Global Warming:Fact or Fiction
Global warming is an observed trend of rising temperatures in the atmosphere and on Earth since the 1900s. The degree that it has risen seems to be in questioned because I have found many conflicting answers from .5 to .6 degrees C, the amount of time is also multi-answered. The theory of global warming being caused by man is that a humans got industrialized, the burning of fossil fuels is wreaking havoc on our atmosphere. As or atmosphere thins, we are then more vulnerable to the sun’s harmful rays. Some forecast mass extinction for most of living organisms as the worst case scenario.
Green house gases are blamed for the gradual rise in temperature. These gases include; carbon dioxide, methane, chlorofluorocarbons, nitrous oxide and water vapors. Many causes of these green house gases are the burning of fossil fuels and deforestations. With large amounts of CO2 being released and less vegetation to absorb them, this is thought to be the cause of global warming. Industries like oil refineries and power sources burn loads of fossil fuel and may be saw as the primary producers of greenhouse gases, however farming, namely cows emit considerable amounts of methane. China is the largest producer of greenhouse gases producing over 7 million thousands of metric tones, America not far behind with over 5.4 million.(Ransom, 2012)
There is evidence that the world is changing, gradually becoming hotter. However there is no concrete evidence to be found on its causes being linked to humans. Many scientist believe that the world’s climate goes in stages over millions of years, as with mass extinction of the species on it. “Increasing in concentration (CO2 emissions) for over a century with no proof of any warming yet”(Armstrong and Kesten, 2012). Proof that there isn’t global warming can be argued with the above reasons and some even think that global warming “is simple the latest example of a common social phenomenon: an alarm based on unscientific forecasts of a calamity” (Armstrong and Kesten, 2012).
I personally believe that humans are affecting the planet, whether it be global warming or the extinctions of many species. I think that the information is so skewed and so many different findings, it is hard to believe or know which report is accurate. I must also say it hard to believe that we are not having negative effects on the Earth with a consumption lifestyle, however I do not know if forecast described are anywhere close to what will happen, there is too many changing variable to look that far ahead. If change is going to happen to treat the environment better, it will come from education, awareness and government policies imposed on company leaders, as well as consumers.
