This paper evaluates either side of the arguments.
There has been an increasing evidence that greenhouse gases resulting from man-made activities have caused climate change, specifically global warming. As noted by Pittock, both proponents and opponents of man-made causes of climate change appreciate the warming effect of greenhouse gases (68). These gases include methane, nitrous oxide and carbon dioxide. Carnegie Mellon University further observes that greenhouse gases in the atmosphere have increased by between 10% and 30% from the start of the industrial revolution. These gases allow the sunlight into the Earth’s atmosphere and then trap a significant portion of this radiation, preventing the reflection of sun’s radiation back into space. This leads to a warming effect in the Earth thus the contribution of human activities to global warming.
Secondly, scientists have been able to identify carbon-dioxide from human activities as the largest contributor to greenhouse gases in the atmosphere, thus attributing global warming to human activities. According to these scientists, the pre-industrialization period had the atmosphere contain only 280 parts per million of carbon dioxide. By 2010, this had increased to 390 parts per million. This additional 100 parts per million of carbon dioxide is what is attributed to human activities (Poortinga et al. 1017). To show that this extra carbon dioxide is from human activities, scientists use the fingerprinting technique. From this, it has been noted that natural carbon dioxide has some low portion of carbon-14. The lack of this carbon-14 isotope in the additional 100 parts per million of carbon dioxide attributes its source to human activities as opposed to natural factors.
Finally, the proponents of man-made climate change give evidence against natural causes. This school of thought argues that if the current climate was following the natural trend, then,

Global warming is a phenomenon which basically manifests as an increase in the earth’s temperature. With a warmer temperature base, the earth also undergoes various changes including the melting of its polar ice caps and the shifts in its weather patterns.
It is a fact that the average atmospheric temperature has increased more than 1 degree Fahrenheit since 1900. Moreover, climate changes, unexpected floods, storms, earthquakes, tsunami, etc are taking place quite frequently in recent times. Sea level is also rising because of the melting of huge ice blocs in the Polar Regions.
Name Instructor Class Date Global Climate Change Although the subject was not part of the recent presidential debates, global climate change is the most important issue facing the U.S. and the world. Also refereed to as “global warming” the phenomenon is already taking its toll on the planet.
(The greenhouse gases of the majority concern are Carbon Dioxide (CO2), Methane (CH4), with nitrous oxides.) The recent consequence that climate modify has had is the equal of a 1 watt light bulb burning over each square meter of the earth (Brown BE, 163-170).
Life, as we know it on earth today, is being threatened by the phenomenon of Global Warming. The term denotes “the recent reported increase in the mean surface temperature of the earth; the increase being attributed to increased human activity and in particular to the increased concentration of greenhouse gases in the atmosphere”
These warm periods, called interglacial periods, appear to last approximately 15,000 to 20,000 years before regressing back to a cold ice age climate. At year 18,000 and counting our current interglacial vacation from the Ice Age is
The media has contributed in propagating this notion today through advertising and various television programs. For many years, Behavioral Psychology has taught that primate behavior just entails patterns of
The biggest contribution to the climate change arises from burning of the fossils releasing carbon IV oxide gas to the atmosphere (NAS 18). The burning of fossil fuels is not a natural phenomenon; it is a process
