• FF Consumption Rates
• FF Exhaustion
• Carbon Dioxide Levels
• GHG and Earth Temperature
• Impacts

World Energy Reserves

• Crude Oil
• 1.22 Trillion Barrels
• Coal
• 998 Billion Tons
• Natural Gas
• 6.28 Quadrillion ft3 (STP)
• Total Carbon Mass 832 Trillion kg

By Fuel Mass
4
Global Oil Consumption

• Projections
• USA
• Annual change 1.2/yr
• Developing Countries (Asia)
• Annual change 3.0/yr
• World
• Annual change 1.4/yr

5
Reserve Lifetimes

• Crude Oil exhaustion in 2037

6
Reserve Lifetimes

• Natural Gas will be exhausted in 2043

7
Reserve Lifetimes

• Coal will be exhausted in 2072

8
Carbon Emissions

• Carbon Dioxide
• 100 yr Lifetime
• Current Atmospheric Levels
• 383 ppm
• Avg. increase (1960 Present) 1.5 ppm/yr
• 200 Billion kg (Current total release)
• Future Atmospheric Levels
• Global Carbon release (65 yrs away)
• 770 ppm Max
• 101 increase (2x)

9
GHG and Temperature

• Temperature Increases and CO2 levels are
  correlated

10
Future Temperature
11
Temperatures

• Future Global Avg. Temperature
• 67 F
• Current Avg. Temperature
• 59 F
• Change 8 F

12
Impacts

• Significant reduction of ice sheets
• Likely complete melting
• Vegetation
• Increased vegetation in temperate mid-high
  latitudes
• Seas
• Slowing of ocean conveyer
• Rising Water levels and temperatures
• Weather
• Increased storm intensity
• Arable land
• Increased dessert area
• Reduced rain / increased flooding

13
Impacts

• Animal Population dynamics
• Insect boom from warmer winters
• Decreasing fish populations
• Increasing jellyfish populations

14
Effort Needed

• CO2 emissions must be curbed drastically and soon
• Climate change will occur unless changes are made
• Alternative fuels and energies deserve higher
  priority in government and industry funding
