A new Washington Post-ABC News poll found that four out of five Americans believe global warming is happening. That's 8 percent fewer than the previous year. The poll's findings also show that 55% of respondents think the United States should curb its carbon output even if major developing nations such as China and India do less. And the poll shows that a majority of respondents still support legislation to cap emissions and trade pollution allowances, by 53% to 42%.
Amanda Feinberg, a retired administrative assistant living in South Williamsport, Penn. says she became disenchanted with the idea of human-caused global warming when former vice president Al Gore launched a public awareness campaign with his documentary, "An Inconvenient Truth."
