> But it might only take a few decades for Antarctica’s growth to reverse, according to Zwally. “If the losses of the Antarctic Peninsula and parts of West Antarctica continue to increase at the same rate they’ve been increasing for the last two decades, the losses will catch up with the long-term gain in East Antarctica in 20 or 30 years -- I don’t think there will be enough snowfall increase to offset these losses.”
> “The good news is that Antarctica is not currently contributing to sea level rise, but is taking 0.23 millimeters per year away,” Zwally said. “But this is also bad news. If the 0.27 millimeters per year of sea level rise attributed to Antarctica in the IPCC report is not really coming from Antarctica, there must be some other contribution to sea level rise that is not accounted for.”
It was gaining mass for a long, long time and that trend is reversing and it ultimately doesn't change the fact the sea level rise is still occurring despite the mass gain.
That isn't a 'so things happen' situation. It is a "Well, traditionally Antarctica gains X each year. The rate of this gain is offsetting the Y in losses for now but the rate of loss is accelerating and overall we are still losing ground regardless'.
