By increasing the abundance of these gases in the atmosphere, humankind is increasing the overall warming of the Earth s surface and lower atmosphere, a process called global warming.. The figure below illustrates the radiation balance and the role of greenhouse effect. Illustration of the Earth s radiative balance.
These extreme temperatures are caused by the absorption of the sun's shortwave ultraviolet radiation. This radiation penetrates the upper atmosphere, stripping atoms of their electrons and giving them a positive charge. Electrically charged atoms build up to form a series of layers within the thermosphere. These charged layers are often referred to as the ionosphere, which deflects some radio signals. Before the modern use of satellites, this deflection by the ionosphere was essential for long distance radio communication.
