Global warming is a survival map with a tropical island environment that you are constrained in. When you first load it up it will prompt you to set the difficulty, this changes how fast the water rises. You can set the difficulty again whenever you want, but by default the water rises 1 block every 5 items crafted. This project download is a server instead of a world because some of the mechanics require a java plugin. This is meant to be played on version 1.11 or 1.12, and you can play with as many people as your would like.
