RV, As one of the links I poted shows Antartica is colder than ever and the ice sheets expand and contract as ice moves from the interior outward. Things change, Greenland use to be Green! The Vikings settled and later abandoned Greenland when it became inhospitable and they could no longer carry on trade.
Satiev, Yes.

oc, Saying Greenland used to be green is a bit misleading.
It may have been a little greener during the middle ages than it is today. But it's not like the whole place was warm.
Also, it is still green in some places.

GNP, It was settled by a hardy group of people called Vikings (they called it Greenland, not me), it was abandoned by the same hardy group of people, they abandoned it for a reason, climate changed and they could no longer maintain the outpost, Erik the Red was the last man out. This is a documented historical event, there are plenty of records surrounding it as it occured in the 13th century I believe.

The glaciers on Greenland are receding at this moment in time. In my personal opinion, I think that most of it has to do with natural factors, but some of it could be man-made. As you said, the temperature cycles anyway, so that is why I think it is probably natural more than man-made. I don't think Greenland was really "green". It was warmer than it is today, but the name has always been misleading.
