There is a great icecap up to 3,000 meter to 10,000 ft thick in the interior of the country. This can be recognized as the largest accumulation of snow and ice in the northern hemisphere. In the north of Greenland the table of Thule represents the most of the interior ice-cap.
Greenland Weather includes a true Arctic climate, where the temperature is only above freezing for brief periods in the summer.

The ice-cap of Greenland is the source of some of the coldest air to affect northwest Europe.
