Events of climate change and impact of climate change Essay

Events of climate change and impact of climate change - Essay Example (2007) describes climate change as the statistically substantial variation in the mean condition of climate (p.145). Climate change has also been described by Maunder (1992, p. 34) as a change in climate ascribed directly or indirectly to human activity that changes the global atmospheric composition observed over a period. Ocean variability, solar radiation variations, plate tectonics, volcanic explosions, human activities and orbital variations cause climate change. Oceans are vital and critical elements of the climate system (Christopherson, 1992, p.223). Short-term changes in oceanic oscillations cause climate variations. Modification to ocean processes plays a significant role in spreading heat through slow and deep water movement. Differences in earth’s orbit positions cause seasonal changes in sunlight distribution (Christopherson, 1992, p.222). There are three types of orbital variations i.e. earth’s eccentricity variation, variation of the tilt angle of earth’s axis of rotation and the earth’s axis precession. Climate change causes variations in sun radiation. It has triggered little ice age, and temperature increase observed in 1900’s to 1950’s. Volcanism is a significant factor that triggers climate change. Wignall (2001) asserts that volcanic erupti ons emit carbon dioxide causing immense effects on the climate (p. 21). Forest et al. (1999) assert that plate tectonics affects local and global patterns of climate and atmosphere-ocean circulation (p. 23). Solomon et al. (2009, p. 1705) asserts that human activities leading to increased carbon dioxide emission are the key factors contributing to climate change. Effects and Events of Climate change Climate change still remains to be a global hazard since the green house gases continue to increase across the world (McCathy, 2001, p. 124). Climate change has adverse effects on the environment, ecological systems and the social systems (Cline, 2007, p. 145). Climate change increases or

FINAL EXAM - Essay Example They are less important for managing or hedging against short-term exposures because demand uncertainty is always lower in the short term. In addition, operational hedging is likewise less crucial for commodity-based firms that face price rather than quantity uncertainty. Financial instruments are greatly used by forms to hedge against short-term exposures while operational hedges are used greatly to hedge against long term exposures. The foreign currency cash flows of firms that have plants both in foreign and domestic location are not independent of the exchange rate. And therefore, optimal financial hedging policy should entail forward contracts as well as foreign currency put and call options. Natural hedges helped MNCs to offset unexpected fluctuations in foreign currency exchange rates especially operational hedges that are associated with geographical diversification. Operational hedging often compliments financial hedging. For instance, MNCs use financial derivatives to mitigate risks exposures while they are operationally hedged, geographically diversified. Financial instruments are used to reduce the basic component of profit variability while geographical diversifications (operational hedges) can reduce firm-specific risk exposures. The use of both financial derivatives and operational hedges improves firm value. Operational hedges are not perfect substitutes for financial risk management. In the case of CARREFOUR S.A., Carrefour used financial market instruments, Forward contract, to hedge against their foreign currency borrowings in order to maintain total debt requirements at 97% in Euros. MNCs often use both parallel loans and currency swaps to achieve a similar objective. For instance, they provide a cheaper form of debt because they easily borrow in their respective countries and then swapping the debt. Both parallel loans and currency swaps helps the MNCs in

Energy in American History Essay Example | Topics and Well Written Essays - 1250 words

Energy in American History - Essay Example In fact, there was less reliance on the wood for fueling locomotives after discovery of coal. Moreover, there was a high preference for coal as a source of energy was due to its higher-energy content compared to wood. Coal was needed for production of coke in the process of manufacturing iron and steel; in fact, it was identified as an economical component in the production process. Nevertheless, the paper will focus on exploring use of energy in America through a comparison of different sources, while the next section will summarize arguments in these sources, thereby evaluating them to determine whether they are honest and accurate. Finally, the paper will explore the historical context for energy issue and discuss the way knowledge can influence evaluation of these arguments. There was profound growth of energy consumption in the transport sector during the nineteenth century, and this growth led to an exhaustion of sources of energy such as wood and coal, in American history. How ever, this was not until the Second World War, when petroleum was introduced (Johnson, 30). Establishment of petroleum let to a shift from use of coal as a source of energy to use of diesel and gasoline on locomotives and trucks. This was also facilitated by engines designed to consume gasoline and diesel, thereby making petroleum products predominant sources of energy for transportation. Nevertheless, this led to a rise in labor issues, safety standards, increased costs of coal production and a reduction in the use of coal as a source of energy. Years later, there was a reemergence of coal consumption as a source of energy, which involved firing electrical generators; this clearly indicated its stake as source of energy. However, introduction of petroleum as a source of energy and natural gas continued to reduce use of coals as a prime supply of energy. There was a further increase in the use of petroleum in the 1920s after a completion of the first petroleum drilling project by Ed win Drake (WOU, 1). In fact, this led to a significant increase of use of petroleum during the depression, which increased until 1973. In this case, petroleum can be considered the only source of energy that underwent sudden increase in consumption during the American history. Issues and arguments at this section of the paper entails a comparison of two sources from both governmental and non-governmental website, and these sources seem to agree in numerous accounts regarding changes in the consumption of energy in American history. Therefore, these accounts can be considered rational, and with an attribute of high level of accuracy. Consequently, this makes the stance of the paper to be in agreement with the accounts provided by these sources in relation to the history of energy consumption in America. Evaluation of the Arguments There has been a notable change in the patterns of energy consumption over the American history throughout the development of different sources of energy a nd change of energy consumptions. Therefore, the arguments proposed in the first section of the paper can be considered rational and accurate. In fact, there are other websites indicating that wood was used as a source of energy before establishment of coal, which was later replaced by petroleum. In this case, accounts by these sources indicate that coal was a highly preferred source of energy during the nineteenth century. Moreover, different sources also indicated that in

