On Winter Solstice 2021, NYC Microseasons was launched, an ongoing project I started with my friend Erin Chapman. Each week we are sending a newsletter marking the small shifts in the seasons across the five boroughs, reflecting on how both natural and unnatural forces are at work in New York City. The first season—The Solstice Arrives and Shadows Lengthen into the Darkest Days—is online now, along with ways to commemorate its passing. You can subscribe here for future seasons or follow along on Twitter.
