Climate Change

As expected, the amount of sea ice in the Arctic has fallen to the lowest level on record.

Satellites tracking the extent of the sea ice found over the weekend that it covered about 1.58 million square miles, or less than 30 percent of the Arctic Ocean’s surface, scientists said. That is below the previous record low, set in 2007, but with weeks still to go in the summer melting season, it is clear that the record will be beaten by a wide margin.

Climate Change

Arctic sea ice is set to reach its lowest ever recorded extent as early as this weekend, signalling that man-made global warming is having a major impact on the polar region.

With the melt happening at an unprecedented rate of more than 100,000 sq km a day, and at least a week of further melt expected before ice begins to reform ahead of the northern winter, satellites are expected to confirm the new record – currently set in 2007.

The ice-free season is now far longer. Twenty years ago it was about a month. Now it’s three months. Temperatures last week in the Arctic were 14 degrees C.
