New Poll: 97% of Climate Scientists Think Planet Warming Caused by Humans
Do climate scientists disagree about global warming? Nope. A survey published in the Proceedings of the National Academy of Sciences shows that a whopping 97 percent of climate experts agree that global warming is "very likely" mainly caused by human activity.
Of the 1,372 scientists surveyed, nearly all agreed that it is "very likely that anthropogenic greenhouse gases have been responsible for most of the unequivocal warming of the Earth's average global temperature in the second half of the twentieth century."
The study found that the three percent of scientists who disagreed with the statement lagged in expertise when compared with their colleagues, based on publication and citation rates.
USA Today has created an interactive graphic that shows how global warming occurs.
