Aerosol particles(???????? )

• Mainly from combustion of fossil fuels, e.g.
  carbon particle and sulfate
• Reflect sunlight and cause cooling
• Heavily polluted Eastern China has a decrease in
  maximum temperature of 0.6oC per 10 years.

10
Possible solutions

• Minimizing carbon dioxide emissions by using less
  fossil fuel, using fuel with higher efficiency
  (??) and hydrogen-to-carbon ratio, and imposing
  carbon taxes
• Use alternative renewable energy sources (????)
  and use energy more efficiently
• Carbon sequestration (??) injecting CO2 in deep
  oceans or underground iron fertilization
  growing plants so storing carbon in biomass
