Arctic Sea Ice On Track For Another Record Summer Melt June 29, 2012

NOAA says the latest satellite observations suggest that Arctic sea ice continues to shrink and thin.
The rapid rate at which Arctic sea ice melted during the first half of June could lead to an even greater loss by September than was experienced during the record year of 2007.

The U.S. National Snow and Ice Data Center (NSIDC) says that on June 18, floating ice was 318,000 square miles less than on the same date in 2007.

The rate of melting averaged between 38,000 to 57,900 square miles per day, which is more than double the long-term average.

The retreat of Arctic ice coincides with the United States’ warmest spring on record and the warmest March through May period ever observed.

The NSIDC says it’s still early in the Arctic melt season, and changing weather patterns over the next three months will affect just how much sea ice eventually melts.
