Why extreme cold weather events still happen in a warming world

Extremely cold Arctic air and severe winter weather swept southward into much of the U.S. in mid-January 2024, breaking daily low temperature records from Montana to Texas. Tens of millions of people were affected by dangerously cold temperatures, and heavy lake-effect snow and snow squalls have had severe effects across the Great Lakes and Northeast regions.
These severe cold events occur when the polar jet stream – the familiar jet stream of winter that runs along the boundary between Arctic and more temperate air – dips deeply southward, bringing the cold Arctic air to regions that don’t often experience it.

An interesting aspect of these events is that they often occur in association with changes to another river of air even higher above the jet stream: the stratospheric polar vortex, a great stream of air moving around the North Pole in the middle of the stratosphere.
When this stratospheric vortex becomes disrupted or stretched, it can distort the jet stream as well, pushing it southward in some areas and causing cold air outbreaks.

The planet will be OK, as long as heat rises.

Hurricanes, cyclones, tornados, and twisters, are heat exchangers.

Uh huh. And some people are so happy they’re sad. Sometimes the light is so bright that it’s dark.

That’s true. Our climate changes all the time. It’s called weather.

Except that the world hasn't warmed in the last 20 years.
