Scientific consensus regarding the link between global warming and cold weather extremes remains contested, as observational data and certain mechanistic studies suggest Arctic amplification can intensify winter cold outbreaks, while other empirical analyses and climate models find little detectable trend or connection between warming and mid-latitude cold extremes.

The claim addresses whether scientific consensus attributes cold weather extremes to global warming. The provided literature reveals a genuine division: some papers (e.g., [3], [9]) support the physical link between Arctic warming, polar vortex disruption, and severe winter weather, while others (e.g., [0], [6]) report no detectable trend or limited surface impact from such mechanisms, highlighting ongoing divergences between observations and models. Because there are valid sources on both sides showing active scientific debate and conflicting findings, the verdict is CONTESTED.
