Human populations, throughout history tend form and congregate near water sources, including the coast. In 2010, 123.3 million people, or 39 percent of population of the United States lived in counties directly on the shoreline [NOAA]. World-wide, approximately 40% of the world’s population lives within 100 km of the coast [UN ESA]. One of the consequences of climate change will be an increase in the sea level rise. Communities in low-lying coastal areas are expected to see several effects. Which of the following are the expected to see? (Note: there are 4 potential effects. The choices ‘a’ through ‘e’ below are different combinations of the effects. Choose the most correct combination.) Submergence[1] Erosion[2] Flooding[3] Salt water contamination of fresh water sources[4]
