The greenhouse effect refers to circumstances in which the short wavelengths of visible light from the sun pass through a transparent medium and then are absorbed, however the longer wavelengths of the infrared re-radiation from the heated objects are unable to pass through that transparent medium. The trapping of the long wavelength radiation causes more heating and also a higher temperature. Besides the heating of an automobile by sunlight through the windshield and the namesake example of heating the greenhouse by sunlight passing through sealed, transparent windows, the greenhouse effect has been widely used to describe the trapping of excess heat by the rising concentration of carbon dioxide in the atmosphere. The carbon dioxide strongly absorbs infrared and does not allow as much of it to escape into space. Greenhouse gases are really important for the life on earth as we know it. The reason for that is the fac that they keep the planet 's surface warmer than it otherwise would be. However, as the concentrations of these greenhouse gases continue to increase in the atmosphere, the Earth 's temperature is climbing above the previous temperature levels.
According to the data from NOAA(National Oceanic and Atmospheric Administration) and NASA(National Aeronautics and Space Administration), the average surface temperature of the Earth 's has increased by about 1.2 to 1.4ºF in the last 100 years. Eleven of the last twelve years rank among the 12 warmest years on record…
