2030, Pudong River Estuary.
Nowadays, the Pudong River is becoming increasingly turbid, churning and roaring, like a trapped beast, tearing at the cage in front of it. At any time, it may swallow Shanghai, this country, or this planet.
The head of the 2048 Command said with a sad and somewhat impassioned face: "Global warming has become an irreversible trend. In the next fifty years, global sea levels will rise by about 10 meters, three-story buildings will be submerged, and coastal cities will gradually disappear. Therefore, I hope everyone will enter a state of alert and solve this problem as quickly as possible."
