"The current pace of global heating risks unleashing “rapid and unstoppable”
sea level rise from the melting of Antarctica’s vast ice sheet, a new research
paper has warned.
Unless planet-heating emissions are swiftly reduced to meet the goals of the
Paris climate agreement, the world faces a situation where there is an “abrupt
jump” in the pace of Antarctic ice loss around 2060, the study states, fueling
sea level rise and placing coastal cities in greater peril.
“If the world warms up at a rate dictated by current policies we will see the
Antarctic system start to get away from us around 2060,” said Robert DeConto,
an expert in polar climate change at the University of Massachusetts and lead
author of the study. “Once you put enough heat into the climate system, you are
going to lose those ice shelves, and once that is set in motion you can’t
reverse it.”
DeConto added: “The oceans would have to cool back down before the ice sheet
could heal, which would take a very long time. On a societal timescale it would
essentially be a permanent change.”"
