Preface
  • Energy > development
    • First stage - agriculture
    • Second stage - fossil fuel
  • Sustainable development  > more energy
    • Fossil fuel emissions may affect climate
    • We can control
    • We will need more energy
3
Postulated Problem
  • Greenhouse gases (GHG) from fossil fuels
    • Warming the atmosphere
  • Is climate change happening?
    • Hard to prove
  • Postulate we must control GHG
    • How can we manage?


4
A Diffident Approach
  • Recommended by some
    • Still more improvement in energy efficiency
    • Conserve
  • This approach not a solution
    • Improving efficiency increases applications
    • Counters conservation
    • Emissions increase




5
A Different Approach
  • Learn from the carbon cycle
    • Tackle the problem head on
    • Manage atmospheric greenhouse gases

6
Carbon Cycle Overview
7
The Human Perturbation
8
Carbon Cycling on Land
9
The Ocean Carbon Cycle
10
Carbon Cycle Summary
  • Humans control much of carbon cycle
    • 24 billion tonnes of plant production
    • Fossil fuels 6 billion tonnes
  • Opportunity
    • Integrate energy use with carbon control



11
Renewable Energy

13
Fertilization of the Ocean
14
Agriculture - Forestry
  • Major component of the carbon cycle
    • Four  times bigger than fossil fuel
  • Agriculture increases carbon uptake
    • Fertilizer, irrigation, plant breeding
15
Soil Carbon Sequestration
16
Charcoal and Soil
  • Charcoal is a component of soil
    • more durable than other organic forms
    • likely produced by fires
  • Ancient Amazonian agriculture
    • some areas of rich black soil
    • possibly man made centuries ago
    • charcoal  from variation of slash and burn?
17
 Charcoal-Fertilizer Process
18
Nuclear Energy
19
Challenge
  • Significance to carbon cycle?
    • Limited reserves – once through fuel cycle
    • Alternate fuel cycles
    • Breeding?
    • Fusion?
    • Beyond electricity
