There has been a moderate uptick over the past two years in the percentage of Americans that believe in climate change, although substantially fewer Americans say there is solid evidence of global warming than did so from 2006 to 2008, according to a report by the Pew Research Center for the People and Press.
Currently, 63 percent say there is solid evidence that that the earth’s average temperature has been getting warmer over the past few decades. In October 2009, 57 percent expressed this view. During 2006 to 2008, more than seven-in-ten Americans believed there was solid evidence of global warming, the report says.
Since 2009 there have been sharp increases in the number of independent voters and, interestingly, moderate and liberal Republicans that believe in climate change.
At present 63 percent of independents say there is solid evidence of rising temperatures up from 53 percent in October 2009. Some 63 percent of moderate and liberal Republicans now see evidence of global warming, compared to 41 percent in the Pew poll two years ago.
The Pew poll echoes the findings of a Reuters/Ipsos poll released in September. The Reuters poll found that 83 percent of Americans believe the Earth has been warming, up from 75 percent last year.
Reuters attributed the rise to a reaction to climate skepticism by the Republican presidential candidates.
