Natural disasters & Dynamic climates

• Add Natural Disasters to the game
  • Frequency increases with global warming
  • Disaster types are tied to biomes (e.g. flooding can only occur on rivers and coasts)
  • Will destroy (ransack) district in impacted tiles
  • Can add infrastructures & districts to mitigate disasters (dams, waterbombers, Search & Rescue teams, etc)
• Add Dynamic Climate
  • Natural Disaster can modify tile type, including changing course of rivers
  • Natural cycles like "Little Ice Age" could spawn over a continent/world as a random event
  • Food yield can be boosted or lowered due to such climate event
  • Can add "Monsoon" climate mechanic where a continent gets bonus food yield at the expense of suffering from move associated natural disaster (conversely, some climate would be less prone to disaster but be poorer food-wise)
  • Can add "Trade wind" feature that would act like a road on water (and might allow non-ocean capable vessel from crossing ocean tiles if it has the feature)

To go along with these additions, agreements like "Humanitarian Aid" and additional events to offer help/gift to disaster stricken empires could interact nicely with this mechanic.
