... Global warming is a threat to mankind and its existence; although we are yet to see or feel the effects. However, understanding the cause, and implementing measures to save the planet are of dire urgency otherwise, the impact will be imminent in the near future. In approximately 1,000 years ahead due to rapid growth in the world’s population, and Man’s ever-growing chemical technologies, the impact of global warming is predictable. Global warming can be defined as the gradual increase of the earth’s atmospheric temperature due to the release of carbon dioxide, methane gas, fossil fuels, and other toxic chemical emissions trapped in atmosphere that causes correspondence changes in climate. These changes are rapid in the global atmosphere over a relatively short period of time, and becoming more prevalent in the world presently. There are numerous records that show that our world as a whole is getting incredibly warmer, poor health conditions, strangulated economy, and environmental degradation. Some say the world will end in water due to melting ice, some say it will end in fire as a result of radiation. From my observation and understanding, I hold with those who favor fire. Global warming affects human health, the world economy, our environment, and the planet as a whole. Health is the general condition of body and mind (Dictionary.com). The environment plays a significant role to our health, and every...

...significant role in the country’s economy, contributing in 2000 about 2.9% of GDP, 10% of formal employment and 10% of the total value of exports. Agriculture as a percentage of GDP has decreased over past four decades, currently contributing around 2%. This implies that the economy is maturing, moving towards the 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...

...2014 Global Warming Global Warming is a serious situation. Its nothing to overlook. Our world is looking at detrimental effects in the future if Global Warming continues to increase. Effects like, Coastal Flooding, where glaciers are melting all over the world and ice shelves are breaking off of the Antarctic continent. Or effects like Extreme Weather, whereas warmer air masses can hold more moisture. that’s why we’ve been seeing more tornados, typhoons and hurricanes over the past few years. And the most predominant effect, Increased Drought and Famine, where although much of the impact from climate change and its effects on water is related to the increase in storms and coastal flooding described above, one thing a lot of people don’t realize is that there is an associated change in the distribution of water on the planet overall. Some areas get too much water, but some aren’t getting enough , leading to the increase of drought and famine. Scientist’s studies shows that Carbon Dioxide (CO2) is released into the atmosphere when we burn fossil fuels, oil, coal and gas, which traps heat and acts like a blanket to warm the planet. The more gas we emit into the air, the more heat is trapped, which means the earth gets hotter and hotter. The importance of this is crucial because the hotter the world gets, the faster the world dries up and soon we will be in the worst drought ever. There are many things that needs to be done on a government level to help fix Global Warming like...

...Axia College, University of Phoenix [COM 220- 08 March 2009] Have you ever watched a television program, or read an article about Global warming? A person would be hard pressed to find someone who hasn’t. The news is hard to ignore since the information that is given to us comes from scientists or experts in the field of global warming. We are continually bombarded with information that the Earth is experiencing a warming trend, and human activity is to blame. The pollution that man creates is adding to the earth’s greenhouse gases. The resulting affect of global warming is triggering warmer temperatures around the world, and ecosystems are taking the toll. One of the most publicized looming catastrophes is the plight of the polar bears. Once the glaciers are gone, the polar bear will be extinct in the wild. Although, scientists say it is caused by the pollution that humans are creating, global warming is a natural phenomenon. Snow capped mountains are a wondrous sight to behold, and can be found on every continent. But, these massive ice shelf’s have a purpose that many people take for granted. Many people do not realize that glaciers are responsible for part of the world’s water supply. Revkin (2003) states “The melting is likely to threaten water supplies in places like Peru and Nepal” (¶ 19). The result from the melting glaciers will raise water levels and potentially create devastating floods over time. The eventual outcome that these countries...

...| GLOBAL WARMING AXIA AT UNIVERSITY OF PHOENIX What exactly are the causes of global warming? Is there anything that can be done about it? These are the questions that have become the main focus of arguments and lectures around the world regarding global warming. Global warming is a major Atmospheric issue that has been damaging our precious environment for many years. In recent years the issue of global warming has become an increasingly popular matter among society. Both the causes and effects of global warming have been the topic of heated debate not only among scientists, but among politicians, businesses, and general members of society as well. Global warming is defined as a measurable increase in temperature of Earth’s atmosphere, oceans, and landmasses. Greenhouse gases have been pinpointed as the main cause of this increase in temperature. The burning of fossil fuels such as coal, oil, and natural gas have caused a thirty-five percent increase in carbon dioxide (a highly potent greenhouse gas) since the 1750’s (MSN Encarta, 2008). Since the Industrial revolution in the mid 1700’s there has been a significant increase in the production of greenhouse gases. Greenhouse gases such as water vapor and methane occur naturally in the environment. Other greenhouse gases, like hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride are created as a result of the industrial process which is used by humans (West, 2009). Greenhouse gases are the...

