too warm for the earth

The greenhouse effect keeps heat trapped in the earth atmosphere so when it is cold we will not freeze to death. The heat will go in the atmosphere and then will absorb in the surface. Some heat will stay in the surface and some will go into the atmosphere. Greenhouse gases keep the earth about 33 degrees Celsius warmer than it would be without these gases in the atmosphere. Over the past century, the Earth has increased in temperature by about .5 degrees Celsius and many scientists believe this is because of an increase in concentration of the main greenhouse gases which is carbon dioxide, methane, nitrous oxide, and fluorocarbons
 * THE GREENHOUSE EFFECT  **

** GLOBAL WARMING: T **** HE BIG PICTURE  ** . Global warming is closely linked to the enhanced greenhouse effect which is an increase in the concentration of [|greenhouse gases] in the atmosphere leading to an increase in the amount of infrared or thermal radiation near the surface. Most scientists agree that the enhanced greenhouse effect is leading to rising temperatures, referred to as global warming, and other changes in the atmospheric environment, known as climate change (a term that in common usage also includes natural changes). Carbon dioxide and other air pollution that is collecting in the atmosphere like a thickening blanket, trapping the sun's heat and causing the planet to warm up. Coal-burning power plants are the largest U.S. source of carbon dioxide pollution -- they produce 2.5 billion tons every year. Automobiles, the second largest source, create nearly 1.5 billion tons of CO 2 annually.
 * GLOBAL WARMING: CONTRIBUTING FACTORS **



Over the last century, the average temperature in Amherst, Massachusetts, has increased 2 � F, and precipitation has increased by up to 20% in many parts of the state. By 2100 temperatures could increase by about 4 � F (with a range of 1-8 � F) in winter and spring and about 5 � F (with a range of 2-10 � F) in summer and fall. Precipitation is estimated to increase by about 10% in spring and summer, 15% in fall, and 20-60% in wi nter. The amount of precipitation on extreme wet or snowy days in winter is likely to increase, while the frequency of extreme hot days in summer would also increase In 1999, Boston had a record 304 consecutive snowless days. Ground-level ozone concentrations exceed national health standards throughout the state and could increase as a result of higher temperatures brought on by global warming. All of Massachusetts is classified as a serious nonattainment area. Massachusetts loses an average of 65 acres to rising sea levels each year. Much of this loss occurs along the south-facing coast between Rhode Island and the outer shore of Cape Cod, including Nantucket and Martha's Vineyard.. At Boston, sea level is rising 11 inches per century, and it is likely to rise another 22 inches by 2100.
 * GLOBAL WARMING: LOCAL EFFECTS **

what I learned is that many problems are happening locally. Also I found out that NBA players actually help by reducing energy. They also recycle too. I found out what the greenhouse gasses were and how they contribute they are, carbon dioxide, methane, nitrous oxide, and fluorocarbons. I also learned that hybrid cars don’t impact global warming as much as regular cars.
 * WHAT YOU CAN DO DIFFERENTLY: One specific area of focus **Everyone. People need to recycle more often.  EVEN ATHLETES WANT TO HELP. NBA plans include doubling the number of recycling bins; featuring Phoenix Suns guard Steve Nash and assistant coach Dan Majerle in a recycling public-service announcement to be aired at the events; and using post-consumer products to build a playground as a community-service project. NBA will also buy 1500 megawatt hours of renewable-energy credits from [|APS] to offset the All-Star Game events. This is enough to power 100 average Arizona homes for a year. The project the credits will fund has not yet been determined project according to APS’ manager for renewable energy. If you walk to places more often then you save carbon dioxide admissions. Also you parents will save a lot of money and that could get more allowance. You can also get hybrid car. You use less gas and more traveling.
