ENVIRONMENTAL SYSTEMS AND CLIMATE CHANGE1IntroductionThe climate of Earth has changed over the years and in the last 650,000 years, there have beenchanges in the glacial retreat and advance. It has been seen that there is a sudden end in the lastice age. This marked the beginning of a new era and in the initiation of the human era. The termanthropogenic means that greenhouse gases that are produced by the humans itself and throughtheir actions. The IPCC fourth report that was released in the year 2007 had the multiple lines ofevidence that confirmed that the post-industrial greenhouse gases did not arise from the naturalmechanisms. The most potent greenhouse gases are the nitrous, methane and carbon dioxide(Intergovernmental Panel on Climate Change, 2015). The study is based on finding whetherthere is an agreement within the scientific community regarding the anthropogenic climatechange.Anthropogenic Climate ChangeIn the coursework, I have come to know about the disturbances in the global carbon cycle anddue to the anthropogenic activities. There are certain aspects like the fate of the carbon dioxideemission caused due to the anthropogenic activities like the industrial emissions, deforestationand these have resulted into the storage of the global carbon into the sinks such as the oceans,forests and atmosphere (Team, 2018). The IPCC reports confirm that the past 8000 years, justafter the industrialization has resulted in the year 1750 has resulted into an increase in the rise inthe carbon dioxide which was a mere 20 parts per million. At that moment the concentration ofatmospheric carbon dioxide was 280 ppm and this level increased to 379 ppm in the year 2005.Thus, it can be said that there is a large increase of 100 ppm in about 250 years. Since the year1750, it has been estimated that the two-thirds of the carbon dioxide emission in the atmosphereis due to the burning of the fossil fuel and specifically due to the burning of the fossil fuel like

ENVIRONMENTAL SYSTEMS AND CLIMATE CHANGE2the petroleum and coal. About one-third of the pollution is caused by the land use changes likethe agriculture and deforestation (Woodward et al., 2014). 97 percent of the climate scientist has agreed that the cause of the global warming is thehumans itself. The level of the agreement is also considered as consensus, puts forward the factthat the humans are behind the cause of the anthropogenic global warming. Social scientist JohnCook and his colleagues at the University of Queensland through a research found that 97percent of the abstracts supported the idea of the climate change is man-made (Howard, 2013).One of the articles in Washington Post has mentioned that ideologically it is feasible to reject thefact that activities of human are actually contributing to the global change in climate. The issue,however, is that the huge number of the scientific evidence point towards a different direction.Even the majority of the computer models are inadequately configured thus are unable to providea clear picture. It is, however, important to note that the threat to biodiversity is used for thejustification of the policies and the evidence suggest that the threat exists and they are quite real.At the Scientific American, Michael Shermer said that a lot of scientists have providedalternative explanations to the available data and are provided with the various data that are notinconsistent and even contradict each other (Adler, 2015). From this reference I have learned thatthe majority of the environmental issues that arise are due to the ill effect of the variousanthropogenic activities of humans. I now feel confident regarding the fact that a lot of daily lifeoccurrences like the rise in temperature, change in the seasonal patterns, change in climate andthe rainfall are all due to the activities that contributed to making imbalances in the naturalprocesses and biogeochemical processes. The major effects of global climate can be seen throughthe lenses of the global rise in temperature and rise in the levels of the greenhouse gases that hascontributed positively to the temperature rise. Personally I feel that I have benefited from the
