Global Warming By: Ryan Collins and Nguyet Luong

What is Global Warming? is the increase in the average temperature of the Earth's near-surface air and oceans since the mid-20th century and its projected continuation. Global warming is the increase in the average temperature of the Earth's near-surface air and oceans since the mid-20th century and its projected continuation.

What are the causes? Global warming is due to excess pollution produced by many different sources such as power plants, transportation, deforestation and city gridlocks. Global warming is due to excess pollution produced by many different sources such as power plants, transportation, deforestation and city gridlocks.

Carbon Dioxide from Power Plants In 2002 about 40% of U.S. carbon dioxide emissions stem from the burning of fossil fuels for the purpose of electricity generation. Coal accounts for 93 percent of the emissions from the electric utility industry. In 2002 about 40% of U.S. carbon dioxide emissions stem from the burning of fossil fuels for the purpose of electricity generation. Coal accounts for 93 percent of the emissions from the electric utility industry. For the typical U.S. household, a metric ton of carbon equals about 10,000 miles of driving at 25 miles per gallon of gasoline or about one year of home heating using a natural gas-fired furnace or about four months of electricity from coal-fired generation. For the typical U.S. household, a metric ton of carbon equals about 10,000 miles of driving at 25 miles per gallon of gasoline or about one year of home heating using a natural gas-fired furnace or about four months of electricity from coal-fired generation. Natural gas gives off 50% of the carbon dioxide, the principal greenhouse gas, released by coal and 25% less carbon dioxide than oil.

Transportation About 33% of U.S carbon dioxide emissions comes from the burning of gasoline in internal-combustion engines of cars and light trucks. About 33% of U.S carbon dioxide emissions comes from the burning of gasoline in internal-combustion engines of cars and light trucks. The United States is the largest consumer of oil, using 20.4 million barrels per day. The United States is the largest consumer of oil, using 20.4 million barrels per day. In order for cars to run they burn fossil fuels. This emits carbon dioxide, which is the biggest factor in global warming. In order for cars to run they burn fossil fuels.

Deforestation After carbon emissions caused by humans, deforestation is the second principle cause of atmospheric carbon dioxide. After carbon emissions caused by humans, deforestation is the second principle cause of atmospheric carbon dioxide. Deforestation is responsible for % of all carbon emissions entering the atmosphere, by the burning and cutting of about 34 million acres of trees each year. Deforestation is responsible for % of all carbon emissions entering the atmosphere, by the burning and cutting of about 34 million acres of trees each year. We are losing millions of acres of rainforests each year, the equivalent in area to the size of Italy. The destroying of tropical forests alone is throwing hundreds of millions of tons of carbon dioxide into the atmosphere each year.

City Gridlocks It was found that drivers in Los Angeles and New York City alone wasted 600 million gallons of gas annually while just sitting in traffic. The 600 million gallons of gas translates to about 7.5 million tons of carbon dioxide in just those two cities.

Drive a fuel efficient car-A car that gets 30 mpg will emit about half the CO2 of a 15 mpg vehicle. Drive a fuel efficient car-A car that gets 30 mpg will emit about half the CO2 of a 15 mpg vehicle. Drive Slower-Fuel consumption is directly related to the amount of CO2 emitted while driving no matter what vehicle you drive. Drive Slower-Fuel consumption is directly related to the amount of CO2 emitted while driving no matter what vehicle you drive. Carpool-The average person drives about 3,000 miles to and from work every year. Not driving just one day a week can reduce CO2 emissions by about 8 pounds per week.
