Biome Temperatures Distributed Poorly

Currently, in 1.18 Experimental Snapshots 1 & 2 the distribution of biomes is not quite right (and I know it is a work in progress).

As amazing as world generation is now, warm, neutral, and cold biomes mix poorly. While exploring, especially in snapshot 2, I have seen many really warm biomes like Deserts and Savannah's mixing with colder ones, like the colder mountain biomes, extreme hills, taigas, etc.
