As Earth's climate rapidly declined, most parts of the earth have become uninhabitable to human life. Food supply chains broke down and famine was widespread. Disease and strife were the themes of this period. As major national governments broke down one after the other, people began to believe it to be the end of humanity. Instead of giving up, some countries decided to come together to form bigger political blocs. Old hatreds were abandoned in the common interest of collective survival. Major infrastructure projects were initiated to combat the changing environment. While they were successful, it was too little, too late.
