Global Warming: Dengue Introduction: The recent decades have witnessed an outbreak of a range of infectious diseases in various parts of the globe. Examples include: the Haiti Cholera outbreak in 2010 following the earthquake in January in the same year; Salmonella Enteritidis on account of contaminated Salmonella and eggs in the United States in August 2010; Multistate E…

Approximately 50 million people worldwide were affected by the Dengue fever leading to 19,000 deaths in the year 2002 according to statistics made available by W.H.O. Experts, researchers and scientists have attributed this phenomenon to global warming claiming that it has led to a substantial rise in the amount of water including sea water as well as fresh water bodies - which are predominantly considered as breeding grounds for mosquitoes. Furthermore, some scientists also believe that the sudden change in temperatures and shift in seasons could also be attributable to the rise in incidences of such outbreak of vector-borne diseases such as dengue and malaria (msnbc, 2007). Various factors are and could be held accountable for such an occurrence. This includes the sudden increase in urban population, increased incidence of international tourism, as well as exchange of goods and products across several countries, as a result of globalization. (NRDC, 2011). Impact of global environmental changes on outbreak of infectious diseases: The natural environment plays a key role in the globalization phenomenon, as it leads to an increased exchange of goods and services, as well as travelling between various geographic locations across the world. Furthermore natural phenomena such as earthquakes, tsunamis, hurricanes or accidents such as oil spills etc lead to depletion of natural resources causing severe imbalance, and leading to various air and water borne diseases. According to studies conducted over the years it was estimated that global warming is likely to cause increase in sea levels, leading to disruption of the eco-systems; cause further expansion of deserts and lead to increased storms and violent weather. Furthermore all the disruptions in the ecological system leads to a further disruption of the business activities such as transport of plants and animals. For instance, there is a shift of various species of birds and animals to different locations and a simultaneous change in the food chain, resulting in a destruction of various species. Diseases are increasingly going global. For instance the migration of the A2 strain of potato virus from central Mexico to the potato fields in the U.S.; leading to a large scale devastation of crops and translating into millions of dollars worth of losses (Winslow, 1995 in Clegg et al., 1996). Global warming poses a significant threat with regard to the spread of various infectious diseases because of its various repercussions such as increase in temperatures, leading to increased humidity in tropical and sub-tropical areas which are a prime breeding ground for mosquitoes, which in turn are the primary sources of water-borne diseases such as dengue fever and malaria. Figure: Climate change and the dengue fever vector Source: Christophers (1960, Pp. 49) As mentioned in the previous section of this paper, global mobility has further increased the chances of outbreak of infectious diseases worldwide. For instance, the Asian tiger mosquitoes are now biting the Americans, while termites from Taiwan are destroying American homes. According to Coates (2006) the breeding of this breed of temperate zone mosquito in the U.S. was first recorded in the year 1984 in Houston, Texas which spread to other parts of the

While these developments have made life on earth so easy for humans, they entail several disadvantages especially in the context of their negative impacts on the environment. One among such problems, which remains a major worldwide concern, is the issue of global warming.
The fluctuations in the global temperatures occur naturally. However, has been it is realized that the average global temperatures are increasing at a higher rate. Simpson (2008) notes that for 10 years since 1990, the hottest years to be recorded occurred.
The effects on the environment lay a great impact on the living of the people and human activities have greatly altered the environment of the earth. Global warming is one of the most important environmental problems that mankind is facing. According to Sir David King, the chief scientific adviser of UK Government, “Climate change is a far greater threat to the world than international terrorism.” (BBC, 2004).
This event is known as global warming, the gradual increase in the overall temperature of the earth’s atmosphere. Global warming is one of the greatest threats that our world is currently facing, putting at risk not only the state of our planet, but our lives as well.
Although relevant in planning for catastrophic situations, the results of this type of research may be too far in the distant future for the public to be appropriately concerned. In this paper, I will address research regarding global warming and the rise of dengue fever based on current trends and medical crises in the Americas.
Global Warming will assist the spread of dengue fever into new territories.
Dengue fever is an infectious disease that is spread by mosquitoes. There is the risk of deadly complications in the form of dengue hemorrhagic fever and dengue shock syndrome
Harold Lewis, an Emeritus Professor of Physics let the cat out of the bag because his conscience and his moral values couldn’t take any more of this lie. He wrote his intense and full of regrets letter of resignation with
According to scientist, this rise of surface temperature is primarily due to increase in concentration of greenhouse gases like carbon dioxide emissions. Moreover, these emissions are as a result of human activities, such as;
However, at night tend to go back to the space, green house gases trap the solar radiation at night by blanketing the solar radiations. Solar radiations are reradiated by the green house gases that help in maintaining the temperature of the earth. In this way, green house
