Can AI make the future of flight more sustainable by accurately predicting contrail forming regions so pilots can choose better routes? Contrails (those fluffy, white clouds you sometimes see behind airplanes) are surprisingly responsible for about 35% of aviation’s global warming impact. Contrail avoidance could be the most cost-effective way to mitigate aviation’s climate impact. Learn more about this research at: [ Ссылка ]
