“There’s no sea ice at all,” she says. Tony Press, a former head of the Australian Antarctic Division, says it is “statistically not predictable.”What does that mean? “There’s a chance that it could come back again, but there’s also a very, very high chance that sea ice in Antarctica has moved into a new state,” Press says. Reducing fossil fuels may not save the west Antarctic ice sheet, but other climate impacts can be avoided through decisive action. “East Antarctica has about 10 times the volume of ice as west Antarctica, and we think it’s generally stable and likely to remain that way as long as emissions don’t rise much further,” she says.
