It would be very unwise to make flying more attractive as long as the planes are injecting fossil CO2 straight into the upper atmosphere. This makes the emissions 2-4x more potent greenhouse gases than CO2 emitted from the ground.

We should be in a hurry to implement disincentives for air travel.

Disincentivizing air travel? Do we have a viable alternative to get me from New York to London in less than 5 days?

There are more important things in the world than keeping your current ticket price when flying from New York to London.

I'm all for paying more in the interest of environmental protection, but again: is there a viable alternative?

Is reversing the democratization of international travel, which I would argue has been, proportionally, much more of a force for good economically and socially than it has been an instrument of environmental destruction, really the best answer we've got?

[zurn]

Seeing the world is well possible without airplanes if you take out the 5 day trip length! Going for short trips every now and then is very wasteful.

But yes, cutting down on flying will have downsides. As will many other compromises we must do to get CO2 down.
