While the whale carcass is one reason for the polar bear bonanza, scientists wonder if there isn't another reason. Namely, the record retreat of Arctic sea ice from the northeast coast of Alaska into the Beaufort Sea.
The new record minimum measures almost 300,000 square miles less than the previous lowest extent in the satellite record, set in mid-September 2007, of 1.61 million square miles (4.17 million square kilometers). For comparison, the state of Texas measures around 268,600 square miles.
Arctic sea ice extent averaged for September 2012 was 3.61 million square kilometers (1.39 million square miles). This was 3.43 million square kilometers (1.32 million square miles) below the 1979 to 2000 average extent. September 2012 ice extent was 690,000 square kilometers (270,000 square miles) less than the previous record low for the month that occurred in 2007.
The extent of Arctic summer sea ice has decreased sharply over the past several decades (Stroeve and others, 2007).
