AUSTIN (KXAN) – Whether humans are responsible for climate change is an issue that the scientific community largely agrees on, but new data suggests that consensus has become almost unanimous.
ONE examination back in 2013 found that there was a 97.1% scientific agreement that climate change was caused by humans. The study looked at peer-reviewed scientific literature to identify skeptics of man-made climate change compared to articles where there was no skepticism.
Although 97.1% are still the vast majority on the subject, what about the remaining almost 3%?
A new recent study took a fresh look at whether the scientific consensus had changed. Using 88,125 climate-related articles published since 2012, researchers analyzed them to determine if there were skeptical words or narratives against the man-made climate change consensus.
The study was conducted in two ways.
First, 3,000 of the 88,125 papers were randomly selected and examined to determine the skeptical content of any man-made climate change.
Second, the entire data set of 88,125 was analyzed for keywords believed to be skeptical of climate change.
Of the 3,000 samples taken, a total of 4 papers man-made climate change were skeptical. That means about 99.86% of the sample of climate-related papers believed in humans caused climate change.
Looking at the entire dataset of 88,125 papers, 28 of them were “implicitly or explicitly” skeptical of man-made climate change. This corresponds to a 99.96% scientific consensus on man-made climate change.
The recent study published on October 19, 2021 reached the following conclusion:
We conclude with great statistical confidence that the scientific consensus on man-made simultaneous climate change — expressed as a proportion of total publications — exceeds 99% in peer-reviewed scientific literature.

Although researchers are increasingly convinced, elected officials still have something to do.
ONE Gallup poll from April 2021 found 109 representatives out of 435 and 30 senators out of 100 do not believe that humans are the cause of climate change.
