Antarc­tica lost 40 per cent ice sheets due to melt­ing from 2012 to 2017, con­tribut­ing to 0.6 mm of sea level rise per year

THE RATE of melt­ing from the ice sheets of Antarc­tica has tripled in the past five years as com­pared to the melt­ing two decades ago. An ex­haus­tive re­search, in­volv­ing 84 sci­en­tists from 44 in­ter­na­tional bod­ies, shows that Antarc­tica has lost al­most 3 tril­lion tonnes of ice since 1992; 40 per cent of the loss took place from 2012 to 2017 dur­ing which the pole could have con­trib­uted 0.6 mm of sea level rise a year. The melt­ing is hap­pen­ing so fast that Antarc­tica alone can add more than 15 cm to sea level rise by the end of the cen­tury, projects the study, pub­lished in Na­ture. So far, Antarc­tica has been con­sid­ered the more re­silient of the two poles to cli­mate change.„
