Arctic sea ice volume (the amount of three-dimensional space the sea ice occupies) and extent (how much sea ice covers the Arctic Ocean) have been declining since record-keeping began in the late 1970s and prior.


Additionally, Antarctic sea ice extent is currently below the long-term average of prior decades since 1979, when scientists started keeping track.
