...GLOBAL WARMING MAN-MADE 8/8/2012 Global Warming Fact or Fiction I. Theory of global warming A. Is man-made global warming credible or not credible? 1) Evidence 2) Causes and effects Global warming is a term used to describe an increase over time of the average temperature of the earth’s atmosphere and oceans. Over time it has been arguments of humans are contributing to global warming. It has also been a question if global warming is causing our earth’s climate to change. Use of the term “global warming” generally implies a human influence. A more neutral term which is climate change is used for a change in climate with no human influence an example could be the “ice age.” Natural causes are causes created by nature such as a release of methane gas from arctic tundra and the wetlands. Methane is a greenhouse gas and is known to trap heat in the earth’s atmosphere. Another natural cause is that the earth goes through a cycle of climate change and usually lasts about 40,000 years. Man-made causes are said to do the most damage. There are many man-made causes pollution being the largest man-made problem. Burning fossil fuels is one thing that causes pollution, they are fuels made of organic matter such as coal or oil. When these fossil fuels are burned they give off a green house gas called CO2. Mining coal and oil also allows methane to escape, the methane is naturally in the ground and while mining coal or...

...DEBUNKING THE GLOBAL WARMING THEORY Name of Author Institutional Affiliation There has been a growing concern over the issue of global warming over the years. A vast number of global warming skeptics, politicians, and groups of scientists such as those that constitute the IPCC believe that climate change is adversely influenced by human activities that constantly raise CO2 levels. However, new studies reveal that there is little evidence to support the popular theory that global warming is directly influenced by man’s activities, and it is this that discredits the baseless global warming theory. First, there are no real scientific proofs that support the global warming theory. Contrary, most of the observations over the past 30 years reveal that human activities are not a contributing factor to the rise in temperatures. In fact, most of these temperature changes are natural. Fossil fuels, on the other hand, cannot be labeled as the main cause of global warming despite their contribution to CO2 levels. The IPCC can be disputed for its scientific consensus report because most of its scientists lack scientific qualifications, and there are scientists in the same panel that object sections of the IPCC report that relates CO2 emissions to the increase in global temperatures. It is also worth noting that some corporations stand to benefit from the global warming scare, and this may be a reason why the theory still exists. Ultimately, it is absurd to blame a single gas for the...

...WHAT IS GLOBAL WARMING? Global warming is defined as the increase of the average temperature on EARTH. As the earth is getting hotter, disasters like hurricanes, droughts and floods are getting more frequent. Over the last 100 years, the average temperature of the air near the Earth´s surface has risen a little less than 1° Celsius (0.74 ± 0.18°C, or 1.3 ± 0.32° Fahrenheit). Which does not seem that much? It is responsible for the conspicuous increase in storms, floods and raging forest fires we have seen in the last ten years. Their data show that an increase of one degree Celsius makes the Earth warmer now than it has been for at least a thousand years. Out of the 20 warmest years on record, 19 have occurred since 1980. The three hottest years ever observed have all occurred in the last eight years. [pic] WHAT IS THE GREENHOUSE EFFECT? Seen from space, our atmosphere is but a tiny layer of gas around a huge bulky planet. But it is the gaseous outer ring and it is misleadingly called greenhouse effect that makes life on EARTH possible-and that could destroy life as we know it. The sun is the Earth’s primary energy source, a burning star so hot that we can feel its heat from over 150 million kilometers away. Its rays enter our atmosphere and shower upon on our planet. About one third of this solar energy is reflected back into the universe by shimmering glaciers, water and other bright surfaces. Two thirds, however, are absorbed by...

...Climate Change is a Natural Cycle: Global Warming is a Hype Terra Nova is a new American TV series on the Fox network, which airs on Mondays and has caught the attention of a wide audience for its science fiction suspense. The show is intriguing because it relates to a huge debate going on right now amongst scientist, politicians and environmentalist; Global Warming. Is it real and if so, are humans the cause. In Terra Nova it is year 2149 and Earth is being destroyed to extinction due to air quality and overpopulation therefore, it has become impossible for humanity to survive and almost no vegetation exists. This leads humans to scramble and figure out a way to survive by trying to go back in time and not make the same mistakes. Although, Terra Nova is just a show many believe the concept is true even though there is no conclusive proof that humans are the cause of global warming. Scientist on both sides of the debate, agree that global warming exist but the argument is whether or not humans are the cause by the burning of fossil fuels and if it will destroy Earth. There are many factors that contribute to the warming of Earth, but man-made global warming is just a theory that has been hyped up because scientist cannot disprove that climate change is a natural cycle that has been happening for thousands of years. It is clear that the man-made global warming campaign has exploded and many people are benefitting from it regardless of how little scientific data there is to...

