Scientists believe that the increase in greenhouse gas concentration, especially of carbon dioxide, is being caused by the combustion of fossil fuels and other human activities. Fossil fuels burned to run cars and trucks, heat homes and businesses, and power factories are responsible for about 98% of the total U.S. emission of carbon dioxide, 24% of the methane emissions and 18% of nitrous oxide emissions. Also contributing a significant share of emissions is the increase in agriculture, deforestation, landfills, industrial production, and mining. Scientists predicted that in 1997 the United States was responsible for the emission of about one-fifth of the total global greenhouse gases. The total amount of future emissions depends on a range of factors, such as demographic, economic, and technological policy and institutional developments, making it difficult to estimate future emissions. Despite the difficulty scientists have made some predictions; they predict that by the year 2100, without emissions control policies, carbon dioxide concentrations will be 30-150% higher than they are today. Scientists also expect that the earth's average surface temperature could ride 1.6 - 6.3 degrees Fahrenheit by 2100. It is also expected that the sea level is likely to rise two feet along most the U.S. coast. Today, according to the Environmental Defense Fund (EDF), for every one person out of the six billion people on Earth, almost six tons of carbon dioxide re released into the atmosphere each year. Because of human activities, the atmospheric concentration of this greenhouse gas has risen by over 30% over the last 250 years. According to the EDS, people can reduce the amount of carbon dioxide and other greenhouse gases being mixed into the atmosphere. Using public transportation, walking or biking to school or work, or if you must drive, join a carpool and use a car that gets high mileage are suggested to lower carbon dioxide levels.
