...Human activities affect the change of climate There have been various changes in the climate. Extreme events such as the Nashville flood which is described by officials as a once-in-a-millennium occurrence are happening more often than they used to be. Human-made shift in climate and purely natural factors may conspire those events. Whereas in the past, extreme events was a relatively rare occurrence, in recent times it has become quite commonplace. The anthropogenic factors may play a major role. Of most concern in these anthropogenic factors is the increase in CO2 levels due to emissions from fossil fuel combustion, followed by aerosols and cement manufacture. Other factors, including land use, ozone depletion, animal agriculture and deforestation, are also of concern in the roles they play - both separately and in conjunction with other factors - in affecting climate and measures of it variables. According to a number of surveys the Earth is becoming increasingly warm in past years. This is also expressed as global warming. The human activities such as burning fossil fuels have increased abundance of small particles in the atmosphere. These particles can change the amount of energy that they absorb and reflect (Hamburg et al. 2012). In consequence the concentration of particles makes it difficult for the reflected solar energy to radiate. Beyond that, the gas produced by burning fossil fuels such as carbon dioxide and methane is widely considered as the major factor...

...WRITING ASSIGNMENT Topic: To what extent do you agree or disagree with this statement. Human activity has been a major cause climate change. People have substantially contributed to the multiple direction development of the world. They have entirely composed the world better and better. However, what human have done for their environment contributing to the destroyable life in recent decades in terms of climate change. Climate change can be defined as the long- term shift in weather conditions identified by changes in temperature, precipitation, winds, and other indicators. Climate change is caused by many factors, therefore, to some extent, human activity has subsidized to the effects of climate change on people’s life with two primary causes: industrial activities, and land use changes. Firstly, the development of industry for recent year has mainly risen the dangerous level of climate change. Constantly, the huge number of Carbon dioxide has been emitted to the atmosphere by resulting from automobiles, industry, electric power plants. Electricity is considered as the main factor causing CO2. The reliable prediction is given that manufacturing electricity in the future will cause the increase CO2 emissions from 10 billion tonnes per year to 12.5 billion tonnes per year (Climate Change – The Science. 2014) . The high Carbon dioxide rate directly effects on the changing of climate process. Human-related emissions are responsible for the increase that has occurred in the atmosphere...

...What is climate change? Climate change, or global warming, is the gradual increase of the temperature of the earth. Climate change has been a topic that has been talked about for awhile now. If it is happening, if it is not, if humans cause it, and if it is happening naturally. Humans could be causing it by the many things we do, but the earth could be going through natural cycles which is causing climate change. There is evidence to support all of these arguments. Even scientists are having arguments about whether it is occuring or not. It’s weird to think that so many people, like scientists, disagree on one thing. Some people think that climate change is caused by humans. Some ways humans can cause climate change is by deforestation, burning fossil fuel, driving cars, even breathing. Of course breathing isn’t the biggest contributors to climate change but it contributes some. And then some people think that climate change is happening naturally. Things that would cause this would be volcanoes, and some of the natural cycles that the earth goes through could cause climate change. Then, there are people who think that climate change is not happening. I am going to tell you everything that you should know about climate change. There is a lot of evidence that shows climate change is happening yet some people still believe that it is not happening....

...Most of the scientists agree that this climate change is threatening our earth; human beings can be extinct probably in the near future. The cause and effects of this phenomenon has been studied which is greenhouse effect. The whole world is getting involved in this issue and looking for solutions. Greenhouse effect is a natural phenomenon that increases temperature of the earth’s surface (Australian government). However, according to the investigations, human activities enhanced the greenhouse activities, making it worse. So our climate change is due to the increasing human activities, global industrialization which ejects huge amount of carbon emissions. Human activities enhance greenhouse effect that causes widespread heave rainfalls in the northern Hemisphere during the last 50 years (Minetal, as cited in Allan, 2011).The rising temperature is disrupting every aspect in our life and the whole ecosystem. This climate change affects atmospheric and ocean circulations and brings many hazards to the earth, such as widespread drought, flood and tsunami. As we considered climate change, we need consider the common good for all the humans on the earth. The common good refers to the total living conditions which can enable individuals to get the achievement which enables people to achieve humanity (google), whereas climate change is a serious issue that is eliminating human living resouces in many aspects. As we mentioned above, climate change can cause many negative effects, such...

