Is Global Warming Good or Bad

Most scientists believe that increased use of fossil fuels(coal, oil and so on) is leading to increases in global warming that will have adverse effects such as raised sea levels and the inundation of low lying coastal areas. But some scientists deny this is true, and a very few argue that the good effects of global warming will outweigh the bad ones. Take side in this debate.Advertising We will write a custom critical writing sample on Is Global Warming Good or Bad? specifically for you for only $16.05 $11/page Learn More Global warming Global warming can be defined as elevation of earth’s global temperature due to the rise in the atmospheric greenhouse gases (Maslin 9). These greenhouse gases are released into the atmosphere as a result of human activities, which include industrialization and deforestation that causes an imbalance of greenhouse gases in the atmosphere. Significantly, human combusts fossils fuels such as gasoline and coal that re leases heavy amounts of carbon dioxide into the atmosphere. When this happens, a phenomenon called the greenhouse effect arises. This leads to a blanketing effect that causes the earth’s average temperature to rise. In my opinion, global warming causes adverse effects that outweighs the positives and therefore, efforts should be invested to manage it through mitigation in order to lessen greenhouse gases emissions, adapting to its effects and through geo-engineering to eliminate the greenhouse gases out of the atmosphere. Such international efforts to achieve this are outlined by the Kyoto and Montreal Protocols. Effects of Global Warming Some scientist opposes to the occurrence of global warming claiming that indeed, the planet is cooling. Besides, they maintain that its occurrence is still unclear and maintains that global warming is a hoax and even if it was there, it could not necessarily imply a global disaster and if anything, man would adapt to its effects. However, in my opinion, this argument is incorrect since its effects are apparent. This is marked by retreating of glacier that causes rise in sea level and even inundation of coastal lowlands. Massive ices sheets have melted in the polar and mountain icecaps (Braasch Bill 27). Hence Northern latitudes experiences widespread impacts of global warming since the arctic and Antarctic poles retreat to expose tundra while oceans absorb the heat, which should have been reflected back into the atmosphere. This causes a rise in sea levels that could dislocate residents of coastal regions while rising sea levels would cause more evaporation of vapor resulting to more clouds hence rise in precipitation levels probably in regions that its unwanted causing flashfloods and monsoons (Maslin 37).Advertising Looking for critical writing on environmental studies?

