One Of Antarctica’s Most Menacing Glaciers Has A Tipping Point – IFLScience

Glaciologists have long feared certain Antarctic Glaciers have tipping points beyond which their decline will be almost impossible to reverse. Proof in specific cases has been harder, but now one team say they have confirmed the Pine Island Glacier, one of the greatest threats to global sea level, fits the bill and we are getting frighteningly close. 
Tipping points represent perhaps the greatest source of uncertainty in climate research. Until one is reached, a system may shift in one direction…