...Causes and effects of Global Warming DEFINITION =Global warming refers to the increase in the average temperature of global surface air and oceans and to continuing increases in those temperatures. Another term for "global warming" is "climate change." Global warming is primarily a problem of too much carbon dioxide in the atmosphere which acts as a blanket, trapping heat and warming the planet. CAUSES -Natural causes are causes created by nature. One natural cause is a release of methane gas from arctic tundra and wetlands. Methane is a greenhouse gas. A greenhouse gas is a gas that traps heat in the earth's atmosphere. The build-up of greenhouse gases in the atmosphere alters the radioactive balance of the atmosphere. The net effect is to warm the Earth's surface and the lower atmosphere because greenhouse gases absorb some of the Earth’s outgoing heat radiation and reradiate it back towards the surface. -Ozone depletion is also one the causes of global warming. Plummeting ozone levels in the stratosphere over Antarctica during September and October are the result of complex chemical processes. The return of the Sun at the end of winter triggers photochemical reactions that lead to the destruction of ozone in the stratosphere. There are some natural means that effect ozone like volcano eruptions, and drastic changes in weather problems. -Man-made causes probably do the most damage. There are many man-made causes. Pollution is one of the biggest man-made problems. Pollution...

...Global Warming The major threat of today’s world is global warming. Due to various reasons global warming turns out to be a serious issue in the last few years. Today people believe in global warming while this concept was not so much believed and people interpreted in some other meanings what was happening in the past. Global warming is amplification in the temperature of earth because of industrial pollution, fossil fuels, and agricultural practices caused by human being, other and natural gas emissions. Because of this greenhouse gases are released in large quantity. Solar radiations of short wave type go down under the earth and increase its surface temperature, while infrared radiations of long wave type that is released by earth are absorbed and then gases re-emit these waves again. And this climax of greenhouse gases is the cause of change in our earth atmosphere. Serious problems can arise when large quantity of these greenhouse gases buildup in our atmosphere because these gases improved the heat trapping ability of earth. Major Causes of Global Warming The causes of global warming are divided into two categories mentioned in the following: 1. Natural Causes: The causes created by nature are natural causes. One natural cause is an emission of methane gas from wetlands and frosty tundra. Methane gas is called a greenhouse gas that traps heat in the atmosphere of earth. The earth cycle of atmosphere changer is another natural cause. And this atmosphere cycle approximately...

...Global Warming “The Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 7,000 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.” (NASA.GOV) Going through the history in our planet’s timeline, global warming seems to be an issue that is rising as time moves forward. People are more focused on materialistic things and are less worried with the planet. Not thinking about the future but only about what we are living in the present, we as human beings are considered selfish. Unfortunately, the imbalance that we are creating between our lives and earth is already showing the catastrophic signs in the form of cyclones, flood, tsunami, etc. If the imbalance continues to increase, one day the conditions will put a question mark on the existence of this planet. Several current trends clearly show that global warming is directly impacting the sea levels, the melting of ice caps and significant worldwide climate changes. “When it comes to connecting the dots between climate change, extreme weather and health, the lines are clear.” (NRDC.ORG) In short, global warming represents a fundamental threat to all living things on earth. We need to start to think not only about ourselves...

... Group 5 Global Warming Introduction Global warming begins when sunlight reaches Earth. The clouds, atmospheric particles, reflective ground surfaces and ocean surface then reflected about 30 percent of it back into space, while the remaining is absorbed by oceans, lands and air. This in turn heats the planet’s surface and atmosphere, making life possible. As Earth warmed up, this solar energy is radiated by thermal radiation or infrared heat, travelling directly out to space, thus cooling the Earth. However, some of the outgoing radiation is re-absorbed by carbon dioxide, water vapor and other gases in the atmosphere and is radiated back to Earth’s surface; these gases are known as greenhouse gases due to their heat-trapping capacity. This re-absorption process is naturally good; the Earth’s average surface temperature would be very cold if not for the greenhouse gases. Causes of Global Warming Global Warming is caused by many things. The causes are split up into two groups, man-made or anthropogenic causes, and natural causes. Natural Causes Natural causes are causes created by nature. One natural cause is a release of methane gas from arctic tundra and wetlands. Methane is a greenhouse gas. A greenhouse gas is a gas that traps heat in the earth's atmosphere. Another natural cause is that the earth goes through a cycle of climate change. This climate change usually lasts about 40,000 years. Man-made Causes Man-made causes probably do the most...

...Survey of Science and Technology in Society Global Warming: Crisis or Conspiracy What is global warming? Or climate change for that matter? How did it start? How will it continue? What will happen to humanity? Will it one day be gone, due to our own ignorance? These are some of the questions raised by a percentage of the society who believe in the facts and evidences presented by the scientists and environmentalists. While the other part of the society seem divided over this issue, these groups of skeptic individuals, strongly deny the theory that global warming is a big issue and require urgent attention. Their beliefs are based on scientific facts too. So what’s right and who’s wrong? The debate doesn’t seem to stop. To begin with, Global warming is the continuing rise in the average temperature of the earth’s climate system, forcing it to change. Though change in climate is nothing new for the earth, according to the evidence and facts provided by the article “Global Climate Change” posted in NASA’s official website, the Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives. The current warming trend, however, is of particular significance because most of it is very likely human-induced and proceeding at a rate that is unprecedented in...

