What the Scientific Debate Over Climate Change Looks Like: 97.1% Agreement

It is true that there is not unanimity in the scientific community over the role of humans in climate change. But with over 97 percent of scientists agreeing that warming is linked to human behavior, science is as close to unanimity as it's likely to get.
Researchers from a number of universities and institutes — including, we'll note, some that do advocacy work — looked at nearly 12,000 peer-reviewed studies released between 1991 and 2011 that contained references to global warming in their abstracts. The team was looking for whether or not the papers addressed the cause of warming; in other words, if people are to blame.
Of those 11,944 papers, the majority didn't take a position on causation. (AGW below is shorthand for scientific term: "anthropogenic global warming.")
But considering only those papers that did suggest a cause, the consensus was overwhelming. Of those, 97.1 percent indicated support for the idea that mankind is responsible for atmospheric warming, primarily through the emission of greenhouse gas.
As time has passed — and as indicators of warming have become more apparent — the number of papers addressing the topic have increased, as have the number of papers suggesting that humans are to blame.
