Impact of oil exploration, extraction and transport 2 Essay

Impact of oil exploration, extraction and transport 2 - Essay Example Because of these, several legislations were enacted and promulgated, with worthwhile efforts being put up to control pollution and its related consequences. The responsibility of ensuring that these legislations and other recommendations were followed to the later became the mandate of the municipalities and oil exploration companies. After implementation of these structures, a remarkable reduction in the environmental problems that had earlier been common was experienced. The process of making decisions over perceived impacts of risks in the environmental situation involves coming up with various management decisions that rely on the proper assessment of probable risks that would arise from various environmental practices (Trefry 2003 150). In the U.S, the government has established a general structure to be used in making such decisions basing on the considerations for human health. These guidelines are useful in the process of determining the health and environmental impacts that certain economic activities can have on the people and the environmental in general. These guidelines have been used in various places with much success in the exploration industry for oil, gas and other petroleum products. Constant power supply is essential in the process of power generation; this is because, constant power supply facilitates the process of exploration. It facilitates the machines involved in the process thereby enhancing a smooth exploration and success in the process. The idea of installing a generator in the exploration site was informed by the need for having persistence in the exploration process and enhancing the safety of the people in the exercise. The chief engineer at the plant, John Akosa, ought to have established clear steps in the process of installing the generator so that there would not have been any loss of resource

Environment - Essay Example Though there is no one ultimate source of climate change, there are varying contributory factors that would lead to global warming. This paper would highlight the causes of climate change to get a better understanding on the human contribution to climate change and the problems that arise in assessing the human contributory factors. Climate Forcing Climate forcing are contributing factors that affect changes in the climate. Such forcing processes include solar radiation. Since our sun is our primary source of energy, scientists have looked at the relation of deglaciation and solar irradiance as the cause of the heating of the earth’s atmosphere. But they found out that solar irradiance alone is not responsible for the violent fluctuations in temperature but may act as trigger to initiate the trend (Rapp 2008). Another process that could influence prolonged changes in weather patterns are the orbital variations of the earth. Astronomers have discovered that there are changes in the earth’s orbit that in turn affects the distance between the sun and the earth. These changes in the orbital cycles in turn produces varying amount of solar energy that the earth receives. Elliptical orbit of the earth is associated with prolonged warm periods while ice ages are associated with circular orbits (Gabler et al 2009). Third is plate tectonic or the process of the vertical and horizontal movement of the earth’s crust. Because the earth’s surface has direct contact with the atmosphere and the oceans, its evolving character has direct correlation with the â€Å"incoming and outgoing radiation, atmospheric circulation, ocean currents and the location of elevated terrain suitable for glaciers and ice sheets† (Gornitz 2009, p.784). Another way that plate tectonic affects climate change through its process is because it has control over geochemical cycling and ocean and atmospheric composition (Gornitz 2009). Another contributing factor to clima te change is volcanic activity because volcanic eruptions release particle effusions and gasses that affect atmospheric composition i.e. volcanic ash and sulphur-rich gasses. Strong volcanic eruptions could substantially affect the carbon dioxide composition of the atmosphere. The 1991 Mt. Pinatubo eruption in the Philippines have helped in significantly cooling down the earth’s atmosphere for instance (Letcher 2009). Fifth, climate forcing is the ocean variability. Despite the very limited measurements and studies conducted with regards to understanding variability of ocean circulations and ocean processes, there are enough oceanographic evidence to suggest that the irregular distribution and flow of cold and warm sea water, combined with changes in the atmospheric pressures have long term effect in the redistribution of energy in the world’s oceans and even affects water salinity. This combined with transient climate events like El Nino could cause â€Å"regional le vel social disruption, economic loss, and environmental degradation around the world† (Kininmonth 2004, p.110). Thus, persistent anomalies would not allow for marine and other aquatic animals to fully adapt to the changes in ocean variability i.e. temperature, salinity, current flow (Kininmonth 2004). Problems in Assessing Human Contributory Factors Despite the many climate forcing variables that could contribute to climate change, it is the human influence over the environment that is the greatest force of all.
