Like the title says, I know that global warming does produce colder winters but I’m unable to explain how.

They cause more variance in temps as weather patterns destabilize.

Take for example, the Polar Vortexes we hear about from time to time that bring super cold temps. Normally, there is a tightly spinning vortex of cold air over the North Pole. Looks like a tightly formed hurricane, but instead of a tropical storm it’s extremely cold. Now, weaken that air mass with warmer temperatures globally, and the tight spiral weakens, loosens, unravels and whisps of it dip further down beyond the arctic circle and bring that super cold air down with them. Not as intense as it was, but spreads further out.
