Carbon Stores

• 50% biomass is Carbon
• 18% of humans is Carbon
• Carbon Stores:

  Biosphere

  Atmosphere

  Pedosphere

  Fossil Fuels

  Hydrosphere

  Lithosphere
• Biosphere

  Trees, plants, living organisms

  560 Billion metric tonnes

  0.0012% of all Carbon

  High primary productivity- Tropical Rainforest

  Marine and Aquatic too
• Atmosphere

  750 Billion metric tonnes

  0.0017% of all Carbon

  Mostly CO2 and Methane

  Increased 36%
• Pedosphere

  0.0031%

  Soil/Peat/Permafrost

  Peat- 60% Carbon

  Dead Organic Matter
• Fossil Fuels

  4000 Billion metric tonnes

  0.004%
• Hydrosphere

  0.0038%

  38,000 Billion metric tonnes

  50 times more than atmosphere

  90% dissolved in Bicarbonate
• Lithosphere

  Rocks

  99.9% stored in marine sediments/sedimentary rock
