Global warming was leading to an "irreversible" mass melting of the Antarctic ice and purging carbon from the atmosphere was the only solution to slow the process, an Australian climate scientist told Reuters on Wednesday.
Recent human activity has intensified global warming, which could result in a mass melting of Antarctica, said Zoe Thomas, a research fellow at the University of New South Wales who was part of an international team of scientists that recently published a paper on Antarctic ice melting.
The study showed the world could lose most of the West Antarctic Ice Sheet, which rests on the seabed and is fringed by floating ice, in a warmer world.
"What we're seeing with the West Antarctic Ice Sheet, that this starting of the melt, once we reach a certain threshold, will continue despite our efforts to stop it. The only thing that would slow down the ice melting was if economies across the world began de-carbonizing themselves," Thomas told Reuters.
"Once we commit to this de-carbonized future, then we can start thinking about potential options for trying to remove carbon from the atmosphere," she added.
Many advanced economies have pledged to cut carbon emissions to net zero by 2050 though Australia is largely seen as dragging its feet on the issue despite recently suffering one of its worst bushfire seasons ever.
