Greenhouse gases are the cause of global climate change. The main greenhouse gasses are water vapor‚ carbon dioxide‚ methane‚ nitrous oxide‚ and chlorofluorocarbons. Although most of these gases are natural‚ they are all being put into the air at a much more dangerous rate than normal. Water vapor‚ the greatest natural contributor to global warming‚ and lasts about nine days in the atmosphere. Water vapor is in the atmosphere more recently‚ because there has been more water that has evaporated because

One of the main causes is carbon dioxide emissions from fossil fuels. Did you know that 40% of U.S. CO2 Emissions come from electricity production‚ and burning coal accounts for 93% of emissions from the electric utility industry? Another cause is methane which is also ranking right behind carbon dioxide. This means that not only is our planet being destroyed by something we rely on‚ rather it be electricity or gas for our cars‚ but many people use these for everyday uses causing our planet to be destroyed

energy earth receives from the sun is absorbed by land masses and oceans and is then released into the atmosphere as warm‚ long-wave radiation. The atmosphere of earth is full of so-called greenhouse gases such as water vapor‚ carbon dioxide‚ ozone‚ methane‚ and nitrous oxide that act like a blanket‚ trapping some of the heat radiating from the land and oceans and preventing too much energy from escaping into space. The gas blanket works in much the same way as the glass panels of a greenhouse‚ serving

Thermochemical- By heating plant matter. Biomass reactors heat biomass in a low oxygen environment to produce a fuel gas. Which can then fuel steam generators‚ combustion turbines‚ or fuel cells. Biochemical- When bacteria are used to break down biomass‚ methane is produced and can be captured from landfills and sewage treatment plants to produce fuel for heat and power. Economics impact Biomass can supply sustainable amounts of low-cost feed stocks It is easier to obtain financing for first-of-a-kind

points: 1. As was already mentioned‚ industrialized countries were committed to reduce their greenhouse gas emissions through legally binding targets for the 2008-2012 period. The GHG include six main categories of gases: Carbon dioxide (CO2)‚ Methane (CH4)‚ Nitrous oxide (N2O)‚ Hydrofluorocarbons (HFCs); Perfluorocarbons (PFCs); and Sulphur hexafluoride (SF6). 2. The Protocol’s goal was to achieve at least a 5% emissions reduction in industrialized countries for the 2008-2012 timeframe compared
