Essay on Anthropogenic Global Warming

The issues surrounding Global Warming or Anthropogenic Warming introduce several different hypotheses. One is the Anthropogenic Global Warming (AGW) hypotheses which has become the most looked at theory. It supports the claim that climate change is due largely in part because of human activities. It also claims that human activity will eventually bring the world to an end. While the AGW is being argued there is also the issue of what is called the Kyoto Protocol which many scientists have urged the U.S. government “not to sign”, saying that the increase in Greenhouse Gases is a result of increased atmospheric carbon dioxide caused environmentally. These scientists have signed a petition to stop the Kyoto Protocol on the basis that there …show more content…
The real issue is how fast it is warming up and this creates debate on “what” is causing it to do so (Global Greenhouse 2011). One of the greatest arguments about global warming is the history of the Medieval Warm Period (roughly 800 to 1200 AD), which show that the earth had warmed to a greater extent than we have seen so far. This was a period in which settlement had just begun and large industries had not even been brought into focus yet. According to the IPCC (Intergovernmental Panel on Climate Change) the increase of post-industrial use in greenhouse gas is not a condition of natural mechanism; therefore they are stating that the increase in greenhouse gas is created from human activities (Global Greenhouse 2011). The most potent of these gases are carbon dioxide (CO2), methane (CH4), and nitrous oxide (N20). The IPCC claims that 2/3 of this change comes from fossil fuels such as coal and petroleum based products and only 1/3 coming from land use such as deforestation and agricultural (Global Greenhouse 2011). Currently our experts rely on the use of satellites and land-based temperature stations which creates the argument that one gives false readings over the other. The satellites are in fact more reliable than the land-based equipment. The land-based equipment often is contaminated by heat generated by nearby sources such as cities consequently; the data from these is based on
