However, some of the gases in the lower atmosphere acting like glass allow the incoming solar radiations (in the range of 300 – 2500nm) but do not allow the earth to radiate the heat back into space. In other words, these gases in the atmosphere are transparent to sunlight coming in but they strongly absorb the infrared radiation, which the earth sends back as heat. This result into the heating of the earth surface by this phenomenon called the “Green House Effect”. Greenhouse gases and Global warming...
