The climate change consensus extends beyond climate scientists - IOPscience
The questions in the survey are the same as the ones given to climate scientists a few years ago, and are at the end of the paper. While 97% believe we are a significant contributor, but doesn't define what they mean as significant. A later question helps clear things up #27, has 70% believing we are responsible for more than 50% with 20% of respondents unsure.
Even as a skeptic I still fall into the 97%.
