The average increase in temperature of the earth is called global warming. Global warming wasn't an issue before, but nowadays it's a burning issue. For the past 100 years, the temperature of the earth has increased by 0.74 degrees. The reason behind the global warming is green house gases. The greenhouse gases like carbon-dioxide, methane, nitrous oxide, hydro-fluoro-carbons, sulphur hexafluoride and water vapour are covering the earth's atmosphere more than required. These gases act as a blanket for the heat energy reflecting back to the space and heat the earth's atmosphere more and more resulting in extreme temperature pattern. If the atmosphere is without greenhouse gases, all the energy that comes from the sun radiates back to the space, resulting the earth as a cold ball. However, if the greenhouse effects becomes stronger, more of the heat than needed gets trapped, and the earth becomes less habitable for humans, plants and animals.

Different climatic changes like climatic imbalances, draughts, storms, wildfires, hurricanes, rainstorms, sea level increment, extinction of mammals and different typical problems have become the common news nowadays (Americans college of physicians, 2007). Every single day is becoming hotter and hotter, which increases in chance of daily deaths and spreading of diseases. There is great chances of food poisoning and breakdown of infectious and communicable diseases. Developed countries could provide health services to some extent, but the undeveloped and developing countries will have the adverse affect on their health. Developing countries are in more risk of catching health problems as health standard are variable with developed countries. Extreme temperature also results in population displacement in marine life (NASA Home, life on earth). The carbon-dioxide when mixed with water in presence of air changes into carbonic acid changing the chemistry of water in seas and oceans. Mostly northern and...
