If the upper temperature goal set in the Paris Agreement is exceeded, the melting Antarctic ice sheet could cause annual average sea-level rise of 0.07 inches (0.18cm) globally in 2060 and beyond, said the study published in the journal Under the 2015 Paris Agreement, more than 190 countries agreed to hold global average temperature rise to "well below" 2C above pre-industrial times and strive for a limit of 1.5C.
