4% of global warming to date. Flying will still be possible (and not uncommon) in a net zero world. Maybe americans will have to take the train to see their relatives, but they could just DACCS if they love TSA controls so much.

Like I said, it counts almost double. Aviation makes up 4% of the impact when 90% of the global population isn't even flying in a year. Traveler numbers are tiny compared to other modes yet it causes a 4% chunk.

Aviation is outright terrible in its impact compared to rail, on corridors where both are an option. Of course, for many travels, only aviation is in option. That is a reality but doesn't make aviation any better.

Agreed on all points.
