Editor’s note: The chat’s now over, but you can replay it in full.


Alex Steffen, author, futurist, and founder of the (now defunct) blog Worldchanging, chats live with Grist Senior Editor Greg Hanscom on Thursday, Dec. 6 at 2 p.m. Eastern (11 a.m. PST) — and you’re invited to join the fun.

Steffen’s new book, Carbon Zero: Imagining Cities That Can Save the Planet, published over the last week in Grist and now available in Kindle edition via Amazon, is a brief but deep manual for imagining how our cities can become the solution to our climate woes.