The planetary surface re-eradiate the energy and transmits it as low frequency (long wave band) thermal radiation called infrared. These are absorbed by the atmospheric greenhouse gases and get scattered to emit heat energy that warms the earth surface. This process is regulated by the concentration of greenhouse gases, which have continued to rise since the industrial revolution. The earth has become warmer and climate change and its effects are now more real than ever (Oxlade 8). The greenhouse gases are carbon dioxide, methane, chlorofluorocarbons, nitrous oxides, water vapor as well as ozone (Oxlade 8). The main source of the major greenhouse gas which is carbon dioxide is combustion of fossil fuels that are used to drive daily human activities. These include transport, generation of electricity, space heating and cooking. Besides, human continue to encroach the natural vegetation through clearing of forests fo r urbanization and agricultural activities. Additionally, population growth has also contributed to global warming since they continue to clear forests and more so, they use more fossil fuels that produce carbon dioxide (Casper 49). Hence, there results an imbalance of atmospheric carbon dioxide. Greenhouse effect leads to the trapping of heat energy in the surface of the earth and average temperatures elevate. The rise in global temperatures continues to cause modifications in precipitation patterns. This could cause extension of subtropical deserts. Severe weather conditions such as heat waves and frequent draughts will result. All these changes might cause species extinction since some will fail to adapt to the changing climatic changes (Casper 131). In the recent decades, global warming is apparent and the rate in which the planet is experiencing this is unprecedented. This is reflected by computer climate models that estimate the rates at which the planet’s average tempe rature is rising. Global warming and its effects has raised controversial debates since mainstream scientists approve that the issue is a serious one that gradually becomes worse. However, some disagrees with this view that is rejected by some who insists that it is not an issue to raise eyebrows. However this standpoint seems illogic since the mainstream scientists asserts that however slight these changes are, they are accompanied by great climatic changes, which are characterized by adverse effects. The rising temperatures results to frequent droughts, flash floods and hurricanes which are remarkably detrimental to residents of precarious regions or those who rely on agriculture. Food security is threatened due to massive crop failure (Houghton 164). Water supplies will be affected leading to less agriculture while sanitation and economic growth will be impeded, not to mention the destruction of ecosystems. Global warming would cause increase in vectors that would continue to cau se diseases such as malaria even in regions that were considered free since there is a warm weather and floods for them to breed.Advertising We will write a custom critical writing sample on Is Global Warming Good or Bad? specifically for you for only $16.05 $11/page Learn More The geologic time has depicted a rise the earth’s average temperature that has varied by five degrees Celsius over millions of years. Today, scientists assert that earth’s temperature that has increased by 0.6 oC from eighteen hundreds is expected to increase by 1.4 to 5.8 oC in the twenty-first century alone (IPCC 5). This is an unusual change, which has definite effects on the planet whose life depends on i.e. ocean, hydrological and nutrient cycles. This would cause a disruption of the ecosystems that supports life by provision of clean water, food and other nutrients. Besides, it would enhance an apparent environmental stress that includes deserts, droughts, dep letion of stratospheric ozone, deforestation as well as pollution. From research, it is clear that climatic changes have to impact biodiversity, which could be lost as species get extinct. Coral populations for instance have declined due to ocean acidification and warmer conditions. This causes bleaching of these species among others that inhabits the ocean ecosystem (IPCC 5). Our civilization lies at the mercy of the global climate change. Nations have based their economy such as ports and cities along the coastal areas with the hope that water levels would be constant. But what are they getting in return? Unpredictable extreme storms like hurricanes, cyclones and tornadoes that wipe away their years of extensive labor, invested to build the economies. Global warming will cause environmental and socio-economic effects that could be very enormous. These effects are long-term and real since they can be quantified by scientists. Even if declining the emission of greenhouse gases is th e top agenda, the world must be ready to respond to these changes. The public need to become aware of the climatic changes that are to be expected and how to respond to them. These are some of the uncertainties that should be expected to be frequent as human feeds more and more carbon dioxide to the already nauseated atmosphere. To mitigate this, it is the role of all nations to draft policies that are aimed at reducing emission of these gases. Besides, the world should stop being over-reliant on fossil fuels and look for alternative renewable sources of energy. Besides, every individual has to adjust their lifestyle while planting more trees instead of cutting them down. Conclusion Current debates regarding global warming and climate change are geared at reducing emission of greenhouse gases, which is a sensible move. This is because failure to do so will cause further elevation of atmospheric greenhouse gases, which would amplify the effects.Advertising Looking for critical writing on environmental studies? Let's see if we can help you! Get your first paper with 15% OFF Learn More However, this does not necessarily require man to wait and see but has to make preparations to adapt to these changes. Adaptation together with mitigation should be complementary through proper planning that would reduce future costs (IPCC 21). Adaptive measures will be of importance since it would offer immediate help to the vulnerable groups and more benefits in future. These can be drafted to address issues such as biodiversity loss for a better and resilient future world. All the same, a great challenge lies ahead since we are uncertain about climatic changes and how man should adapt towards them. This is because there are several variables, which include rise in population, economic, technological and environmental issues that keeps on changing. This calls for an integrated approach. Therefore, let’s safeguard the natural environment today for the sake of the future of this planet we call home. Works Cited Braasch, Gary Bill McKibben.

Effective Feedback Students as Assessment Partners

Effective Feedback Students as Assessment Partners This letter will cast the light on some essential components of quality feedback as well as on the importance of feedback in primary school. What is more, it will also bring your attention to the process of achieving feedback and assessment process. In particular, it is necessary to define the quality feedback as it is identified by various scholars, and to discuss the importance of self-assessment and its role in advancing the academic achievements of students.Advertising We will write a custom assessment sample on Effective Feedback: Students as Assessment Partners specifically for you for only $16.05 $11/page Learn More So far, grading was the major tool for evaluating students’ skills and abilities. It is aimed at assessing the rate or level of students’ understanding of the subject. However, identifying the rate means pointing out students’ drawbacks and pitfalls and a failure to express a particular thought. Such system, therefore, deprives students of motivation to improve because they do not know what they should actually improve. According to Wilson (2009), the major drawback of grading tests is lack of responsiveness; grades highlight what should a student pay attention to, but not how he/she should approach the problem. You should also bear in mind that exploring the difference between quality feedback and grading assessment has led to the assumption that students’ achievements can be enhanced if using rubrics instead of scoring points (Marzano, 2009, p. 87). The scope of using appropriate scores lies in evaluating students’ achievement without interrupting the actual process of learning. Other types of assessments, like testing, do not involve a responsiveness aspect either. Smith (2009) finds it reasonable to apply for test to evaluate students’ abilities because this kind of assessment can define the way students perceive the factual knowledge. However, before introducing tests to students, teachers should be sure that a particular set of questions will involve all issues studied in class. There should be a direct correlation between test questions and learning activities and, therefore, tests should be designed for improving learning, but not for grading and decision-making. You should pay attention to Reynolds’s ideas (2009) who believes that critical evaluation and quality feedback plays an essential role in primary school education because it encourages the creation of more authentic and objective assessments (McMillan, 2011). Therefore, you should carefully select methods for assessing students in relation to learning targets and practical activities. Quality feedback, thus, should involve a multidimensional approach to evaluation. To be more precise, students should not only be objectively evaluated, but they also should also be able to critically evaluate others (Reynolds, 2009).Advertising Looking for assessment on education?

