SInce we’re talking climate change I think we should bring back airships for short-haul flights. The fact it floats with little effort means less fuel is needed.

I figured in continents like Europe, for example, building an extensive high speed railroad would be far more effective.
Last summer I did a trip through Western Europe by train and I went from Basque country to Copenhagen without any major problems. I did 3800 km in total by train. If Europe takes trains serious, they could have a high speed connection to everywhere.
The longest train travel you can do in the world (as of 2021) is from Lagos in Portugal to Singapore. It take something like 21 days and multiple train changes though but still.
