riiiiight...(doktor evil thingy)
i don't know but 1 picture on the internet doesn't prove a lot, then again maybe everything.

let's assume that the ice caps were beginning to melt from 1979.
but the rate of melting could be NOT linear.
at the beginning ice melted very slowly. bigger mass.
and let's say that the intensity of "warming" the ice got bigger trough the years, -> more greenhouse gasses, then it is possible that the melting rate the last 5 years could be like x-times greater then the first 5 years...

but then again,why am i replying with my own theories instead of hard evidence???
