There is another choice: geoengineering.[1] Instead of reducing emissions to slow down global warming we actively remove these pollutants from the enviroment around us. I'm not going to comment on it's efficacy though.
As for reality, the problem is that nobody can be precipitous. Those who go with more expensive fuels will immediately put a burden on the local economy and throw themselves out of the competition.
The only thing slightly more horrifying than geoengineering is letting global warming just happen, so I guess you are right. To make what I said more precise, I am looking for a choice that doesn't do dangerous experiments with the earth's climate. Geoengineering does such experiments, but it may be the default choice of inaction we are taking right now.
