Deep learning reveals enhanced ENSO predictability under historical anthropogenic forcing.
Article in Science advances, 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
Understanding how ENSO predictability responds to climate change is essential for improving future climate projections. In this study, we apply a deep learning model-convolutional neural network with a leave-one-out model strategy to Coupled Model Intercomparison Project Phase 6 (CMIP6) historical and preindustrial control simulations. We find that El Niño-Southern Oscillation (ENSO) predictability is statistically enhanced by 14.0 ± 1.8% enhancement under historical anthropogenic forcing. This improvement is linked to changes in key ocean-atmosphere feedbacks. Under historical forcing, the equatorial Pacific shows a shoaling of the thermocline. As a result, the surface ocean becomes more sensitive to wind forcing, and subsurface temperature becomes more responsive to thermocline variations. These processes strengthen the three-dimensional advective and thermocline feedbacks, which together enhance ENSO predictability. These findings highlight the importance of anthropogenic forcing in shaping ENSO predictability in a warming climate.
