Does Global warming exist - Essay ExampleGlobal warming ordinarily occurs when greenhouse gas emissions such(prenominal) as carbon dioxide is throttleped in the atmosphere thus create a thickening blanket that traps the heat from the sun, making the planet earth to warm up constantly over a period of time (National Research Council (U.S.), 2010). There is clear evidence that there has been a marked change in the composition of greenhouse gases in the atmosphere that currently stands at 390 ppm and even higher levels mystify been recorded at 400ppm at Mauna Loa, Hawaii in May 2013. It can straightway be proven that the comely global temperature has undergone a change of about 1.4F in the give way one hundred years (National Research Council (U.S), 2010). While the American National Oceanic and Atmospheric constitution (NOAA) found that, the period between years 2000 and 2010 was the warmest on record with 2005 and 2010 being the warmest (Giese, 20113). Scientists also project that Earths average temperatures will raise between 2 and 12 degrees Fahrenheit by 2100 which will be pitch-black to human life and all the animal life on the planet earth (National Research Council (U.S.), 2011).The upgrade in the global temperature has been shown through the changes in weather and ultimately the temper of regions such as changes in rainfall pattern and intensity. The oceans, seas and glaciers have equally undergone changes while the oceans have become more acidic, the glaciers and ice caps on mountains and the Polar Regions have melted while the sea levels have risen (United States. (2010). These changes can be attributed to climate change have been due to human activities and natural variations in the weather and climate of a place. It is beta to observe that the earth goes through a natural cycle of cooling, warming that may be attributed to factors such as changes in solar system, and acts such as volcanic activity and these cannot be the only business re lationship for the rise in temperatures (U.S. Global Change Research Program and Karl, 2009). According to the National Research Council (U.S) (2010), the biggest apparent movement of the increase in the global temperature of the earth is the trapped greenhouse gases in the air that trap the fervency leading to heating. This has been proven using satellite technology to measure the fluctuations in the energy from the sun scientists have proven that the suns contribution is minimal as compared to human activities. The upshot of this is that the increase in temperatures currently experienced globally is due to the warming properties from greenhouse gases such as carbon dioxide that trap heat in the atmosphere. The increased concentration of carbon dioxide and other greenhouse gas emissions increase the totality of water vapor in the atmosphere that also aids in the trapping and retention of the surplusage greenhouse gas emissions. Because water vapor is a greenhouse gas, it leads t o further warming through a
