Extract of sample "Events and Impacts of Climate Change"

Download file to see previous pages Singh et al (2007) describe 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, the variation of the tilt angle of earth’s axis of rotation and the earth’s axis precession. Climate change causes variations in solar radiation. It has triggered little ice age, and temperature increase observed in the 1900s to 1950s. Volcanism is a significant factor that triggers climate change. Wignall (2001) asserts that volcanic eruptions 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) assert 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 greenhouse 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). ...Download file to see next pages Read More

...?Climate Change Introduction Climate change continues to be a problem not only by several individuals or nations, but rather it is a dilemma for the entire globe. As global warming speeds up, climate change also picks up its pace, a threat from nature to mankind which would yield undesirable effects. Although it is a devastating dilemma, we are not left hopeless. Climate change urges rapid modifications on how we run our systems by altering our individual lifestyles, establishing legislation as the nation’s aid, and participation of other countries in this endeavor. Individuals Human activities are frequently blamed as root causes of climate change. Similarly, human beings can clean up this mess through little ways. When we are aware...

Climate Change

Extreme temperature is not suitable for sustaining life forms on earth. If the temperature rises beyond certain limits, survival of humans and animals on this earth would be difficult. It should be noted that there is equilibrium, with respect to the quantity of oxygen and carbon dioxide in the atmosphere. Trees and plants absorb carbon dioxide from atmosphere for photosynthesis and they liberate oxygen when the process is over. On the other hand, human and animals breathe oxygen and liberates carbon dioxide. Thus, the atmospheric content of oxygen and carbon dioxide follows a ratio all the time. However, when atmospheric temperature increases, survival of trees and plants would be difficult and thereby the ratio of oxygen with c...

The impacts of events

Tourists’ focus then started to shift with the advancements in the event industry. As event planners came into the picture they realized that the tourism industry needed social events which lead to the event tourism industry (Lim & Lee, 2006). People usually travel to destinations for leisure and relaxation purposes but there are also people who travel to destinations for the purpose of business meetings, conferences, workshops and other similar social events. This movement of people has given rise to the event tourism industry (WTO, 1995). Events and tourism now go hand in hand, and so one without another seems incomplete. The perfect way to describe tourism would be to say that it takes a systematic planning process along with...

Even though the roots of this problem are worldwide, the detrimental effects of climate change are excessively affecting indigenous peoples. Different populations have confronted climate change and adjusted to it since the evolution of species. The vast majority of that period is forgotten and can merely be recreated through proxy or archaeological studies, which have a great deal to contribute to current knowledge of earlier human alleviation of and adjustment to climate change. According to archaeologists, food storage is widespread and sharing or reciprocity is integral to survival during...

... Global warming Climate change is the effect brought about by the production and emission of greenhouse gases such as carbon dioxide, methane, and nitrous oxide, into the atmosphere, which causes entrapment of heat, which is fleeing the earth, thus causing overall rise in regular temperatures of the earth (Seymour 15). It is one of the most pressing issues in today’s world as it affects the natural settings and balance of the earth’s ecosystem, which is consequently, affects human beings (Houghton 44). They are various causes of this global warming, natural and man-made with the latter being highly blamed, but how do human actions impact global warming? The human factor is highly credible in causing this climate change. One of the human...

Adaptation Response Climate change is a threatening aspect all across the globe. It will continue to change in the coming centuries at unprecedented rates in the recent human history. Therefore, adaptation to climate change is an emerging subject in the modern world (Lo 2012). Adaptation simply refers to the steps put in place to reduce vulnerability and building resilience. This implies that adaptation is the management of the risks posed by climate change with respect to the mitigation decisions revolving around the environment, economy and the future generations (IPCC 2014). This is because vulnerability results from loss of resilience in a system, but resilience is about the level of capability of the people which is limited t...

Climate Change Impacts & Trends

...Climate Change (Impacts & Trends) Climate Change (Impacts & Trends) Background A Swedish scientist d Svante Arrhenius gets the credit for pioneering the awareness on issues related to global warming when he proclaimed in 1896 that combustion of fossil fuel would enhance global warming. Global warming is the long-term and short-term influence on the climate that leads to increased greenhouse gas emission causing adverse impacts on the biological and physical systems. The menace is referred to as global warming because temperatures rise above the normal limits to melt the snows leading to rise in sea levels and ocean acidification (Figure 1). People did not take global warming seriously during 1900 because human activities were insignificant...

Ways to Implement Change within an Organization

This paper will discuss some of the reasons why people are against change. It will also discuss some constructive ways and give tips for managers on how to move people towards a more accepting position that will be more beneficial to the company’s changing times.
Kegan and Lahey (2001) wrote that the reasons why employees resist change may be because of several reasons. These employees could be scared when new leaders are assigned to them and control is passed on to new people. They are forced to be proficient in an entirely different ability even though most of the time old dogs cannot be taught new tricks. It is hard enough to master the current skills needed for their jobs but to learn even more new skills can be dau...

