...GS1140 Global Warming & the Ozone Layer Scientific studies have shown that tons of greenhouse gases being produced are destroying our planet. Greenhouse gases are constantly rising into earth’s atmosphere and destroying the ozone layer causing global warming. The rise of the temperature on earth puts vegetation, marine life, and human life in serious danger. Generally, holes in the ozone layer are the cause of global warming which has catastrophic effects on our planet. The ozone is in two areas of earth’s atmosphere, the troposphere and the stratosphere. The role of the ozone layer is to absorb most of the UV radiation from reaching the earth’s surface that comes from the sun. There are tons of greenhouse gases produced every year making holes in earth’s ozone layer, which cause harm to all life forms on earth. There are 2.5 billion tons of carbon dioxide pollution produced by power plants in the United States alone that are being released into the atmosphere destroying our ozone layer which blocks UV radiation from the sun. These UV radiation are harmful to human life, causing increased health issues such as, more skin problems, severe eye conditions and weakening of the immune system. Similar health effects are found in domestic and wild animals also. These effects are also dangerous for marine life because the increase in UV radiation causes damage to marine plant life and fish. The UV radiation affects many materials we use on a daily basis, such as fabrics...

...Between Global Warming and the Hole In The Ozone Global warming and the hole in the ozone layer are two topics that are frequently debated in the scientific community. After researching the two phenomena I feel that they are both very closely related, but I do not feel that one is the main cause for the other or that they share the same main cause. As far as the two producing the same effect, I do believe there may be some credibility in that theory. The hole in the ozone layer is caused mainly by the use of chlorofluorocarbons, or CFCs, which are most prominently found in aerosol based products, and halon which was produced mainly for use in fire extinguishers up until 1994. The two chemicals in CFCs that are most detrimental to the ozone layer are chlorine and bromine. Although the chemicals in CFCs are considered to be potent greenhouse gasses, they are not found in the atmosphere in a high enough concentration to be considered a main cause of the hole in the ozone layer. (Lindsey, 2010) Halon was produced for use in fire extinguishers until 1994 when the Clean Air Act banned the production of new halon. It was banned because there was no cost effective way to safely and effectively dispose of it and it was also proven to be harmful to the ozone layer. Halon is still used in fire extinguishers today, but all halon based extinguishers are now produced with 100% recycled halon. (CleanAgents, Inc. 2015) I do not feel that the hole in the ozone layer is the cause of global warming...

...The ozone hole is a man-made hole in the ozone layer above the South Pole during the Southern Hemisphere’s spring. The ozone layer, which lies high up in the atmosphere, shields us from harmful ultraviolet (UV) rays that come from the sun. Unfortunately we punched a hole in it, through the use of gases like chlorofluorocarbons (CFCs) in spray cans and refrigerants, which break down ozone molecules in the upper atmosphere. While some of the sun’s UV rays slip through the hole, they account for less than one percent of the sun’s energy. So these UV rays cannot explain the global warming of the planet. The sun's output of UVB does not change; rather, less ozone means less protection, and hence more UVB reaches the Earth. Studies have shown that in the Antarctic, the amount of UVB measured at the surface can double during the annual ozone hole. The Earth's ozone layer protects all life from the sun's harmful radiation. Less protection from ultraviolet light will, over time, lead to higher skin cancer and cataract rates and crop damage. “Global warming” refers to the long-term warming of the planet. Global temperature shows a well-documented rise since the early 20th century and most notably since the late 1970s. Worldwide, since 1880 the average surface temperature has gone up by about 0.8 °C (1.4 °F), relative to the mid-20th-century baseline (of 1951-1980).

