Interesting piece. The idea the strikes me as very important is the role of skepticism or more specifically not accepting evidence until it is proven to the best level we are capable of today.

Some of the heros of science were skeptics. Galileo had the misfortune of clueing into the fact the Earth revolves around the sun and not the other way around. For this he was imprisoned. Today we accept his contribution to our knowledge base without doubt.

So if people want to be skeptical about this new-fangled idea of man created massive atmospheric effects perhaps it no different than Galileo's reception to his proposal causing us to rethink ancient beliefs. Human's do fundamentally hate to change their beliefs or behavior. But at some point the preponderance of evidence does have to be considered and only a jury willing to really study it will be able to make that call. So go out, invent a telescope, make endless observations, produce undeniable results and get back to us on this "hoax"...
