Here is the latest report (October 2017) from Yale Program on Climate Change Communication. The nationally representative survey finds that:
- The number of Americans “very worried” about global warming has reached a record high (22%) since first measured in 2008. A majority of Americans (63%) say they are “very” or “somewhat” worried about the issue.
- Nearly four in ten Americans (38%) say they discuss global warming with family and friends “often” or “occasionally,” an increase of 12 percentage points since March 2015. However, more say they “rarely” or “never” discuss it (62%). Additionally, half of Americans (51%) say they hear about global warming in the media at least once a month, and one in four (25%) say they hear people they know talk about global warming at least once a month.
