Thank you for posting the link. The poll actually measures belief in the consensus among climate scientists. That's different. From the first paragraph:

"Nearly three-quarters of Americans don’t trust that there is a large “scientific consensus” amongst climate scientists on human behavior being the cause of climate change ..."

That's unfortunate. The actual consensus approaches 100% —

A scientific paper analyzed the 2% of scientific papers that reject AGW and found the rejections to be the result of errors in methodology. From the paper's abstract:

"An analytical tool has been developed to replicate and test the results and methods used in these studies; our replication reveals a number of methodological flaws, and a pattern of common mistakes emerges that is not visible when looking at single isolated cases. Thus, real-life scientific disputes in some cases can be resolved, and we can learn from mistakes."
