According to a new study, Antarctica will reach a climate tipping point by ________ year ?

a) 2050
b) 2100
c) 2060
d) 2070

A new study published in the journal Nature shows that the Antarctica ice sheet could reach a tipping point by about 2060. This means if the global greenhouse emissions continue at the current rate, the Antarctica Ice Sheet (AIS) will cross a critical threshold leading to an irreversible global sea-level rise.
