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
