It's 2140, and the most popular reality TV show is a live-stream of Amelia Black transporting polar bears to the Antarctic in her airship as part of assisted migration. In New York, housing is run by cooperatives and buildings have been waterproofed below the high tide line. Sky-scrapers have had docks added part-way up for speed boats, and there are floors dedicated to food growing. This is the setting of Kim Stanley Robinson's New York 2140, a classic of post-climate fiction with an optimistic outlook.