...“Human activities contribute to climate change by causing changes in Earth’s atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to the atmosphere. Greenhouse gases and aerosols affect climate by altering incoming solar radiation and outgoing infrared (thermal) radiation that are part of Earth’s energy balance. Changing the atmospheric abundance or properties of these gases and particles can lead to a warming or cooling of the climate system. Since the start of the industrial era (about 1750), the overall effect of human activities on climate has been a warming influence. The human impact on climate during this era greatly exceeds that due to known changes in natural processes, such as solar changes and volcanic eruptions.” IPCC, 2007: Climate Change 2007: The Physical Science Basis. Contribution of Working Group I to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change [Solomon, S., D. Qin, M. Manning, Z. Chen, M. Marquis, K.B. Averyt, M.Tignor and H.L. Miller (eds.)]. Cambridge University Press, Cambridge, United Kingdom and New York, NY, USA. I do support climate change as a human-caused event. Although it occurs naturally, humans have played a huge part in the advanced onset of climate change. “ Human activity is causing the Earth to get hotter primarily by two actions: Burning fossil fuels, with a smaller...

...secondary and tertiary sectors. However, farming remains vitally important to the economy with 638 000 people formally employed (Statistics SA, 2012 Q2) – although it’s estimated that around 8,5-million people are directly or indirectly dependent on agriculture for their employment and income. However, global climate change will affect the government’s efforts to alleviate poverty and fast-track development in rural areas. Definition of terms Global warming: refers to the increased temperature of Earth's surface, including land, water and near-surface air. Climate change: means a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods (UNFCCC). 2. Causes of Climate Change Any factor that causes a sustained change to the amount of incoming energy or the amount of outgoing energy can lead to climate change. They are factors that operate in favour of climate change; these factors that cause climate change can be divided into two categories. Those related to natural processes and those related to human activity. 1|Page...

...greenhouse gases caused by human activity is often cited as one of the major causes of global warming. These greenhouse gases reabsorb heat reflected from the Earth's surface, thus trapping the heat in our atmosphere. This natural process is essential for life on Earth because it plays an important role in regulating the Earth's temperature. However, over the last several hundred years, humans have been artificially increasing the concentration of these gases, mainly carbon dioxide and methane in the Earth's atmosphere. These gases build up and prevent additional thermal radiation from leaving the Earth, thereby trapping excess heat. Solar Variability & Global Warming During the initial discovery period of global climate change, the magnitude of the influence of the Sun on Earth's climate was not well understood. Since the early 1990s, however, extensive research was put into determining what role, if any, the Sun has in global warming or climate change. A recent review paper, put together by both solar and climate scientists, details these studies: Solar Influences on Climate. Their bottom line: though the Sun may play some small role, "it is nevertheless much smaller than the estimated radiative forcing due to anthropogenic changes." That is, human activities are the primary factor in global climate change. Solar irradiance changes have been measured reliably by satellites for only 30 years. These precise observations show changes of a few tenths of a percent...

...Human activity has become so widespread, invariably contributing to the changes in global climate, which are consequently having a negative effect on weather patterns and the frequency and severity of weather related natural disasters. Global warming has become alarming recently. Over the past decades, research has been conducted on climate change and its impact and how it directly or indirectly influences the health and well being of the planet and its inhabitants. This essay will cover the risk and impacts of climate (weather) – related natural disasters such as storms, floods, droughts, rainfall and extreme temperature. Research over the past few decades has done much to clarify the evidence that global climate is changing and these changes are largely due to human influence. Intergovernmental Panel on Climate Change(IPCC),(2014) linked the risks of climate change to the increase in emission of greenhouse gas through human activities resulting from increased in population and economic growth. According to World Health Organization (WHO), (2014) the increase in human activities has impose dextra force on the climate system, most especially the burning of fossil fuels result in the emission of greenhouse gases and carbon dioxide. They accumulate and cause extra heat on the surface temperature, increasing the climate variability and influencing climate change.As the atmosphere accumulates energy, it yields to the increasing greenhouse gas concentration causing climate change...

...claustrophobic? Furthermore, are changes in atmospheric composition and global climate the result of human activity or natural processes? There is much evidence backing up either side and showing that the change could be the result of both. However, because of many factors, I believe human activity is the cause of change in atmospheric composition and global climate. Human population, man-made processes, and deforestation have a great impact on atmospheric composition and global climate change. The first trace of human civilization was in Mesopotamia, in which we know had different cities. Historians estimate that there were about 96,000 people in these cities. The human population of the world is now seven billion and counting. Historical records show that in 1997 there were approximately 365,000 babies born everyday; 140,000 people die each day; this gives the world a natural increase of 220,000 people everyday. The increase in population obviously means a rise in human activities. Gradually over time, the Earth’s climate has changed and so has atmospheric composition. To clarify one thing that will be stated throughout: changes in atmospheric composition cause changes in climate. An increase in human activity causes more likelihood for change in the atmosphere. More people on Earth means more human activity. If there is more harmful (to the environment) activity there will be a greater change in atmospheric composition and climate. With more humans being produced and survival...

