Thanks for making dialogue possible!
Cover story. Geoengineer with jet fuel? I think the orders of magnitude are too far apart for that to even be possible, physically. I figure you'd need about as many planes as there is sky, and that's before hypothetical geoengineering substance is bought into consideration, which would have to be carried in said planes. Of course, and separately, the burning of jet fuel is part-contributor to changing the chemical composition of our atmosphere.
What you up to anyway, how's your day going?
