'A Reflective Observation on Global Warming\r'

'Elizabeth Kolbert’s chapter 2 entitled â€Å"A Warmer jactitate” in her book â€Å"Field Notes From A catastrophe” is basically approximately the find of global heat and the developments in its cognizance. It also shows relevant data about certain factors that affect global warming.John Tyndall’s discovery of the ratio spectrophotometer in 1859 was the advent of the awareness in global warming.The function of the said device is to pit pursueance and transmittance of their light beam exhibited by the gases. Results of the tests showed that the gases commonly entrap in the air such as normality and oxygen did not absorb nor transmit whatsoever radiation. However, other gases such as carbon dioxide and weewee absorbed viewable and infrared radiation radiation (p.36).With these results, Tyndall stumbled upon a baffling and shocking truth that lead military campaign a worldwide sensation and concern in the following generations. Tyndall conclu ded that these gases contribute largely to the way the existence radiates and absorbs radiation from the sun. He thought of the line as a barrier that regulates the derive of radiation that enters the ground which affects its overall temperature. This notion was later cognise as the â€Å"natural babys room effect” (p.36).The sun, earth and many hot bodies emit radiation and the amount of radiation is now proportional to its temperature. This is further explained by the Stefan-Boltzmann Law which sates that the temperature raised to the fourth power is directly proportional to the radiationemitted by the body. The role of the greenhouse gases is to absorb selectively the radiation from the sun and allow visible radiation to penetrate the melodic phrase. The earth’s infrared radiation, on the other hand, is absorbed by the greenhouse gases and is emitted partially into space and partially back to earth.This phenomenon regulates the temperature on the surface of the earth. After Tyndall crystalliseed away from an overdose of a sleeping drug, Arrhenius continued what Tyndall left unfinished. Arrhenius studied the effectuate of altering carbon dioxide levels in the air and he found out that rising carbon dioxide levels allow for enlarge the earth’s temperature, hence, he coined the show â€Å"to stand firm under a warmer thresh about” to the next generations (p.42)Interest in the climate change mellowed down after the death of Arrhenius. However, in the mid(prenominal) 1950’s, there was a rebirth in the awareness of global warming and this was due to Charles David Keeling, a chemist. The results of his research in the atmospheric carbon dioxide levels in the atmosphere or the â€Å"Keeling Curve” showed that the carbon dioxide level join ons as time increases.The results were devastating as years pass by. The Keeling curve also showed that the carbon dioxide level in 2005 was 375 parts per million and wi th this terrifying rate, it exit increase to 500 parts per million by the spunk of the century which will greatly affect the temperature of the earth and will make us feel the encompassing effects of global warming (p.44)Global warming threatens us to extinction. This is caused mainly by industrialization and we must stop, or if not, control the facelift of carbon dioxide levels in the atmosphere to save the future generations. Global warming will cause the polar and ice glaciers to melt that execute to a rise in sea level. This rise will flood coastal regions and other work masses. There is also an expected change of pelting patterns across the globe that will greatlyaffect food crops and will be a major setback in food production in many nations. With the increase in temperature, plants and animals will be forced to live in cooler areas and those who are unable to fit will be doomed of extinction.  (Global Warming, Encarta)\r\n'
