Climate gases or Greenhouse gases

Climate gases or greenhouse gases (GHG), are gases that absorbs and emits radiant energy and are the gases that causes the greenhouse effect. The primary greenhouse gases in the atmosphere are water vapor, carbon dioxide, methane, nitrous oxide and ozone. Without greenhouse gases the average temperature of the earth should be around -18 C instead of the present 15 C. Since the industrial revolution human activities has significantly increased the atmospheric concentration of carbon dioxide which is the cause of the greenhouse effect with increased temperatures on our planet.
