Pew Research poll: ‘Dealing with global warming’ ended up in second last place in 2007. Between 2008 and 2013, it ranked last (select a year and then ‘Overall’ here). Here’s what happened after that:
2014: second last
2015 second last
2016 third last (the first year Pew began calling it ‘global climate change’)
2017: second last (see bottom of the page)
2018: second last
2019 second last
Moral of the story: There has never been any evidence that climate change is a top concern for most Americans. This is not a crowd-pleaser or a vote-getter.
