Only the Li Fire and Profound Water Natures, whose essence is Qi Mechanism rather than physical substance, were capable of influencing the environment in the Early Stage.
Li Fire could raise the ambient temperature, making it feel like one was near a volcano, and could even be used to injure enemies.
As for Profound Water, it could drastically increase the moisture in the air, even conjuring water from nothing…
'Profound Nether,' a mutation of the Profound Water Nature, contained Heaven and Earth's Ultimate Yin Primordial Power.
It naturally followed that it would lower the ambient temperature…
It could turn a sweltering summer to winter, freezing running water solid!
'Of the five great Natures, it sounds like the water and fire types are a little more powerful, doesn't it?'
But that wasn't really the right way to look at it.
The water and fire Natures manifested externally, so they might indeed seem more powerful at lower Realms.
