How do humans affect the water and carbon cycle p2

Question 1

Fossil fuels

Answer 1

-in 2013 fossil fuels accounted for 87% of global energy consumption
-it releases 10billion tones of CO2 into atmosphere annually
-since 1750, 879GT of anthropogenic CO2 emissions have remained in atmosphere, raising CO2 conc from 280ppm to 400ppm

Question 2

Sequestration of waste carbon

Answer 2

Carbon capture and storage= capture and store CO2 released by power plant and industry. CO2 separated from power station emissions and compressed and transported by pipeline and injected into porpous rocks underground. This reduced CO2
-in USA 40% of CO2 emissions are from coal and gas power stations and CCS can reduce these by 80-90%
