99.9% of scientists agree on human-caused climate change

“Our study helps confirm that there is no remaining scientific uncertainty about the urgency and gravity of this task.”


According to a new study by Cornell University scientists, 99.9% of scientists agree the climate crisis is caused by humans. 

The scientific community’s level of certainty on humans’ causation of climate change is now on par with its agreement on evolution and plate tectonics, claims EcoWatch

“We conclude with high statistical confidence that the scientific consensus on human-caused contemporary climate change—expressed as a proportion of the total publications—exceeds 99% in the peer reviewed scientific literature,” says the study. 

This research updates and expands a 2013 study that showed 97% of peer-reviewed papers published between 1991 and 2012 supported the theory of anthropogenic climate change (ACC)—the notion that human activity was causing and exacerbating global heating, reports Common Dreams

Even with this data, one-third of Americans continue to deny human-caused climate change is an issue. The fossil fuel industry has a lot to do with the influence of climate change denial.
