In Antarctica, melting may beget ice
Disintegration of floating glaciers could be responsible for freezing of seawater

Melting may not be the destroyer of all ice. Melting ice shelves may actually spur the growth of sea ice in Antarctica.
While Arctic sea ice has dwindled, the extent of Antarctic sea ice has expanded by nearly 2 percent per decade since 1985. As the oceans have warmed in the same time period, deep ocean currents have carried heat to the deep waters surrounding Antarctica. The warmth may be melting the base of ice shelves, sections of Antarctica’s ice sheet that float over the ocean.
