Let's say it's too late... we can't stop the icecaps from melting. Will the increased sunlight somehow evaporate all the water? How will the atmosphere be affected? If we don't lose the water, could we move underground? It should be cooler down there. Utilizing gravity, we could efficiently move water and other resources to our dwellings. With the extra sunlight, solar-panels should provide more than enough electricity to power whatever we need.
