With climate change town hall, CNN has an opportunity to show what it’s learned

“AMERICANS’ BELIEF IN GLOBAL WARMING sinks as Republicans shift,” a headline on CNN reads. The piece, from 2009, reports on a poll showing that roughly a third of those who accept that global warming is real “think it is due to natural causes, rather than manmade causes such as industrial emissions.” As a reaction to a Democratic White House, the article suggests, the number of people in America who believe that global warming has been caused by humans fell—from 54 percent in the summer to 45 percent in December. And, the article continues, “the number who say the United States should reduce emissions even if other countries do not follow suit has also dropped.”
