Good points snipped.

I will never understand smart people being obtuse about such a simple
matter.

There's nothing harder than to change a mind that has fixed views about
something that is backed by the perception that "its always been like
this so its ALWAYS gonna be like this".

Sorry, but when the CO2 content of the atmosphere has risen from 340 ppm
in 1980 to 400ppm in 2017 (15% in 37 years) AND the heat from burning all
that carbon-based fuel has been pumped into the environment, then
something is going to happen.

I've certainly noticed changes in UK weather patterns over the 18 years
I've been flying gliders and am just surprised that others haven't also
noticed them. Changes like the disappearance of ideal XC conditions in
May when a strong northerly brings cold air down under a high pressure
ridge. Like the observation that the jet stream used to be over the UK in
winter and well north of us in summer. Now its over us in summer and over
France in winter.
