Healthy skepticism is a useful thing, John. No doubt. I often go against the general flow myself on any number of things. Like who planned the destruction of the WTC and carried it out, for example... ;-)

That too can be a pitfall.

What do we have to lose by reducing CO2 emissions? (in the long run, I mean)
