New procedure to reduce global worming ? -Answer please .?

To reduce global worming we have to block or to change direction of the incoming photon(electromagnetic wave) towards the earth's surface so that these photon could not reach the earth's surface . The photon have to p the atmospheric air of the world to reach the earth's surface . The path of any electromagnetic wave changes with change in the density of the medium by which it pes through . So the path of incoming photon towards the earth surface may be changed if the density of atmospheric is changed . we can use sound wave for this purpose . When sound pes through air ; the air is divided into many layers of different density . Suppose we plase a very high powerful and high frequency sound sourse at some height(about 150m) from the ground . When the sound source start producing sound wave of high frequency the atmospheric air above the sound source will be divided into many adjucent layer of different density . So the incoming photon can change direction or even be reflected
