Should be easy, considering they don’t exist to begin with. 

until they decide enforcement means no contrails at all and suddenly they’ve found a new and exciting way to economically ruin the country.

Contrails contribute to global warming and are completely avoidable.

Contrails are mostly water vapour that’s condensed due to the hot exhaust of airplane engines.

They are certainly not completely avoidable, they are likely inescapable without sacrificing significant fuel efficiencies (eg: all methods stealth fighters use to suppress or mask their exhaust heat signature)… which would negate any benefits to global warming.

P. s. I’m not going to watch a YouTube video that could be a few paragraphs of textual explanation, because it’ll no doubt be eight times longer than it needs to be for the benefit of more ad money or promotion in the almighty algorithm.

Pretty sad that your comment gets so much attention while dismissing a huge breakthrough in research.

Maybe we shouldn’t have to SMASH THAT LIKE BUTTON to have a discussion on the internet, or sit through an ad read for Brilliant or whatever

Do we seriously have to listen to people air their gripes about internet video anytime a link is shared? Jesus Christ.
