Today Arctic sea ice extent continued its plunge into record territory. According to measurements provided by the Japanese Space Agency (JAXA), current sea ice extent for August 29th was 3,863,000 square kilometers. This value is 84,000 square kilometers below yesterday’s value and nearly 400,000 square kilometers below the previous record set in 2007.

NSIDC also showed Arctic sea ice continuing its plunge into record territory today. The below image provides a good visual of the lowest sea ice coverage in the NSIDC record:

Arctic sea ice area melt also continued today reaching a new low of 2,570,000 square kilometers, according to reports from Cryosphere Today. This value is 420,000 square kilometers below the record low set in 2011.

Over the past week, all values for sea ice area and extent have pushed to significant new lows. Given the current rates of melt, it appears possible that new records will approach or exceed 500,000 square kilometers below the previous record. By all measures this is a very significant loss of ice for one year.
