Question 2 How does the burning of fossil fuels contribute to the net increase in atmospheric carbon?

А
Photosynthesis is reduced by virtue of increased smoke and haze.
B
Carbon released by the burning is not in a form that can be readily absorbed by plants, leaving residual carbon in the atmosphere
С
Carbon that has been sequestered underground is added to the carbon cycling between the atmosphere and the bioschere
D
Carbon released by the burning is more easily absorbed in the atmosphere than that produced by natural means
E
Carbon released by the burning increases plant growth, producing more carbon for the atmosphere
