Though roughly 95 percent of scientists agree that climate change is caused by humans, you might not know it if you were learning about the environment in middle school or high school. In a recent randomized study of thousands of science teachers, a group of US researchers found that nearly a third of teachers tell students that the current observed trends in global climate change are "natural."
Published today in the journal Science, the results of the study reveal that science education on the subject is unevenly distributed. Teachers are all over the map when it comes to what they're teaching about climate change, with 30 percent telling students that "recent global warming 'is likely due to natural causes,'" and another 12 percent not emphasizing potential human causes of climate change. Additionally, 31 percent of teachers appeared to be giving students "mixed messages," teaching that Earth's climate changes could be caused by humans or by natural processes.
