evidence: These are some of the principle findings from a new Pew Research Center survey. Most of the findings in this report are based on a nationally representative survey of 1,534 U.S. adults conducted May 10-June 6, 2016. The margin of sampling error for the full sample is plus or minus 4 percentage points. [...] Further, those with deep concerns about climate issues are much more inclined to hold climate scientists and their work in positive regard. This group is more likely than others to see scientists as understanding climate issues. Two-thirds (67%) of this more climate-engaged public trusts climate scientists a lot to provide full and accurate information about the causes of climate change; this compares with 33% of those who care some and 9% of those with little concern about the issue of climate change. About half of those with deep personal concerns about this issue (51%) say climate researchers’ findings are influenced by the best available evidence "most of the time." By the same token, those deeply concerned about climate issues are less inclined to think climate research is often influenced by considerations other than the evidence, such as scientists’ career interests or political leanings.