...Global Warming Cause and Mitigation Vanessa Gunnoe Week 9 assignment Professor Pavlov 06/07/2013 ------------------------------------------------- The role of anthropogenic climate changes is a climate change that refers to the production of greenhouse gases emitted by human activity. By examining the polar ice cores, scientists are convinced that human activity has increased the proportion of greenhouse gases in the atmosphere; The Earth has a natural greenhouse effect where certain gases (known as greenhouse gases) in the atmosphere allow the sunlight to enter but absorb the heat radiation. Because these gases absorb the heat, they average the surface temperature on Earth around 14°C. Without the natural greenhouse effect, the Earth’s average surface temperature would be around -19°C.which has skyrocketed over the past few hundred years. In other words this is anthropogenic climate change, and the significant increases in the atmosphere of these potent greenhouse gases are a result of human activity. The most potent of the greenhouse gases are carbon dioxide (CO2), methane (CH4) and nitrous oxide (N20). Alarmingly, these are a result of anthropogenic climate change, and the gases are at the highest levels for over 650,000 years. Since 1750, it is estimated that about two thirds of anthropogenic climate change CO2 emissions have come from fossil fuel burning (coal and petroleum) and about one third from land use change (mainly deforestation and agricultural).

Global warming has become a major problem as we move on to 21st century and beyond. Like the old say goes, prevention is better than cure. We have done enough damage, knowingly and unknowingly we have contributed to global warming. Our efforts and determined contribution to reduce global warming and spare the ecosystem to recover thereby cautiously working restore the balance of nature is very urgent. Pollution of the atmosphere has to be checked and anything related to the release of the greenhouse gases should be monitored. Deforestation should be stopped as it causes the concentration of carbon at a greater extent. It has been said that it takes roughly 19 trees to make one ton of paper and that the usage of one ton of recycled paper will save approximately 17 trees. The burning of wood should be reduced to a greater extent as it releases oxidizable carbon to the atmosphere whose presence in greater amount causes the elevation of temperature. LPG stoves can replace the fire wood burning. Bio...

...created mankind above all else and entrusted us with ruling over the land, seas, and skies, while caring for all living things. To understand our roles, we must understand the inherent responsibility of a ruler and a tenant. Merriam-Webster’s Dictionary (2014) defines a Ruler as someone responsible for commanding a certain area, group, or people; and a Tenant as “one who has the occupation or temporary possession of lands or tenements of another.” Not unlike a landlord as we know them today, if we fail to care for the property and lives God has entrusted us to keep, we will likely face permeant eviction. As Christians we should pride ourselves in caring for God’s creation, using each and every resource wisely, and not to meaninglessly waste, kill, poison, and destroy. Over the course of our existence, we have prospered from every intricate detail God has bestowed, and often times we have abused His generosity and trust; vulgarly displayed by Adam and Eve. In the book of Genesis (2:15, NIV) it states “The Lord God took the man and put him in the Garden of Eden to work it and take care of it.” God’s intent has remained the same as He wishes for us all to be stewards of His creation. Therefore Christians have a responsibility to preserve and restore the Earth, by reducing water usage and waste, proactively fighting against global warming, and protecting all of the earth’s inhabitants. Reducing Water Usage and Waste Water is the lifeblood of all mankind and without a clean and...

...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...

...Global Warming: Fact or Fiction Margaret A. Brown AIU Online Global warming, also known as the green house effect is a topic that has received much attention in recent years. There are many who believe the global warming is real and will cause the destruction of earth as we know it. There are also many who believe that although global warming is happening, it will not lead to the destruction of the earth, but may in fact help it. For centuries, the earth gases were in balance. Humans and animals produce these gases by burning food in our bodies with the oxygen we breathe. Trees and other plants reverse the process with photosynthesis, turning carbon dioxide back into oxygen and vegetation which is food for us and the animals (Global Warming: background, 2009 ). With the growth of the human population and activities, there is no way that plants and oceans can absorb the billions of tons of greenhouse gases produced by the earth each year.. Yes the earth is already showing many signs of worldwide climate change. The average temperatures have climbed 1.4 degrees Fahrenheit (0.8 degree Celsius) since 1880, with much of this in recent decades. The rate of warming is increasing. These last two decades of the 20th century is reported as the hottest in 400 years. The average temperatures in Alaska, western Canada, and eastern Russia have risen at twice the global average. Arctic ice is rapidly disappearing...

