I need to know which direction my story is going and what are my main points. The extra details will be improvised, but I like to have a fleshed out backstory to each main character, random notes about the backstory of the planet or setting, just things to keep me guided on my path.
I thought at first I would be a plantser, but I didn't quite think I fit the description.

Currently I have all my major conflicts, story goals, and a bunch of random notes finished.

The below spoil is just a random note/backstory on the setting for what I'm thinking, because I kinda wanted to put in a little Climate change agenda in there XD

-humans were run extinct by their own gains and deficiencies, leaving ruin in their wake. It took a couple thousand years, but earth had managed to heal itself somewhat, but not without damage.
The polar regions have changed to scorched cold deserts without water,the tips burnt from contact with space. The equator is a middle temperate zone. Rain forests and tropics no longer exist, as do many animals. (do more research)
