Global WarmingGlobal warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a change that is believed to be permanently changing the Earth's climate. Even though it is an ongoing debate, it is proved by the scientists that the planet is warming.The 29th century is experiencing a continued increase of Earth's mean atmospheric temperature by about 1.4 degrees F and about two thirds of it occurring since 1980. This is global warming is affecting the nature's balance and has a huge impact on life like continued heat waves, and sudden occurrence of storms and floods. Don't we see time to time the epidemics that are devastating to human life and the flooding of the farmlands that puts economy in a deep hole?Scientific evidence indicates that since 1950, the world's climate has been warming, primarily as a result of emissions from non -stop burning of fossil fuels and the razing of tropical forests. Since the industrial revolution till this day, there is a constant emission of the carbon into the atmosphere, everything we do we leave carbon footprints. It is a man made cause of the global warming. The global emissions jumped 3 percent in 2011 and are expected to jump another 2.6 percent in 2012, researchers reported.The greenhouse effect is a process by which the greenhouse gases absorb thermal radiation; these are then reradiated in all directions. But when some of these radiations come back to the surface and lower atmosphere, it causes increase in the average surface temperature leading to global warming.Global warming CausesThe causes are many of which the main culprit is the increase in the greenhouse gases that is produced by burning fossil fuel and deforestation, thus intensifying the greenhouse effect leading to global warming. The four main contributors of the greenhouse effect are, water vapor, carbon...