A Students’ Involvement Encourages Good Grades :: Research Statistics Essays

A Students’ Involvement Encourages Good Grades The Purpose of this Report The purpose of this report is to illustrate that teens that are involved in extra-curricular activities generally get higher grades than those who are not involved in activities. Some of the research for this report was acquired through the Internet and some of it was obtained through surveys of 120 high school students, grades ten through twelve (see Appendix A). All of the sources that talked about this subject suggested that there is a strong positive correlation between extra-curricular activities and good grades. Although some students are different, this has proven true in the general classroom as well as in a high school talented and gifted class, a high school English class, and a high school art class. The main reason that this correlation exists is because of organization skills, parents’ involvement, and the need these students have to excel. Results in the General Classroom It used to be believed by experts that one should study and not play. This is no longer the case, according to Mr. R. Griffin in his article Helping Athletes Excel in Sports and School (23). He suggests that it is important to encourage both academic and extra-curricular performance. In most instances, involvement in extra-curricular activities leads to better grades. According to the University of Michigan, teens that are involved in activities during high school are more likely than teens that didn’t participate in any organized activities to have higher grades as high school seniors and to still be in college six years later (Swanbrow 1). These results were produced at the University of Michigan by tracking 1,259 sophomores for six years. These results also proved to be true in the three individual classrooms that were surveyed. The classes that were surveyed were students in art, talented and gifted, and English at Southeast Polk high school. The results are shown in the f ollowing three paragraphs. High School Talented and Gifted Class A group of students, grades ten through twelve, in the Talented and Gifted program were surveyed to see if the positive correlation between involvement and grades held true. According to this particular survey, it was shown that ninety-six percent of students were involved in extra-curricular activities. These activities ranged from basketball, wrestling, football, swimming and track to National Honors Society, Bible study, speech, drama, and student council. Out of the ninety-six percent of people involved in activities, the average grade point was 3.

Suggest reasons why the memberships of trade blocs, such as the EU, has changed over time

Memberships of trade blocs changed over time because countries realized that there are a huge amount of benefits to joining a trade bloc union. Benefits such as Free trade within the bloc which means that they have free access to each other’s markets, members of the trade bloc are encouraged to specialize. This means that at the regional level there is a wider application on ability to carry out a particular economic activity e. g. making a specific product more efficiently than another activity.In addition countries have Market access and trade creation which is when countries have easier access to each other's markets meaning that trade between members is likely to increase. Trade creation exists when free trade enables high cost domestic producers to be replaced by low cost and also allow more efficient imports. Because low cost imports lead to lower priced imports, there is a ‘consumption effect', with increased demand resulting from lower prices.Also Producers from the member country can benefit from the application of scale economies, which will lead to lower costs and lower prices for consumers. Jobs may be created as a consequence of increased trade between member economies. There is increased protection. Firms inside the bloc are protected from cheaper imports from outside, such as the protection of the EU shoe industry from cheap imports from China and Vietnam. There are other long-term political and social benefits to trade blocs.The countries’ economies become more intertwined also the political reasons for close cooperation within the bloc increases. Countries understand that they have a stake in each other and make greater efforts to get along. In that same way, increased business contacts usually mean that people must learn the culture of their trading partners. Many must learn new languages and different business practices. In short, more people will come into contact with each other and will need to learn more about each oth er. This breeds increased understanding amongst people.Another reason for the change is as for consumers are that there is often a greater variety of goods and services available in free trade blocs. Products like beer, detergent, clothing, and machine tools are often produced in all the countries after the free trade agreement they are often stocked in many stores. Products like satellite hook ups for televisions, computers and telephones are usually made more available to developing countries. Internet service providers are now able to sell to larger markets and more consumers have opportunities to purchase or use these services.
