Sorry but there,ll be no ice age any time soon.Theres just not enough info to prove anything on this subject. In my life time we,ll have some cold seasons and some mild ones.If we did get a hic up in the climate something completly mad would have to happen eg yellow stone volcanic euruption or a metor strike that put millions of tons of ash into the atmosphere causing a global instant cool down.An ice age is a human altering experance, ie kill us all off,in my opinion if the earth was to wobble on its axis and turn away from the sun then yes the northern hemisphere would cool down but when is that going to happen, last time i read it is supposed to happen in 13 thousand years
