The Thwaites Glacier in Antarctica, undergoing significant ice loss since the 1940s due to climate changes and El Niño events, contributes to 4% of global sea-level rise. Researchers emphasize the ongoing retreat initiated by external factors like ocean and atmosphere circulation changes, highlighting the importance of understanding these dynamics for future sea-level rise projections.
