We've each looked up and seen the achromatic lines trailing down craft successful the sky.
Known arsenic contrails, these icy clouds lend to clime change, and scientists person been trying to enactment retired however to halt them.
Now, a £5m UK proceedings volition trial whether AI tin help, by predicting wherever warming contrails are apt to signifier and getting planes to debar those areas.
The 30-month Operation Blue Skies task brings unneurotic Google, the UK government, the Met Office, aerial postulation power supplier National Air Traffic Services (NATS) and world researchers.
It volition absorption connected the Shanwick Oceanic airspace successful the eastbound fractional of the North Atlantic corridor which accounts for astir 5% of planetary contrail warming.
Contrails are made erstwhile the blistery exhaust from craft engines meets the acold aerial astatine precocious altitude, creating crystal crystals.
Many vanish quickly, but successful peculiarly acold and humid conditions they tin persist and spread, forming clouds which trap vigor that would different flight from the Earth.
Dr Paul Hodgson, Google's method pb for Operation Blue Skies, told the BBC's Tech Life programme his five-year-old has a much colourful statement for the achromatic lines - "sky graffiti".
"We deliberation that contrail warming is liable for thing similar a 3rd of each aviation clime warming," helium said.
Dr Hodgson acknowledged determination was uncertainty astir the precise figure, but said scientists were assured it was "either rather a ample occupation oregon a precise ample problem".
The task besides comes arsenic the authorities backs enlargement of UK airports, raising the wider question of whether tech solutions tin sufficiently trim aviation's biology interaction arsenic request for flying grows.
Google is besides 1 of galore large tech companies spending billions connected new information centres - the giant, power-hungry banks of machine chips which powerfulness AI - which environmentalists are acrophobic volition lend adjacent much to clime change.
