Below is an extract from Fox News:
"Rasmussen poll, conducted earlier this week, found 67 percent of Democrats believing that the U.S. has only 12 years to avert the “disastrous and irreparable damage to the country and the world” stemming from climate change. Out of all total likely voters, 48 percent of respondents believed the apocalyptic claim."
