Overall, Americans' beliefs and attitudes about global warming have remained relatively stable over the past several months, with a few exceptions. There has been a slight increase in the proportion of people that believe global warming is happening and a slight decrease in the proportion that believe it is caused by mostly by human activities. There has also been a slight decrease in the proportion of people who believe that most scientists think global warming is happening; this decline is at odds with the widespread agreement among scientists that global warming is happening and primarily human caused. The public also overestimates the level of global warming disbelief in the United States. Finally, in this election year, we find that approximately half of Americans (47%) trust President Obama as a source of information about global warming, which is essentially unchanged since November of 2011. By contrast, only 21 percent of Americans trust Mitt Romney on this issue and his level of trust dropped 5 points since November, with “strong distrust” increasing by 8 points to 39 percent.
