In any case, this is not a political belief, is it? It's a global problem and not a political one.
In the latest poll I've found (YouGov, April '22) 71% of the public accept that it's happening and 65% are worried.
I'm afraid that it is a political belief and the monarch is supposed to be apolitical.
OTOH, if he is backed by nearly three quarters of the population one wonders if it could be what sparks off the Revolution 
That would be interesting, wouldn't it? The monarch starting a revolution against his own government...
