The
sharp drop in Arctic sea ice area has been matched by a harder-to-see,
but equally sharp, drop in sea ice thickness. The combined result has
been a collapse in total sea ice volume — to one fifth of its level in 1980.

Back in September, Climate Progress reported
that the European Space Agency’s CryoSat-2 probe appeared to support
the key conclusion of the Pan-Arctic Ice Ocean Modeling and Assimilation
System (PIOMAS) at the University of Washington’s Polar Science Center:
Arctic sea ice volume has been collapsing much faster than sea ice area
(or extent) because the ice has been getting thinner and thinner.
