Google is trying to solve contrails with AI

Google and the UK government are collaborating on a project to test whether airplanes can avoid creating contrails. The project, called Operation Blue Skies, will conduct the trial over Shanwick airspace, which sits above the northeastern Atlantic Ocean. Contrails are the long white streaks in the sky left by jet engines. Most often created in cold, humid air, they form when water vapor condenses and freezes around aircraft exhaust. Researchers estimate that they contribute to about one-third of aviation's total climate impact.
