In viral Turning Point USA video, Candace Owens and Charlie Kirk falsely claim there is no evidence of global warming and scientists don’t know the cause

VERDICT

Climate scientists agree that human-caused greenhouse gas emissions are primarily responsible for climate change, contrary to claims in Clear Energy Alliance video

CLAIM
The scientific consensus on whether global warming is human caused is not 97 percent, it’s less than 1 percent. There is no way to measure the human impact on climate change.
