If you shift a route to avoid making contrails and end up on a longer or more turbulent route what is the net benefit to the climate? For example if a plane ends up using more fuel on a longer route to avoid a cold area where contrails could be made or ends up on a route with more headwinds or turbulence.

Is this a bit of green washing?

This is not what I was envisioning for major AI breakthroughs

It can hack into companies and exploit anything, but beyond that, forget the medical breakthroughs and real climate solutions, we’re tackling “sky graffiti”. Here I was, an ignorant dolt, unawares that we even had a major “sky graffiti” problem.

Yeah, let's use a computationally heavy task that contributes to burning coal and gas releasing CO2 into the atmosphere to reduce a slight fraction in emission so we could pat ourselves on the back.
It is not a “slight” reduction in emissions, it’s absolutely huge! About half of the aviation industry’s total impact on global warming is due to contrails! This is 1-2% of all human caused warming across all industries.

(Though slight caveat for any nit-pickers. The warming isn’t related to emissions. The contrails essentially create a blanket that traps heat in the earth’s atmosphere - the BBC article linked mentions this)
