While increased snowfall in parts of Antarctica can temporarily offset regional ice losses, overall mass loss from the continent currently outpaces accumulation. Consequently, increased Antarctic precipitation does not prevent global sea level rise.
The claim asserts that increased precipitation in Antarctica will prevent global sea level rise. While several studies indicate that snow accumulation (surface mass balance) can partially compensate for ice losses or temporarily moderate short-term rates of mass loss (e.g., Shepherd et al., 2020; Medley et al., 2012; Bergman et al., 2023), comprehensive mass-balance assessments and sea-level budgets (e.g., Cazenave et al., 2018; Cazenave & Lemoine, 2009) show that overall ice sheet mass losses significantly outpace gains. Furthermore, continent-wide precipitation has not shown the dramatic, sustained increases required to offset ongoing dynamic ice discharges and melting (Monaghan et al., 2006). Therefore, the claim is refuted by the weight of the evidence.
