This is the geographical map of my "Green Horizon" and "Unity" settings.

In a highly advanced state of affairs the super powers of the world entered a new arms race, using newly invented weather technology to create Climate Cascade weapons. The weapons caused massive devastating storms full of acid rain, particulate to block the sun, turbulent clouds. Two such devices were used and the effects were catastrophic.

The international weather grid, used to slow and in a few cases reverse climate change, was quickly adapted to stop the spread of the cascade storms. This massive requirement of power made the grid ineffective in the Americas and Africa, devastating the regions with higher temperatures and higher levels of UV radiation... but the storms were trapped.

Domed cities, Japan, and New York were the last elements of human cities left intact. Countless more domes hold humans in suspended animation waiting for a better day to emerge.
