If we didn't tie the acceptance of statements which can be supported or dismissed by evidence

  * climate change is a measurable effect

  * humans have a non-trivial impact on climate change

with and particular blame or course of action

  * The coal industry is *bad* for contributing climate change.

  * We must immediately reduce our consumption of meat and oil.

then I think we would have a lot people suddenly be in agreement about the facts.

Trying to shift the blame for disagreement to the people who are on the right side of the facts is mistaken. People are deluded on the facts because of a massive decades long propaganda effort. The left moving to the center hasn't brought the right to the center on any issue, it's just allowed the right to get even crazier.
