ST. PETERSBURG, Fla. — There's a giant, inflatable whale sitting in a Florida park this week, and it's more than just a public art piece.
The blue whale signals the arrival of the Blue Ocean Film Festival — one of the biggest environmental documentary events in the world — and also the rise of the emerging genre of cli-fi movies.
These movies aren't necessarily documentaries. The just-released "Interstellar" is considered part of the cli-fi genre.
Short for "climate fiction," the genre has environmental issues at its core. Many novels are set in a dystopian world where climate change has wreaked havoc on the planet.
There's even an online film festival called The Cliffies, which hands out awards to climate change movies.
