Global Warming

I . Introduction

Every day we go about our own business . Many of us never take the time to look around and see how we are affecting our earth 's atmosphere Everywhere you look today you are bound to see some factory or machinery polluting our air . Just think how many times you have seen those large semi trucks or big fossil fuel factories emitting thick dark smoke into the atmosphere . We need to come to reality and realize that all that polluting

we have been doing over the last half-century is finally catching up to us . It is very easy to detect through scientific research that our earth 's climate is changing , Time magazine reports in its 2004 issue that the earth 's average temperature is increasing at a steady rate . Yes , we all have heard the term global warming however many people don 't know in depth what global warming is , or how our actions will affect our earth if we don 't respond to the issue . If we can educate ourselves on what global warming is and how it will affect us in the near and far future , we can then begin to change our old habits of polluting and create new habits and goals to living in a much healthier and cleaner environment

This study intent to (1 ) know the effect of global warming worldwide thus knowing the global warming and doomsday and (2 ) widen our knowledge about the ozone slayer and do the humans are the reasons of causing global warming or if its just a natural process that the earth goes through

A . Ozone Slayers

Ozone is an unstable oxygen that occurs naturally in the atmosphere (also called isothermal region , the upper portion of the atmosphere above 7 miles where clouds are rare . The ozone layer absorbs the dangerous ultraviolet-B (UV-B ) rays while it allows the needed safe light to pass through . Though easily broken down by other gases in the stratosphere , it is constantly being repaired by the sun 's rays However , man is destroying the ozone layer which serves as a protective umbrella against the sun 's harmful rays . In fact , the ozone layer is destroyed faster than the sun 's rays can produce it . It is being destroyed by industrial gases like CFCs (Simpson , 2000

CFCs were invented in 1930 but were discovered hazardous in 1974 - only after 44 years of use . CFCs , which are found everywhere , are used in foamed plastic production (insulators , cups , fast-food containers spray propellants , coolants (refrigerators , air-conditioners ) and solvent cleaner (electronic equipment .It is dismaying to know that ozone depletion can be found in the south (Antarctica ) and north (Greenland ) poles ( HYPERLINK "http /www .questia .com /SM .qst ?act adv contributors Edwin 20G 20Dolan d contributors Edwin G Dolan " Dolan , 2006 . According to British scientist Joe Farman , 40 percent of ozone depletion can be found in the South Pole . At the South Pole is a huge vortex with clouds...
