Global Warming-Killing Earth’s Age

Global Warming is defined as the increase in the average temperature of Earth’s Atmosphere. Since 1970, most of the increase has been in the oceans, which is about 90%. Global Warming also refers to the increase in temperature of the Earth’s surface. Since the year 2000, the surface temperature has increased about 0.8 0 C, which is about two third of the increase, when compared to 1980. Earth is getting warmer and warmer when days pass by. The main cause for the Global Warming is the increase in the concentration of green house gases which is being let out by the activities of human beings. A study has shown that the main reason for Global Warming is the increase in the production of Carbon dioxide from Cement production, fossil fuel, and deforestation. A report in 2013 states that, human is the main cause of the Global warming which lead to the reduction in snow in Antarctic and Arctic regions, which paved way to the increase in the sea level. This effect will include increase in sea level, expansion of subtropical Deserts. Warming is expected to be higher in the Arctic regions. This has a lot of effects which will create lot of changes in human life; like heavy rainfall, heat waves, ocean acidification, and extinction of some species. Emission of green house gases have increased about 2.2% from 2000-2010. In Earth, the natural amount of green house gases give us about 33o C, so without these gases Earth would be below freezing point. The major green house gases are carbon dioxide which is causing 10-25%, while water vapor is causing about 30-70% of the effect. Methane has about 5-10% effect, and ozone which has 3-7% effect. Since the industrial Revolution, Human has increased the quantity of green house gases. According to a study in 2007, the amount of carbon dioxide and methane have increased about 148% and 36% since 1750’s. The burning of Fossil fuel has produced the maximum amount of co2 in the past 20 years, while...
