Polls have consistently shown that Americans’ understanding of global warming grows with an increase in extreme weather events. In the aftermath of Superstorm Sandy, that number continues to grow.
According to a new Rasmussen poll conducted a day before the election and released this morning, 68 percent of American voters said that global warming is either a “very serious” or “somewhat serious” problem. This represents a major increase over the last few years. In 2009, Rasmussen reported that only 46 percent of Americans believed that global warming is a problem.
The Rasmussen poll backs up others showing an increase in awareness of the problem. An October poll from George Mason University and the Yale Project on Climate Change Communication showed that 74 percent of Americans understand that “global warming is affecting weather in the United States” — an increase of 5 points from a March 2012 survey. The Yale/George Mason poll also found that a majority of respondents said global warming made the summer heat wave and Midwest drought worse.
In February, a poll released by the Brookings Institute showed a 7 percent increase in the number of Americans who say that the planet is warming — with that increase influenced by extreme weather events.
