Final answer:
Many Americans do not believe that there is a scientific consensus on human-caused climate change, which affects their opinions on the issue and the policies they support.
Step-by-step explanation:
According to a poll conducted by Stanford University, a widespread among Americans belief is that many do not accept the consensus view of climate science regarding climate change. Specifically, when asked whether most scientists believe that the Earth is warming due to human activity, 55% of Americans say 'No' or that they don't know. This indicates a significant number of Americans are unaware that there is a general scientific agreement on anthropogenic climate change. This level of skepticism has implications for individual opinions on climate change and the government policies they are willing to support to address it.
