Air travel is a way for an individual to blow through a significant chunk of their individual annual carbon budget in a couple of hours - and it’s emitted high in the atmosphere where the warning effect is amplified. Globally it doesn’t look so bad because overall, few people use air planes. Among those who use air planes, it looks pretty bad. Also consider that those who advocate against excessive air travel also argue for the use of public transportation, walking and bicycling as a means to replace car travel. For long distance travel, the alternatives aren’t so obvious, that’s why aviation is such a concern.
