1. Carbon Cycle and Carbon Emissions By Jordan, Forrest, Erik, Dalton, Skyler

2. The Carbon Cycle  The carbon cycle is the biogeochemical (life/earth/chemical) cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth.  Exists in atmosphere mostly as CO2.  Oceans contain about 60 gigatons of carbon.

3. Carbon Cycle The cycle is usually thought of as four major reservoirs of carbon interconnected by pathways of exchange. These reservoirs are: 1. The atmosphere. 2. The terrestrial biosphere, which is usually defined to include fresh water systems and non-living organic material, such as soil carbon. 3. The oceans, including dissolved non-organic carbon and living and non-living marine biota 4. The sediments including fossil fuels.

4. Released Carbon Carbon is released in multiple ways 1. Exothermic reactions or chemical reaction, releases energy in the form of heat. 2. Decay of plant and animal matter. 3. Cement production. 4. Volcanic eruptions. 5. Burning fossil fuels. 6. Natural gas releases carbon also. 7. And so on…

5. Carbon Emission These are the most abundant gasses in order: These are the most abundant gasses in order: -Water vapor -Carbon dioxide -Methane -Nitrous oxide -Ozone (trioxygen) -Chlorofluorocarbons (CFCs). Water vapor contributes to about 36-70% of the greenhouse effect.

6. Solutions to Carbon Emissions  Increased legislation against logging, mining, and other industrial giants  Increased benefits for the consumer to be economically friendly  Tax benefits to be more carbon neutral, for the average person and business  Limit to how much carbon can be produced per person per year

7. Per Capita Release of Greenhouse Gas From green (0) to red (9). Measured in tons.

8. Human Impact  Release of greenhouse gasses.  The burning of fossil fuels.  Results in greenhouse gas which leads to global warming.  Clearing and burning of forests, which releases a lot of CO2 into the atmosphere.  Processes that remove carbon from the atmosphere are extremely slow; in 1999 2,244,804,000 metric tons of CO2 were put in the atmosphere.  Increased production, along with slow reduction, means way more carbon.
