jetstream != gulf stream

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.”

I guess it's like someone putting water on the coals in a sauna and the people feel a huge wave of heat due to the increased heat transfer, even though they've literally cooled down the coals.

Fair enough, I guess it's a pretty non-linear system!
