#2> The Prosser report outlines one of the primary reasons for the increase in CAT events as the intensification of the jet streams, driven by the warming of the planet. As global temperatures rise, the temperature gradients between the equator and the poles become more pronounced, strengthening the jet streams and increasing the likelihood of turbulence .
I was under the impression that, as the poles are MORE affected by global warming, the jet stream is becoming weaker? is that incorrect?

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.

Exactly, air currents are becoming stronger with warmer conditions, but the gulfstream being a water current it is expected to become weaker.

To muddle things even further, there is a (jet) aircraft manufacturer called Gulfstream (https://en.wikipedia.org/wiki/Gulfstream_Aerospace).
...but I fully agree with the rest of your 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

#9I wonder if this is like an immune system response by mother nature, it’s attacking the thing that’s warming it up i.e. air travel? Self correcting systems

That is correct, as a longer term trend at least while paradoxically, we are also seeing periods of record strength in the Jet Streams.
The truth is there are many oscillations and teleconnections(themselves being impacted by global warming) which influences this temperature gradient on a local/seasonal basis. QBO, El Nino/La Nina and mountain torque events to name a few can move and shift heat at the tropopause in a short period of time and is why we see this wider variance at both ends of the spectrum.
