Another imperative statistic from scientists is the verity that there is an over 40% increase in the rates of carbon dioxide and alarmingly, half of this has occurred after the 1970’s (Braasch, 2013). 98% of scientists collectively agree that 98% of the climatic change (with much emphasis on global warming) is caused by human activities (Gleb, 2013).Some people have argued that climatic change should not be ascribed to human activities. The opponents argue that there isn’t any scientific knowledge or physical evidence that has been provided to prove to the fact that human activities have caused the global warming (Madona, 2013). They further argue that climate change is a natural and innate process, that even if the industrial revolution had not taken place, the changes being experienced would still have been witnessed (Shipley, 2011). In addition, they dispute and say that the computer models used to generate the data to support the fact that climate change is man-made are usually wrong and that people should not base their conclusions on this data (Shipley, 2011; Madona, 2013; Braasch, 2013). Lastly, they dispel this idea by saying that an increase in temperatures would probably make the earth more habitable and suitable for plants, the human race and for animals (OSS, 2012).However, it is important to be realistic and realize that climate change is man-made. If the industrial revolution had not taken place, would the Carbon Dioxide levels be as high as it is today? Burning of fossil fuels by human beings has led to a massive increase in the rate of carbon dioxide emitted to the atmosphere. Research shows that only 450 gigatonnes of carbon dioxide are absorbed by plants, whereas the oceans absorb about 439 gigatonnes of the total carbon dioxide emitted and released per year. This is a smaller volume compared to an excess of these that is produced from the industries and many other human activities. The excess of the carbon dioxide remains in the atmosphere for a very long time, and this affects the climate of the earth.
