I wrote this essay for my friend... But I didn't cite the sources and stuff, I hope that's okay.....Think about a time when your car was parked in the middle of a parking lot, in the middle of the day. The minute you opened the car door, you must have felt currents of hot air blowing past you. The moment you sat down, you might have felt as if your car was radiating heat! This is a small,yet effective example of a process called the GREENHOUSE EFFECT. This effect involves a certain bodyof matter, be it a car, or a green house in which plants are grown, or the earth itself, absorbing heat or radiation from another body, in our case - the sun. In case of the car, the glass enables the absorption of the heat, and traps the heat inside, and does not let it out. Similarly, the earth's atmosphere contains certain gases called GREENHOUSE GASESsuch as Carbon Dioxide or water vapor or Ozone or Methane, whichabsorb the radiations we receive from the sun, and trap the heat from it inside.

The more greenhouse gases in the atmosphere, the more the heat gets trapped, the more the temperature rises. This phenomenon of increase in the average temperature of the Earth'snear-surface air and oceans is called GLOBAL WARMING.So, what if the temperature rises? Due to global warming, there are serious, profound consequences that occur. These include:1. Increased evaporation of water, which would increase the amount of water vapor (a green house gas) in the atmosphere, making the process of global warming even worse.2. Heightened melting...
