Geoengineering

Geoengineering

1. Reasons for

   • To reduce carbon dioxide levels
   • Natural options may take too long
   • To reduce earths rising surface temperature

2. Strategies

   • Solar radiation management
     • Space mirrors
     • Reflective aerosols
     • Increase reflectiveness of clouds and land surfaces
   • Carbon dioxide removal
     • Iron fertilisation in oceans
     • Artificial Trees
     • Afforestation

3. Risks

   • Messing with nature
     • Reduced Rainfall
     • Increased natural disasters
     • Interference with natural weather phenomena
     • Changes to weather patterns
   • Project fails
     • Unknown long term effects
     • Global warming made worse
     • May be too late to invest in natural alternatives

4. Alternatives

   • Reduce carbon dioxide production
     • Stop burning fossil fuels
     • Stop mass animal farming
     • Government incentives for recycling
   • Invest in renewable energies
     • Solar
     • Wind
     • Biofuels
     • Hydro power
     • Electric cars
