The Christian Post, Thursday, March 11
48 percent of the public think that global warming is generally exaggerated, up from 41 percent in 2009 and 31 percent in 1997, when Gallup first asked the question. Gallup noted that the percentage of Americans who believe global warming is generally overblown is the highest on its record.
“The last two years have marked a general reversal in the trend of Americans’ attitudes about global warming,” reported Gallup. “[T]he public opinion tide turned in 2009, when several Gallup measures showed a slight retreat in public concern about global warming. This year, the downturn is even more pronounced.”
There was also a change in opinion on what causes global warming. Exactly half of the public believes that human activities are mainly responsible for the increase in the Earth’s temperature over the last century. This is a significant drop from the 61 percent in 2007 that held this view and the 58 percent in 2008.
The percentage of Americans who believe the warming of the Earth is mostly due to natural changes in the environment has steadily increased in recent years. In 2010, 46 percent hold this view, up from 38 percent in 2008 and 35 percent in 2007.
