Antarctica’s Astonishing Rebound: Ice Sheet Grows for the First Time in Decades

From SciTechDaily. Excerpts:

"The Antarctic Ice Sheet (AIS) has historically lost mass, significantly contributing to sea-level rise, with intensified losses in West Antarctica and parts of East Antarctica, particularly from 2011–2020. However, between 2021 and 2023, driven by anomalous precipitation, the AIS experienced a record-breaking mass gain, even reversing trends in critical glacier basins like Totten, Moscow, Denman, and Vincennes Bay.

Mass changes across the Antarctic ice sheet have been detected using satellite gravimetry, revealing significant instabilities in major glacier basins of East Antarctica as well as across the entire ice sheet."

"From 2002 to 2010, the AIS has experienced a mass loss with a change rate of –73.79±56.27 Gt/yr, which nearly doubled to –142.06±56.12 Gt/yr for the period 2011–2020. This accelerated mass loss was primarily related to intensified mass depletion in West Antarctica and the WL-QML region of East Antarctica. However, a significant reversal occurred thereafter, driven by anomalous precipitation accumulation, the AIS gained mass at a rate of 107.79±74.90 Gt/yr between 2021 and 2023."
