Answer to Question 1

Answer: Warming temperatures will melt glacial ice, exposing more land. Land will absorb heat better than glacial ice, which reflects it. The ground is warmer and there is less ice to reflect solar radiation, so temperatures will warm, which will melt more ice and expose more land, and so on.
