Production of white reflective paper sequin is easy as a breeze to cover 1/2 of the globe.
But I was thinking that since it will stay in orbit for 1 to 2 weeks. I was wondering about putting some sort of styrofoam like those plastic peanuts used in packaging. It is reflective but as it is burned in reentry perhaps the burning can yield a new gas that further reflects and cools the Earth. Not sure of the end product of burning paper as reentry and whether that will add more greenhouse gases. So that as it cooled Earth for 2 weeks it now adds to warming.
So I wonder if there is a petroleum type product that reflects and once burned on reentry that the molecule further reflects.
