Under the Weather (The Believer): a bunch of climate activists in the West (who can afford to grieve about the climate crisis!) try to create a dictionary to describe climate-induced sickness and other maladies ("ennuipocalypse", "psychic corpus dissonance", "eco-pooper"). The project is a combination of philosophy ("because words forge the way we see the world") and politics ("because new words create new possibilities for action").

One of the words mentioned in this article is solastalgia, which is a certain type of nostalgia caused by environmental and psychological distress, founded in the relationship between the health of the land and the health of its people.  It's a portmanteau word of the Latin solus, which means “abandonment and loneliness,” and, yes, nostalgia.
In the language of Bruce Levine, the dissident psychologist, Chris is sick not because he is inherently anxious or depressed, but because he lives in a sick society in which both his belonging and survival depend on inaction. 
Maybe the word we need is not one for a sickness. Maybe we need a word for a difficult truth: that when the world is ending, our health depends on closing ourselves off to awareness of this fact.
