Antarctica projected to lose more ice than it gains this century, even if warming is limited to 1.5°C
The researchers write in The Conversation that they trained a machine-learning model on ice-sheet simulations and checked projections against satellite observations. They say extra snowfall is unlikely to offset the projected losses.
TLDR
A Nature Geoscience study’s observation-calibrated model puts the probability of Antarctic ice-sheet mass loss by 2100 at 92% even under the low-emissions SSP1–1.9 scenario. Writing in The Conversation, the researchers say extra snowfall is unlikely to offset losses driven by a warming ocean. Their projections show greater loss under higher emissions, though some ice-sheet processes are missing from the simulations used to train the model.