...Global Warming, aside from pollution is one of the populations biggest concerns. Global Warming is caused by the Greenhouse effect. As mater of fact there are four steps in the Greenhouse effect. The first one is Sunlight radiates from the sun, through space, to Earth/-Es atmosphere. Number two is the sunlight enters the atmosphere and hits Earth. A small portion of it turns into heat energy in the form of infrared light. The heat gets absorbed by surrounding air and land, which in turn makes it warm. Number three infrared rays that are remitted, into the atmosphere are trapped by greenhouse gases. Number four the gas then absorbs the light and is remitted back to the Earth/-Es surface and warms it even more. Some of the naturally occurring greenhouse gases are Methane and carbon dioxide. This is the way the Earth keeps itself warm enough for mammals to live on it. The only problem with this is that humans enhance the process even more. Over the One Hundred and fifty years the emissions of greenhouse gases have been increasing due to the increase in technology that humans have developed (example, factories, Automobiles). These human- induced gases include carbon dioxide, methane, nitrous oxide, and ozone depleting substances such as CFCs, also known as Chlorofluorocarbons, hydro fluorocarbons, and per fluorocarbons, These gases are generated a number of human activities such as fossil fuel combustion, waste disposal in landfills, the use of refrigerator, numerous agricultural...

...2 Research Paper 1: Global Warming During the last fifty years, two environmental issues have received significant attention: global warming and the hole in the ozone layer. As scientists have investigated these two environmental phenomena some have made some effort to show that these two effects are somehow related. In this research paper I will further elaborate on their relationship. Ozone high in the atmosphere absorbs ultraviolet radiation from the sun, thereby protecting living organisms below from this dangerous radiation. The term ‘ozone hole’ refers to recent depletion of this protective layer over Earth's Polar Regions. People, plants, and animals living under the ozone hole are harmed by the solar radiation now reaching the Earth's surface—where it causes health problems from eye damage to skin cancer. In the 1980s, scientists discovered that the ozone layer was thinning in the lower stratosphere, with particularly dramatic ozone loss known as the ozone hole in the Antarctic springtime. This is caused by increasing concentrations of ozone-depleting chemicals in the stratosphere that come from spray cans and refrigerants. These long-lived chlorofluorocarbons or CFCs (chemical compounds with chlorine and/or fluorine attached to carbon) remain in the atmosphere for decades to over a century depending on the CFC. At the poles CFCs attach to ice particles. When the sun comes out again in the polar spring, the ice particles melt, releasing the ozone-depleting molecules...

...Only Time Will Tell Global warming is a topic that is affecting our world today at an alarming rate. We are seeing drastic temperature increase, receding polar ice caps, depleting ozone layers and habitat destruction. These things are all major issues that have become increasingly important because of global warming and there are numbers to prove that this is not just a hoax like some people believe. Increasing levels of Carbon dioxide and other greenhouse gases present in the atmosphere are raising the average temperatures on earth. Receding polar ice caps and rising water levels are destroying habitats for many creatures like the polar bear and other Arctic animals, and even are going to begin to destroy our own communities and space for living because there will be less land. Deforestation is also crippling animal populations in the tropics and forests are being destroyed at an alarming rate. All of these things are major issues that fit into global warming and these things must change if we wish to not destroy this planet. One of the major causes of global warming is the emission of greenhouse gases. The main gas that is responsible for global warming is Carbon Dioxide (CO2). This gas is emitted from various things, mainly from the burning of fossil fuels, energy production and factories. It is because of the Industrial Revolution, the burning of fossil fuels became central to the drive of economies. Starting in England in the late 18th century, factories began...

