The basic concept of this planet is that, the planet has a tilted axis (you probably guessed that already) which results in the South Pole constantly facing towards the sun. This would result in the planet having a 'bi-polar' like climate, with everything from the North Pole down to the equator being a cold and frozen environment, getting warmer as you go south towards the equator, while everything South of the equator getting even warmer and warmer with the South Pole (if it is a present landmass) being absolutely scorching desert.
I'd imagine that the equator, being the halfway mark being hot-land and cold-place being somewhat humid and full of rainforest/jungles and plains. Though that is from my basic understanding of climates and planet related science. Mountains, rivers and so on would also above an influence on the terrain of the world. Wow an important distinction to make is that this planet isn't tidally locked, just it has a very wonky axis. So how plausible is such a thing, a little too outlandish or something entirely possible?
