That YouTube Short seems to be a valid one. It's by someone who (according to his own words) has a PhD in atmospheric physics. Basically, he says that contrails causes global warming by preventing heat from escaping from Earth, and that contrails are mostly only formed when a plane flies through a cold humid patch. By simply re-routing planes around these cold patches, the contrails could be reduced.

By simply re-routing planes around these cold patches, the contrails could be reduced.

And routes now are generally chosen to be the most fuel-efficient, subject to regulatory constraints such as avoiding overflight of areas of high population density. So any alternate path will be longer and burn more fuel.

As said in the video everyone refused to watch, it doesn’t require all new routes but occasional 1-2% course deviations or altitude changes for a minority of flights. It’s also claimed that contrails have far, far more warming effect than any additional carbon that might be emitted by this. But hey, he posted it in a video so FUCK HIM, RITE?
