What serious affects do ice ages have on people's lives?

Question

example: injuries or loss of life

Answer 1

Since there has not been an ice age during recorded history, nobody knows.

Are you asking what effect it would have?

Answer 2

A small ice age of 100 years occured during the middle ages in europe. They barely had summers. It resulted in massive starvation from no crops. As much as 1/3 of the population died.

Answer 3

Doesn't affect me at all.  The study of Noah's Flood could be fun too.
