Americans are increasingly alarmed about global warming

A survey of U.S. adults from 2013 to 2018 shows a significant shift in climate change attitudes, with the proportion of 'Alarmed' individuals doubling to 29% by December 2018, while 'Dismissive' and 'Doubtful' segments decreased.

• Between 2013 and 2018, the proportion of Americans categorized as "Alarmed"—those most worried about global warming and supportive of aggressive carbon pollution reduction—more than doubled, reaching an all-time high of 29% in December 2018.
• There has been a decline in climate skepticism over the five-year period; the "Dismissive" and "Doubtful" segments each fell to 9% by the end of 2018, representing a combined 12-point decrease since 2013.
• The overall trend in the U.S. population shows a movement away from skepticism toward concern, with the "Alarmed" now outnumbering the "Dismissive" more than 3 to 1 (29% vs. 9%), compared to 2013 when both groups were equal at 14%.
