Ultra flash cold events under global warming.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
It is widely assumed that global warming will make winters milder and reduce extreme cold. However, this assumption is contradicted by the recurrence of flash cold (FC) events-sudden, violent temperature drops that can freeze energy grids and infrastructure within hours. The 2021 North America freeze, which caused over $20 billion in losses, stands as a stark warning. Here, we find that while the world warms, the fate of these ultra FC events is diverging: they are fading over Eurasia but significantly intensifying over North America. By tracking the spatiotemporal evolution of these ultra FC events and characterizing their dynamic environment, we reveal that this contrast is driven by specific atmospheric circulation regimes. In North America, increasingly frequent Alaska-Arctic anticyclonic anomalies funnel cold air directly southward. Conversely, weakened Ural-Arctic cyclonic anomalies are cutting off the cold supply. Crucially, current climate models fail to reproduce this intercontinental divergence. Simulations largely miss these specific circulation regimes, leading models to underestimate the ultra FC risk. Our results expose a regional warming paradox: specific atmospheric circulation anomalies can transiently overwhelm background warming, creating a critical blind spot for energy security.
