Sample thesis and annaotated bibligraphy:Climatic change

Updated on March 6, 2015

Part 1- Essay and thesis statement

It is evident that the climate of planet earth is changing. This is because global temperatures have been gradually rising while being accompanied by other changes in weather. For instance, many countries have been experiencing abrupt changes in rainfall patterns. These changes have resulted to increased periods and occurrences of floods, frequent and severe heat waves that have consequently led to severe droughts (Knowlton, 2010). Additionally, climate change has been globally pronounced via different observations. For instance, ocean temperatures have been increasing and turning sea waters acidic. Similarly, the sea-levels have been dramatically rising while the ice caps at the peak of the highest mountains have been melting (Verner, 2012). These weather changes have also been accompanied by uncontrolled losses of ice in the seas, rapid changes in plant and animal biospheres and the shrinkage glaciers in the past ten years.

These changes in the global climate have posed both direct and indirect consequences on the health of human beings. For instance, increased heat waves have led to the rise of heat-related illnesses. The emergence of intense floods and prolonged periods of rainfall have resulted to increased water-borne diseases such as amebiasis, Campylobacteriosis and Cholera. It has also led to increased cases of Hepatitis A, Giardiasis, Viral Gastroenteritis, Vibrio infections, Cryptosporidiosis and many others. Similarly, rapid loss of ice, rise of sea temperatures and accelerated glaciation have resulted into increased exposure to many severe environmental toxins. The climate change has also led to increased intensity of cardiovascular diseases and conditions such as asthma and tuberculosis. Therefore, the current climate change is a threat to human populations because it negatively impacts their health.

[DNM1]This is a strong thesis statement. An excellent thesis statement contains an argument and a reason to support the argument.

Part two- Annotated Bibliography

Knowlton, K. (2010). Rising Tide of Illness: How Global Warming Could Increase the Threat of Waterborne Diseases. The Natural Resource Defense Council. Retrieved on 9th December 2014 from: web

In his writings, Knowlton highlights how the change in global climate affects the health of humanity. According to Knowlton (2010), global climatic change poses a threat to the survival and health of human beings by contributing to the outbreak of water-borne diseases. The author also argues that adverse climatic changes such as droughts are bound to negatively impact the lives of humans by encouraging droughts and famines (Knowlton, 2010). The droughts also lead to lack of food and clean drinking water. These result in the insufficiency of foods; hence leading to ill health and diet related illnesses such marasmus and kwashiorkor.

In my opinion, this article serves as a good source of reference in elaborating the thesis statement. Its content is unique and perfectly chosen because the points discussed by the author serve to vividly explain and elaborate how adverse climatic changes threaten people’s health by promoting the effects of waterborne diseases and their vectors.

Verschuuren, J. (2013). Research Handbook on Climate Change Adaptation Law: Research Handbooks in Environmental Law Series. Cheltenham: Edward Elgar Publishing.

In this book, Verschuuren explains how climatic changes affect human health by promoting the factors that facilitate the growth of harmful algae blooms and lead to both fish and food poisoning. In the light of this, climatic change forces sea temperatures to rise to abnormal temperatures. This creates favourable environments for the growth of harmful algae. At relatively higher temperatures, harmful algae blooms grow well and attract fish species. Being a typical food for fish and other marine animals, the fish consume the harmful and poisonous algae. Consequently, fishermen trap these poisoned fish while fishing and offer them to the markets for sale. Once people purchase and consume these fishes, they suffer from food poisoning (Verschuuren, 2013).

From a logical point of view, this article serves as a good source of reference while explaining how adverse climatic changes threatens people’s health. This is because the author of the article clearly explains how the effects of climatic change move from one tropical level to another until when they eventually get into human bodies and inflict ill health.

Verner, D. (2012). Adaptation to a Changing Climate in the Arab Countries: A Case for Adaptation Governance and Leadership in Building Climate Resilience. Washington, DC: World Bank Publications.

In this book, Verner wishes to further elaborate how climatic changes in terms of weather: humidity, temperature and wind, may negatively impact the health of mankind. According to Verner (2012), weather conditions such as wind, temperature, humidity affect the ambient air quality. This is because climatic changes amplify the ambient concentrations of ground-level ozone and aeroallergens (dust and pollen grains) which are the main causatives of respiratory diseases. The author also explains how severe climatic changes increase the levels of toxins in the environment, cause genetic mutations and lead to the birth of children with defects.

This article serves as a clear source of reference while debating on how adverse climate change negative affects people’s health. The strength of the article arises from the fact that the author uses the early stages of human development to explain how climate change may affect the health of an entire generation.

Reuell, P. (2012). Concerns about climate change, health: Harvard researchers warn of skin cancer danger in ozone loss. 30th July 2012 Harvard Gazette.

In this article, the author states that climatic changes cause skin cancer. According to Reuell (2012), increased rates of global warming accelerate the hydrological cycle. Consequently, high amounts of water vapour are injected into earth’s stratosphere and cause thunderstorms. These thunderstorms react with the water vapour, convert stable forms of chlorine and bromine into their radicals (Reuell, 2012). Chlorine and Bromine radicals then convert ozone molecules into oxygen molecules, thus depleting the Ozone layer. Once the Ozone layer is depleted, ultraviolet radiations from the sun pass into the earth’s atmosphere induce mutations into people’s skin cells. The later results to cases of skin cancers.

In my opinion, Ruelle’s article serves as a good point of reference in explaining how adverse climatic change and global warming affect human health. This is because the article does not only rely on the basic knowledge that people have concerning skin cancers. The author goes to the extent of pointing out, explaining and simplifying the hidden processes or mechanisms undertaken for climatic changes to induce skin cancers.

The US Environmental protection Agency. (2013). Climate Impacts on Global Issues. Retrieved on 9th December 2014 from: source

In this Article, the staff at the Environmental Protection Agency (EPA) of the US summarises all the possible ways via which adverse global climatic changes might negatively influence human health. The impacts are grouped into four main categories: climatic impacts related to the basic human needs such as; food, shelter, health and water and vulnerable human populations such as the minorities (The US Environmental Protection Agency, 2013). They are also categorised based on their impacts on air quality and the national security.

From a logical point of view, the EPA’s article is an important source of building the essay on how climatic changes negatively impacts the health of human beings. The core strengths of the article are founded on the fact that the article focuses on explaining how climatic changes affect the health of human populations via their food supplies. Aspects food and health are closely tied because health depends on the food that people consume. Reducing the supply of food is definitely bound to affect people’s ability to fight diseases and later lead to ill health.
