Got some references?

You might be thinking of the Gulf Stream, which is an oceanic current and definitively weakening, rather than the jet stream, which is an air current.
(Edit: though apparently the additional moisture in the Tropics more than counteracts any reduction in temperature difference: see link in Retric's comment)

That’s also what I read: The poles warm FASTER than the equator. Thus, the global temperature gradients are getting smaller. And as a result, not only does the Jetstream weaken: as a result, weather patterns become more stable which leads to greater continuous periods of draught or flooding.
jetstream != gulf stream

“The new study, by University of Chicago Professor Tiffany Shaw and NSF NCAR scientist Osamu Miyawaki, uses climate models to show that climate change intensifies this density contrast because moisture levels for air above the tropics will increase more than above the poles.”

Jet stream is also driven by temperature differences, like basically all weather. Heat engines.

It’s a heat engine but more than just temperature changes are occurring. “The new study, by University of Chicago Professor Tiffany Shaw and NSF NCAR scientist Osamu Miyawaki, uses climate models to show that climate change intensifies this density contrast because moisture levels for air above the tropics will increase more than above the poles.” https://news.ucar.edu/132935/jet-stream-winds-will-accelerat... .
Is there anything global warming can't do?
Whether it's responsible for more CAT - who knows?