...Causes of Climate Change Climate change is a long-term shift in weather conditions identified by changes in temperature, precipitation, winds, and other indicators. Climate change can involve both changes in average conditions and changes in variability, including, for example, extreme events. The earth's climate is naturally variable on all time scales. Factors that cause climate change can be divided into two categories - those related to natural processes and those related to human activity Natural Causes The Earth's climate can be affected by natural factors that are external to the climate system, such as changes in volcanic activity, solar output, and the Earth's orbit around the Sun. Human Causes Very few people doubt that it is normal for there to be climate change. The rotation of the earth on a tilted axis leads to this, as well many natural events, like volcanic eruptions, earthquakes and hurricanes. However, human activities are having a much greater impact on climate change. For example, the jump in earths’ population from 1950 through 1985 more than doubled from 2.5 billion to over 5 billion. (Meyer, 1996: 24) The importance of this growth is a drain on the Earths’ resources causing even more altering. It is not as much the altering of these resources that are causing climate change but the type of human activities which are taking place, and the way in which they are impacting the climate. The earth is naturally surrounded by gases the added human processes...

...Climate Change: Causes, Effects and Solutions HUSSEIN KALAKESH ENG 101 Baker College of Allen Park Climate Change Essay UIN# 107-24597 Climate Change: Causes, Effects and Solutions Nowadays climate change is the biggest problem of the human being. It is already happening and represents one of the greatest environmental, social and economic threats facing the planet. The climate can affect every person and our health directly through increases in temperature. Such increases may lead to more extreme heat waves during the summer while producing less extreme cold spells during the winter. Particular segments of the population such as those with heart problems, asthma, the elderly, and the very young can be especially vulnerable to extreme heat. There can be extreme floods and droughts, hurricanes. The warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global mean sea level. The Earth’s average surface temperature has risen by 0.76° C since 1850. Most of the warming that has occurred over the last 50 years is very likely to have been caused by human activities. In its Fourth Assessment Report projects that, “without further action to reduce greenhouse gas emissions, the global average surface temperature is likely to rise by a further 1.8-4.0°C this century, and by up to 6.4°C in the worst case scenario”. Even...

...Human Activities must not be considered as a Substantial Cause of Global Climate Change ‘’Our world is always changing, Constantly re-arranging. From ocean depths to mountain peaks, Mother Nature moves and speaks. While telling stories of our past She tries to teach us how to last.’’ Change- the only thing in the universe that is constant. Starting from the journey of childhood, we are witnessing changes, whether it is about our appearances, lifestyle or about living environment. The words of Phinazee also portray the image of change, specifically in Mother Nature. She conveys her love to the greenery, the beauty of ocean, the openness of mountain peaks and valleys. Sadly, these generosities of nature are some footprints of past times. Today, the world is facing major behavioural change in natural environment. The crisis has started to affect even our future generation. It is undoubtedly a threat to our existence. One of the major issues responsible for the crisis is global warming. Global warming is the gradual yet constant increase in the earth’s overall temperature mainly associated to increased level of greenhouse gasses and other pollutants (Oxford Dictionaries, n.d.). The front scene indicates human activities as the main culprit of global warming but the facts behind the front scene should also be considered to get the whole picture. As these facts identify global warming as partially a natural occurrence, change in global climate pattern must not be considered...

...Climate change is refers to the rise in average surface temperatures on earth, mostly due to the burning of the fossil fuels such as oil and coal, which emits greenhouse gases into the atmosphere which are primarily carbon dioxide, water vapor, methane, nitrous oxide, and chlorofluorocarbons (#02). In addition, other human activities, such as agriculture and deforestation, also contribute to the growth of greenhouse gases that cause climate change (#01). According to this, many have make their own conclusions on how are humans responsible for climate change and whether or not it is a real thing. Some people think and guarantee that climate change is real and it is happening at least in part because of human activity. This people argue that in the last 100 years, carbon dioxide concentrations in the atmosphere have risen from 290 parts per million (ppm) to 369 ppm, with strong evidence pointing to the burning of fossil fuels by humans as a primary cause of these increases (#03). Additionally, they say that in the future the earth’s climate is going to rise hugely over short periods of time, which will cause farming to be harder and consequently daily life and economy will be affected. Therefore, according to them a way to stop climate change, or at least to reduce it, is to stop the burning of fossil fuels. If this...
