Another poll casts doubt on global warming

Reporter Jennifer Robison of the Las Vegas Review-Journal has found that the political environment is getting less friendly for proposed policies aimed at curbing so-called global warming.

As evidence, she points to a series of Gallup surveys.

Here's what Gallup found: The number of Americans who say the media have exaggerated global warming jumped to a record 41 percent in 2009, up from 35 percent a year ago. The most marked increase came among political independents, whose ranks of doubters swelled from 33 percent to 44 percent. Republican doubters grew from 59 percent to 66 percent, while Democratic skeptics stayed at around 20 percent.

What's more, fewer Americans believe the effects of global warming have started to occur: 53 percent see signs of a hotter planet, down from 61 percent in 2008. Global warming placed last among eight environmental concerns Gallup asked respondents to rank, with water pollution landing the top spot.

Another recent Gallup study found that, for the first time in 25 years of polling, more Americans care about economic growth than the environment. Just 42 percent of people surveyed said the environment takes precedence over growth, while 51 percent asserted expansion carries more weight. That reverses results from 2008, when 49 percent of respondents said the environment was paramount and 42 percent said economic growth came first. In 1985, the poll's first year, 61 percent placed a bigger priority on the environment, while 28 percent ranked economic growth highest.
