I will be covering the aspects, causes and effects of Global Warming. There are many definitions of Global Warming. One of these is that “ Global warming refers to an average increase in the Earth's temperature, which in turn causes changes in climate.”(EPA) The temperature increase can lead to changes in the average rainfall results, the sea levels can rise, and it may have many impacts on wildlife, plants of humans. The Global Warming is mainly cause by humans. The Green House Effects is one of the main causes of this warming.
EAP VI/A R/W YUCHENG WAN 11/27/12 Is Global Warming Manmade? Abstract Global warming is caused by numerous activities such as driving, taking airplanes, generating electricity, displaying fireworks, using air conditioning, developing industry and logging because those activities emit so much carbon dioxide that global temperatures rise up. Trees store CO2 in the forest system, so if forests are damaged, much CO2 will be released, which will increase the global temperatures. As this paper illustrates, natural climate cycles have already changed from warm to cool, so global warming is not because of natural factors. The solutions for global warming may include improving the efficiency of energy, protecting forests, producing more energy from renewable sources, generating electricity by wind, traveling in more fuel-efficiently vehicles, riding bicycles and using more efficient electrical appliances.
Natural Causes of Climate Change The earth’s climate is influenced and changed through natural causes like volcanic eruptions, ocean current, the earth’s orbital changes and solar variations. Volcanic eruptions - When a volcano erupts it throws out large volumes of sulphur dioxide (SO2), water vapour, dust, and ash into the atmosphere. Large volumes of gases and ash can influence climatic patterns for years by increasing planetary reflectivity causing atmospheric cooling. Tiny particles called aerosols are produced by volcanoes. Because they reflect solar energy back into space they have a cooling effect on the world.
Owing to the development of industry and the use of fossil fuels, the amount of carbon dioxide in the earth’s atmosphere has produced and the average global temperature seems to have risen. What’s more, deforestation can affect climate changes. The growing of trees and plants can absorb carbon dioxide from the atmosphere because of photosynthesis, however, deforestation lead to carbon dioxide emissions. Both of these can lead to global warming of the atmosphere. The report (UNEPWMO, 2004, P10) also pointed out, the burning of fossil fuels and deforestation are altering the composition of the atmosphere and contributing to climate change.
Unfortunately, the activity of burning or combusting fossil fuels releases various kinds of hazardous substances and pollutants which eventually leads to changes in the environment; such as climate change, global warming, and changes in environmental health. Let us start with the change in climate or climate change. For over the past 150 years, the burning of fossil fuels, such as coal and oil have caused the concentrations of heat-trapping "greenhouse gases" to increase significantly in our atmosphere. These gases prevent heat from escaping to space, somewhat like the glass panels of a greenhouse. It would change our climate, but it would not bring us close to the level of uninhabitable Venus.
The main GHGs within the atmosphere are Carbon dioxide (CO2) and water vapor (H2O). Others like methane (CH4) or nitrous oxide (N2O) also contribute to the natural greenhouse effect, although present only in very small amounts. Without these GHGs and their warming effect no life could exist on our planet, because the average temperature would be -0.4ºF. However, since the beginning of industrialization in the late 18th century the concentration of GHG in the atmosphere increased significantly causing more heat to be confined in the atmosphere, thus heating the earth
Global warming has been an issue since factories were introduced to this world; gases and toxins are being highly exposed into our atmosphere causing a tremendous reaction to the balance of nature. This is where one ecological system cannot function without the other throwing off the equilibrium in the world, and causes bad weather patterns. Scientists since 1970 have been warning the government that automobiles and factories are emitting a high level of
In this food chain of climate change, the major sub category is the constant temperatures change. It begins from Global Warming, which is a result of pollution. Where is all this pollution coming from? The answer is the human race. Driving cars that release off fumes, the burning of coal, and fossil fuels, people who don’t recycle.
With urbanization comes expansion when this happens cities must make more roads, buildings, roads and homes to accommodate its population. When this happens there are large pieces of land that are destroyed reducing natural recourses and increasing greenhouse gases. This causes a massive amount of air pollution to one general area. Although carbon dioxide is a massive cause to air pollution outdoors there are still many indoor atmosphere pollutions that we breathe in every day. Cigarette smoke is one of the leading causes of indoor pollution in homes, the cigarette smoke a person breathes in does not only affect them personally but all the people around them as well.
They lose their habitat and forced to move to new location; besides, many cannot survive the deforestation that destroys their homes. It is undeniable that deforestation itself has extreme effect on Global warming and hurts the air. Global warming means that air and ocean temperature is increasing. Greenhouse gases exist primarily because of human activity. Unfortunately, humans are the most polluting species on the planet.
