So, how many more Priuses will the world have to buy to offset this Icelandic volcano?
Update: This reader may be a bit of a jerk, but he’s basically right:
uhm – so first us “planet Gore” people believe in doing a little
research and find out that the grounded planes in Europe prevented
significantly more CO_2 emissions than the Volcano caused:
Moreover, since you have actually written a column on the climate change
chapter in Freakonomics 2 – you should be aware that the Volcano dust
will reflect sunlight and thus further contribute to cooling.
So if you want to write a snarky, silly – but perhaps slightly less
ignorant – comment, maybe you want to ask how much _fewer_ Priuses we
need to buy (or how much more Hummers you get to drive…) because of
