Introduction:

            Global warming may be defined as the increase of the earth’s temperature at an average rate that causes change in the climate conditions. Such changes include: change in rainfall patterns, effects on wildlife, humans and plants, rise in the sea level among other things.  Global warming occurs as a result of the “Greenhouse effect”.  This is whereby the earth absorbs heat from the sun and this heat is then radiated back into the space.  The heat is then trapped back by the green house gases that are available in the atmosphere.  Global warming was first experienced in 1989 and since then, various debates concerning the issue have been sparked by economists, environmentalist, scientists and also industrialists (Schneider, 1990, 286).

            In the last century, global warming has been increasing at 1oF (0.6oC) which is the average temperature of the earth and summers have been experienced to be getting hotter while winters milder.  This warming effect is not far from stopping as it is anticipated to produce other greater and worse effects including drastic changes (Alvin, Virginia & Laura, 2003, 6).  Half of the greenhouse warming has been as a result of carbon dioxide which is caused by fossils fuels that are burnt by man.  Other gases include: methane, tropospheric ozone, CFCs and nitrous oxide which are also responsible for the warming in greenhouses.  The increases in the amount of these gases have been linked to the ever growing human population and industrialization and this has also resulted in the 80% carbon dioxide.

            Human activities and climatic changes have both resulted in global warming.  Activities such as felling trees, combustion of fossil fuels for the generation of energy result in the emission of carbon dioxide that eventually have a negative impact in greenhouse gases whereby there is a decline in the ozone layer and increased acidity in the ocean waters hence endangering human animals and plants (Mathiesen, 2004, 126).

            Population increase has resulted in deforestation because human beings continue to burn fossil fuels in order to generate energy for use.  It is estimated that today, approximately 5500 acres of rainforest are cut down daily and 50 million annually. The levels of global carbon dioxide have in the past years risen to 0.4% annually.

            Another cause of global warming is technology although it is a partial cause. As a result of advances in technology, population has been on the increase hence the limited resources cannot be able to sustain it. Technology results in industrialization. The oil and gas fuels produced as a result of industrialization are used by man hence increasing the flow of carbon dioxide.  The modern technologies which man is constantly using have been proved to be more destructive to the earth’s resources (www.geocities.com/Timesquare/848/global.html).

            Global Warming commonly known as the “Green effect” has resulted into various effects that range from those of the environment, health of human beings as well as economic effects.  Human health has been affected by the current global warming in several ways. Since global warming is mainly concerned with the rise in temperature, this has resulted into quite a number of vital diseases such as Malaria and the west rule virus.  This could also be very dangerous to poorer countries because they do not have enough facilities and resources to compact this epidemic. Moreover the rises in temperature as a result of global warming will have an impact on human population.  Mortality rate is bound to increase.  For instance people who have cardiovascular problems are affected by high temperature.  People have also been known to have died of heatstroke in the recent past.  Others have experienced exhaustion problems (www.buzzle.com/articles/effort-as-effects-consequences-global-warming.htm.).

            High temperatures have the impact of concentrating the ozone layer in the lower atmosphere region, causes respiratory problems,  cause complications in the lung tissue hence complicating the health status of individuals with asthma.  Global warming has also endangered the lives of many through natural disasters such as hurricanes such as those that were experienced in the Caribbean’s and Florida. This disaster left a lot of people were homeless as a result of floods (Houghton, 2004, 123).  It is therefore evident that global warming poses human threats especially those living along the coastal areas.

            Another threat that global warming poses is the decline in agriculture as a result of the role that carbon dioxide plays in photosynthesis.  Agricultural productivity falls because carbon dioxide prohibits photorespiration hence damaging a lot of crops.  Agricultural output is also bound to be affected as a result of long spells of drought caused by global warming.  Droughts on the other hand increase the amount of the ozone gas will leads to the depletion of crops. These also lead to mass loss of lives in the affected regions. Even before ultimate death the communities in these regions undergo very severe sufferings.

