Climate crisis may be increasing jet stream turbulence, study finds
Researchers say previous studies of the speed and location of the fastest part of the north Atlantic jet stream have found only small changes over time, although there are signs it is slowly shifting northward. Experts say the lack of dramatic alterations is because climate change produces competing effects at different altitudes.
The latest study, however, took a different approach. “Just because the speed isn’t changing, doesn’t mean the jet stream isn’t changing in other ways,” said Prof Paul Williams of the University of Reading, the lead author of the research.
His study, published in the journal Nature, looked at the change in wind speed with height, known as vertical shear. “The higher up you go, the windier it gets,” he said. Using three different datasets based on satellite observations, the team say they identified a 15% increase in vertical shear between 1979 and 2017, consistent with what would be expected from climate change.

I posted the article and quoted directly as I wanted to see if there was any real world experience reported here. It might be that some folk will say that they have noticed these effects, or, may now watch out for them. I considered the likely reaction before posting.

I started flying across the pond in 96, the difference i see between now and then is that the jets tend to be snake like rather than an arc. Thus, you cross more areas of different wind conditions therefore more turbulence.
As to the cause of the changing jets, I blame airline management.

This just goes to prove that "climate change" is a big scam. Sure it's happening but man doesn't stand a snowball's hope in hell of doing much about it, although the arrogant fraudsters are trying to scam the masses into believing that they can.

What is relevant is that in practice, governments ever aware of new sources of revenue are realising that "carbon budgets" could well be nice little earners.

I like to compare climate change with fire insurance - most people have fire insurance on their house because they *really* don't think it's going to burn down. BUT, the financial risk is so great you can't afford to chance it and the cost of insurance isn't that great. Same with climate change - most of the world's scientists say there's something to worry about, so I say let's take out some insurance. Maybe it's a waste of money - but the consequences if the scientists are right are pretty dire, so it's worth insuring against it.
But unfortunately climate change deniers are not rational....

I have read quite a lot on this subject and listened to many interviews with scientists who specialise in climate and related areas. I can't recall any who say man made climate change is bollox.

Climate has never been a stable entity since day 1. Climate has changed constantly over the centuries and did so long before man could be held accountable for those changes. So forgive me if I remain unconvinced that we, the human race are the catalysts.

There is no denying that man in the modern era has contributed to CO2 emissions which have heated up the earth, and most scientists agree on this point.
What they all can't agree on is to say it's the sole reason for climate change, and unfortunately too many people have run with it and made what they want out of it.

There is the IPCC reports are the result of collaboration between scientists around the world. The worlds peak science bodies agree with it. I have read some of them and they make sense to me to my ability to understand it.

The scientist doubters are a rag tag bunch that are slowly dying out. Much as those who never accepted relativity died off. Climate science is taught in Universities around the globe that is consistent with the IPCC reports.

RickNRoll, you believe what you want to mate, it's your right. Scientists have also been known to change their minds as time goes by. There's plenty of evidence of that too. I'll stick to my personal deduction: "climate changes and always will no matter what".

First it was global warming. Then it’s was climate change. And now it’s a climate crisis? Spare me.
