Some rather compelling arguments that maybe we're focusing our efforts 
on the wrong problems, or at the very least CO2 is a problem for 
reasons other than what everyone has been telling us it's a problem 
for.

Kind of makes you doubt everything you hear anywhere, since it's 
(including this) almost always presented by someone with such a strong 
agenda that they're really inventing science to support their arguments 
rather than the other way around. What's even more scary- I think about 
all the research I've done as a scientist and the Powerpoint 
presentations I've put together to try to make it look good... it's so 
easy to do. But you can't ignore everything you didn't do yourself and 
bury your head in the sand.  Quite the conundrum.
