Global Warming and the Future

Global warming is real, and if ocean rise means NYC, Miami, LA, etc will all be flooded within 50+ years, then we’d better get going real fast in the central USA right now, because relocating every major coastal city before tidal rise isn’t going to be a 2 year project, and if we haven’t started planning the next super cities starting 3 miles below ground with the core infrastructure, we may already be too late.
