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.
