A few days ago, someone posted a blog post here on HN [1] explaining the phenomenon which causes this: https://www.severe-weather.eu/global-weather/polar-vortex-co...

We are also entering a solar minimum, the last one was linked to a “little ice age” in Europe.

I don’t know how climate change will affect this. But we might be in for an interesting few years.

No we just left a minimum, there’s been sunspots of opposite polarity appearing since early 2019 if memory serves - round about that timeframe anyway but the end of the minimum wasn’t confirmed until earlier in 2020.

It wasn’t a Maunder Minimum.

For the next 4 years or so we’ll proceed to maximum then back down to the next minimum thereafter.

> The Maunder Minimum occurred with a much longer period of lower-than-average European temperatures which is likely to have been primarily caused by volcanic activity.[citation needed]

There are literally two citations immediately following that sentence in the Wikipedia article.

As I recall, many comments there were very dismissive. I wonder if that senrinent will change.

I don't think the two are related. At least, I haven't heard anyone mention it as the cause.
