'climate-destabilizing' originates from the combination of 'climate' and 'destabilize', where 'climate' refers to the long-term weather patterns of an area, and 'destabilize' means to make unstable.

'climate-destabilizing' evolved from the need to describe activities or phenomena that disrupt the stability of the climate.

Initially, it meant 'causing instability in the climate', and this meaning has largely remained the same in modern usage.
