Equilibrium "Dawn of the Future"

Humanity is decimated by the effects of climate change. Hurricanes, shifted weather patterns … all affecting global energy and food production. In the past two hundred years, we have seen significant temperature changes, the Earth’s magnetic field has shifted (making solar radiation a real threat), and sea levels are rising as the Earth is rapidly warming up, even more than scientists expected. As a result of all these accumulating effects, the landscape transforms drastically. On top of all that, the melting of polar ice resulted in a new Little Ice Age in certain areas.

The remaining human population finds refuge underground. Forced by nature, they have to build habitable cities underground, saving them from solar radiation and other violent natural disasters. As time passes, humanity uses science to improve farming, energy efficiency, and offensive and defensive technology. To survive underground, psychology and sociology are studies that are also highly recommended. Going underground also reveals secrets from Dinas Emrys regarding vampires and their origins.

On the surface of Earth, nature has evolved in a more Jurassic form of life. The magnetic field has restored its protective nature, but due to unknown reasons, animals (and humans), insects, and plant life have changed drastically.
