ClimateAdjuster

Allows patching biome climate data with a custom configuration. Schema for config/climateadjuster/climate_data.json is:

{

    "namespace:biomename": { // optional

        "temperature": number | null, // optional. See https://minecraft.gamepedia.com/Biome#Temperature . Range: [-0.5, 2.0]

        "temperatureModifier": "none" | "frozen", // optional.

        "downfall": number | null, // optional. Range: [0.0, 1.0]

        "precipitation": "none" | "rain" | "snow" | null // optional.

    }

}

If using Serene Seasons, prefer the “rain” precipitation type for compatibility with snow in winter.
