A study of 88,125 climate change studies found that more than 99.9 percent of peer-reviewed articles agreed that the changes were largely man-made.
The present study updates a 2013 study that found that 97% of studies conducted between 1991 and 2012 concluded that human activities had caused climate change. Now in this research study Examined Which were performed in the period from 2012 to November 2020. The researchers wanted to see if the scientific community’s view of the origins of climate change had changed.
“Certainly we can say that the consensus of the scientific community has now reached more than 99 percent, leaving no doubt about the reality of climate change affected by human activity,” said Mark Linas of Cornell University, who co-authored the article.
“It is vital that we take on the fundamental role of greenhouse gas emissions so that we can quickly adopt new solutions, as we are already witnessing the catastrophic effects of climate change,” said Benjamin Holton, dean of Cornell University School of Agriculture and Life Sciences and co-author of the paper. “We are focused on businesses, people and the economy.”
Despite such results, the general public and politicians still believe in misconceptions and claim that the scientific community still disagrees on the root cause of climate change. The Pew Research Center found in 2016 that only 27% of American adults believe that almost all scientists believe that climate change is caused by human activities.
To do this, the researchers first reviewed 3,000 randomized studies between 2012 and 2020 and found that only four studies were skeptical about the impact of humans on climate change. They then developed an algorithm to look for keywords such as “solar”, “cosmic rays” and “natural cycles” that were likely to be present in conflicting articles. In the end, the surveys showed that only 28 articles directly doubted the origins of these changes, and all of them were published in small journals.
