Given the cooling that is reality, should these “cloudships” be implemented and be successful they wiould probably usher in a new Ice Age with attendant famine, etc.
Because clouds are reflective they can be used at night to retain heat. Farmer’s used to use smudge pots to create man-made cloud blankets that kept citrus trees from freezing. Clouds can be influenced to swing the surface temperature either direction. We can prevent an ice age or global warming with cloud control. We can’t influence the Sun, but we can influence clouds.
