My thoughts at this early stage (note to self, it's only me reading this, so keep it simple):

* Most if not all heavyweight science institutions and publications support CAGW.

This alone means that us uneducated citizens really have to trust these people. We simply can't read the data and make good sense of it. That's why we have experts.

* It's not helpful shouting down doubters.

It gives the impression that the evidence is flimsy. There is also the fact that the public is being asked for significant money in counteracting CAGW. Most of us like reassurance that the money is spent wisely (though it almost never is).

* Only listen to genuine experts.

Forget over-inflated multi-millionaire jet-setters with Powerpoint shows. They're in it for fame and money.
