Arctic sea ice reaches record low, NASA says
27 August 2012
The Arctic has lost more sea ice this year than at any time since satellite records began in 1979, NASA says. Scientists involved in the calculations say it is part of a fundamental change.
What is more, sea ice normally reaches its low point in September so it is thought likely that this year's melt will continue to grow.
NASA says the extent of sea ice was 1.58m sq miles (4.1m sq km) compared with a previous low of 1.61m sq miles (4.17m sq km) on 18 September 2007.
