Record minimum for Arctic sea ice

Help

Arctic sea ice has reached its minimum extent for the year, setting a record for the lowest summer cover since satellite data collection began.

The 2012 extent has fallen to 3.41 million sq km (1.32 million sq mi) - 50% lower than the 1979-2000 average.

Arctic sea ice has long been regarded as a sensitive indicator of changes in the climate.
