Blame cosmic rays not CO2 for warming up the planet
ethanol/methanol also suffer from storage probs, since they are anhydrous... they also provide less endurance and have a lower calorific value, but generally higher octane ratings.
Ethanol is non-corrosive, but will perish rubber seals (not neoprene though). Methanol is corrosive and will corrode most metals readily. which is a major prob with all modern cars as the fuel system it 98% metal.
The only advantage to using alcohols is generally you can run much high compression ratio's without detonation... and the hole re-newable energy thing though. I heard recently that if Australia converted to alcohol fuels overnight, the required crop to create enough ethanol would have to cover somthing like 90% of the area of australia or something rediculous like that...
