NSIDC has just released its June analysis.
Arctic sea ice extent for June 2011 was the second lowest in the satellite data record since 1979, continuing the trend of declining summer ice cover. Average ice extent fell below that for June 2007, which had the lowest minimum ice extent at the end of summer. However, ice extent this year was greater than in June 2010. The sea ice has entered a critical period of the melt season: weather over the next few weeks will determine whether the Arctic sea ice cover will again approach record lows.
Ice extent during June 2011 declined at an average rate of 80,800 square kilometers (31,200 square miles) per day, about 50% faster than the average decline rate for June 1979 to 2000. Ice extent declined more slowly than in June 2010, the year with the lowest average ice extent for the month. However, ice declined faster than in June 2007, the year when September sea ice extent reached the lowest in the satellite record. Ice loss in the Kara Sea was especially fast, more than double the average rate and close to double the rate of the past four years (2007 to 2010). Sea ice has largely disappeared in the southern Kara Sea, which normally still has considerable ice cover at this time of year.
Air temperatures for June were 1 to 4 degrees Celsius (2 to 7 degrees Fahrenheit) warmer than average over most of the Arctic Ocean, except in the Beaufort and Greenland seas, where temperatures were near normal or slightly below normal. High pressure dominated most of the central Arctic, with the highest pressures over the Beaufort Sea. The monthly averaged pressure field shows a circulation pattern somewhat similar to a pattern known as the dipole anomaly, with unusually high pressure over the Beaufort Sea and unusually low pressure over central Siberia. Similar patterns have become common in recent summers.
