Hey, remember how the climate cultists said that the jet stream was moving south because of ‘climate change’? Like
The idea, first put forth in a 2012 paper by Jennifer Francis, now at the Woodwell Climate Research Center, and Stephen Vavrus, at the University of Wisconsin at Madison, is that two well-established trends — Arctic amplification (intensified global warming at higher latitudes) and depleted sea ice — can force the polar jet stream to dip farther south, thus causing more intense bouts of winter weather than might have otherwise occurred.
Over the past decade, this hypothesis sparked widespread public interest and scientific debate, as various high-profile cold waves and snow onslaughts hit North America and Eurasia, including a deadly, prolonged cold wave in Texas last February.
I can find plenty more of that in my archives and other sites. See, the jet stream was dipping south, causing Bad Winter Weather. But, now
Unprecedented? We know this how, exactly? Do we have specific scientific data from previous warm, and cool, Holocene periods? Oh, right, right, this isn’t about science, it’s about a doomsday cult trying to scare people into giving up their money and freedom (interestingly, these same people never think this will happen to themselves, just Other People)
But according to a recent study, the jet stream is shifting north as global temperatures rise. That’s because the delicate balance of warm and cold air that keeps the stream in place is getting disturbed. If greenhouse-gas emissions continue unabated, the study found, the jet stream will break out of its normal range by 2060.
“The ‘onset’ of the jet stream’s northward migration may have already begun,” Matthew Osman, a researcher at the University of Arizona’s Climate Systems Center who co-authored the study, told Insider.
“May have”? It is or it isn’t. The article is saying that it has started. A co-author is saying it might have begun. What’s the purpose of the study if they don’t know?
That would wreak havoc on weather in the northern hemisphere, bringing more extreme events like droughts and heat waves to southern Europe and the eastern US. More rain and flooding are expected in northern parts of Europe and Scandinavia, Osman said.
Sorry, I forget, the data and results are immaterial, it’s about the scaremongering.
Osman noted that the jet stream is capricious; the band’s location is constantly shifting as the temperature differential that causes it fluctuates. But his study took the long view, examining the stream’s location over the last 1,250 years. To reconstruct that past behavior, the researchers looked at ice core samples from 50 sites on the Greenland Ice Sheet that date back to the 8th century. The cores revealed how much snow had fallen, and when.
Then, using climate models, the team simulated where the jet stream might move over the next four decades if greenhouse-gas emissions continue at their present rate. The results showed that the wind band’s current movement threatens to exceed any previous shift.
So, they didn’t use actual measurements nor observations of the jet stream, they took ice cores from one small place, and then used models?
It’s also completely counterintuitive to what the cult has been telling us for years. And, if this becomes the norm, how will they blame Bad Winter Weather on the jet stream? Yes, yes, you’re right, they’ll find a way.
William Teach: So, they didn’t use actual measurements nor observations of the jet stream, they took ice cores from one small place, and then used models?
Teach is correct the NEWS REPORTS based on the PNAS article overstated the data. But please don’t attack the scientists unless you find fault with their data. Of course they North Atlantic ice core data to observe changes in the North Atlantic jet stream! Should have looked in Antarctica?
from the PNAS article:
The authors actually wrote that their data was consistent with natural variations!

Wow! Good for them.
Bwaha! Lolgf
