My sis is 9 yrs old and she has a speech about it. I'm helping her write it but I'm so lost. Here is what I have so far but I think it sounds boring and dumb! Can you help me rewrite it so its more interesting for 5th graders? I know this is asking for a lot but any ideas / suggestions / help would be so appreciated!! Thank you so much =)

Global Warming Speech
The Earth has warmed by about 1F over the past 100 years. But why? And how? Well, scientists are not exactly sure. The Earth could be getting warmer on its own, but many of the world's leading climate scientists think that things people do are helping to make the earth warmer.
Global warming is caused by greenhouse gases. Greenhouse gases such as CO2, methane, nitrous oxide, water vapour and ozone trap heat around the earth. Without them, heat would be lost into space and we'd all freeze. The trapping of heat around the earth is called the greenhouse effect because glass in a greenhouse traps heat in a similar way, keeping the inside of the greenhouse warm. The main greenhouse gas responsible or global warming is carbon dioxide. When we burn fossil fuels such as oil when we drive cars or in power plants and factories this relesaes huge amounts of CO2 into the atmosphere.
Greenhouse gases are like a blanket - if they are the right thickness. The Earht won't be too hot or too cold. Many experts think the way we burn fuel and add chemicals to the atmosphere is causing the blanket to become thicker. This makes the earth hotter, an effect known as global warming.
Scientists expect the average earth temp to increase by 6F over the next 100 years. This might not sound like much but it could change the Earth's climate as never before. At the peak of the past ice age the temp was only 7F colder than today and glaciers covered much of the world!
So what might happen?
It is important to understand that scientists don't know for sure what climate change will bring. Some changes brought about by climate change will be good. If you live in a very cool climate, warmer temperatures might be welcome. Days and nights could be more comfortable and people in the area may be able to grow different and better crops than they could before. But it is also true that changes in some places will not be very good at all.
Global warming can make sea levels higher. Warmer weather makes the glaciers melt. Sea levels are expected to rise as much as 3ft in the next century. This could cause coastal flooding. Global warming also increases extreme weather such as tsunamis, floods, hurricanes and heat waves and droughts. Some animals and plants may go extinct because they can't cope with the increasing temperatures.
Global warming will drastically change the world as we know it.
But dont worry, its not all doom and gloom! You can make a difference.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 green house gases that we put into the atmosphere.
Driving a car or using electricity is not wrong. We just have to be smart about it.Some people use less energy by carpooling. For example, four people can ride together in one car instead of driving four cars to work.
Whenever we use electricity, we help put greenhouse gases into the air. By turning off lights, the television, and the computer when you are through with them, you can help a lot.
Planting trees is fun and a great way to reduce greenhouse gases. Trees absorb carbon dioxide, a greenhouse gas, from the air.

Thats all I have so far...I still have to write a conclusion but I don't know what to say..
