I read that last year’s super cold winter in northern Europe was caused by a change in air currents caused by melting of more of the Arctic Ocean. Very confusing.
You read right. The hare-brained “theory” is that arctic warming throws off ‘hurricanes” of sub-zero temps.

If you really pin them with questions as to why weather does what it does they really don’t have any answers.
