In the Media: Antarctic ice loss has tripled in a decade. If that continues we are in serious trouble

The melt rate has tripled in the past decade, the study concluded. If the acceleration continues, some of scientists’ worst fears about rising oceans could be realized, leaving low-lying cities and communities with less time to prepare than they’d hoped.

Antarctica, the planet’s largest ice sheet, lost 219 billion tons of ice annually from 2012 through 2017 – approximately triple the 73 billion ton melt rate of a decade ago, the scientists concluded. From 1992 through 1997, Antarctica lost 49 billion tons of ice annually.

“If you start removing mass from there, you can have a very large scale evacuation of ice into the ocean and significant sea level rise,” she continued.

The research was covered by a number of media sources, including the National Post, the Toronto Star, the Times of India, and the Houston Chronicle.
