Interesting.
I find it confusing that cooling global temperatures brought on by a natural change in solar activity reducing the amount of water evaporation and impacting rain fall is universally accepted as the cause for the sudden expansion of the Sahara Desert over 10,000 years ago, yet when applied to events in other parts of the planet they are shrugged off as non-events.
It is no big deal when geologists say the Sahara has gone through such cycles in the past and will return to a more savanna like environment as the earth naturally warms from the changing solar cycles, yet those same natural temperature changes are blamed on humans when talking about glaciers in Greenland.
It needs to be reminded that Greenland is called such because it was largely green in the early history of man living there. From a planetary history standpoint, being covered in ice is the recent reoccurrence of a long running cycle.
