Greenland is already suffering, each summer more and more of there ice is melting at an alarming rate, if half of greenland melts, and half of west antartica melt then sea level world wide will raise 20ft and we will have a chance of an ice age on our hands...
once the golf stream is shut off, an ice age will take about 10 years to form! that is NOTHING!!
Ah, but Greenland-ians are use to living in a freezing, inhospitable enviroment. When the second ice age come they will already have had decades of producing food in artic temperatures.
