I agree with you.  My question was prompted by the highlighted quote in the New 
Yorker article that neither Levitt nor Dubner had any training in "climate 
science," the implication of which is that Levitt/Dubner's policy 
recommendations regarding climate change should not be given serious 
consideration or serious consideration compared to the policy recommendations 
of someone trained in "climate science."  It appears that Levitt/Dubner did 
exactly what you recommend -- they spoke with climate scientists, engineers, 
etc. and others with technical knowleldge, generally informed themselves 
regarding the technical issues, and then advocated a policy in the political 
sphere consistent with their values.  Therefore, you and I should be able to 
agree that any criticism of Levitt/Dubner based upon their lack of a climate 
science training is a logical fallacy.

My follow up point is that if you (the generalized you) somehow believe that 
Levitt/Dubner's technical understanding of climate science is a 
misunderstanding rooted in their lack of technical training (i.e. they did not 
have the skill and capacity to make an informed judgment and understanding of 
the technical material and issues), then you have the philosophical dilemna of 
explaining how someone with a similar lack of  technical training could know 
that Levitt/Dubner's understanding was wrong (or right), and the related 
philosophical dilemna of knowing who was an expert and whether the claimed 
expert was truly knowledgeable or a quack.  I believe you can avoid these 
philosophic dilemnas if you avoid the logical fallacy made by the author of the 
New Yorker article.
