Where are the ice sheets in the present-day climate?
In the northern hemisphere, Greenland is covered by an
enormous ice sheet which is a few kilometers thick and more than five times
larger than the state of California in area. If this ice sheet were to melt,
global sea level would rise by about 7 meters.
This is all that remains of the huge
ice sheets that covered North America and Eurasia during
the last glacial maximum, about 20,000 years ago.
