Google is trying to solve contrails with AI (www.engadget.com)

Google, in collaboration with the UK government, has launched Operation Blue Skies, a groundbreaking project aimed at minimizing the environmental impact of contrails formed by aircraft. Conducted over the Shanwick airspace in the northeastern Atlantic Ocean, this 30-month trial will involve subtle rerouting of selected flights during the next two winters. With contrails contributing to approximately one-third of aviation's climate impact by trapping heat, the project seeks to determine whether strategic flight-path adjustments can significantly reduce their formation. Utilizing AI-powered forecasting models, Google will analyze atmospheric conditions to identify optimal flight adjustments. Air traffic controllers will be informed of these conditions to make vertical adjustments of up to 2,000 feet for about 1-5% of the 10,000 flights expected to cross the region during the trials. The initiative not only highlights the potential application of AI and machine learning in combating climate change but also represents a collaborative effort among various research institutions and governmental bodies, with Google contributing £1.4 million to the £5 million project budget. If successful, Operation Blue Skies could set a precedent for future sustainable aviation practices.
