Machine-learning emergent constraints on surface albedo feedback over Arctic land regions.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Surface albedo feedback (SAF) amplifies warming in northern high latitudes, affecting the Arctic climate system, ecosystems, infrastructure, and global trade routes. However, Earth system models (ESMs) exhibit large uncertainties in SAF projections, complicating future Arctic warming estimates. Here, we develop a machine-learning method based on emergent constraints (ECs) and use in-situ observations to constrain SAF projections over Arctic land regions. Our approach leverages a physical relationship between historical albedo-temperature dynamics (1985-2014) and future SAF (2070-2099) across ESM ensembles. The constrained SAF is reduced by 0.29-0.52 W m
