Among those who see the irrefutable scientific evidence of global temperatures rising, only 42 percent believe that most of it should be attributed to human activity. In fact, when you break it down, 23 percent of Americans believe that natural patterns in the earth's environment are heating the earth, and another 27 percent don't believe there is any solid evidence of warming at all. The more appropriate question would be: Do you believe in man-made global warming? The answer: Less than half of Americans would say yes. That, even after the unrelenting cultural, educational and political bombardment we've all had to endure on the topic.
And though 33 percent of Americans believe that global warming is a "very serious" problem, that number has declined by 6 points since October 2012.
