Geoengineering: Goldilocks effect to cloud seeding
Get this climate techno-fix right, and the effect is dramatic, Get it wrong, though, and you make the problem worse. So how do you get this to work as planned?

Who bears the cost of airline emissions?
"Aviation is today responsible for some 2% of the planet’s man-made CO2 emissions. But when the effects of nitrogen oxide emissions, water vapour, soot and sulphates, contrails and enhanced cirrus cloud formations are also factored in, the best scientific estimates put aviation’s overall contribution to global warming at 4.9%.
The International Civil Aviation Organisation (ICAO) has forecast that CO2 emissions from international aviation (about 60% of total aviation emissions) will grow from approximately 400 million tonnes in 2010 to 650 million tonnes by 2020. Unchecked, there may be a 274% increase in the fuel used by airlines by 2050, measured against 2006 levels.
Put plainly, the aviation industry bears a share of responsibility for the accelerated drought-flood cycle that climate change will bring to countries such as India." (emphasis mine)

The conversation here:
And what's more, purposely using fuels or additives known to ultimately exacerbate climate change e.g. through cloudiness, or increased aerosol generation, would not constitute geoengineering if it is perceived as being done with intentions other than geoengineering.
