              THE EXTRAORDINARY SELECTIVENESS
              OF THE ATMOSPHERE





                  If the Sun’s radiation has been designed to support life on
              Earth, the atmosphere plays an important role in letting through
              it wavelengths in the right combination and at the right ratio.
                  In order to reach the Earth’s surface, radiation coming from

              space must pass through the atmosphere first.
                  If the atmosphere were not of a composition allowing it to
              filter through, it could be of no benefit. However, the atmos-
              phere has a special filtering property that lets beneficial radia-
              tion penetrate.
                  The atmosphere’s truly miraculous aspect is not that it lets
              radiation penetrate, but that it lets through only beneficial radi-

              ation—visible light and infrared radiation, while shielding us
              from other deadly types of radiation. Thus, the atmosphere is a
              crucial filter against cosmic radiation reaching the Earth from
              sources other than the Sun. Professor Denton explains:
                  Atmospheric gases themselves absorb electromagnetic radiation
                  immediately on either side of the visible and near infrared... The
                  only region of the spectrum allowed to pass through the atmos-
                  phere over the entire range of electromagnetic radiation from
                  radio to gamma rays is the exceedingly narrow band including
                  the visible and near infrared. Virtually no gamma, X, ultraviolet,
                  far infrared, and microwave radiation reaches the surface of the
                  earth.  43
