Heh. Anyway, catalytic converters don't interact with global warming at all. Catalytic converters don't have any effect on CO2, if anything they make it worse by requiring stoichiometric mixture instead of lean. The purpose of catalytic converters is to reduce smog. Airplanes, in principle, spend most of their time flying at altitude and over rural areas where smog is not a factor. By far the biggest reason not to have one is that leaded gas fouls catalytic converters and so with typical avgas they would quickly just turn to heavy, expensive junk. I suppose if you guaranteed to only ever run mogas you could consider it, but still you would just be adding weight, cost and complexity for very little actual benefit.
