New Delhi, Mar 28 (PTI) A new model using simulations to study the melting of Greenland Ice Sheet has determined two critical tipping points, in terms of carbon emissions, beyond each of which irreversible melting is expected to occur, according to a new study.

Releasing 1000 gigatonnes of carbon would cause the southern portion of the ice to melt, scientists said in the study.

They further said that releasing 2500 gigatonnes of carbon meant a permanent loss of nearly the entire ice sheet.
