Interest of choosing this project
Many kids already know about climate change but not a lot on the ozone layer. Climate change is a really serious problem that is happening right now. But that is not the only problem. The ozone layer is part of the atmosphere and is very important to our survival. Unfortunatly it is in danger. Although we cannot repair the damage in the ozone layer we can stop destroying more of it. I think that kids can also help slow down climate change when they try.
Summary of Research
What is Climate Change?
Climate change is the effect of gases getting trapped in the atmosphere. When the gases are trapped the planet gets warmer and we call that climate change. Gases are made by cars, planes, trucks, factories, and ships. The most critical gases are methane, CO-2(carbon dioxide), and CO (carbon monoxide).

What is the ozone layer?
The ozone layer is one of the layers in the atmosphere. This layer protects us from the radiation rays of the sun. Without it we would have greater risks of skin cancer and health problems. Ozone is a gas that normally helps us while it is in the ozone layer but becomes a health problem at ground level where it can cause headaches and affects negativlely the respitory system of humans.

Summary of Research


Effects of climate change

Climate change causes a lot of problems on our planet. The gases we produce cannot escape the planet and planet Earth gets hotter. Ice starts to melt and all artic animals are in danger. When the ice melts there is more water in the ocean. So far the ocean has risen 7 inches. After the ice will have melted completely some places will be under water. Some places affected will be New Orleans, Boston, New York, and Miami. Countries like Bangladesh, the Netherlands, and many islands in the Indian and Pacific ocean could disappear completely. At the actual rate the ocean will rise 23 inches by 2100. Marine agriculture
will also be affected. Coral reefs are sensitive to high temperatures and
now that the oceans are getting hotter they are starting to bleach
and die. Extreme weather is more common because the warmer
oceans are more likely to create Hurricanes. Also tornadoes,
and wildfires are feeding from warmer air at ground leval.
Summary of Research
What affects the ozone layer?
In 1985 scientists discovered a hole in the ozone layer. They believe that gases from refrigerators, aresol cans, and foam packaging can make these holes. The risk of losing this layer would affect us seriously. Pollution reduced the amount of protection in the ozone layer a lot. Now the UV rays are dangerous and we have to put on more sun protection. The holes will never close but we can stop it from getting biger by using less of damaging gases. So far the
hole is as large as the United States, Canada, and Mexico
combined. Even though the hole is far from where we live it
will still affect us.
Climate Change and destruction of the Ozone Layer.

Evidence

Current Studies and Data about Climate Change
The NASA published: Ninety-seven percent of climate scientists agree that climate-warming trends over the past century are very likely due to human activities, and most of the leading scientific organizations worldwide have issued public statements endorsing this position.
Impact
on Adolescents
Young adolecents are in more danger with climate change and the ozone layer dissapearing because the cities that are going to go underwater one day still have citizens living there. Now that the ozone layer is disapearing kids have to wear more sun protection. But if they forget they can get serious sunburn or even worse, skin cancer.

What this article made me ponder
`
Pictures
The heat-trapping nature of carbon dioxide and other gases was demonstrated in the mid-19th century. Their ability to affect the transfer of infrared energy through the atmosphere is the scientific basis of many instruments flown by NASA. Increased levels of greenhouse gases must cause the Earth to warm in response.
Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show that the Earth’s climate responds to changes in solar output, in the Earth’s orbit, and in greenhouse gas levels. They also show that in the past, large changes in climate have happened very
quickly, geologically-speaking: in tens of years, not in millions or even
thousands.

When I read the article I started thinking about the question they wrote at the end : "What can you do to help stop climate change?" and really it is quite obvious, I can walk to school instead of riding in a car and use less energy in general. The damaging gases for the ozone layer that are in refrigerators, foam, and aresol cans can be used less and need to be subsituted.
How can the magnet program change this data?
How can you help the enviroment? Using a car takes up a lot of gas and that is more trapped in the atmosphere. Refrigerators use the bad gases that started the hole in the ozone layer. It woud be better that you don't leave the refrigerator door open too long when choosing something to eat. Foam packaging is also hurtful to the damaged layer and can be replaced by cardboard. Bicycles do not hurt the enviroment and would also be better for your health. One school magnet program can probably not change the data but through the television it is possible to tell more people that they can behave more evironmentally friendly - or in other words successful magnet projects need to be published.
Current data on the Ozone layer
Following are referable areas:

Australia 8,923,000 Sq Km
United States 9,363,130 Sq Km
Europe 10,498,000 Sq Km
Antarctica 13,340,000 Sq Km
Russia 17,078,000 Sq Km
North America 25,349,000 Sq Km
Africa 30,335,000 Sq Km
S. Pole to 70 S 15,300,000 Sq Km
S. Pole to 65 S 23,890,000 Sq Km

The total percent of depletion of the ozone layer is 50-75 %. The data listed down is the amount of how big the hole can get in each place
