Answer:
the albedo will increase and the temperatures will drop
Step-by-step explanation:
If an ice age occurs, the Earth will cool off. The reason for this will be the increased albedo. The ice has high albedo, thus it is reflecting big portion of the sunlight instead of absorbing it. Because of the much lower absorption of sunlight, the Earth will start to cool off, eventually resulting in several degrees drop of the average temperatures around the whole planet. Apart from the drop in temperature, the Earth will also be drier, with decreased amounts of precipitation because there will be less evaporation from the water bodies, which will also be reduced in size because parts of them will be frozen.
