‘The Implications For Health In Global Warming’ This essay will discuss global warming and the degree to which it will negatively affect people’s health and well being. Negative global warming related health effects will vary greatly due to geographical location and socio-economic status. Generally developed countries will be far better placed to confront the health challenges of climate change, than the developing word that already experiences a lower average state of health and less developed infrastructure. Global warming refers to the measurable increase of average global air temperatures over the century (1905 to 2005). The 2001 United Nations Intergovernmental Panel on Climate Change (I.P.C.C) concluded that since the mid…show more content…
El Nino is the most powerful agent for short term climate variability in the world. The 1997-98 El Nino event is considered responsible for creating extreme dry conditions leading to forest fires in some parts of the world, along with extensive flooding in others. Climactic change brought about by El Nino has been linked to drought and the spread of diseases such as malaria in Latin America and South East Asia and to a lesser extent, cholera, hantavirus infection and Rift Valley fever. Torrential rain in much of East Africa associated with the 1997-98 El Nino event, caused a malaria epidemic in the highlands of south western Uganda. During the same period, hospital admissions for children suffering diarrhoea in Lima Peru, was two fold higher than that of the preceding four years. The increase in temperature in excess of normal seasonal variations was found to be the main environmental variable impacting upon admissions. The degree to which the frequency and severity of El Nino events are affected by global warming is currently being debated, with many climatologists suggesting a link with global warming. (Patz & Khaliq, 2002, Patz, 2004) Weather plays a key role in the dispersal of air-born pollutants. Periods of high levels of air pollution, ‘air pollution events’ are often associated with slow moving high pressure or anti-cyclonic systems. These systems hamper the normal pollutant dispersal process, leading to higher concentrations of air born pollutants at
