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.

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.