Change Management

...Introduction Change is an aspect that cannot be ignored in any given organisation yet the human instinct naturally opposes change. Change usually occurs frequently and at a rapid pace. Consequently, those who tend to resist it may slow down an organisation or even destroy it altogether. Resistance to change usually occurs as a result of the natural tendency to maintain status quo. Human beings generally have an inclination towards stability and this means that organizational change may be regarded as something that will cause instability. Usually, employees may begin depicting some signs of resistance through scepticism. This kind of behaviour creates a barrier that may make it extremely hard to implement organisational change. In light...

Contemporary Issues in World of Politics Climate Change Policy

It is more than a particular problem of any specific community. In fact, climate change has a wider global nature compared to other environmental issues and it affects the people of every nation and boundary. Therefore, the issue of climate change has a far wider reach than the other environmental issues and it is an issue concerned with almost all the international communities. It is identifiable that national boundaries may attempt to prevent the movement of people and goods across the boundaries of the nation. However, when it comes to pertinent environmental issues such as climate change, these issues do not stop at borders, making them – some would argue – quintessentially global phenomena. “Climate change i...

In What Ways Did 20th Century Conflicts Change the Nature of Western Introspection

The 20th century period was marked by several conflicts: World War I, the Holocaust, World War II, the exploitation of Latin American countries, Racial Segregation and the Negro Revolution which spawned the Civil Rights Movement in America and the Feminist Movement.

The Holocaust is admittedly one of the most horrific events in the history of mankind and the impact of the horrors it brought changed the way Ellie Wiesel sees his faith. While Jews are known for their orthodox and unquestioning faith in God, Wiesel’s experiences in the concentration camps of Auschwitz compelled her to question God’s existence. In Night, Wiesel tells of the unspeakable hanging of a young boy who was left dangling for thirty min...

Introduction to Change Management

Management often follows a “change management process” to change the existing process or activity.
Change management is a systematic approach for dealing with change that takes place in the organization as well as at the individual level. Such change management comprises of three aspects: adapting change, controlling it and finally affecting it. These three aspects of change management were well explained in three stages of change model given by Lewin (1952) and the three stages are “unfreezing”, “change” & “refreezing” (Orlikowski & Hofman, 1997). Another model for change was introduced by Prosci after conducting a research on more than 1000 companies from 59 countries....

The Quantum Change: Gradual Epiphanies in Two Novels

Although they might not seem very sudden to the reader, the necessary changes occur during the second part of each novel, and so qualify them in a literary sense as epiphanies.

Part A: The first novel is a first-person narrative, in which Ditie, a man of small stature, endures what might seem like a hard life in wartime Prague. Although at first reading, Ditie does not seem to have a complex or hang-up about his size, most of his experiences and stories are tinted with descriptions and narrations that seem to have this aspect of his appearance in the background. All through the book, the reader is aware this is a very small man who, although he does not try to compensate overtly, and seems all in all to accept his short...

Multiculturalism: Socio-economic Impacts on Modern States

This paper tends to argue that multicultural policies have promoted social segregation and economic insecurity in modern states. As the most relevant example, it will also evaluate how multicultural policies have evolved to be the most recent threat to the nationality and cohesion of Australia and the United Kingdom.

To begin with, many of the policies enacted on citizenship and immigration have brought about incessant controversy in Australia. In addition, the exceeding emphasis put on the multicultural policy has given rather unfavorable outcomes to both Australia and the UK. Policies that are intended to ensure equal representation and opportunities often create frustration and disappointment among certain interest g...

Analysis of Articles about Climate Change

...-220) contradicts the findings of the first IPCC report (Houghton, Jenkins and Ephirams, 1990). It removes the element of predictability from the whole scenario of global climate change. But still, it warns us of a possible climate change as Houghton, Jenkins and Ephirams (1990) did, but for different reasons. A limiting factor of this study is that it overlooks the impact of green house gas emissions artificially created by humans and do not try to see whether there is a link between this and the warming patterns in the present interglacial in which there is a lot of aggressive human intervention. Of course, such an enquiry does not come under the scope of this study but people with vested profit motives could make use of these findings...

Organizational Change and Development at IBA

The results revealed that the employees had no incentive for working in an innovative way and they were not compensated in the right manner. The clients were not given any incentive to return, therefore, most of them went to the competition. The employees working over three years were given special benefits if they sign a contract to work for the organization for at least 3 more years. Employees were given training sessions for better customer experience. Informal dinner or lunch each was scheduled each month in order to enhance the level of communication in the organization. Ten months after the implementation of these changes, the consultants returned for evaluation and found that the results have shown a successful change in th...

Globalization and Business Enterprise: Climate Change

Since globalization encompasses political, economical and environmental issues, there has been much debate amongst companies on how resources are to be allocated in order to minimize climate change. Climate change is being dealt with on a global scale. The “Green investing is on the rise”, where investors are buying stocks that are environmentally friendly. New Zealand, like other countries, is supporting the cause for environmental protection by legislative measures in trade, bills regarding carbon emissions and by being part of agreements with the UN and the Kyoto Treaty.

Climate change and globalization are intricately linked. With the passage of time, many environmental issues, like global warming, have...
