From the 2013 Yale report Climate Change in the American Mind. “Only one in four know that there is a scientific consensus on climate change—only 25 percent of Americans understand that there is no argument about whether or not global warming is occurring among climate scientists. Between 97 and 98 percent of actively publishing climate scientists believe Earth is warming.
Fewer than half of Americans (38%) believe they personally will be harmed a “moderate amount” or a “great deal” by global warming. By contrast, half or more believe that global warming will harm future generations of people (65%), plant and animal species (65%), people in developing countries (56%), people in other industrialized societies (54%), or people in the U.S. (53%).
Four in ten say people around the world are being harmed right now by climate change (39%) and one in three (34%) say global warming is currently harming people in the United States.
The majority of the Dismissive (55%) believe there is a lot of disagreement among scientists about whether or not global warming is happening. Similarly, about four in ten of the Doubtful (43%) and Cautious (43%) believe there is a lot of disagreement.”
