With a lobotomy it might be ok, but for any normal person it's too
full of contradiction (suck-and-pull)(and now Nasa adds in the
mountain belts pushing slabs down) Or are they quite happy to put
their name to nonsense, in the name of promulgating 'education'.

So why do you think (apart from 'lobotomy') they don't do it? Any
normal person would have to think there might be some 'alternative
view' but thee isn't.

(lobotomy again)

Climate change is already in there. The main thing is in the helicity
of the aggregate of transforms (parallel thread)
