Weather (short term local fluctuations) is chaotic.
Climate (long term parameters) isn't.
As an example of how this can be so, consider the classic images of spinning wingnuts in space ( Dzhanibekov effect | Tennis racket theorem ).
The tumblings of the wingnut, moment to moment, are chaotic and unpredictable.
The long term trajectory of the wingnut is clear to see, the centre of mass arcs in a smooth manner and the eventual impact point on the hull can be marked in advance.
( In answer to your question, I've spent decades in geophysics and related disciplines, I've measured gravity, ground radiation, cosmic radiation, continent scale tides to determine mean sea levels, etc. )
