State‐Dependence of Polar Amplification in an Idealized GCM

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Polar amplification (PA) is a robust feature of contemporary climate change, but its state‐dependence across different climate conditions is poorly understood despite potential relevance to paleoclimate records and future projections. Here we examine the state‐dependence of PA across a wide range of climate states in an idealized moist general
