evidence: However, the degree of consensus was higher among scientists with greater climate science expertise. Among actively-publishing climate scientists, 97.4% agreed that humans were causing global warming. [...] Our research, published in Environmental Research Letters, found that the scientific consensus had strengthened even further since 2009. Among Earth scientists overall, there was now 91.1% agreement on human-caused global warming, an 11% jump from the 80% figure in 2009. [...] This strengthening consensus among the scientific community – even among traditionally sceptical fields – is also reflected in other parts of society that have in the past been resistant to accepting climate science.
