Of more than 4,000 academic papers published over 20 years, 97.1% agreed that climate change is caused by human activity.
Authors of the survey, published on Thursday in the journal Environmental Research Letters, said the finding of near unanimity provided a powerful rebuttal to climate contrarians who insist the science of climate change remains unsettled.
The survey considered the work of some 29,000 scientists published in 11,994 academic papers. Of the 4,000-plus papers that took a position on the causes of climate change only 0.7% or 83 of those thousands of academic articles, disputed the scientific consensus that climate change is the result of human activity, with
the view of the remaining 2.2% unclear.
The study described the dissent as a "vanishingly small proportion" of published research.
"Our findings prove that there is a strong scientific agreement about the cause of climate change, despite public perceptions to the contrary," said John Cook of the University of Queensland
, who led the survey.
