For clarity, the main reason my for suggesting cloud seeding is that it can be used to build up greenland to a height where the air temperature is low enough to sustain the ice sheet. The could potentially reverse the catastrophic Greenland tipping point - which will unleash several metres of sea level rise over a few hundred years. Game over for London, Venice, Florida, New York, etc. if that happens. Worth a bit of jet fuel or a few rockets to prevent that, I'd argue.
