouse gas is causing climate change than we are that smoking causes cancer.”
But while 97% of climate scientists are convinced that human-caused global warming is happening, most Americans are unaware of this scientific consensus. Recent surveys of more than 8,000 U.S. adults find that even those who have great concern about climate change tend to underestimate the scientific consensus by a large margin.Our prior research has found that Americans can be categorized into six groups – dubbed Global Warming’s Six Americas. People categorized as “Dismissive” and “Doubtful” tend to disbelieve climate science, so it is unsurprising that they believe the scientific consensus to be lower (44% and 52%) than it actually is (97%).
However, even people with the greatest concern about climate change-the “Alarmed” and “Concerned”-also give estimates (84% and 73%) that fall well short of the actual level of scientific agreement.
