Glitter belt: atmospheric reflectors to reduce solar irradiance

A method is described to reduce Global Warming by reflecting solar irradiance. Thin reflective sheets are flown under control in the upper atmosphere above Earth, in contrast to reflecting from Space orbits or the ground. The high altitude enables nearly total reflection. Two general embodiments use translational and/or rotational motion of the sheets to hold sheets stretched while providing aerodynamic lift, while a third uses buoyant aerostatic lift. During the daytime solar power is used. During the night the low wing loading of the sheets facilitates gliding flight without descending into controlled airspace. Sheets can be arrayed to increase aspect ratio and decrease induced drag. By following the summer sun, effectiveness is increased. A swarm of reflectors around the south Polar Circle can reduce summer melting of ice enough to reverse the rise in sea level.
