CCS INTRO BY HUANG LEI 12年12月10⽇星期⼀ Monitoring has shown that the amount of CO2 in the atmosphere is increasing, with atmospheric concentrations now approaching 400 ppm compared to pre- industrial levels of 280 ppm (IPCC 2007a). 12年12月10⽇星期⼀ The largest global source of fossil fuel emissions comes from coal-fired power plants, with around 9 Gt of CO2 emitted in 2011. 12年12月10⽇星期⼀ This elevated level of CO2 concentration enhances the greenhouse effect, leading to global warming. This rise in temperature causes the climate to change, sea levels to rise, and ocean and land environments to be affected. 12年12月10⽇星期⼀ This elevated level of CO2 concentration enhances the greenhouse effect, leading to global warming.
