During the 9/11 aircraft grounding, climatologists had a pretty unique chance to measure temperature variance compared to historical data.
Just the few days of data showed that days became warmer and nights became cooler. I pretty much had no idea that just trails could impact weather so noticeably until I read up on this experiment.
As a european citizen I’d vote for all subsidies that go towards intra-European air travel to go towards railway traffic.
The US should so something serious about plane travel as well. At least we have the excuse of completely separate governmental entities that built different railway infrastructure. The US is probably lacking behind China who practically just began connecting their nation through high-speed railways.
