How is an increase in carbon in the atmosphere likely to affect coastal areas such as those in north carolina? a. plant growth and pollution are likely to increase b. flooding and erosion are likely to decrease c. plant growth and pollution are likely to decrease d. flooding and erosion are likely to increase

The answer is; D

An increase in carbon (usually carbon dioxide and methane) in the atmosphere increases the greenhouse effect  on the surface of the earth. This is because carbon dioxide and methane are greenhouse gases that warm up the planet ( causing climate change) by trapping UV light from the sun. The ice sheets in the polar regions begin to melt due to a warming planet and the ocean levels rise. This causes flooding in the coastal regions  and the higher tidal ranges erode the beaches.

um i think it might be a car?
