= Global Warming: The big picture = = = = THE GREENHOUSE EFFECT: = = = = =   The greenhouse effect is the rise in temperature that the earth experiences because gases in the atmosphere trap energy in from the sun. The gases are carbon dioxide, methane, and water vapor; also know as the greenhouse gases. Without those gases, the heat would escape back into space and Earth would be about 60 °C colder. Sunlight enters the earth atmosphere, passing through all of the greenhouse gases. When it reaches the Earths surface, land and water absorb the sunlight. Once they are done, they give off there their own heat energy. Most of this energy is trapped by greenhouse gases while the extra energy is sent back to space. Because of how the gases warm the Earth, this process is called The Greenhouse Effect. It’s necessary to our survival because without it the earth wouldn’t be warm.

 Global warming is an average increase in the Earths temperature. Scientists discovered that the Earth’s temperature has risen about 1.4 degrees Fahrenheit every year. The increase of the quantity of greenhouse gases is trapping more heat and increasing global temperatures, which makes a process that is harmful to our Earth. The gases from the Greenhouse effect keep the planet an average of 60 degrees Fahrenheit. A warmer Earth could lead to changes in rainfall patterns, melting of polar ice, a rise in sea level, and impacts on plants, wildlife, and humans.  With every 1 degree rise in temperature, foods like rice, wheat, and corn fall by 10%. ** GLOBAL WARMING: CONTRIBUTING FACTORS ** About 75% of the increase in atmospheric carbon dioxide is due to the burning of fossil fuels such as coal or petroleum. The burning of fossil fuels happens in places like factories. That increases the amount of carbon dioxide in the atmosphere. Other factors that are contributing to global warming are methane gases releases in animal waste. For example, cows have a large amount of methane gas in their waste, and there are about 1 million cows in the world. Increased cattle production is a big factor because it contributes to methane production, the use of fossil fuels, and deforestation. Automobiles are also a contributing factor, because they release carbon dioxide into the air. The increase in our population is an effect because of some of the things we use or do. For example, things like aerosol sprays, driving cars, and not recycling could harm our planet.

Electricity is mostly generated by burning coal, which makes some of the carbon dioxide that causes global warming. But people often leave on unnecessary lights in their houses, without caring. If the earth gets warmer, it will make the oceans warmer. That would cause more hurricanes. Another effect would be when ice glaciers melt, it could flood Boston. All of the people that live there would have to find someplace to live. They would also have to find new jobs, so it would economically be a disaster. Baseball eventually couldn’t be played, because the ash tree is in danger of disappearing. Ash Tree is what baseballs are made out of. Guacamole wouldn’t be able to be made anymore. Scientists predict that the hotter temperatures will cause a 40 percent drop in California’s avocado production over the next 40 years. They also think that the hotter temperatures are killing wild relatives of potato and peanut plants, so French fries wouldn’t be able to be made anymore. I ncreased CO2 levels will also cause poison ivy and other weeds to grow taller and lasher. Greenland is melting at a rate of 52 cubic miles per year. If Greenland’s 2.5 million cubic kilometers of ice were to melt, it would lead to a global sea level rise of 7.2 meters.  **WHAT YOUR AUDIENCE CAN DO DIFFERENTLY: One specific area of focus ** 
 * GLOBAL WARMING: LOCAL EFFECTS **
 *  More parents should drive hybrid cars because it’s a huge advantage in many ways. One is e ****lectric motors use no energy during idle, they turn off and use less than gas motors at low speeds. That means that during traffic, your car would give off less harmful gases into the air. In Boston, there is always traffic. So you would be giving off fewer emissions. Another benefit of having a gas motor is it charges the batteries while it’s running. Hybrids are the most gasoline efficient of all cars - they typically get 48 to 60 mpg. So you would save a lot of money on gas. Seeing that gas prices are going up, that’s a really good thing. **


 * A SUMMARY OF YOUR RESEARCH: **

In conclusion, Global warming should come to an end. No one realizes how harmful it is on our environment and how much it can affect us. People should be making everyday changes like getting Hybrid cars, or shutting of lights when you leave your house. Global Warming can take away everyday things like playing baseball, and eating seafood. Eventually, cities will be covered up water and tons of people will die.