...Ozone Layer Depletion: Effects and Causes of Ozone Depletion Ozone is a colorless gas found in the upper atmosphere of the Earth and formed by the action of ultraviolet radiation on oxygen. Ozone forms a layer in the stratosphere, which protects life on Earth from the harmful effects of ultraviolet radiation. Ads by Google Olay Total Effects 1 Bottle Fights 7 Signs of Ageing, Try Olay Total Effects Today! www.olay.in Today, one of the most discussed and serious environmental issues is the ozone layer depletion, the layer of gas that forms a protective covering in the Earth's upper atmosphere. Ozone is formed when oxygen molecules absorb ultraviolet photons and undergo a chemical reaction known as photo dissociation or photolysis, where a single molecule of oxygen breaks down to two oxygen atoms. The free oxygen atom (O), then combines with an oxygen molecule (O2) and forms a molecule of ozone (O3). The ozone molecules, in turn absorb ultraviolet rays between 310 to 200 nm wavelength and thereby prevent these harmful radiations from entering the Earth's atmosphere. In the process, ozone molecules split up into a molecule of oxygen and an oxygen atom. The oxygen atom (O) again combines with the oxygen molecule (O2) to regenerate an ozone (O3) molecule. Thus, the total amount of ozone is maintained by this continuous process of destruction and regeneration. Ozone layer depletion first captured the attention of the whole world in the later half of 1970 and since then, many discussions...

...TOPIC = 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...

...Ozone is a gas found in the upper atmosphere and at ground level of the Earth’s surface. Ozone will mainly be found in two regions of the Earth’s atmosphere closer to our Earth. About 10% of Ozone is found in the region that starts from ground level of the earth known as the troposphere. According to scientific research findings this region of the earth’s atmosphere (troposphere) contains ozone that could be either good or bad depending on how closer it is to the surface of the Earth. The principle of ozone to nearer earth is that ozone is ‘’good up high’’ and ‘’bad nearby’’. Most of the ozone, that is, about 90% is found in the next atmosphere called stratosphere which starts about 10 and 17 kilometres above the Earth’s surface and extending up to about 50 kilometres. Generally Ozone gas is beneficial to human and other life on earth. It is ‘’chemically reactive oxidizing agent that is used as an air purifier, a water steriliser, and a bleaching agent’’. The Ozone in the stratosphere region forms what is known as the Ozone layer. Chemically ozone gas with a formula (O3) is formed from molecular oxygen (O2) in the stratosphere at an attitude of about 25km by the action of ultraviolet frequency photons .The formula O3 for ozone gas means the ‘’ozone molecules consists of three actions of oxygen arranged in the shape of wide V’’ .Scientific research also indicate that the ‘’name ozone is derived from the Greek word ozein, which means to smell or reek’’.

...'progressive' activists used to refer to anticipated effects of Y2K as such that would result in the end of the world, as we know it. In her article Technomillennialism: A Subcultural Technomillennialism: A Subcultural Response to the Technological Threat of Y2K, Andrea Tapia states: "Predicted scenarios (on account of Y2K) ranged from a few days of inconvenience, similar to a bad snowstorm, to that of complete global shutdown and resulting chaos" (2003, 483). Yet, on January 1, 2000, it became clear to just about anyone that Y2K was nothing but a sham. As of today, public still remains unaware of what happened to the milliards of dollars, spent by Western governments to mitigate the expected effects of Y2K. A decade earlier, the anticipated 'end of the world' was being discussed within the context of thinning of ozone layer over Antarctica – thus, resulting in creation of 'ozone holes'. In its turn, the thinning of ozone layer was believed to have been caused by aerosol sprays as such that contain chemical ingredient freon. Within the matter of very short time, after the beginning of 'ozone scare', the freon-containing sprays were prohibiting worldwide. However, this resulted in allowing DuPont Corporation to double its already enormous profits, as the only patent-holder on producing substitutes of freon. In his article A Necessary Apocalypse, available on the website of American Thinker, John...

