The South Korean icebreaker "Araon" is entering the center of the Arctic Ocean.

Huge glaciers should have appeared by now but only broken pieces of ice are floating on the sea.

Ice in the Arctic began to rapidly disappear in 2000 and hit a record low in 2007. Levels have fallen 22 percent since the turn of the century.

Warmer water temperatures are largely to blame and changes in the ocean current caused by global warming.

At this pace, experts say glaciers could completely disappear from the Arctic Ocean by 2030.

If glaciers at both the North and South Pole melt entirely, the sea level will rise 60 meters and threaten humanity.
