Global Warming: The Controversy And Its Impacts
The earth has been around for billions of years and many issues in our time as a species have risen up. One matter that has come up is the issue of global warming or climate change. This conflict has been around for many years, but has started to get worse every year, since the United States and other countries have been emitting carbon dioxide into the earth’s atmosphere. Global warming is an urgent issue; moreover, there exists a controversy on whether humanity or nature is the cause, and the scientists who consider this a serious matter are entirely correct because humans are at fault. For the past couple of decades, researchers and scientists have gone head to head in attempting to figure out if global warming does exist. Some people argue against the point and some people may support it. The facts supporting human responsibility are there; however, some people do not tend to believe them, while others do. Professor Ian Pilmer, a geologist and professor of earth sciences, tries to convince people that nature is the main cause of global warming, and he uses his authority to create this false impression to force people into quick judgments. He also makes a hasty generalization in stating that “global warming and a high CO2 content bring prosperity and lengthen your life (Eggleton 171).” Pilmer thinks that just because the air people breath is made up of carbon dioxide and that it is good for one’s body, is a quick personal judgment. Llissa Ocko, on the other hand, who is a High Meadows Post-Doctoral Science Fellow at EDF gets straight to the point when she states that, “scientists are more confident than ever that humans are responsible (“How”).” Although many scientists are scholarly individuals, there exist so many different scientific viewpoints on the topic that it becomes difficult to know whom to believe. The statements before are only of modern scientists; however, some scientists from the 1800’s have argued the same viewpoint: global warming is a byproduct of humans, not nature itself. For example, in the year 1864 a Scottish physicist named James Croll made a statement saying “earth’s orbit could trigger ice ages by changing how and where the sun’s energy fell on the planet.” In 1896, a Swedish chemist named Svante Arrhenius was the first of all scientists to create a hypothesis stating that humans are at the root for the causation of global warming. His evidence was that humans are creating greenhouse gases such as CO2 and water vapor, which absorb heat, which in correlation, leads to the planet’s temperature rises. Another scientist named Guy Callender had emphasized the same point. Callender, an English inventor researched and found in his studies that “humans had added about 150 billion tons of CO2 into the atmosphere since the 1880’s (Weeks).” Since the year 1810, the CO2 levels have risen from 270 parts per million (ppm) to about 400ppm in 2010 (Eggleton). All these scientists share similarities, in that they are all on the search of whether global warming really does exist. However, these scientist share differences also. Those differences are that some scientists believe that humans have caused this issue, while others believe that this issue was caused by nature itself. The world has different perspectives on who is right and who is wrong, and with so many people using their own opinions, it makes it difficult to discover the truth, although, one point is correct and that being humans are at fault for the cause of global warming. Although global warming is seen as an incident caused by humans, some scientist may find it to be nature’s fault. William M. Gray a Professor of Atmospheric Science, states in his research that, “human kind has little or nothing to do with the recent temperature changes (Bily 58).” Gray’s supportive evidence is that the earth, every year, has its own temperature fluctuations...
