Some things I forgot to say

Here are some things that I forgot to say about biofuels and the IMF report:

I generally support ethanol in replacing MTBE as a fuel additive, but not much more. Roughly, the amount of ethanol that is produced today should be enough to replace MTBE in gasoline where it is needed (slightly more than 1/3rd of all gasoline in the US requires some sort of oxygenate like MTBE or ethanol). http://www.epa.gov/mtbe/gas.htm

As far as the IMF study goes, they said it would cost 0.6% of GDP to level GHG emissions off at 550ppm by 2100. It seems to me that 2100 is quite late. As far as I know, the IPCC suggests a leveling off to 450-550ppm GHG emissions by 2050.
