Human Impacts on Climate Essay Example for Free

Human Impacts on Climate EssayAl venires documentary An Inconvenient Truth is non only informative precisely an eye opener especially for those living in the United States. Today global warming is not an obscure phenomenon but a reality that is being faced by everyone from Africa to Australia. Mankinds actions are now more than ever before are changing the mood of Earth. These actions lead to effects which combine with the natural occurrences which have been taking place in history.In addition evidence from scientific research shows that natural contacts but cannot be blamed for the increase in the global surface temperatures recorded in the past century. Mans effect on Earths climate has several consequences like Escalating concentration of green house gases in the atmosphere Air pollution Concentration of airborne particles Changes in land geology The major problem is the increase of carbon dioxide in the atmosphere cannot be compared historically as the levels today are much higher then ever before, the elision being when earth was hit by a meteorite etc.the changes and the increase in carbon dioxide have been witnessed since the modernization and industrialization which began in the 1700s except the worst impact has been since fossil fuels were used excessively from the beginning of 1900 and this also led to change in the use of land. (American Geophysical Union) Al Gore, through statistics shows that thither is a direct relationship between the rising concentration of carbon dioxide in the air and the increase in climatic temperatures.Historically the first impact of the human presence on Earths geographical and biological systems occurred about 8,000 years ago, when individuals began to systematically cultivate land for agricultural purposes. However the initial impact was not as severe or drastic as the one which occurred in the 1700s. The industrial revolution has been supported and encouraged by the set which have led to glorifying co nsumption and economic development. (American Geophysical Union)It is a fact that this planet is heating up because of the human society and the greenhouse gases produced. correspond to the both The National Academy of Sciences and the United Nation have come to the conclusion that there is a relationship between human actions and the temperature increases. (Clark 1013) According a conjugation statement by G8 in addition to China, India and Brazil, that stated that scientific evidence was quite remarkable and there was no way for the nations but to take actions to substantiation this destruction. (Clark 1013)The reality is that if people keep on emitting greenhouse gases at this rate, atmospheric temperatures will keep on increasing, and the effect will be felt for generations in future. According to even strict actions like Kyoto Protocol may be able to control the increasing carbon dioxide after a centaury at the minimum. According to Clark (1013) Research on ice cores by Fedor ov et al. (2005) detailing the relationship between carbon dioxide and temperature going back more then 400, 000 years has displayed that there is a strong correlation between carbon dioxide and temperatures.Studies show that historically there was never a time when there was so much carbon dioxide as now in addition the increase in carbon dioxide concentration has increased most rapidly in the past hundred years or so. (Clark 1014) In a news brood on National Geographic in February, The Intergovernmental Panel on Climate Change (IPCC) very assertively link up the mans actions being responsible for the global warming and other climatic changes like increase in sea levels, storms and changing weather patterns.The report quotes Achim Steiner, executive director of the United Nations Environment Program, comment that Fossil fuel use, agriculture, and land-use change are fundamentally affecting the systems on our planet (Roach) What Al Gore has done is just point out the facts in a si mple style through his documentary so that general s can watch what is happening and do something about this very significant problem.Works CitedHuman Impacts on Climate.
