However, the ice is unlikely to stop shrinking. Arctic sea melts through the summer usually reaching its annual minimum in September.
On Sunday (Aug. 26), Arctic sea-ice extent fell to 1.58 million square miles (4.10 million square kilometers), surpassing the previous low, set on Sept. 18, 2007, the U.S. National Snow and Ice Data Center (NSIDC) reports. Sea-ice extent refers to the area of ocean covered at least 15 percent by sea ice, according to the NSIDC.
The record low, set in 2007, stood at 1.61 square miles (4.17 square kilometers).
