69% Say It The debate over global warming has intensified in recent weeks after a new NASA study was interpreted by skeptics to reveal that global warming is not man-made. While a majority of Americans nationwide continue to acknowledge significant disagreement about global warming in the scientific community, most go even further to say some scientists falsify data to support their own beliefs. The latest Rasmussen Reports national telephone survey of American Adults shows that 69% say its at least somewhat likely that some scientists have falsified research data in order to support their own theories and beliefs, including 40% who say this is Very Likely. Twenty-two percent (22%) dont think its likely some scientists have falsified global warming data, including just six percent (6%) say its Not At All Likely. Another 10% are undecided. (To see survey question wording, click here .) The number of adults who say its likely scientists have falsified data is up 10 points from December 2009 . Fifty-seven percent (57%) believe there is significant disagreement within the scientific community on global warming, up five points from late 2009. One in four (25%) believes scientists agree on global warming. Another 18% arent sure.
