You can’t do anything about problems you don’t know exist, and you can’t prioritize systematically without some understanding of where the bottlenecks are. There’s no problem if some researchers exclusively focus their time on discovering and describing problems. Someone else can explore possible solutions. Someone else can try to plan/develop an implementation of each of those. Someone else can work on political advocacy to build support for one or another solution. Etc. It seems you have already brainstormed a few personal steps you could take to combat this problem at an individual level. But that isn’t going to cut it at a societal level. For that we probably need some combination of (a) less carbon-intensive but still convenient modes of transportation, (b) globally implemented carbon taxes [or the like] which force consumers to confront the true costs of their consumption, including plane flights, (c) large-scale public education campaigning, possibly including discouraging the public from traveling halfway around the world multiple times per year, etc.
