9 in 10 scientists think climate change is real

Nearly 92 percent of surveyed scientists, however, believe the world is warming and humans are to blame, according to a Purdue University study released last week.

The study surveyed nearly 700 non-climate scientists across an array of disciplines at Big Ten universities. Previous studies have shown 97 percent of actively publishing climate scientists believe humans have an impact on warmer climates, according to NASA.

"We keep seeing non-climate scientists in the media as 'the other side,' saying climate change isn’t happening," said Linda Prokopy, a professor of natural resource social science and one of four authors of the study. "And we thought, 'Well, are there really a lot of scientist out there who don’t believe in climate change?'"
