Environmental Crisis and orbicular Warming EssayThe world and man resistant atomic number 18 facing assorted critical publishings and problems which we inevitably have to deal with. These concerns have great impact to our lives. quotidian people have to remind themselves of these various perils to their existence. The media to explicateher with different organizations answer us to become to a great extent aware of the problems currently on our midst. people may not find it an alarming and serious solvent since the danger at the present time is negligible but sooner or later we give come to realize that we really are into serious danger. world(a) issues are international concerns. It is felt nearly the world not just on a particular location. It is a world wide issue that needs to be address. in that respect are many types and cast of characterss of current globular issues that the world has to face. on that point is the frugal crisis felt all over the world. Vari ous health issues that came out as much people get vulnerable to cancer and other forms of illnesses. There is terrorism which is a crisis in peace and order and security. There is likewise issue on moral degradation of the society. Lastly is the global thawing or global climatic remove.Even though some believe global warming to be a hoax, yucky abide repercussions and environmental crisis prove the opposite. This global warming is an alarming environmental problem on a global scale. Some people still have doubts if the global warming issue is real or is just an imaginary anxiety fabricated by scientist who has predicted it as a serious problem in the near future. There was hundreds of information released al some the onset of global warming. Many people have do research and studies to investigate these phenomena.Documentaries are produce to open the minds and inform the public regarding the new findings regarding the problem. A individualised observation on our environmen t and a closer study lead help one to check and learn to a greater extent about the development regarding the current issue on global warming. Big scenery of the Environmental Crisis Global warming, what does it really mean? What causes global warming? What factors hold to this problem? And what are the effects of global warming? All of these are the questions frequently asked regarding this global environmental issue.Global warming is normally known as the warming of the planet cause by the greenhouse gases that trapped the heat. Global warming is similarly known as global climatic change or global climatic disruption. Global warming resulted from the increase in heat-trapping gases in the air that causes the amplified hydrological cycle resulting in increased precipitation and implosion therapy in some regions and more severe aridity in other areas. (Woods Hole Research Center, 2008) The idiomatic expression climatic change is preferred recently to be use than global war ming because it helps convey that there are other changes aside from rising temperatures.Global warming involves the average increase in temperature of the atmosphere near the res publicas surface and in the troposphere, which can contribute in global humour patterns. Global warming and climatic change can be caused by a variety of factors, twain natural and human-induced. (Environmental Protection Agency, 2008) Ozone layer depletion is oftentimes confused with global warming. Climate change and ozone depletion are different from one another but interrelated issues. Ozone depletion is not the principal cause of climate change and climate change is not the principal cause of ozone depletion.However, ozone depleting gases- such as chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) and halons are greenhouse gases that do contribute to climate change. Ozone itself is a greenhouse gas that has effect on climate. In addition, certain changes in undercoats climate could pr esume the future condition of the ozone layer. For example, low temperature and strong polar winds both affect the extent and severity of winter polar ozone depletion. (EPA, 2008) The greenhouse effect is a natural phenomenon that helps regulate the lands temperature. Greenhouse gases (e. g., carbon dioxide, methane, nitrous oxide, chlorofluorocarbons) act like insulating blanket, trapping solar vigor that would otherwise escape into space. Without this natural greenhouse effect temperatures would be about 60oF lower than they are now and feeling as we all know it today would not be possible. However human activities, primarily the earnest of fossil fuels and clearing of forest and industrialization have enhance the natural greenhouse effect, causing the earths average temperature to rise. (EPA, 2008) The greenhouse effect was first describes in theoretical terms by a Swedish researcher, Svante Arrhenius, in the late 1800s.However it wasnt until the following century that Arrhe nius theory was not sparkler. In the 1930s, scientist accomplished that parts of the globe had warmed during the previous half-century. Then in early 1960s scientist discovered that the train of carbon dioxide in the atmosphere was rising. Researchers began to take interest and found a strong relationship in between the increase carbon dioxide and average global temperature. (EPA, 2008) Human-induced global climatic change is under way. The IPCC (Intergovernmental beautify on Climate Change) concluded that global mean surface air temperature has increased between about 0.5 and 1. 1 degrees Fahrenheit in the last 100 years and anticipates a further go along rise of 1. 8 to 6. 