Answer to Question 1

ANSWER: Poor countries generally do not have the resources to build and maintain protective barriers. Annual floods and storms already contribute to many deaths in low-lying coastal areas.

Answer to Question 2

ANSWER: Dark soot in the cloud of pollutants over the Indian Ocean absorbs heat and warms the upper atmosphere. However, it also reduces heat to the lower atmosphere and cools the surface of the ocean, which reduces evaporation. This in turn increases the intensity of regional droughts because less moisture is available to fall as rain.
