At 41 percent, the proportion of Americans who think global warming is exaggerated has been on a steady climb since 2006, when only 30 percent of Americans surveyed by Gallup said that.
Gallup attributes the rise to Republicans and independents believing media coverage of global warming is exaggerated. In the past 12 months alone, the ranks of Republican doubters grew from 59 percent to 66 percent, and independents from 33 percent to 44 percent. Among Democrates, the rate remains about 20 percent.
The EPA recently reported that greenhouse gas emissions grew 1.4% in 2007. Scientists say climate change is approaching a "critical threshold."
Further research says that climate damage is unstoppable.
