In a recent survey of 1,000 U.S. likely voters, 31 percent said global warming could be the most fearsome weapon of mass destruction.

 

Here’s what else the poll showed:

 

While 31 percent agree with Secretary of State John Kerry’s assessment that global warming is now “perhaps the world’s most fearsome weapon of mass destruction,” 54 percent disagree and 15 percent are undecided.

 

47 percent think global warming is a proven scientific fact, but 45 percent say there is still credible disagreement within the scientific community.

 

36 percent agree with the urgency Kerry expressed in his speech in Indonesia and say the world is headed toward an irreversible catastrophe if we fail to deal with global warming in the near future, but 42 percent disagree with this apocalyptic forecast and 22 percent are not sure.

 

51 percent of Democrats think global warming is “perhaps the world’s most fearsome weapon of mass destruction”; 80 percent of Republicans and 61 percent of voters not affiliated with either major party disagree.

 

70 percent of Democratic voters believe global warming is proven scientific fact, but 74 percent of Republicans think there is still credible disagreement within the scientific community, and among unaffiliated voters, 46 percent say fact, 49 percent disagree.
