It’s winter in the Southern Hemisphere, when ice typically forms around Antarctica.
But this year, that growth has been stunted, hitting a record low by a wide margin.
The sharp drop in sea ice is alarming scientists and raising concerns about its vital role in regulating ocean and air temperatures, circulating ocean water and maintaining an ecosystem crucial for everything from microscopic plankton to the continent’s iconic penguins.
“This year is really different,” said Ted Scambos, a senior research scientist at the University of Colorado Boulder and an Antarctica expert at the National Snow and Ice Data Center.
“It’s a very sudden change.”A continued decline in Antarctic sea ice would have global consequences by exposing more of the continent’s ice sheet to the open ocean, allowing it to melt and break off more easily, contributing to rising sea levels that affect coastal populations around the world.
