Around 2.4% of all global green house gas emissions, but responsible for 5% of global warming [1]. I wouldn't call it minuscule. I think one of the reasons that aviation is so often in the spotlight in discussions about climate change is the existence of greener alternatives. Of course, those can't replace all flights, but they don't have to. Add to that the fact that air travel has exploded in recent years before Corona, and you certainly have to ask yourself whether taking five weekend trips a year from Zurich to Hamburg really improves our standard of living so much that we should put up with the downsides of it. Personally, of course, I also like to travel and I think flying is a great invention that brings countries and people closer. Nevertheless, you have to be a bit critical about whether every flight is really necessary.
