'climate-active' is a modern compound word formed from 'climate' and 'active', where 'climate' refers to the long-term weather patterns and 'active' implies having an effect or influence.

The term 'climate-active' emerged in recent decades as awareness of climate change increased, combining 'climate' with 'active' to describe entities affecting the climate.

Initially, 'active' meant 'engaged in action', but in this context, it evolved to mean 'having an effect on the climate'.