            Global warming also affects the current infrastructure in the world.  Roads, ships and bridges constantly experience variations in the temperature level which leads to damages. The cost of maintaining these facilities are constantly increasing hence a burden to the economy of a nation.  As a result the runways break, foundations sink and the roads become malformed. Such funds could be used to develop other areas other than to repair the damages caused by the global warming.

            Rise in the sea levels has also been caused by global warming hence raising the cost of the coastal defense.  Global warming posses the threat of destroying the existing buildings and roads that border the sea through floods, storms and hurricanes.  A report was published in 1992 by the United Nations which proposed that if the current rate of the emissions of carbon dioxide and other gases continue, the coastal plains of both the Netherlands and Bangladesh will flood by the time the world reaches the year 2100.  Moreover, the Islands in Maldives will become extinct and this will happen at an only two foot of the increase in the sea level.  Trade in these coastal areas will also be adversely affected as a result of floods (www.buzzle.com/articles/effects-consequences-global-warming.html).

            The daily level is also affected by the global warming.  Extreme temperatures increase the level of evaporation.  The ecosystem is also affected by global warming as already seen by the behavior of birds. As a result of the change in the ecosystem many traditional inhabitants will be forced to move out of their normal places/residence to look for new ones.  The productivity in these ecosystems is also bound to decrease and as a result of global warming.  The warming of glaciers is also likely to produce floods (www.buzzle.com/articles/effects-consequences-global-warming.html)

            However, global warming has also been viewed to be having various positive impacts globally.  First, some economists view this as a business whereby they argue out that warmer climate could result into some benefits to human beings as well as certain crops.  Secondly other scientists believe global warming posses no threats as the earth is simply cooling off. They argue out that the phenomenon of global warming is not fully understood hence no one really knows whether the sudden change in the earth’s climate is a natural phenomenon.  (www.geocities.com/Timessquare/1848/global.html)/

            Global warming has adverse effects on the nations of the world and the planet.  This therefore calls for measures that could help in reducing global warming.  There are several ways that could be applied to help reduce the current rises in temperatures in the world.

Reduction in the demand for electricity by human beings is one way of reducing global warming because if reduces the amount of power that people use, saves money and leads to the availability of clean air since fossil fuels are burnt at a lower rate.

Air pollution could be reduced by using cars that demand less fuel, planting trees that hence increasing the process by which this trees capture and store carbon monoxide, recycling of trash and countries introducing laws that could be helpful in sustaining the global environment. In addition, the use of bicycles as a means of transport rather than for leisure, etc, reduces urban air pollution and greenhouse gases.

Paper components that require recycling could be reduced through the elimination of large scale advertising hence reducing the continuous massive depletion of forest resources. However termination of certain activities in ecological conservation is not equitable to throwing people out of work. This act is a capitalistic phenomenon. Conservation involves redefinition of tasks forming part of the plan under which the processes are needed to be carried out. The shift away from energy intensive and capital-intensive technologies creates more room for manpower.

Global warming can also be fought by use of traditional methods. For instance, use of bio fuels, which can be afforded, sources of renewable energy, and ensuring efficient utilization of energy. Thus, the military especially in the US where most fossil fuels are used should minimize its use of oil. The economic sector should also see to it that it is energy efficient and that it does not release excess gases, which is not needed.

In conclusion, it is evident from the discussion above that global warming has affected our planet adversely and will continue to do so. Rising temperatures and varying climatic changes are being experienced in various regions. Global warming should therefore be considered as a global disaster whose effects and consequences cannot be handled. Appropriate measures to curb global warming should be put in place as early as now to stop it before it is too late. It should be realized that this is not an issue for some regions alone but that global warming will affect the whole globe eventually. All countries must therefore play their role.

Non-governmental organizations that play a major role in influencing the decisions reached in meetings across the globe should see to it that they do not compromise their powers to influence the decisions reached at in such global meetings.  Non-governmental organizations are independent and free from influence from any powers.
