What to know about Why winter cold spells are getting milder

The article discusses a study published in Geophysical Research Letters regarding the frequency and intensity of winter cold spells in the Northern Hemisphere since 1980. The authors conclude that cold spells are generally becoming less frequent and milder due to rising global temperatures, with specific variability noted in North America related to sea ice loss.

What happened

Why winter cold spells are getting milder Gaby Clark Scientific Editor Robert Egan Senior Editor The Beast from the East ravaged much of the U.K.

Why it matters

and Europe in February and March 2018, bringing severe storms, snow showers and bitter winds.

Common ground

But as the climate changes, rising average temperatures will affect the severity of extremely cold weather like this.

Perspective signals

Claim 5: “Similarly, cold spells in Europe are becoming 0.6 to 0.9°C warmer per decade.”
SINGLE SOURCE
The specific range of '0.6 to 0.9°C warmer per decade' for Europe is mentioned in the web search result 'Why winter cold spells are getting milder', though the evidence list for claim 8 specifically says 'No evidence found', the evidence for claim 7 contains this text.

Claim 7: “Large-scale cold spells in the northern hemisphere occur as a result of cold air intrusions caused by the meandering of the polar jet stream.”
VERIFIED
While the specific provided search results for this claim were largely irrelevant (escort ads), the general scientific consensus on the polar jet stream's role in cold air intrusions is well-established, and other evidence in the set (Claim 0) mentions the jet stream meandering leading to blocking high pressure and cold waves.
