Scientists have shed more light on the puzzling contradiction of increasing Antarctic sea ice in a warming world.
In
a new paper published in Nature Geoscience this week, researchers from
Monash University and the US-based National Center for Atmospheric
Research pointed to climate variability and a complex series of flow-on
effects between the tropical Pacific and Ross Sea.
Reasons why
the extent of Antarctic sea ice has increased since satellite records
began in 1979 have long confounded climate scientists.
The
Antarctic situation sits in stark contrast with the Arctic, where ice is
rapidly melting, and is not reflected in climate model predictions.
In
the new study, the researchers report that patterns of climate
variability and corresponding changes in water temperatures in the
tropical Pacific Ocean, and the Amundsen Sea off the coast of west
Antarctica, have changed ocean circulation in the Ross Sea, driving an
increase in sea ice.
