The article itself is behind a paywall.

One thing I see is its focus on the East Antarctic Ice Sheet.

One of the citations is titled "Accelerated West Antarctic ice mass loss continues to outpace East Antarctic gains"

See for example https://svs.gsfc.nasa.gov/31158 from 2024:

Areas in East Antarctica experienced modest amounts of mass gain due to increased snow accumulation. However, this gain is more than offset by significant ice mass loss on the West Antarctic Ice Sheet (dark red) over the 21-year period.

Or from 2023 at https://www.antarcticajournal.com/antarctic-ice-sheet-mass-g...

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.”

So, if Antarctica is gaining ice mass on land, where is the sea level rise coming from?
