Estimating the magnitude of radiative and non-radiative feedbacks is key for understanding the climate dynamics of polar regions. Here the authors propose an inclusive methodology to quantify the influence of all those feedbacks, stimulating more sys

The increase of climate sensitivity in the latest Earth system models (ESMs) is primarily attributed to a larger extratropical cloud response to warming. This stronger cloud feedback is thought to be partly driven by a greater ratio of supercooled li

Abstract The increase of carbon-dioxide-doubling-induced warming (climate sensitivity) in the latest climate models is primarily attributed to a larger extratropical cloud feedback. This is thought to be partly driven by a greater ratio of supercoole

La télédétection spatiale touche un public nombreux et varié parce qu'elle contribue à faire progresser les connaissances sur l'environnement et le climat de la Terre et parce qu'une mission spatiale d'observation de la Terre agrège de nombreus

Abstract During the Arctic night, clouds regulate surface energy budgets through longwave warming alone. During fall, any increase in low‐level clouds will increase surface cloud warming and could potentially delay sea ice formation. While an incre

Cloud susceptibility to aerosols in models frequently exceeds satellite estimates. Here the authors show that the discrepancy can be explained by retrieval limitations especially in clean environments, suggesting that conventional comparison strategi
