Gallup finds the American public shows an all-time high level of concern for global warming

The American public concern for global warming has arrived at an all-time high, as a new Gallup survey reveals. As many as 45 percent Americans worry a great deal about global warming, up by 8 percent compared to last year. The American public not only displays an unusually high level of concern for this issue but also exhibits more confidence to believe in the scientific consensus on, human cause of, and dire consequence of global warming.
