Thesis Statement Global Warming is an extremely important topic to study because global warming is one of the most threatening environmental problems and may be one of the greatest challenges facing humanity. This essay will be focusing on how the Arctic region is greatly affected by global warming. II. Introduction Since the late 1800’s the surface temperatures have increased about .6 degrees Celsius and in the last 25 years surface temperatures have increased about .4 Celsius (NCDC Website). The Intergovernmental Panel on Climate Change (IPCC) says that the global warming that we see today is unlikely to be of natural variability alone (Cunningham, 2006). Scientists have stated that human activities are contributing to global warming by adding large amounts of heat-trapping gases to the atmosphere (UCS Website). This topic is important because global warming emissions remain in the atmosphere for many years (UCS Website). Emissions of carbon dioxide and other heat-trapping gases that are emitted primarily by the burning of fossil fuels and the clearing of forests cause global warming (UCS Website). For this reason, the decisions that are made today will affect both the climate and the air quality of future generations.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
