Carbon Cycle and Energy Security
- Carbon Pump
  - Biological- phytoplankton in the ocean sequester carbon dioxide through photosynthesis, from atmospheric to ocean store
  - Biogeochemical- the whole of the carbon cycle including geological and biological
- Carbon Sequestration
  - Thermohaline Circulation
    - Terrestrial Stores (land)
- Mangroves - Carbon Rich Soils, Anaerobic Processes, Respiration and Decomposition very slowly Carbon Stored for any years
- Tundra Soils - Permafrost, permanently frozen pockets of carbon
- Tropical Forests - Positive Feedback Loss of trees, less rainfall, fires, fewer rain-forests
- The Natural Greenhouse Effect - natural process by which the earths temp is maintained
- The Enhanced Greenhouse Effect - the increase in atmospheric CO2 has increased global temp
- Radiative Forcing Effect (RFE) - The capacity of a gas to affect the energy balance its ability to absorb and retain heat
- Primary Productivity - the rate at which plants produce biomass
- Greeh House Gases (GHG)% produced
  - Nitrous Oxide - 3%
    - Halocarbons - 1%
      - Methane - 7%
        Carbon Dioxide - 89%
        Water Vapour - negligible
- Energy Security, affordable sources of energy.
  - Primary- Coal, Oil, Natural Gas
    - Secondary - Electricity
- London 1.8 tonnes f carbon per capita per year
  - Peru - villages have solar powers, 500,000 people have energy
- Norway - uses HEP and exports Natural Gas much more energy secure than the UK. want to be carbon neutral by 2050
- Energy Pathways, Pipelines, shipping routes, transmission lines, roads and rail
  - Prone to Disruption
- Unconventional Fossil Fules
  - Tar Sands, Deep Water Oil, Shale Gas, Oil Shale
- Hinkley Point C Nuclear Changing Energy Mix
  - Biofuel
    - Hydrogen Fuel Cells
- Climate Change- ocean acidification, Coral Reefs
