    GLOBAL WARMING AND ITS EFFECTS ON

    SOCIETY

    LITERATURE REVIEW:

    Through the eyes of most scientists, global warming is seen as a very serious and severe

    threat. The actions taken by humans, such as industry and consumption of fossil fuels

    plus the increase in population and agriculture have played a big part in global warming.

    If something is not done soon the results could be very bad.

    By the middle of the twenty first century, there is evidence that the Earth will be warmer

    than it has been at any time in human history, and quite possibly since the end of the

    dinosaurs, some 65 billion years ago. If we stay at the rate we our now (fossil fuel

    consumption / growth in population) then within the next two century the Earth's airmight not be fit to breath. Many people in the world do not think that this is a major

    concern and that it is normal for the Earth's temperature to increase. However, if this

    temperature increase is put into perspective of several hundred years, there will be

    many devastating effects. This is why most scientists view global warming as a very

    serious and severe threat. Global warming does not require a reduction of the standard

    of living of people. However it does demand a rapid shift in the patterns of consumption

    of fuels such as oil, coal, and natural gas, to an economy more reliant on solar energy,

    hydrogen gas, wind biomass, and other renewable energy sources.

    The term greenhouse effect is used to describe the increased warming of the Earth's

    surface and lower atmosphere due to increased levels of carbon dioxide and other

    atmospheric gases that absorb radiated energy in the atmosphere and then reradiate it

    back to the surface. But if it were not for the greenhouse effect, temperatures at the

    Earth's surface today would be much colder than they are now, and life as we know it

    could not exist.

    OBJECTIVES:

    Climate change may be a big problem, but there are many little things we can do to

    make a difference. If we try, most of us can do our part to reduce the amount of

    greenhouse gases that we put into the atmosphere. Many greenhouse gases come from

    things we do every day. As we have learned, these greenhouse gases trap energy in the

    atmosphere and make the Earth warmer. Some of these gasses occur naturally while

    others are caused by humans. The most common of these gasses that are causing the

    earth to heat up is the gas carbon dioxide (CO2). According to the ICCP the CO2

    emissions have grown between 1970 and 2004 by eighty percent. Emissions rose by 15.8

    percent from 1990 through 2004 and emissions and from 2003 through 2004 emissions

    increased by 1.7 percent. The main factors that contribute to the greenhouse gasses are

    economic growth in 2004, which lead to increased demand for electricity and fossilfuels. The expanding industrial production in energy-intensive industries, also

    increasing demand for electricity and fossil fuels, and increased travel all leading to

    higher rates of fuel consumption.

    So what can we do as individuals to help stop global warming? As individuals we can try

    to get global warming under control by slowing down the release of carbon dioxide and

    other heat-trapping greenhouse gases that we let into the atmosphere.

    Hypothesis:

    H1: Positive effects on environment

    H2: Non positive effects on environment

    METHODOLOGY:

    At the core of most proposals is the reduction of greenhouse gas emissions through

    reducing energy waste and switching to cleaner energy sources. Frequently discussed

    energy conservation methods include increasing the fuel efficiencyof vehicles (often

    throughhybrid,plug-in hybrid, and electric cars andimproving conventional

    automobiles), individual-lifestyle changes and changing business practices. Newly

    developed technologiesand currently available technologies including renewable energy

    (such as solar power, tidal and ocean energy,geothermal power, andwind power) and

    more controversiallynuclear power and the use ofcarbon sinks,carbon credits, and

    taxation are aimed more precisely at countering continued greenhouse gas emissions.

    More radical proposals which may be grouped with mitigation includebiosequestration

    of atmospheric carbon dioxide and geoengineering techniques ranging from carbon

    sequestration projects such ascarbon dioxide air capture, to solar radiation

    managementschemes such as the creation ofstratospheric sulfur aerosols. The ever-

    increasing global population and the planned growth of nationalGDPs based on current

    technologies are counter-productive to most of these proposals.

    CONCLUSION:

    In talking about global warming, we need to learn what causes the greenhouse effect.

    Rays from the sun are taken up and absorbed by water vapor that is natural in the

    atmosphere. The United States emits the largest manmade greenhouse gases in the

    world. As Americans we must realize the responsibility to reduce the emissions. (Gore,

    Albert) Water Vapor is eighty percent of greenhouse warming. The last twenty percent

    results from other gases that are in very little amounts. A huge absorber of the sun's

    heat rays is carbon dioxide. Us as humans release a lot of carbon dioxide. When fossil

    fuels are burned, they release big amounts of carbon dioxide.
