Global Warming and the Greenhouse Effect Essays - 793 Words

What is the greenhouse effect? It is the behavior of solar radiation when it interacts with gasses in the Earths atmosphere. The Sun gives off a wide spectrum of energy which we classify according to its wavelength. Among the types of energy given off by the sun are ultraviolet (UV), visible and infrared (IR) wavelengths. UV is short wavelength high-energy radiation, visible is mid-wavelength, mid-energy radiation, and IR is long wavelength low-energy radiation. The atmosphere is mostly transparent to UV and visible light, but some components of the atmosphere absorb IR energy on its way in toward the Earths surface, warming the atmopsphere slightly. When the suns energy reaches the surface†¦show more content†¦A balance between energy coming in from the sun in the form of visible radiation (sunlight) and energy constantly being emitted from the surface of the earth to space determines the temperature of the earth. The energy coming in from the sun can pass through the atmos phere almost unchanged and warm the earth, but the infrared radiation emanating from the earths surface is partly absorbed by some gases in the atmosphere and some of it is re-emitted downwards. This further warms the surface of the earth and the lower atmosphere. The gases that do this naturally are mainly water vapour and carbon dioxide. An analogy is made with the effect of a greenhouse, which allows sunshine to penetrate the glass that in turn keeps the heat in, hence the greenhouse effect. Without this natural greenhouse effect, the earth would be over 30 °C cooler and would be too cold to be habitable. But as greenhouse gas concentrations rise well above their natural levels, the additional warming that will take place could threaten the future sustainability of the planet. The extent to which changes in temperature over the last 100 years are due to human activities has been studied by looking at patterns of change across the surface of the earth, and vertically through the depth of the atmosphere and the ocean.

The greenhouse effect is a natural process that keeps the earth at temperatures that are livable. Energy from the sun warms the earth when its heat rays are absorbed by greenhouse gasses and become trapped in the atmosphere. Some of the most common greenhouse gasses are water vapor, carbon dioxide, and methane. If there were no greenhouse gasses, very few rays would be absorbed and the earthRead MoreGlobal Warming and the Greenhouse Effect1974 Words   |  8 PagesThe Greenhouse Effect and Global Warming Recently, global warming has moved to a serious scientific issue.

The greenhouse effect is a naturally occurring process that aids in heating the Earths surface and atmosphere. It results from the fact that certain atmospheric gases, such as carbon dioxide, water vapor, and methane, are able to change the energy balance of the planet by being able to absorb longwave radiation from the Earths surface.

Development of Self as a Nurse and Practice

Question: Discuss about the Development of Self as a Nurse and Practice. Answer: Introduction In order to maintain the quality of the nursing practices, the nurses of different healthcare institutions need to follow the code of ethics. The code of nursing ethics seems to importance for indicating the nurses about necessary decisions and actions with which they can handle a critical situation (Zahedi et al. 2013). These ethics indicates the nurses to handle their every patient equally and properly, regardless to the gender, class and type of the diseases. In this assignment, the ethical duties of the nurses have been described, depending upon the case study of Mr. Jones that helps to understand the self-development of a patient. Analysis From the case study of Mr. Jones, I have been observed that the patient is a patient of unmanaged diabetes and also has a tendency of alcoholism which has increased after the death of his wife after a long conjugal life. It affects him psychology in such a way that he again starts taking alcohol and ultimately is taken to the hospital with acute abdominal pain with vomiting tendency. The medication procedure of Mr. Jones is basically dependent upon pain relieving medicines, especially Morphine with a limited dose. The assigned nurse of Mr. Jones tries to give relieve to her patient by increasing the dose of Morphine after treating him in other occasions. In order to increase the dose, the nurse indulges in verbal argument with the physician who is concerned with the side effects of the dose of Morphine on the body of Mr. Jones as he is an aged man of fifty nine. According to me, the nurse was trying to decrease the level of pain of her patient, as per the ethics of nurses for which she approached the physician to increase the dose. Ethically there is no fault in the behaviour of the nurse, because she fights for the providing advanced care to her patient, which tends to create an authentic bond between the patient and the nurse. According to Douglas et al. (2014), the four major steps of caring in the nursing profession includes showing concern about care, taking care about something, giving proper care and receive the care. On the contrary, from the viewpoint of Kangasniemi, Pakkanen and Korhonen (2015), the four important care providing measures includes sense of responsibility, attentiveness towards the needs of the patient, sense of competency and the responses of the care receiver. The nurse in this case, fulfills these four factors by being responsible and attentive towards the need of Mr. Jones who feels massive abdominal pain. I thin k, this nurse do have the sense of competence towards the professional responsibility as a nurse which I also need to possess if I want to improve my career as a nurse. Like the nurse, I also need to be attentive towards the needs of my assigned patient along with doing the required actions in order to provide the patient physical relief. The conflicts between the professional nurses with the physicians are very common in the healthcare sector. However, if the nurse tries to implement her own idea and understanding in the medication procedure of the patient by going against the opinion of the doctor, she needs to be assured about the impact of her decision on the health of the patient because she cannot be the responsible one for the death of the patient. However, in my opinion, Mr. Jones specially needs mental assistance from a lovable person on whom he can trust and who can give him proper support and care. If I was the assigned nurse for Mr. Jones, I would have rely on the counseling sessions which can drive away the loneliness of the patient to some extent which can also turn his attention away from his physical ailment. Conclusion In this way, the self development of the nurse who learns from the case study of Mr. Jones has been illustrated vividly. By analyzing the case study, the nurse has learnt that the health security of the patient seems to be the first most things which the medical professionals need to consider. The nurses do have the right to take quick decisions in accordance with the importance of the situation but before that they need to assure the measure from their superiors because if it cause harm to the health of the patient, the nurse will be the responsible one. Therefore, it is important to perform the professional responsibilities with dignity and guidance from the superiors at the workplace.
