Biomes with vastly different temperatures generate next to each other.

Hello again, I saw a problem in a creative game that has to do with the generation of biomes. I was playing a creative game and I was traveling the world with elytras and I found a slightly strange generation because it was a forest, taiga and a glacier colliding on a sandy coast. according to me the generation had to have a "fictitious temperature" change like first desert then savannah then jungle then forest then taiga and finally glaciers. here my report and thank you for your attention
