I think that's a great talking point, but the fact is most people don't know what they don't know about this issue. You can't have a meaningful discussion with someone who doesn't know enough about it to figure out why "Methane triggered runaway climate change" may be a reasonable point of debate, but "CO2 reflection of infrared light causes increased warming" is not.

And for the most part, people don't want to educate themselves on this issue because you end up being either completely worried about what is happening and discouraged about the future, or you end up having to start examine critically many other points of Conservative ideology which can turn into alot of introspection and work that most people don't want to do.
