Title: -Global warming

Short description: Global warming

Long description: 1. Coal-burning power plants, vehicle exhausts, factory smokestacks, and other waste vents of the human environment contribute about 22 billion tons of carbon dioxide and other " Greenhouse gases " into the earth's atmosphere each year. 2. Using motorised vehicles and machines and furnaces for heating and air condirioners for cooling comtribute to the rise in greenhouse gases being released. 3. Factories, power plants and oil refineries also increase the amount of greenhouse gases that are released. 4. Burning fossil fuels such as petroleum, gas and coal releases carbon dioxide. 5. The top five carbon dioxide producing countries are. (a.) The United States (b.) China (c.) Russia (d.) Japan (e.) India 6. Volcanic eruptions are another natural acticity that releases greenhouse gase. 7. The atmospheric concentration of carbon dioxide has increased by 31% above pre-industrial levels since 1750. 8. this is similar to what happens in a greenhouse used to keep plants in warm temperature. 9. With out the natural greenhouse effect, temperatures on Earth would be too low to sustain life. 10.Too much carbon traps too much heat and therefore temperatures rise.
