Climate research nearly unanimous on human causes, survey finds
Of more than 4,000 academic papers published over 20 years, 97.1% agreed that
climate change is anthropogenic
'Our findings prove that there is a strong scientific agreement about the cause of climate change,
despite public perceptions to the contrary'.
A survey of thousands of peer-reviewed papers in scientific journals has found 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.
Public opinion continues to lag behind the science. Though a majority of Americans accept the
climate is changing, just 42% believed human activity was the main driver, in a poll conducted by
the Pew Research Centre last October.
"There is a gaping chasm between the actual consensus and the public perception," Cook said in a statement.
