A comprehensive analysis of peer-reviewed articles on the topic of global warming and climate change has revealed an overwhelming consensus among scientists that recent warming is human-caused.

The study is the most comprehensive yet and identified 4000 summaries, otherwise known as abstracts, from papers published in the past 21 years that stated a position on the cause of recent global warming — 97 per cent of these endorsed the consensus that we are seeing human-made, or anthropogenic, global warming (AGW)
Led by John Cook at the University of Queensland, the study has been published 16 May, in IOP Publishing’s journal Environmental Research Letters.
The study went one step further, asking the authors of these papers to rate their entire paper using the same criteria. Over 2000 papers were rated and among those that discussed the cause of recent global warming, 97 per cent endorsed the consensus that it is caused by humans.
The findings are in stark contrast to the public’s position on global warming; a 2012 poll* revealed that more than half of Americans either disagree, or are unaware, that scientists overwhelmingly agree that Earth is warming because of human activity.
John Cook said: “Our findings prove that there is a strong scientific agreement about the cause of climate change, despite public perceptions to the contrary.
