Although the 2019-20 winter was on the mild side here in Southern Ontario, it wasn’t everywhere, especially in the last few years, during which we’ve had some extended deep freezes which naturally led to some skeptical mutterings about where global warming ended up. Always ready with an answer, a few years ago the alarmists conjured up a theory that global warming is causing the jet stream to get wavier, pushing the boundary of Arctic air further south, thereby allowing the frigid air masses to travel farther and plunge frigid human masses into the icy grip of global warming, or something. We reported previously that the conjured explanation didn’t hold up when scientists looked for a mechanism to explain why the jet stream would be getting bendier. Now they’ve discovered something else: the jet stream isn’t getting bendier at all. Sometimes cold weather is just cold weather.

The article at phys.org reports on a new study from scientists in the UK who note that while the Arctic has warmed there’s no evidence connecting it to the waviness of the jet stream. In fact if there’s a connection, it goes in the opposite direction: “[They] believe any link is more likely to be a result of random fluctuations in the jet stream influencing Arctic temperatures, rather than the other way around.”

Aaaah! What? Random? Apparently so. With more data at hand and a better understanding of the system, the scientists conclude: “The well-publicised idea that Arctic warming is leading to a wavier jet stream just does not hold up to scrutiny.”

As Tony Heller previously reported, in the 1970s climate scientists confidently blamed a wavier polar vortex on the global cooling trend, then they turned around and blamed it on global warming. So we already had reason to suspect they were just making up theories on the fly. And it seems they were.
