Global Warming and Greenhouse Gases – Civilsdaily

Global WarmingRole of Green Houses GasesGreenhouse GasesGlobal Warming Effect of A GHG and Global Warming PotentialShort Lived and Long Lived Climate ForcersSun is the source of all energy and all life on earth. Sun emits energy in the form ofshort wave radiations(high energy i.e shortwave)- 1. A part of which is reflected back by clouds, aerosols, atmosphere 2. A part passes through the atmosphere to reach the earth’s surface which emits it back in the form oflongwave radiation – Infra red (low energy, long wave) which warms the atmosphere and thus there is no net addition to earth’s temperature Note here that, at night when earth would be the net emitter, temperature would reach dangerously low levels.