10 Helium Facts - Atomic Number 2 on the Periodic Table

10 Helium Facts - Atomic Number 2 on the Periodic Table Helium is the second element on the periodic table, with atomic number 2 and element symbol He. Its the lightest noble gas. Here are ten quick facts about the element helium. Check the full listing for helium if you would like additional element facts. The atomic number of helium is 2, meaning each atom of helium has two protons.  The most abundant isotope of the element has 2 neutrons. It is energetically favorable for each helium atom to have 2 electrons, which gives it a stable electron shell.Helium has the lowest melting point and boiling point of the elements, so it only exists as a gas, except under extreme conditions.  At normal pressure, helium is a liquid at absolute zero.  It must be pressurized to become a solid.Helium is the second-lightest element.  The lightest element or one with the lowest density is hydrogen. Even though hydrogen typically exists as a diatomic gas, consisting of two atoms bonded together, a single atom of helium has a higher density value. This is because the most common isotope of hydrogen has one proton and no neutrons, while each helium atom typically has two  neutrons as well as two protons.Helium is the second-most abundant element in the universe  (after hydrogen), though it is mu ch less common on Earth.  On Earth, the element is considered a nonrenewable resource.  Helium does not form compounds with other elements, while the free atom is light enough to escape Earths gravity and bleed out through the atmosphere. Some scientists are concerned we might one day run out of helium or at least make it prohibitively expensive to isolate. Helium is colorless, odorless, tasteless, non-toxic, and inert.  Of all the elements, helium is the least reactive, so it does not form compounds under ordinary conditions. In order to bond it to another element, it would need to be ionized or pressurized. Under high pressure, disodium helide (HeNa2), the clathrate-like titanate La2/3-xLi3xTiO3He, the silicate crystobalite He II (SiO2He), dihelium arsenolite (AsO6 ·2He), and NeHe2 may exist.Most helium is obtained by extracting it from natural gas.  Its uses include helium party balloons,  as a protective inert atmosphere for chemistry storage and reactions, and for cooling superconducting magnets for NMR spectrometers and MRI machines.Helium is the second-least reactive noble gas (after neon).  It is considered the real gas that most closely approximates the behavior of an ideal gas.Helium is monatomic under standard conditions. In other words, helium is found as single atoms of the element.Inhaling helium temporarily chan ges the sound of a persons voice. Although many people think inhaling helium makes a voice sound higher, it doesnt actually alter the pitch. Though helium is non-toxic, breathing it can result in asphyxiation due to oxygen deprivation. Evidence of heliums existence came from the  observation of a yellow spectral line from the sun. The name for the element comes from the Greek god of the Sun, Helios.

FLSA Essay Example | Topics and Well Written Essays - 500 words

FLSA - Essay Example Job titles and clear documents that describe role expectations are developed for this purpose in an effort to link job role with a salary structure. Caribou Coffee had classified workers as exempt and therefore received a salary. As part of their obligations, serving coffee and waiting on customers filled their responsibility list daily. Because of the language and/or the interpretation of the FLSA mandates, Caribou agreed to settle. The employees filing the suit argued successfully that because of their job duties, they were actually non-exempt workers (eliinc.com 2010). It would be difficult to over-complicate the FLSA by providing new amended subsections, especially if the nature of what constitutes exempt versus non-exempt were clearly defined through precedent. For example, if it included specific job role functions, the document would be unreadable and certainly irrelevant. Another case involving exempt versus non-exempt status involved Patty Lee Smith v. Johnson and Johnson in the District Court of New Jersey. The Court ultimately found in favor of J&J, believing evidence of her non-exempt status was insufficient to find otherwise (ca3.uscourts.gov, 2009). Smith worked unsupervised for 95 percent of her role, thus with considerable flexibility on the nature by which she coordinated her responsibilities. Further, no definite job role and list of obligations were present in the human resources division, thus Smith could not prove otherwise considering the evidence of her status that are most closely associated with a person in a salaried, executive level role. It was a common sense ruling, however the language of the FLSA is open to even judicial interpretation due to the lack of practicality in constructing supplements. These situations can be avoided in the future by fully categorizing the job title and the specific responsibilities, or ensuring that a sign off

