- future Predictions
- The International Energy Agency estimates FF'S to remain the dominant energy source into 2030 (84%). NATURAL GAS will double, and OIL BARRELS must increase by 1.4 bil barrels a day to meet demands.
- It is predicted that Russia and the Middle East will be relied on more.
- Sir Nicholas Stern - "Climate change will cost the world 5-20% of world GDP".
- More extreme weather events and natural disasters
- a 2-3*C rise may reduce economic output by 3% due to reduction of crop yield. a 5*C rise means a 10% reduction - poorer countries find it hard to cope
- Ways to improve the future:
- Carbon Credits - each country can only release a certain amount of C
- Carbon Trading - if credits are not all used up- can be traded
- Green Taxation - tax increased on services not carbon-friendly
- Low Carbon Homes - High energy efficiency (such as insulation)
- Smart metres - measure energy output per appliance
- Hybrid/ electricity cars - powered by H fuel cells or electricity or a mixture with petrol
- POSITIVE feedback: Enhanced greenhouse effect; may destabilise system and may not be in equilibrium.
- Permafrost melting - released CO2 and CH4.
- Melting of sea ice - reduces albedo and increases heat of water - OCEAN WARMING (releases dissolved CO2).
- Reduced precipitation (resulting from deforestation)
- NEGATIVE feedback: maintains a stable state
- The International Energy Agency estimates FF'S to remain the dominant energy source into 2030 (84%). NATURAL GAS will double, and OIL BARRELS must increase by 1.4 bil barrels a day to meet demands.
