A while ago, I encountered a YouTube and Spotify playlist called "songs for an empty world" by LAIN. The description was especially interesting to me:
Only 250,000 people left. 160 days of sun in a year. Constant rain. Everything's green and overgrown. Welcome to 2131.
I was wondering what a world like this would actually look like. Would our trees and plant life actually survive and thrive with that little sunlight? Would the world become more of a fungal wasteland?
For the sake of this question, let's ignore the issues of flooding or how all that water would evaporate and get back into the sky, etc. I'm more curious if anyone with more botanical/scientific knowledge than I can give some educated opinions on what the biosphere would be like.
