❄️ It’s freezing cold outside here in Germany, and this is an interesting explainer of why that is: a warming event in the polar region is leading to an early collapse of the polar vortex, so Europe and North America are flooded with cold air, while the North Pole is unusually warm. #weather #climate https://www.severe-weather.eu/global-weather/stratospheric-warming-watch-polar-vortex-collapse-cold-snow-impacts-coming-for-united-states-canada-europe-fa/
Stratospheric Warming Watch: Polar Vortex Collapse has begun, with cold air and snowfall impacts expected

A Stratospheric Warming is now collapsing the Polar Vortex, with polar air and snow forecast across the United States, Canada and Europe in December

The AMOC is "next".

🙄 It's already collapsing, but inertia, and time frame, means we won't really see it for a couple years yet.

I must stress that I am neither a mathematician, nor a climatologist.

It's not cold if it's only like this for a few days.

You can only call it cold if it lasts for a week or more.