3 degrees Fahrenheit during the next century. Sea-level has risen on average 4-10 inches during the recent 100 years and is expected to rise another 6 inches to 3 feet by 2100. (WHRC, 2008) Charts and graphs showed alarming trends. atmospheric carbon dioxide concentration has increase steadily over the pa st few years. The increase in the temperature is observed as well as the increase of the sea level. More disturbances in climate patterns have been greater in the previous years.These are environmental changes brought by this problem on global warming. Being environmentally Conscious What are the ways to be conscious and aware of our impact on earth? People have to find ways or alternative get-up-and-go resources. In the US for example the button related activities account for over three quarters of human generated greenhouse emission, mostly in the form of carbon dioxide emissions from burning fossil fuels. Enhanced energy efficiency is found to be one of the cheapest, most effective and safest ways to reduce global warming.Buildings should pract drinking glass energy efficiency. Cutting the fuel cost on the road by effective gas mileage depart also help. Making home appliances more energy efficient will significantly lessen energy consumption. (wecansolveit. org, 2008) Adoption of renewable resources will help break the addiction to fossil fuels like coal and oil by switching to renewable energy. These overwhelm wind power, solar thermal, solar photovoltaics and geothermal power. (wecansolveit. org, 2008) Campaigns like Zero bollix up for Zero Warming should also be supported.Landfills were found to be the largest source of methane (CH4) in the US, a global warming gas 23 times more powerful than CO2. Toxic dumps, landfills and incinerators must not be tolerated. People should learn to cycle and avoid littering. We can also use cloth bags as shopping bags to minimize waste. We need to prove green homes and businesses therefore taking monitor of our own carbon footprint. (Global Day Action, 2007) The Outcome If We Dont Change Things Who and What Will Be Affected? Severe weather changes will be the outcome if global warming will not be resolve early.These entangles climatic change that will contribute to more destructive hurricanes and floods like Katr ina, Gustav and Ike that cost millions of damages to property and life. Severe droughts will be experience in other parts of the world, deadly heat waves, wildfires and ocean temperatures rising. It will also affect the precipitation by increasing about 5 percent in atmospheric water vapor over the oceans increasing the risk of heavy rain and snow events. Scientist also predicted that the global average sea level will rise by 7 to 24 inches by 2100 due to thermal expansion alone.Arctics average temperature increases are nearly twice that of the rest of the world. The arctic sea ice could virtually evaporate during the summer of 2020. Melting of permafrost will continue. This permafrost is ice that has permanently frozen into the ground. The permafrost traps methane and when the melting continues it will release more of it into the atmosphere. Melting due to climate change is expected to reduce the size and extent of the polar ice caps, even taking to account the potential of more s now and ice accumulation atop the ice sheets due to increased precipitation.Temperature changes in the Arctic Circle also cause polar bears to die. Also temperatures on a lower floor oceans caused destruction of coral reefs. Ecosystems will also be affected because of floods and drought could lead to the risk of quenching for some animals and plant species. Agriculture and farming will also be affected due to weather extremes. Human health will also be greatly affected which will result in increases cases of malaria and dengue outbreak. Heat-related illness and cold related illness will increase. (EPA, 2008).Sandra Steingraber the author of Living Downstream also mentioned that the increase in cancer cases is attributed to environmental influences. The US Climate Policy The United States Federal establishment has established a comprehensive policy to address climate change. This policy has three basic objectives that is to say slowing the growth of emissions, strengthening scienc e, technology and institutions and enhancing international cooperation. The federal government is implementing this policy through self-imposed and incentive based programs and has established major government-wide programs to advance climate technologies and improve climate science.(EPA, 2008) Some of these policies include the national goal to reduce emissions intensity, current and near tem greenhouse gas reduction initiatives, climate change technology program, climate change science program and international cooperation like the IPCC and the Asia Pacific Partnership on Ocean Development and Climate. Action on global warming by cities and local anaesthetic government includes structure codes, zoning, transportation systems and electricity production campaigns.These include local regulation requiring newly constructed homes to be more energy efficient, a city or local subsidy to encourage homeowners to install electricity generating solar panels, local regulations requiring el ectric utilities to produce at least 20% of their electricity from wind, solar, or other renewable energy sources. , changing the citys or towns zoning rules to require neighborhoods have a mix of housing, offices, industry, schools and stores close together to encourage walking and decrease the need for using cars among other regulations or local climate change policies. (American jump for Local Action on Global Warming)Conclusion Global warming is a real problem of our times. Some are skeptics and believe it is just a kind of hysteria by some scientists. Even if Al Gore emphasized global warming in his documentary film The Inconvenient Truth many still have doubts if it is real. Nature or what we forebode mother earth like humans need to be taken care of. It is our responsibility to negociate our earths natural resources and to preserve our planet making it a livable place. If people will continue to abuse the environment and become careless in throwing toxic waste and emitting toxic gases our planet will eventually come to destruction someday.The predictions may not be far from real for us at the moment but it doesnt mean we should neglect our responsibility in protecting our environment. There is still time for people to reduce the outcome of this event. People should start thinking seriously on how they can contribute in solving and altering the increasing scenario of global warming.ReferenceAmerican Support for Local Action on Global Warming (2008) Yale School of Forestry And Environmental Studies.
