The Declining Trend of Arctic Sea‐Ice Extent (1979–2025): Segmented by Abrupt Change Points
Arctic sea‐ice extent (SIE), a high‐accuracy observable, is a key indicator for assessing sea‐ice state and its physical evolution. Extreme SIE losses thus often spark debates over potential Arctic tipping behavior and nonlinear threshold responses. Employing Arctic SIE from 1979 to 2025, this study investigated the lo...
