Question

1. what is the biggest danger posed by global warming to people living in coastal areas? a. increased precipitation b. increased acidity of seawater c. lack of carbon dioxide in the atmosphere d. rising sea level

Explanation:

Global warming causes ice - sheets and glaciers to melt, leading to rising sea levels. This directly threatens coastal areas by causing flooding, erosion, and loss of land, which are major concerns for people living there. Increased precipitation may cause local flooding but is not the most significant long - term threat. Increased seawater acidity affects marine life more directly than human habitation in coastal areas. Lack of carbon dioxide is not a danger related to global warming for coastal residents.

Answer:

D. rising sea level
