This year's minimum follows a record - breaking summer of low sea ice extents in the Arctic.

Arctic sea ice is already beginning to melt and recede, setting the stage for a very low sea - ice minimum extent that the center will declare in September, he added.

In other words, Arctic sea ice extent has been lower than it was in 1938 - 43 during the entire satellite record, and the current average summer extent is approximately 4.3 million square kilometers lower than the 1940 minimum.

New University of Colorado at Boulder calculations indicate the record low minimum extent of sea ice across the Arctic last September has a three - in - five chance of being shattered again in 2008 because of continued warming temperatures and a preponderance of younger, thinner ice.

Arctic sea ice in 2017 had record - low extents for much of the first five months of the year, though it recovered a bit after that to show only the eight lowest summer minimum on record.

Reasoning for a decrease in sea ice extent from recent years, perhaps approaching new record - low minimum, focuses on the below - normal sea ice thickness overall, the thinning of sea ice in coastal seas, rotting of old multi-year sea ice, warm temperatures in April and May 2010, and the rapid loss of sea ice area seen during May.

For Antarctica, the lowest maximum extent, recorded on September 12, follows a record low minimum sea ice coverage recorded on March 1 after the summer thaw, he said.
