Unprecedented? Jet Stream Crosses Equator.
This dumbassery has since been debunked by Jason Samehow, see this from Phil Plait, nada to see here.
The jet stream in the Northern Hemisphere has crossed the equator and joined up with the jet stream in the Southern Hemisphere. This seems like new behaviour, and indicates that climate system mayhem is ongoing.
Our climate system behaviour continues to surprise us in new and scary ways that we have never anticipated, or even seen before.
Welcome to climate chaos. We must declare a global climate emergency.
