New research warns abrupt Antarctic ice and ocean changes could raise sea levels and threaten ecosystems globally.

Antarctic sea ice might be one of those tipping points within the Earth's system, warned Australian Antarctic Division head scientist Nerilie Abram. Her statement reflects a new scientific perspective: the rapid decline of Antarctic sea ice is greater than a regional anomaly but a potential catalyst for irreversible global climate alterations.

A study warned that Antarctic ice loss could cause more warming in the region and beyond, and could push some marine species toward extinction.Scientists on Wednesday warned that abrupt and potentially irreversible changes are occurring in Antarctica.
