An Outline of Global Climate Change on Earth

An Outline of Global Climate Change on Earth There is no doubt that the accumulating evidence is suggesting that the Earth’s climate is continually changing in direct result because of human activity. The most important of which causes the release of greenhouse gases into the atmosphere from fossil fuels. A report from the United Nations’ Intergovernmental Panel on Climate Change (IPCC) estimated the Earth’s average land and sea surface temperature has increased by 0.6  ± 0.2 degrees Celsius since the middle of the 19th century (â€Å"Climate Change 2014†). The largest parts of change have occurred after 1976. The temperature is not the only thing to change on Earth. The models of precipitation have also changed. The drier regions of Earth are becoming drier, meanwhile other areas are becoming wetter. In the regions where precipitation has surged there has been an unequal boost in the prevalence of the heaviest precipitation occurrences. Furthermore, the IPCC has concluded that if no specif ic actions are taken to decrease greenhouse gas emissions, the Earth’s temperatures will likely rise between 1.4 and 5.8 à ¢Ã‹â€ Ã… ¾ C from 1990 to 2100 (â€Å"Findings of the IPCC†). These forecasts wind speed and precipitation are not as consistent, but they also suggest significant changes. In general, humans are very accustomed to changing climatic conditions that vary on a daily, seasonal, or annual timescale. Increasing evidence suggests that in addition to this natural climate change, average climatic conditions measured over a period of thirty years or longer are also changing a lot more than the natural variations documented in the time periods of decades or centuries. As time is going on the understanding of these causes are becoming more and more understood. Climatologists have compared climate model simulations of the effects of greenhouse gas emissions to that of the observed climate changes of the past. They have also evaluated the possible natural infl uences to include solar and volcanic activity. Climatologists have concluded that there is new and strong evidence that the majority of the global warming observed over the last fifty years is most likely to be attributable to human activities. Global warming has been documented and observed in all continents with the largest temperature changes happening at the middle and high latitudes of the Northern Hemisphere. The miniscule amount of climatic change that has already occurred so far has had unmistakable effects on a large variety of natural ecosystems. Over the period 1948 to 2013, the average annual temperature in Canada has warmed by 1.6  °C (relative to the 1961-1990 average), a higher rate of warming than in most other regions of the world (â€Å"Impacts of Climate Change†). There are climate model simulations that have been used to estimate the effects of the Earth’s past, present, and future greenhouse gas emissions on climate changes. These models are based on the data of the heat confining properties of gases released into the atmosphere from man-made and natural sources. Also the measured climatic effects of other natural phenomena is used. The models used by the IPCC have been certified by testing their ability to explain climate changes that already happened in the Earth’s past. Generally, the models can give decent estimates of past patterns only when man-made emissions of non-greenhouse gas air pollutants are included to go with the natural phenomena. This underscores that the models show a good estimate of the climate system, natural fluctuations are important contributors to climatic changes even if they cannot sufficiently explain past trends on their own, and man-made greenhouse gas emissions are a vital contributor to climate patterns and are certainly likely to remain so going forward.

Harrod-domar Model for Development Research Paper

Harrod-domar Model for Development - Research Paper Example This study declares that growth is a narrower concept than development. The latter implies there is an increase in the quantity or value of the goods and services as a result of the productivity of the resources available in the economy while the former implies an increase in living standards, improvement in self-esteem needs and freedom from oppression as well as a greater choice available for the people. As growth is felt and seen in the rise in GDP of a country, development happens in the living conditions of its people through the improved access to the economic needs like education, health and recreation. Economic growth is very important but not an adequate condition for an economy to have a progressive development. The increase in the real Gross Domestic Product brought about by the growth in the economy should result to a progressive change or development which can be seen in the structural changes like an increase in numbers of infrastructures in the economy. These additiona l infrastructures may be in form of factory buildings or facilities imply additional investments. Additional investments may also mean more economic opportunities available for the people residing near where the investment was made.According to the discussion economists proposed theories to explain the importance of economic growth to development and vice versa and tried to emphasize particular patterns that each economy must pursue to attain development. II. Research Problem This paper is about one of the commonly used economic theories in relating growth and development in an economy, the Harrod-Domar Growth Theory. Specifically, this paper will present the development of Harrod-Domar Theory and the economists behind its development. Several factors that linked economic growth to economic development will also be tackled in this paper to establish the applicability of the theory. Possible effects associated with the theory will also be examined to find out if it has its significan ce or implication to the development of an economy. III. Research Objective This paper seeks to establish a deeper understanding of the Harrod-Domar Growth Theory by answering the research problem. This is important in order to explain how economies may or may not develop and how may the growth barriers be identified and overcome in the future. After relating the theory’s significance to the economic condition, it aims to form suggestions which are believed to be appropriate in the formulation of different development policies. IV. Literature Review The theory of economic growth asks what factors determine the full- employment growth rate of output overtime. It is important to study growth theory because it both helps explain growth rates and development and why per capita income level differs among countries. This part will present a brief review of the factors significant or related to economic growth.  

British Colonization Essay Example | Topics and Well Written Essays - 750 words

British Colonization - Essay Example In the 17th century United Kingdom the term "colonization" came to be utilized in a polemical manner to distinguish the domestic and local programs of the British explorer Captain John Smith. The major mistake or failure of the British colonizers, in an ancient tradition to identify themselves from the European continent, is that they did not classify their own programs to be as dominant as what people thinks. They did mention of "colonization", the transfer of individuals from the European continent to other regions of the world, paving the way to a â€Å"larger Kingdom† of English population. Majority of the British's colonies also failed to find benefits in organized, domestic colonization: great economic and industrial cartel desired for colonizing aid to secure their domestic assts against rivalry and international political conflicts overseas; bureaucrats desired and searched for government positions; people in the security wished for higher responsibilities and ranks; and the usual but striving desired for improved income for their businesses, ranks, and public office responsibilities. A distinctive success of the British colonization was the fact that it caused the emergence of fresh social perspectives of domination. Viewing the emergence of business unification, socialism, and other propaganda on the outset of a period of mass community in both the United Kingdom and later in the Western nations, the British colonizers strived to utilize imperial concepts to coordinate the aid of part of the economic working group. The re-energized mass media advocated colonization in various global wars that happened during the late 19th century and early 20th century. In the 15th century the "colonization" efforts of the British people also emerged to be connected to any ancient or traditional example of a larger authority initiating, or being viewed to be initiating a move, at the expense of a lower authority. The success of the British colonizers was therefore not only utilized to pertain to merciless territory-building programs, which include those of the Italians, the Spaniards or the English powers, but was also utilized uncharacteristically and/or disparagingly, for instance by both sides in communist and anti-communist movement, or to pertain to initiatives of the United Kingdom since the British government's takeover of outside borders on the onset of their feud with Spain, or in connection to the America's current position as the globe's most powerful country. 2.
