Science fiction has always been an outlet for our greatest anxieties. This week, we delve into how the genre is exploring the reality of climate change. Plus: new words to describe the indescribable.

1. Jeff VanderMeer [@jeffvandermeer], author of the Southern Reach Trilogy and Borne, on writing about the relationships between people and nature.

2. Claire Vaye Watkins [@clairevaye] talks about Gold Fame Citrus, her work of speculative fiction in which an enormous sand dune threatens to engulf the southwest.

3. Kim Stanley Robinson discusses his latest work, New York 2140. The seas have risen 50 feet and lower Manhattan is submerged. And yet, there's hope.

4. British writer Robert Macfarlane [@RobGMacfarlane] on new language for our changing world.

Throughout the show: listeners offer their own new vocabulary for the Anthropocene era. Many thanks to everyone who left us voice memos!
