Air traffic controllers will use AI-generated forecasts to advise planes flying over the Atlantic to adjust their altitude in an effort to reduce the climate impact of contrails, reports Madeleine Cuff PLANES flying across the North Atlantic Ocean later this year will be re-routed to avoid causing condensation trails, in a first-of-a-kind trial to address the global warming impact of contrails across an entire airspace. Starting in November, air traffic controllers managing the Shanwick airspace on the eastern side of the North Atlantic will advise planes to adjust their altitude to avoid creating fresh contrails. The controllers will be using AI-generated forecasts of atmospheric conditions from Google that predict where contrails will form. …