BUSN300-1102B-13 What is Global Warming? Global warming is when the earth temperature rises. This typically occur when the greenhouse gases which are carbon dioxide, water vapor, nitrous oxide, and methane trap heat and light from the sun in the earths atmosphere, in result increasing the temperature. These gases can have an affect on humans, animals, and plants when these life forms come in contact with this change the end result can be death. Some of the facts about global warming are the gradual increase in temperature. From a personal stand point as a child I can remember staying outside everyday and playing all summer in the hot sun. Yes it was hot back then especially being from the south but it seems there is no comparison...

...Global Warming And Its Effects On The Coastal Areas of Bangladesh [pic] [pic][pic] GLOBAL WARMING: Global Warming is the rise in the average temperature of the Earth’s atmosphere, including the surface air and oceans. In simple words global warming is when the Earth heats up. It is caused mainly due to increasing concentration of greenhouse gases in the Earth’s atmosphere. The greenhouse gases, include carbon dioxide, nitrous oxide, methane, water vapor, traps heat and light in the Earth’s atmosphere, which increases the temperature. Today global warming is considered as one of the major environmental issues, which threatens to disrupt the basic balance of the environment and cause large scale destruction. The Greenhouse Effect: [pic] There are certain gases that raise the temperature by trapping the sun’s heat and energy. The Earth’s average temperature would have been about 60Error! Hyperlink reference not valid. colder if it weren’t for these gases. These gases are referred to as “greenhouse effect” because of the way they help to keep the Earth warm. The greenhouse effect makes the Earth suitable for all living things. The Earth might have been freezing or it might also have been burning hot if the greenhouse effect did not occur. However, the presence of too many such gases can cause the Earth to get unusually warmer. The plants would not be able to take such heat and eventually they would have died. The scarcity of plants would cause animals to die...

...atmosphere doesn't act as a single unit; it is made up of hundreds of different layers. Some of the energy released from Earth is stopped in each of these layers. The energy is then re-emitted in a random direction, but on average the energy is moving either "up" or "down." The atmospheres get thinner as altitude increases, so eventually the radiation will reach a layer high enough and thin enough to escape to space. If you increase the concentrations of a greenhouse gas in the atmosphere, the thin upper layers will become denser. The place where the majority of the energy finally escapes moves higher, these higher levels are much colder and so they do not radiate heat very well. The rate that radiation escapes to space is lower, and the planet will take in more than it radiates. As the higher levels emit some of the excess radiation downwards, the lower levels will warm all the way down to the surface. The imbalance will remain until the higher levels get hot enough to radiate as much energy back out as the planet is receiving. Though all natural processes, they are not always helpful. On the other side of the spectrum, we as humans are not always helpful to the processes. Because of this, we find ourselves at a time of question. What are we doing to our planet and how will it affect us? Many are attempting to take action now, others try to not believe. Eventually, however, we are all going to see what we have truly been doing. Global warming is possibly the most debated topic today...

Natural disasters have increased due to the climate change. Christian’s responsibility for creation is to restore its landscape, agriculture, animal life, and human livelihood. Christians have a responsibility to preserve creation by recycling, proper disposal of hazardous waste, and create protection agencies for wild life. Christians have a responsibility to take care of creation, restore, preserve, and protect creation in all aspects which God has commanded man to do. God’s involvement in creation is understood for Christians in the Bible starting at Genesis 1. The Bible shows at the beginning God’s hand is expressed in all aspects of creation. The first day of creation God made space, time, earth, and light. On the second day, God created the atmosphere of the earth which then making it possible for life on earth. The third day, God made dry land and called it “earth.” God names the water “sea.” God also created the vegetation, plants that produced seeds for reproduction, fruit with seeds in the fruit, and trees. The fourth day, God created the Sun, moon, and stars. The purpose was to be able to tell signs, seasons, days and years. The fifth day, God created the Sea and flying animals on earth also including dinosaurs. The Sixth day, God created the all forms of land animals and man. God created man...

...Global warming means the rise in the mean global temperature to a level which affects the life-forms on the earth surface. The factors responsible for this warming may be both natural and man made. Warming of the globe due to natural factors is not an unusual phenomenon. The earth's climate is variable. For example, about 18,000 years ago, the earth was about 5°C cooler than it is today. That was the last glacial period on the earth. There after, the global temperature began to rise. The earth is kept warm due to what is known as the green house effect. Without it the earth would be a frozen waste land. The short wave lengths or ultraviolate radiation coming from the sun penetrates the atmosphere and is absorbed by the earth. This observed energy is also radiated back to space at infra-red wave lengths. The earth atmosphere contains gases which trap some of the outgoing radiation and thereby warm the earth. These gases are known as green house gases. Wastes vapour, carbon dioxide, methane, ozone, nitrous cxide, CFCS and halons are prominent examples to maintain the global energy balances, both the atmosphere and the surface will warm until the outgoing energy equals the incoming energy. The increase in the quality of the greenhouse gases in the atmosphere can reinforce the greenhouse effect (increase in temperature of the earth) and lead to global warming. Carbon dioxide is the largest contributor to the global warming as it holds the largest share among the green...
