low sea ice production.
2012's
sea ice area and extent were already trending
low this year, but damage done to the thin and

low is set.
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 area seen during May.

sea ice area and
sea ice extent graphs track
lower than previous record years, despite weather that until recently would completely stall the decline.

A well - known example of this is the melting of land - based

lower sea ice concentration that accentuated throughout the summer season.