...The topic of Global Warming has been a main topic for discussion for many years now. Most people know that the question is whether global warming is a natural cycle or whether it is caused or triggered by human activity. Different scientists have different opinions on this topic and have gone to great lengths in trying to find the most accurate answer. Some say there is a natural cycle out there and that earth’s temperatures increase due to a natural path that is perfectly normal. The fact is that earth left the natural path a long time ago. The past few decades the increase in temperatures all over the world have been way off the charts from years past according to an article by Alex Morales. Temperatures have been skyrocketing and scientists have no other explanation other than to say that human activity is the main cause of climate change to this point. Humans are the main cause of global warming and climate change. It really isn’t hard to see, yet most scientists won’t totally agree on this answer proven many times over. Humans always use nasty chemicals and gases in their basic everyday lives. The main gas is carbon dioxide that is released when humans drive their cars. This was stated in the article, “Final Report: Humans caused global warming”, by David Biello. Anyone can see that there is being a lot of this gas being released up into our atmosphere. This is in turn, is heating the planet at a much quicker rate than normally and making our temperatures...

...Global Warming During the last 50 years, two environmental issues have received significant attention—global warming and the hole in the ozone layer. As scientists have investigated these two environmental phenomena, some have made some effort to show that these two effects are somehow related. The rate at which global warming is occurring is a controversial subject among scientists. Because scientists have been studying the earth’s weather patterns for only the last century or two, it is difficult to make an accurate comparison of the recent weather data to the overall weather patterns of a planet that has existed for millions of years. Consequently, it is hard to know whether rising temperatures are a cyclical phenomenon or a trend that could have devastating effects on our planet. Very simply, global warming may be thought of as excess heat being trapped near the surface of the earth. Think about how hot a car becomes while parked in the sun on a summer day. The inside of the car is hotter than the surrounding air because the glass of the windshield allows the electromagnetic waves from the sun to pass into the car but does not allow the resultant heat to pass back out. In a similar manner, the burning of fossil fuels (coal, oil, gas, etc.) produces a layer of gases (commonly referred to as the greenhouse gases) that acts like the windshield of a car. This layer of gases allows the electromagnetic waves from the sun to pass through but does not allow the heat from...

...that the Environmental Protection Agency must regulate the carbon dioxide produced from cars and trucks in the United States. She goes on to say that, “[t]he climatic changes caused by the Global Warming are due to greenhouse gases and the responsibility of EPA is to regulate pollutants under the Clean Air Act” (Marris). This article provides support and evidence to show the serious effect car emission has on the earth. It is evident that car emission is the leading cause of global warming, a problem that can be addressed through being responsible. Although global warming is a highly disputed topic, certain pieces of hard evidence make the problem difficult to ignore. In 2000, more than three hundred NASA scientists published a report: NASA scientists directly correlate global warming with the cooling stratosphere and the depletion of the ozone. Global warming does not necessarily mean only warmer temperatures. The stratosphere is sensitive to temperature and the atmosphere tends to migrate due to variations. Areas with an active stratosphere will experience warmer temperatures as areas with an inactive stratosphere will be cooler. The world on a whole, US being only 2%, has experienced nine of the hottest years ever in just the last ten years (2000). Every morsel of proof that global warming is real can be traced back to car emission as its...

...Ozone depletion is a man made phenomena which industries release CFC (chlorofluorocarbons), rising up to the upper atmosphere exposing to high energy UV radiation from the Sun. Even though that CFC has low reactivity, flammability and toxicity, it remains inert in the troposphere as they disseminate among the stratosphere whereas the UV rays strikes the CFCs molecules and releases chlorine. The chemical reacts with ozone (O3/oxygen), a natural combination of O2 (oxygen) molecules and free oxygen atoms (O1) splitted by O2, by striking an ozone (O3) it leaves chlorine monoxide and an oxygen molecule, resulting in a loss of oxygen. This situation brings unfavorable results and consequences on living beings. It may cause human skin cancer and cataracts, affecting a plant’s formation, developmental process and nutrients absorbing; also implicating on their predators. Like plants, it is also a threat to the growth of marine and water ecosystems, and it affects the natural balance of gases, which, considered as biogeochemical cycles. The ozone layer can only be recovered by its own as we prevent releasing chlorine, such as replacing chlorofluorocarbon with chemicals with alike properties. This...
