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

Sept. 12 is my birthday. I will be turning … old. So, so old.

As I was pondering this Life Transition, I said to myself, “self? You know what would be fun to do on your birthday? Chat with your beloved readers! They are, after all, the light of your life and the wind beneath your wings. Also, the election season is heating up, the climate issue is peeking out from behind the curtains, and the future of clean energy hangs in the balance. Also, the third season of The Walking Dead starts soon. So much to discuss!”

So drop by tomorrow, at 11 a.m. Pacific (2 p.m. Eastern), and click this link to join a live chat with yours truly. Consider it my version of the president’s “Ask Me Anything” on Reddit, only without the president. Or Reddit.

Grist thanks its sponsors. Become one.

See you tomorrow!