Human resouces management is nothing more than personal management Essay

Human resouces management is nothing more than personal management with a new label, Critically evaluate this statement - Essay Example Consequently, the concept of labor power that was sold by human beings had to be effectively organized. Hence, owner of firms and organizations began adapting to the world of management through the use of personnel management that had the sole responsibility of hiring and firing employees. Actually, employees welfare demand grew by the day, the world of management grew simultaneously to the extent that the personnel management could not accommodate the increasing demand for employees’ welfare and as such, most organizations and firms began replacing personnel management (PM) with human resource management (HRM). Apparently, the term human resource management has been used across the world for approximately a century. According to Soni (2013) the emergence of Human resource management (HRM) is believed to have started in England in the early 18th century when the west was experiencing the apprenticeship and craftsmen era. Moreover, the emergence of HRM was also significantly associated with the arrival of the industrial revolution. As the 19th century begun, a philosopher by the name Taylor argued that it was necessary to combine scientific management and industrial workers psychology, and further introduce the two concepts in the business world. In light of this, the philosopher further articulated that it was imperative for workers to be managed not only for the purpose of making work to be efficient, but also ensuring that the workers were psychologically fit to hold the title of being employees. Similarly, the drastic changes that were being witnessed especially in technology, growth of various organizations and the rise of different unions greatly facilitated the development of personnel departments that were run by welfare secretaries soon after the beginning of the 19th Century. Importantly, the effective management of human resource in any organization is to ensure that competitive advantage is gained in the marketplace.

Stealing Home Can you imagine living somewhere all your life, and then having a stranger tell you to move? What about having you home taken away from you because you live differently then others? Or even yet, can you imagine having someone move in next door to you, and you die from a sickness that they brought with them? Native Americans have lived this way since the days of Christopher Columbus. As they were shuffled around and pushed westward, the crowd followed, until there was nothing left for them. American Indians roamed the lands of America long before settlers from Europe even dared to travel across the oceans. They lived from and with nature, respecting the laws of life, and cherishing every aspect of their civilization. They hunted and fished, using each part of their prey, wasting nothing. Bones were used for weapons; hides, for clothing and shelter. They lived simply. It was impossible to tell that their worlds would be turned upside down. When settlers first arrived in America, they were greeted by Native Americans. They helped the settlers learn to live the way they did – to use nature to its fullest and to respect it. Meanwhile, millions of Indians were dying from the diseases brought over from Europe. Indian villages were burned to stop the spread of disease. The settlers were scared of these diseases that no one seemed to understand. They blamed the Native Americans for deaths of settlers that were due to the diseases. This blind blame would be seen later in history, as the railroad invaded the territory of the Native Americans, and they were again blamed for death and warfare. Between the beginning of the Civil War and the Gold Rush of 1849, thousands of emigrants had been crossing the plains in search of gold. The Indians of the North-west generally accepted the government policy that the land west of the Mississippi River was theirs, and they expected settlers to stay out. Of course, the pioneers needed to cross that territory, which the Native Americans considered sacred hunting grounds (Schmitt 2). The Native Americans first learned of the railroads by runners – those who ran the land to learn of gold seekers and settlers moving across the territory. They called the railroad the "iron horse on the iron track," and as it moved across the Mississippi, it was evident to them that once again, their land would be taken (Schmitt 6-7).

Compositions Essay

My parents took me to Chidambaram on the occasion of the festival for Lord Nataraja. That festival occurs once in a year. The crowd was huge. It had come from all parts of India, and, in some cases, even from outside India. The crowd consisted of people from various states in India. It therefore, consisted of people from different walks of life. We saw people from Northern states of India, like, Uttar Pradesh, Rajastan, Delhi and many more. We also saw crowds from Great Britain and The United States of America. We found people talking in different languages. Some of the people found it difficult to make the local people of Chidambaram understand what they meant. So, they needed interpreters. As mentioned earlier, the crowd was not only huge, but consisted of citizens of various status and from various states. Some leader was delivering a speech. He did not belong to Tamil Nadu. Sometimes he would speak in broken language and then switch over to different language, which i too could not follow. The crowd was in no better position. So, there was commotion in the crowd because it could not understand what the speaker was talking about. When the crowd became restive, someone came on to the dias to do interpretation, but that did not also satisfy the crowd. Therefore, the speaker finished his speech and some one else came up the dias to deliver the speech. But, he too did not understand the local language well and there was a confusion again. This time the crowd became very restive and could not be controlled by the cops. When the situation appeared to be going out of control, the cops interfered and used water guns to disperse the crowd. When that too did not give the desired result, the cops naturally resorted to using bullets. The first fired in the air to terify the people. But, that did not yield the desired result. So they sprayed the crowd with actual bullets. This made the crowd retreat and some calm appeared to have descended on the crowd. So, this was a meeting which was well attended. But, it was attended by people from various states speaking different languages and having different life cultures. The speakers also did not do anything to pacify the crowd. As i said earlier, the crowd came from different states and spoke different languages, they could not understand what the speakers spoke, nor could others understand what they spoke.
