I remember coming home after The War and seeing Earth again. But it was not as I remembered it. My home was gone of course. Yosemite falling had wiped it out. It was the cold that got to me. I’d grown up with cold. I knew what it was like to live at negative forty. American scale, not European. But what I came back to was something I’d never expected. We called it Nuclear Winter when I was young. What would happen to Earth if we ever let the nukes fly. Dust in the air. Global Cooling. Catastrophic environmental change. Mass animal die offs. Yosemite Winter didn’t hit all the checkmarks. We fought it real hard. But it was bad. Real bad.
