Melting ice forms lake in the North Pole

Two weeks of unusually warm weather in the North Pole have caused a lake to form in mid-July.

The meltwater lake is approximately a foot-deep. According to the National Snow and Ice Data Center, temperatures in early July were 2 to 5 degrees Fahrenheit higher than average over most of the Arctic ocean.

July is the Arctic's melting month, when sea ice shrinks the fastest.

An Arctic cyclone is forecast for this week. Arctic cyclones can quicken the summer melt by churning up ocean water and further fracturing the ice.
