"Scientists: Loss Of Antarctic Ice May Be Climate Tipping Point"

"CANBERRA — Rapid loss of Antarctic sea ice could be a tipping point for the global climate, causing sea level rises, changes to ocean currents and loss of marine life that are impossible to reverse, a scientific study published on Thursday said.

The paper in the journal Nature aimed to describe in previously unseen detail the interlocking effects of global warming on the Antarctic, the frozen continent at the planet's South Pole.

"Evidence is emerging for rapid, interacting and sometimes self-perpetuating changes in the Antarctic environment," it said.

The study gathered data from observations, ice cores and ship logbooks to chart long-term changes in the area of sea ice, putting into context a rapid decline in recent years."
