One way to stop the global warming of the earth atomosphere is the increase of the Albedo. This paper discusses four artificial ways to increase the Albedo : (1) to cut the sun light by putting screens between the earth and the sun, (2) to set up mirrors on the surface of the earth to reflect the sun light, (3) to float small solid particles in the air to reflect the sun light, (4) to float balloons in the air. Only the feasible way to increase the Albedo is the way (3). The way (1) requires too heavy screens. The way (2) requires too wide mirrors. The balloons of the way (4) have large diameters.