...Global Warming There is no denying fact that Global Warming is a major issue in post modern society. Global Warming is the increase of Earth's average surface temperature due to effect of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth. In this essay the reason and solutions will be discussed before coming to any conclusion. First and Foremost reason of this issue is the Developments of human civilization. Human invents many things to live his life better and comfortable. For that human bread use the fossil fuel for their transportation, factories and do deforestation for their urbanization. Man done many nuclear experiments for their researches. All these things create green house effect. Actually green house effect is caused by the role played, green house gasses such as Carbon dioxide, Methane and Nitrous oxide, these are major cause of Global Warming. On the other hand, we can say that, may be this is a major problem of the present era, but it does not mean that it is not curable thing. We should use natural resource of energy for transportation, factories and for other needs. The sources of natural energy are Solar Energy, Bio-Fuel, and Wind’s Power. For example Sun is the major source of free and eco-friendly energy and we are not using it for our development. It may reduce our problem of pollution. In addition we could use public...

...Global warming is largely attributed to human activities that emit greenhouse gases to the atmosphere rather than the natural causes. The greenhouse gases such as carbon dioxide are the main causes of global warming since presence in the atmosphere leads to absorption of heat energy from the sun rather than emitting it to the space (Silver 135). The issue of climate change is a global concern since affects all regions and not just the countries where there are huge emission of greenhouse gases. Despite this, the initiatives to control global warming mainly lie with the governments, environmental organizations, and industries whereas there is little input of the individuals. These agencies are characterized with deep information about the consequences of global warming that is linked to strong intervention practices adopted. There are numerous researches conducted on global warming and consequences whose discussions are embraced in government and environmental agencies. Greater success of intervention practices would be achieved through increased involvement of the people. Since the knowledge of global warming impacts is influential to the development of control measures, greater understanding of the impacts of global warming would be instrumental to attain increased involvement of individuals in intervention practices. Global warming causes extreme temperatures, which affect quality of life and could be unbearable to people and other living organisms in highly affected regions...

...compromised from excessive use of different chemicals? This is the question that has been the ground for major debate for many years, is our advancements causing global warming? When debating global warming the first thing to consider is what the cause of global warming is, and the answer to this basic question is greenhouse gases. Greenhouse gases are natural gases such as CO2, Nitrous Oxide or Methane and are created in one of two ways. The first way is, through natural cycles, for instance, CO2 is released through animal respiration or plant photosynthesis. The alternative greenhouse gas production comes from man’s use of different fuels and products; this can lead to anthropogenic climate changes. Anthropogenic Climate Changes are changes in the atmosphere brought on by human activity, and there is evidence of these kinds of changes all over. By studying the size of the polar ice caps we can see that they are shrinking and this may be due to a warmer atmosphere temperature brought on by none other than an anthropogenic climate change. An IPCC report from 2007 showing levels of some of the greenhouse gases also shows that the levels of greenhouse gases in the earth’s atmosphere has skyrocketed since the post-industrial era, this can only be attributed to man-made machines that have come to rise. So how does human activity attribute to the climate rise? Greenhouse gases are natural occurring gases that hold in some of the heat energy that comes from the sun and bounce off...

...Not long ago, few people thought much about the role carbon dioxide plays in Earth's atmosphere. Today, with each new mention of melting ice caps, rising sea levels, and higher than average temperatures, we hear more than ever about a connection between human activities, carbon dioxide, and global warming. What is the connection between this gas and a potential global catastrophe? Before looking at carbon dioxide's role in global warming, it is important to recognize the role this naturally occurring gas plays in maintaining our planet's temperature. Earth's relatively warm surface temperature is the result of an atmospheric process called the greenhouse effect. Among the molecules that blanket our planet are some gases that absorb heat. They act much like the glass of a greenhouse, letting sunlight in while preventing heat from escaping. For this reason they are called greenhouse gases. The most important naturally occurring greenhouse gases are water vapor (H2O), carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). Carbon dioxide is the greenhouse gas climate experts are most concerned about because the increase in human-related CO2 emissions since the industrial revolution is now linked to the current global warming trend. As this resource illustrates, carbon cycles through the environment and often changes its molecular form. Some types of carbon molecules remain unchanged, or sequestered, in the environment for long periods of time. The diagram shows these...
