Rate Of Antarctic Ice Loss Triples In 10 Years; Average Loss 219 Billion Tons/Year 2012-17
Antarctica's ice sheet is melting at a rapidly increasing rate, now pouring more than 200 billion tonnes of ice into the ocean annually and raising sea levels half a millimetre every year, a team of 80 scientists has reported.
The rate of melting has tripled in the past decade, the study concluded. If the acceleration continues, some of scientists' worst fears about rising oceans could be realised, leaving low-lying cities and communities with less time to prepare than they had hoped.
The result also reinforces that nations have a short window - perhaps no more than a decade - to cut greenhouse gas emissions if they hope to avert some of the worst consequences of climate change.
Antarctica, the planet's largest ice sheet, lost 219 billion tonnes of ice annually from 2012 to 2017 - approximately triple the 73 billion tonne melt rate of a decade ago, the scientists concluded. From 1992 to 1997, Antarctica lost 49 billion tonnes of ice annually.
