Record Antarctic ice gain linked to new tropical climate pathway
A new Nature study reports that Antarctica’s recent ice-mass gain from 2021 to 2023 was driven by an unusual climate pathway linking warm tropical ocean conditions to snowfall over the continent. The research combines satellite gravity observations, ice-core snow records, and atmospheric circulation modeling to show that the gain was likely a temporary anomaly rather than a lasting reversal of long-term ice loss.

Blind spots at Antarctic coasts limit sea level projections
An international review published in Reviews of Geophysics says persistent gaps in Antarctic coastal observations are limiting sea-level projections. The story emphasizes missing data on coastal bed topography and sub-ice-shelf cavities, which are crucial for understanding ice loss and future climate impacts.
Antarctica's coastal 'blind spots' limit sea level rise predictions, scientists warn
British Antarctic Survey says a new community-led review warns that major knowledge gaps along Antarctica’s coastline remain one of the biggest obstacles to reliable forecasts of future global sea level rise. The review combines observations, models, and theory to identify missing data on ice-ocean-atmosphere-solid Earth interactions.
New scientific review identifies Antarctic coastal blind spots limiting predictions
This release highlights the same international review of Antarctica’s coastal zone, focusing on how incomplete observations continue to restrict estimates of Antarctic ice loss and sea-level rise. It notes that the paper synthesizes current understanding of ice, ocean, atmosphere, and solid Earth interactions across the continent’s coast.
