When I decided to use the above title, I was pretty sure a majority of the U.S. public would select the first option (human-caused). But after selecting it, did a search for a recent poll from a respected pollster that asked this question.
I found a Pew Research poll that asked, “How much do Americans think humans contribute to climate change?” The answers to this question were:
- A great deal      45%
- Some   29%
- Not too much or not at all          25%
So, 74% believe that humans contribute to climate change a great deal or some.
