= = = = = THE G REENHOUSE EFFECT  = The greenhouse effect is a naturally occurring process that helps in heating the Earth's surface and atmosphere. The greenhouse effect occurs from heated gases getting trapped in the atmosphere. Some greenhouse gases occur naturally such as carbon dioxide, water vapor and methane. Humans also add to the greenhouse effect such as in the use of fossil fuels in cars. In order for us to live we need the greenhouse effect. Without it the temperatures will go down 60 degrees F colder at night and hotter during the day; because the heat will be escaping from the earth into space. Then plants will die and there will be no oxygen to breathe.



GLOBAL WARMING: THE BIG PICTURE
Global warming is part of the greenhouse effect but, is mainly caused by humans. The natural greenhouse effect warms up the earth; global warming causes the earth to heat up more then it should be heating up.

Contributing factors to global warming are Aerosol gases from spray cans, fossil fuel gases from cars and factories along with the cutting down of trees. All of these gases are going to the earth atmosphere and it is making the earth hotter. The trees help absorb the suns heat; if you take down the trees the bear grounds will make the earth heat up more.
 * GLOBAL WARMING: CONTRIBUTING FACTORS **

Scientists have track that in North American springs are coming earlier. The evidence is that the snow is melting earlier. The global warming is causing the polar ice caps to melt and make the seas rise. The water will go on the land and there will be a lot of water covering the land. If global warming keeps happening we will have no snow to do sledding, make snowman, snowboarding. Thunderstorms will start to increase due to the hot weather conditions.
 * GLOBAL WARMING: LOCAL EFFECTS **

If my family were to replace one regular light bulb in their home with a energy-saving compact fluorescent bulb they will save 67 dollars in there energy costs over the bulb life time. Also they will be preventing 1,000 pounds of carbon dioxide from going into the atmosphere from power plants.
 * WHAT YOUR AUDIENCE CAN DO DIFFERENTLY: One specific area of focus **

I think that everybody should take a part in stopping global warming. If we all did just one thing to help stop global warming,it would make a big difference.I have leaned alot about Global Warming; more then I knew before.
