I had an idea years back about a story involving several friends in Brooklyn NY that had to suddenly flee from an oncoming tsunami. The cause was climate change related, the shedding of the Greenland ice sheet into the sea. They discussed the pettiness of their lives as they tried to escape the coming water. All the while news wires and half heard radio broadcasts altered and reminded them of their impending doom.
Alas if I was ever to finish it it would seem to come to late. The recent weather events are all the more potent reminders then the fiction I might have depicted.
