Rising average global temperatures has once again made the North Pole a home to a lake in the middle of the Arctic ice cap. The same place was covered only with ice a month ago. North Pole Environmental Observatory has taken a photograph that shows a dramatic picture of the Arctic ice cap.
The average size of the ice cap has been shrinking over the past decades. The lowest point for Arctic sea ice was recorded last summer.
The situation in Antarctica is no way different, with sheets of ice meting rapidly. A study released earlier this week showed that Antarctic permafrost is melting, too. Permafrost is soil that has been below freezing temperatures for many years. Permafrost is melting at a higher pace than the melting ice. It is signal of rise in average temperatures.
Melting of Permafrost is happening at a faster pace in the Arctic as well. It is a serious concern because large amounts of methane are present in Arctic Ocean. Melting of ice will allow methane to escape in the atmosphere. Methane is a potent greenhouse gas, which has more heat than carbon dioxide.
According to The North Pole Environmental Observatory, "In 2012, on August 26, the Arctic sea ice extent reached the lowest value observed during the satellite record. Following that low, Arctic sea ice extent continued to drop, falling below 4 million square kilometers by September 5".
