Recent studies have used satellite data to estimate the response of top‐of‐atmosphere (TOA) radiative fluxes to surface temperature changes in the Arctic. The satellite‐observed radiative response is indicative of Arctic climate sensitivity that determines future Arctic warming. However, it remains ambiguous whether the satellite‐observed radiative response is invariable because the time period covered by satellite data reflects a rapidly changing transient Arctic climate state with considerable sea ice loss. Using NASA’s CERES observations from 2000 to 2018, this study evaluates the invariability of the radiative response by comparing the radiative response of high sea ice concentrations (SICs) period to that of low SIC period. The results show that the net radiative response remains approximately unchanged regardless of the SIC (–0.19 ± 0.44 W m‐2K‐1 and 0.15 ± 0.16 W m‐2K‐1 for high and low SIC periods, respectively). In addition, seven of the eleven models from the CMIP6 demonstrated that the modeled radiative responses are stable. The ERA‐interim reanalysis estimates show that regionally confined changes in individual radiative feedbacks such as albedo, lapse rate, water vapor, and clouds do not vary considerably. Consequently, we infer that the radiative response in the Arctic may remain stable even under rapid Arctic climate change. Hence, the Arctic climate sensitivity can be quantified with present satellite observations.
