The Ozone Layer and Global Warming

1. The Ozone Layer and Global Warming By Magnet Fofanah

2. The Ozone Layer – What is it? • The Ozone Layer is a thick layer in the Earth’s stratosphere that protects the earth from harmful ultraviolet rays omitting from the sun. • Ozone is actually made from ultraviolet rays. • Ozone consists of three oxygen atoms rather than the usual two. It is usually formed when radiation or electrical discharge separates the two oxygen molecule atoms which then recombines with other oxygen molecules to form ozone (O3).

3. The Ozone Layer – The Effect? • Certain products release chemicals called chloroflurocarbons which makes its way up into the earth’s stratosphere and eats away at the ozone layer. • Although stratospheric ozone is good, there is ozone produced at lower levels when sunlight rays interact with atmospheric gases made from pollution in urban areas. • This can cause breathing problems for humans • Usually occurs in the summertime, when there is more pollution

4. The Ozone Layer – How to Fix it? • To stop the deterioration of the ozone layer, companies have cut down the use of chloroflurocarbons in products. • Stop putting halo-methanes in the air • All countries of the world come together and agree to use different refrigerants.

5. The Ozone Layer – Importance? • The discussion of the Ozone Layer is important because it plays a great deal in future humanity. • Without the ozone layer, the earth is naked to harmful ultraviolet rays. • If the ozone layer deteriorates thoroughly, there’s no saying what will be of life on earth.

6. Global Warming – What Is It? • According to Merriem-Webster’s dictionary, global warming is an increase in the earth's atmospheric and oceanic temperatures due to the greenhouse effect resulting especially from pollution. • Causes: • Greenhouse Gases • Most of the greenhouse gases omitted are fossil fuels that come from cars, factories and electricity products • Carbon Dioxide is responsible for the most heating up of the earth • Other heat-trapping gases like methane and halo-methanes • Soot-covered ice absorbs heat from sun • Less polar and glacial ice to reflect heat back into space • Since 1990, there has been a 20 percent increase in CO2 emissions.

7. Global Warming – The Effects? • Ice melting all over the world • Increased precipitation and stronger storms • Sea level rises faster • Ecosystems will begin to alter due to migration of animals • Less fresh water will be available! • The food chain will be affected

8. Global Warming – How to Fix it? • In order to slow down global warming or attempt to stop it, big changes worldwide have to happen. • We have to • Stop burning fossil fuels and use other means of power such as hydropower, solar power, wind power, natural gas, etc. • Attempt trapping CO2 (this is dangerous because it has to be contained FOREVER to avoid future damages from it being released again).

10. Global Warming – The Importance? It is important to understand global warming and its effects because it affects not only what happens to the earth today but what it will be in the future. In order to keep the earth from slowly fading, countries worldwide have to come together and develop a solution.

11. The Difference Between the Ozone Layer and Global Warming Ozone and the Green house effect have a direct relationship. Earth’s temperature increase due to global warming Sun’s rays are able to reach the earth (ozone layer depleted) Global warming is experienced Green house effect created by the refrigerants prevents the same rays from escaping back into the atmosphere
