Scientists are figuring out the keys to convincing people about global warming | Dana Nuccitelli

Understanding the greenhouse effect, the expert consensus, and that humans are causing global warming are gateways to support for climate policies

The latest survey data from Yale and George Mason universities underscores the partisan divide on climate science denial - 73% of Americans realize that global warming is happening, including 71% of liberal/moderate Republicans, but the average is dragged down by the mere 47% of conservative Republicans who answer this question correctly. On the bright side, this is a big improvement from the 28% of conservative Republicans who realized global warming was happening just two years ago.

Similarly, 56% of Americans realize global warming is mostly caused by humans, including 49% of liberal/moderate Republicans, but the number is again dragged down by the 26% of conservative Republicans correctly answering this question.
