QUESTION

You have nearly completed an entire course surveying the Earth sciences. You have learned an immense amount about the various components of the Earth system and have applied that knowledge in a variety of lab, quiz, and writing assignments. Recently, the U.S. National Climate Assessment and Development Advisory Committee (NCA) released a report stating that the United States is already being impacted by global climate change. To review highlights from that report (by region) or download the full report, click here:

NCA Report on Climate Change ( http://nca2014.globalchange.gov/ )



For this final reflective essay, I would like you to write a 5 to 6 paragraph essay answering the following questions:

* Is climate change real?
* Is climate change human-induced?

Draw on your knowledge of the Earth sciences when answering these questions. Provide a substantive argument that utilizes data and information you have learned in this course to support your argument. Provide citations for these data within the body of the essay.

This is the final essay of the course, and I expect it to be a substantive one. Each paragraph should average 4 to 5 full sentences. I’m looking for a complete, well thought out essay here. Be thorough and descriptive in your essay and be sure to draw on the materials covered in the course directly. For full points, you should not simply write an opinion piece – you must back up your opinions with facts derived from the report and your readings and assignments.

Climate Change Reflective essay

            Climate change has been a contentious matter in modern earth science. Many people often fail to prove that his phenomenon is real. This process takes place gradually, and it may be difficult for people to assess such changes that may take place in decades. However, changes in climatic systems and other earth conditions are accurate proofs that climate change is real. Various reports such as the NCA Report on climate change are appropriate sources of information regarding climate change (National Climate Assessment 1). Such a report presents changes in global systems based on temperatures, sea levels, ocean acidity levels, and melting of ice.

            One proof of the existence of climate change is the temperature trends experienced in parts of the world such as the United States. As such, U.S. temperature trends in recent years have witnessed a substantial increase by 1.3°F to 1.9°F annually, according to records taken since 1895 (National Climate Assessment 1). Conversely, this increase was not maintained at a constant over years. These temperatures rose gradually until 1940 when a momentary decline occurred before a rapid increase after 1970. In my opinion, these facts are a true indication that climate change is a real phenomenon.

            The other proof that climate change is real is observing the sea levels. These are some of the concrete indications that the group is undergoing a substantial change. The initial reliable records on sea level were taken in 1880. Ever since, records indicate that the sea level has risen by approximately 8 inches. Scientists forecast a further increase in the level in 2100 by 1 to 4 feet (National Climate Assessment 1). These changes are not a mystery but an indication that global systems are undergoing considerable changes.

            Ever since industrialization, there have been increased human activities. I believe that these activities have handled the aggravation of climate change. Various evidence presented by research on global systems depict the input of human activities in causing climate change. Emissions from various human activities have led to an increase in the atmospheric heat. Consequently, the oceans absorb approximately 90% of this heat (National Climate Assessment 1). Ocean waters expand as they warm up, which leads to an elevation of their levels.

            Carbon dioxide emissions from factories find their way into the oceans when they are absorbed by rain. Thus, oceans absorb nearly a quarter of the total carbon dioxide released into the atmosphere yearly (Kusky 33). Consequently, the acidity levels in oceans increase considerably, which alters the marine ecosystems. In my opinion, the acidity of oceans is an indication of the influence of human activities in causing climate change. If the levels of carbon dioxide were normal, the acidity levels would be maintained at the required levels.

            Human activities have led to an increase in levels of greenhouse gases emitted into the atmosphere. The net effects of the increased levels include increased ocean and air temperatures, a rise in sea level, and vast melting of snow (Kusky 33). The increase in the levels of gases was caused by human activities such as agriculture, land-use change, and fossil fuel use. The concentrations of greenhouse gases in the atmosphere have increased to 400 parts per million from the 280 ppm recorded towards the end of the 18th century. The trend of increasing world surface temperatures has been predominant in the late 19th century. These facts are evidence of the effect of human activities in causing climate change.
