We saw a lot of this last year... Not good for the plants (or critters). Temperature extremes can cause hibernating/dormant life-forms to wake up before winter is over!

Experts issue warning about powerful weather phenomenon that could soon impact US: 'This looks to be a prolonged event'

Story by Timothy McGill, November 20, 2025

Excerpt: "The forecast now is calling for the country's rollercoaster ride of temperatures to continue. Weather whiplash saw at least 90 cold records fall from Nov. 9-12, followed by at least 40 record highs broken in a single day, only around a week later. The U.S. could now be on the cusp of a record-breaking cold snap settling in about a week from now.

"Our overheating planet is weakening and destabilizing the #PolarVortex, driven by changes in the Arctic. The region is warming almost four times faster than the global average. Our warming world is supercharging this phenomenon known as #ArcticAmplification."

They also wrote prose on the Conversation https://theconversation.com/unprecedented-heat-in-the-north-atlantic-ocean-kickstarted-europes-hellish-2023-summer-now-we-know-what-caused-it-258061

Low surface wind speed led to shallower-than-normal ocean mixing which enabled heating the surface more.
Less clouds from shipping SO2 were only marginally responsible and only in small pockets.

Okay. But where did the wind go?
Surface wind is impacted by jetstream. And I think, the jetstream got diverted in June and July 2023 to Northern Greenland. Due to low spring snow cover in Eastern Canada which led to dry soil – which in turn gets hotter than wet soil.
And according to
"Summer atmospheric circulation over Greenland in response to Arctic amplification and diminished spring snow cover over Canada" by
Preece et al 2023
https://www.nature.com/articles/s41467-023-39466-6
that hot soil in Eastern Canada leads to a High over Greenland – and a low over the #ColdBlob
East Canada was ablaze in June July 2023 suggesting dry and hence hot soil =perfect conditions for a North Greenland High, diverting the jetstream.
