Global expansion of the sensitive aerosol-limited marine cloud regime under emission reductions.

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
Aerosol-cloud interactions (ACIs) are fundamentally nonlinear, with their strongest climatic effects emerging where cloud properties are highly sensitive to aerosol changes-the aerosol-limited regime. Quantifying this regime's evolution is therefore critical for constraining uncertainties in climate forcing and future projections. By integrating satellite observations with climate model simulations, we map this regime globally and track its recent change. We find it expanded by 4.8% per decade over the past 20 years, primarily due to a sharp increase (∼14.7% per decade) in the Northern Hemisphere driven by anthropogenic emission reductions. Under a strong emission reduction pathway, its frequency is projected to double or triple in key ocean regions. This systematic shift pushes marine clouds into a state of heightened aerosol sensitivity, thereby amplifying the cloud-mediated radiative response to aerosol changes. Our findings underscore the need to account for this evolving sensitivity in climate projections.
