American Airlines and Google said Thursday that they significantly reduced the climate impact of some of the airline’s flights using an AI-based forecasting tool to help prevent contrails. When airplanes fly through cold, humid areas, it can create heat-trapping clouds. Google is using artificial intelligence to predict where these condensation trails, or contrails, will likely form if planes pass through. American Airlines added the forecasts to its flight planning system on a trial basis, to show optional routes to go around these areas or change altitude. American Airlines and Google say this could be one of the most cost-effective, scalable climate solutions available in aviation now. The industry is under growing pressure to address climate change.
