Thanks! It's hard to ask for evidence in advance (and probably mildly contrary to the scientific spirit :) ), but at the very least it will have to explain lots of seemingly contrary evidence (or show flaws in _all_ those studies). update: I should also mention that I'm fairly trusting of at least some of those studies, since I know some people involved in them and they're both smart and trustworthy... Also, I'd be very surprised if CO2 was completely innocent. There's actually a theory going around that land use may be a contributing factor to climate change along with CO2: a forest absorbs heat differently than a crop field which is different from a city. This theory demonstrates that CO2-based AGW isn't either-or.
