How is an increase in carbon in the atmosphere likely to affect coastal areas such as those in north carolina?

An increase in carbon in the atmosphere would likely be due to increased carbon dioxide gas resulting mainly from the burning of fossil fuels plus deforestation results in global warming. Global warming is causing glaciers to melt including both alpine glaciers like those in BC Canada and also continental glaciers like the ones in say, Greenland and Antarctica.The melting of glaciers will cause a rise in sea levels which can result in low-lying areas like the coast of North Carolina being inundated.
